The U.S. waste management industry moves more than 290 million tons of municipal solid waste each year. This is a potential trillion-dollar market, but much of the work still relies on paper tickets, clipboards, and spreadsheets. About 10,000 independent haulers handle a large share of collection and materials transfer in the U.S. In this business, a single truck costs $300,000, and profits depend on efficient routes. Most haulers do not have access to the digital tools that other logistics industries have used for years. Mike Marmo, CEO and founder of CurbWaste, is building a new operating system to change this. His goal is to create the data foundation needed for the circular economy to work. He is a fourth-generation waste industry professional who started his career as a scale operator at a family transfer station in New York and sold a hauling business in 2021. Since then, he’s built CurbWaste into a platform serving more than 150 haulers in 40 states. Its CurbPOS system for transfer stations tracks inbound and outbound materials with scale integration. It generates automated LEED diversion reports and Recycling Certification Institute-certified documentation; the per-load, per-material chain-of-custody data that extended producer responsibility programs need, as seven states now require producers to fund and document the recycling of their packaging.
Mike Marmo, Founder & CEO of CurbWaste, is our guest on Sustainability In Your Ear.
Mike made a simple but important point: “Waste is being created when it’s being manufactured.” The waste management industry reflects the economy and could become the base for a circular supply chain that keeps materials in use. Mike compares this to Amazon, which learned about buyer behavior and then built warehousing, freight, and delivery systems around that knowledge. The waste industry can do something similar. By tracking what is produced, where it goes, and where it ends up, haulers and new operators can work together on a shared digital system that gives full visibility of materials. Mike calls this the “waste meter,” and he thinks an AI-powered circular economy could be in place within 10 years. Accenture research estimates that the circular economy could add $4.5 trillion in economic output by 2030, a number supported by the United Nations Development Program. Right now, investment is far below what is needed to reach that potential. CurbWaste is working to build the transparency needed to connect collection and vision, helping turn a fragmented industry into a circular supply chain. To learn more, visit curbwaste.com.

Mitch Ratcliffe  0:00

Hello, good morning, good afternoon or good evening, wherever you are on this beautiful planet of ours. Welcome to Sustainability In Your Ear. This is the podcast conversation about accelerating the transition to a sustainable, carbon-neutral society, and I’m your host, Mitch Ratcliffe. Thank you for joining the conversation.

Today, we’re going to take another dive into the circular economy, this time about how we manage our waste collection and processing systems. The U.S. waste management industry moves more than 290 million tons of municipal solid waste a year. It’s a potential trillion-dollar market, yet much of it still runs on paper, tickets, clipboards, and spreadsheets. Roughly 10,000 independent haulers handle a significant share of American collection and materials transfer, and they work in a business where a single truck costs $300,000 and profitability depends on route efficiency. Yet most of these haulers lack access to the digital infrastructure that other logistics-centric industries adopted a decade ago.

Now that society recognizes the immense value in waste—that it’s not just something to dispose of as quickly and quietly as possible, to manage for profitable reuse in a growing circular economy—the waste management industry is in the midst of a vast upgrade.

And our guest today is Mike Marmo, the CEO and founder of CurbWaste, an end-to-end operating system built for independent waste haulers. Mike is a fourth-generation waste industry professional. His great-grandfather started in the business, and Mike started his career working at a family transfer station in New York. Then he built his own collection and disposal hauling company called Curbside, and when COVID shutdowns wiped out three months of construction-dependent revenue, he pivoted to focus on the software platform his hauling company had built. He sold that hauling business in 2021 and has spent the years since building CurbWaste into a platform that now serves more than 150 haulers across 40 states, from five-truck family operations to 200-vehicle regional fleets.

CurbWaste brings order management, real-time dispatch, route optimization, automated invoicing, driver apps, and e-commerce into a single cloud-based platform. Its CurbPOS point-of-sale system for transfer stations tracks inbound and outbound materials with scale integration, and uses weighted averages by material type to generate automated LEED diversion reports and Recycling Certification Institute certified documentation. In other words, it helps a hauler qualify for environmental incentives that gives contractors and developers defensible, third-party verifiable proof that their construction waste was actually diverted from a landfill. And that, too, creates another economic opportunity.

The per-load, per-material chain-of-custody data is what the emerging extended producer responsibility programs that we’ve discussed many times need, as seven states now require producers to fund and document the collection, sorting, and recycling of their packaging. So if you put this operating system under the circular economy, you start to track the value flow, and that means more value can be recognized and rewarded.

In October, CurbWaste closed a $28 million Series B round led by Socium Ventures—that’s the venture capital arm of Cox Enterprises—bringing its total funding to $50 million. The investment is fueling AI-powered business intelligence tools designed to give independent haulers the kind of data-driven decision making that larger competitors like Waste Management and Republic Services have built in their own proprietary systems.

We’ll talk with Mike about what it takes to digitize an industry that’s resisted technology adoption for decades, how CurbPOS’s materials tracking could extend from LEED compliance into EPR reporting and regional materials flow planning, and whether a network of independent haulers on a shared platform can become a connective tissue for an emerging circular economy supply chain. And finally, what is AI actually delivering for waste operations today compared to the hype we’re hearing?

You can learn more about CurbWaste at curbwaste.com—CurbWaste is all one word, no space, no dash.

So, can a software platform that modernizes independent hauling also help build the data infrastructure for the circular economy? Let’s find out right after this quick commercial break.

[COMMERCIAL BREAK]

Welcome to the show, Mike. How you doing today?

Mike Marmo  4:42

I’m doing well. How are you doing?

Mitch Ratcliffe  4:44

Doing well. It’s a beautiful day here in Southern Oregon, and I know in New York City you’re getting through the snow.

Mike Marmo  4:51

Yes, it’s really cold.

Mitch Ratcliffe  4:53

I want to start off with this question, and it goes back to the fact that your great-grandfather started this business, or started in this business. Walk us through the paper and digital processes that recycling operations have been using, and how CurbPOS changes their day-to-day work.

Mike Marmo  5:07

Yeah. So my family had grown up in this, you know, been in this business. I had grown up in this business. Actually, my first job, I was a scale operator starting at a transfer station. And when I was working there, everything was pen to paper. You know, we used a traditional scale ticket. We would put it through this, you know, the EXP printer.

And, you know, within that first year of really working there, I started to realize how difficult it was and how much manual work was happening. You know, a lot of the requests that we were getting at that facility—it was a C&D facility—a lot of the requests we were getting were for LEED, or for something that was related to a regulatory compliance effort, and to get all that information was fairly difficult. So we, you know, at that point, I really understood kind of where the waste industry was relative to the technology around me and my regular day-to-day life, and when I started a waste company, and then ultimately ended up starting a software company, I really saw it at scale, working with a lot of companies around the country that are starting pen to paper or operating off kind of archaic systems.

And so when we originally built CurbWaste and then the CurbPOS product, which is for the transfer stations and recycling centers, we really hyper-focused on automating tasks and making sure that everything was as digital as possible for aggregation of data. So I think we’re starting to see adoption along the way, and I think the waste industry is progressing, but ultimately, I think a digital experience is necessary. And I think it’s for the future of the industry and for the future of the way that we operate in our waste streams. I think it’s critical.

Mitch Ratcliffe  6:45

When you pivoted from moving trash to selling software, how did that change your view of the system that you’d been working in?

Mike Marmo  6:52

Yeah, so New York, obviously, is fairly unique. We were operating the five boroughs, and there are many limitations, regulatory compliance. It’s very difficult to navigate logistically—you know, so many people, and limited parking, limited space, very tight. So you know, when you’re operating in that bubble, you don’t have a lot of options on how you have to operate. You have to be really, really good and really, really pointed.

But then once we moved into the software space, and we started to see, you know, around the country, how people operate, the term I like to use always is “local,” because it really is. You know, we’re all fundamentally doing the same thing. We’re all picking up garbage. We’re all bringing it to facilities. They’re processing materials. But the way they do it, or the nuances around that workflow, are very different, depending on where you are.

And the example I’ll use is like, you know, you have New York City—again, that’s like a very tight space, limited space, lot of people. And then you’ll operate with a company down in Alabama or Mississippi that has a big urban sprawl, and they have different types of issues, different types of problems. And so everybody’s trying to do the best they can from a service perspective. But ultimately, it really is dependent on where you are regionally. And I think that’s where dynamic software and the ability to be dynamic really provides a lot of value overall.

Mitch Ratcliffe  8:04

The old approach to this business was you had a landfill and you had a certain number of years to fill it, and so you were managing filling a hole rather than extracting value from the waste stream. How have you seen that transition change the focus of the business that you’re trying to support with software?

Mike Marmo  8:21

So I think, I mean, maybe I can take a step back into the history a little bit. To your point, I think waste used to be volume-based. It was very much like, I charge a price per yard, I dump for price per yard. And there was a simplicity in that. But I think it also led to—kind of, the way that pricing was done was, again, very volume, and it was very simple.

When the industry moved into weight and it started to weigh materials—and obviously within that, the kind of correlation of commodities being pulled out and the value in the global supply chain—there was a shift in the industry where some of the waste haulers still were pricing or stuck in a volume-based framework, but the facilities were pricing off of tonnage.

And there was an evolution that happened over time. So what you end up seeing is like, if you order a dumpster, for example, and a dumpster has a certain amount of price and allowable tonnage, and then you’re pricing off a matrix format for additional tonnage—the industry shifted. There was a shift in the way that the industry actually started to work.

So now what ends up happening in that framework is, some landfills, you know, big facilities, certain markets have a lot of land and a lot of sprawl, and they have big holes with long lifespans. Whereas other markets don’t have any landfills, or have many landfills closing because they’re running out of space, and they’re moving to intermodal, or they’re moving to, again, like MRFs. There’s been more focus on bringing materials back into the supply chain. So I think we’re still seeing that shift happen. It’s still moving in that direction.

And I think, again, like I always say, waste is a utility that’s not measurable, and I think that’s the main problem. And in order to do this well, you need to have a unit of measurement, a single point of truth. And so that’s why I think software comes into play. It’s able to aggregate a bunch of data—operational data, but also data that’s related to the material and waste streams—and be able to measure what’s going on, and then be able to make better business decisions and better regulatory decisions on the long term.

Mitch Ratcliffe  10:23

CurbPOS tracks inbound and outbound materials at these transfer stations. When a truck dumps a load, what’s the data capture process, and how granular does it get in terms of the materials that you can classify and identify? And then what does that enable in terms of value extraction?

Mike Marmo  10:38

It all depends. It really depends on the market. Some, it hits the floor and then it just gets, you know, taken out to the next place. Other markets will obviously run it across a belt, pull out commodities. So there’s something measurable that’s happening.

I think, you know, the age of technology now, you can do things like material recognition—AI being able to do material recognition and get components of that. Obviously, the certification bodies like RCI and LEED that are helping to kind of audit and make sure that there’s an evaluation period of whatever they’re saying they did, or whatever they’re pulling out of the stream.

But the inbound-outbound correlation is really what matters. Because when you’re coming onto the scale and you’re getting weighed and you’re putting it on the floor, once it hits the belt, we can then take the outbounds and create that mapping of, okay, this material, amount of material came in that day, this load hit the floor, and then this is what was distributed out. And then we can show you what a recycling rate was. I still think there’s more to be done there. I do think that cameras and AI can measure that when it hits the ground, but I think the industry is moving in the right direction overall.

Mitch Ratcliffe  11:52

Let’s step back a little bit from the industry to, let’s say, a five-truck family operation that’s never used anything except maybe QuickBooks to do some invoicing. What is the actual on-ramp to CurbPOS look like for them? How does it change their business?

Mike Marmo  12:09

Yeah, so I think if you’re a hauler, you’re going to be on the CurbWaste product. If you’re transitioning to be on the CurbPOS product—but really, around implementation, I think that’s actually a natural point where people start thinking about software as a hauler. You know, you really want to be cost-efficient in the early days, and so sometimes software might be out of the price range. But I think as you start to grow, and you’re seeing that incremental growth, what most haulers are looking for at that point is efficiency and visibility.

So what software is able to do—operationally, it’s allowing you the ability to be efficient and to be able to see what’s working and what isn’t, and then it’s also giving you insights into what’s measurable, so that you can keep investing in the things that are working. That’s hard in the waste business overall, but it’s a good way to start.

When you go through change management, change is hard all the time. Like, if you have a process that’s working, and it’s, you know, the kind of old adage, “If it ain’t broke, don’t fix it.” You hit a certain point where you have to make a decision about what you want—what is the motivating factor of the business? So are you trying to grow, or are you just trying to maintain where you are? Most people that are entering business and entrepreneurship are trying to grow. So then it becomes about scale. It becomes about, I need to maximize and focus on the most important thing, and I can’t do everything. And eliminating manual tasks allows you to scale more efficiently.

So you go through the buying process and you find the right fit for the software that you need in the moment of which you need it. But you also need to consider what you can scale into as you grow. And then you go through a process of entering orders, getting training, training the drivers, training the staff, making sure everybody understands how the system works. But then there’s a transition period. We stick with them, we make sure that everything is going the way that we hoped it would go, what the project plan said, and you’re supporting them along the way. But at a certain point, the system is running for you, and then they’re off to the races and they continue to scale.

Mitch Ratcliffe  13:53

One of the major changes in the industry that’s driving this transition is the introduction of extended producer responsibility laws, which require, for instance, you’re measuring material type, the weight, its recyclability, and whether it’s recycled, and getting verification of that diversion from landfill. Was that in your head when you started thinking about developing CurbWaste, or is this an opportunity that’s just sort of emerged conveniently at the same time?

Mike Marmo  14:20

100%. When we got into this, the grander vision was the interconnectivity of the supply chain from a data perspective. So the way I kind of like to normalize it is, you have a generator, you have a collector—a hauler—you have a disposal site, and then ultimately end use, right? But it’s end of life. So does it go back into the supply chain through the circular economy? Does it end up in the hole? Whatever that is. There’s usually that period of time where the life cycle has ended.

So the way we thought about it was, well, where can we focus energy from a software perspective? I view the haulers and the transfer stations and the disposal centers as the core of the data set. So we really want to be hyper-focused on aggregating data and providing value in those areas. But ultimately, the idea was to interconnect the generation piece to the rest of it. So when we started, we really stayed focused on that part—the collector and the disposal. But now we’re starting to migrate into the generator piece, to really connect the data sets. And to your point, show where material is being generated, how it’s being generated, where it’s going, and ultimately where it ends up. That’s the measurement of the utility. That’s the waste meter. And that’s what we’re trying to achieve.

Mitch Ratcliffe  15:31

We’ve had a number of sorting and hauling folks on the show, as well as a lot of other thinkers on this topic of the circular economy. So building on this reality in which you’ve got verification that materials have been moved to a particular place and at a particular pace, do you imagine it’s possible to actually plan regional material flows, to really turn the circular economy on in its full flower?

Mike Marmo  15:55

Yes, I do. It’s a lofty goal. A lot has to happen. But I do believe that that’s possible. And the analogy I like to use is something like Amazon. Amazon was able to understand from a retail component, like, what buyer behavior was. They were able to leverage data around buyer behavior, and then they were able to integrate themselves into the supply chain—the freight forwarding, the warehousing, the ultimately last-mile delivery.

And they do it so well. The reason why you’re able to get something in the same day is because they were able to connect all those pieces and understand the output. I believe that the waste industry can achieve that. And so that was a core part of what we are trying to do. You have to walk before you run. You can’t do everything all at once. And again, this is a business, right? Like, if I sign up a hauler and I can’t run their business, then the workflows—you have to build a foundation before you build the house. But I think the long-term vision is the ability to do exactly what you just said.

Mitch Ratcliffe  17:03

Millions of people come to Earth911’s database to find out what to do with specific materials, and one of the things they’re interested in is getting the right material to the right place, so that it is actually recycled. And what you just described in the context of Amazon, for instance—should we not be thinking about putting everything in a single bin? But could we, in an economically viable way, actually have specialized collection that would produce a cleaner load?

Mike Marmo  17:33

Yeah. I mean, one of the things that I saw as a waste hauler that I struggled with was, we’re making decisions—whether regulatory or whether it’s, you know, just in general—like, if you’re trying to be a good actor and try to do the right things, but it’s not rooted in much data. And so what I tried to say was, well, if we can’t measure it, then how do you action it?

And I think the first step, the first thing that everybody should be paying attention to is, how do we measure this? Like, what are we actually looking at? What is the scope of the effort? I don’t think anybody could tell you that, but I think there are ways to do it. And I think, as you have—we like to refer to ourselves as a system of action. You have to have a single point of truth. And when you have a single point of truth, you can then make action against it. So data is the most important thing right now. Data aggregation is the most important thing.

To your point, you did say something that’s really important that I think gets missed as well, which is, it has to be economically viable. There has to be ROI associated. And so a lot of times, what ends up happening is you get a compliance or regulatory effort that doesn’t really take into account the business criteria, and then people are resistant to it, because the business still has to run—it’s a for-profit entity. We want to take the opposite approach. We want to provide value and find ROI in the haulers’ work. Work alongside them, work alongside the transfer stations, work alongside the landfills. Understand how they’re thinking about their business, and really get down into the KPIs of their ROI, and then funnel that back up to the generators and say, here’s how they make money, here’s what’s valuable to them. How can we work together to make that make sense?

I think there’s a way to do that, and it’s just about visibility. It’s transparency, it’s visibility, it’s getting people on the same page. And working together is really what we need to do.

Mitch Ratcliffe  19:05

So here’s a hypothetical. Let’s say you look to the one organization in the world right now that has the greatest visibility into what’s flowing into homes, and that’s Amazon, like we were just talking about. Could you partner with Amazon to say, we know you’re delivering this much cardboard, this much plastic waste, and so forth into this region, and then plan a hauling solution in response to that?

Mike Marmo  19:29

That’s right. That’s the end goal. That’s probably the last step, the last piece of the puzzle. But that’s exactly what you want to do. You know, waste is being created when it’s being manufactured, right? Like, ultimately, when it starts, at that point is when we know what the waste stream is going to look like. But again, if you have nowhere for it to funnel in, and you have nowhere to measure it, it’s disjointed. You have to have an integratable solution to be able to even do that. So yes, that is the goal. But ultimately, we have to start at the foundational level.

Mitch Ratcliffe  19:58

Yeah. We’re moving to a more planful economy, and there’s a lot to unpack in that idea. Let’s take a quick commercial break. We’re gonna come back to this fascinating conversation. Folks, stay tuned.

[COMMERCIAL BREAK]

Welcome back to Sustainability In Your Ear. Let’s return to my discussion with CurbWaste CEO Mike Marmo. He’s a fourth-generation waste industry veteran whose AI-augmented CurbPOS system automates recycling operations. So, Mike, until recently, the waste management industry has been resistant to digitization. Let’s just put it that way. And there’s a massive change ahead. What do you see in terms of a new generation of leadership and the way they think emerging as this industry grows?

Mike Marmo  20:43

Yeah, I think tech adoption in general runs through cycles, right? You have your early adopters, people that see the value. Usually, that’s someone that understands that they have to differentiate. That’s helping at the market. I was at that at one point—when you’re competing with 200 haulers in New York, you have to figure out a way, right? So tech, for me, was the way that I differentiated myself.

So you start with those, and what you’re really doing is you’re proving the ROI, you’re proving the case. You’re building case studies around, okay, this is providing value in this particular area, but you’re also identifying the meaningful pain points of what they’re experiencing. I think a lot of times, if you talk to a waste hauler, maybe generally they’ll say, like, things are working. But if you really get down into it, pull back the layers, there’s always a pain point. There’s always something they’re trying to solve for.

But when you see margin shrinking, you have to either try to drive net new revenue, or you have to be able to save in a certain area. So then what ends up happening naturally is that people start paying attention and they say, okay, this person is growing. They’re growing 30% year over year. What’s driving that growth? And eventually you get adoption. In that way, you get that mass adoption. But some people don’t want to take the risk. They want the other people to take it first and have that proof point. But then it kind of accelerates, and that’s when you start to get into that hyper-growth, hyper-adoption phase.

I think we are very, very close to that. I think what’s happening is people are paying attention to what’s going on. From a tech perspective, it is moving at hyper speed at this point, and so the world is evolving at such an incredibly fast rate that anybody that doesn’t adopt will ultimately fall behind at some point. So I think the waste industry historically has been a little behind, but I don’t anticipate that being the case for the long term.

Mitch Ratcliffe  22:23

When you raised your Series B, you said that you wanted patient capital that understands that this industry won’t transform overnight. And in the context of what you just said about everything changing at hyper speed, why patient? And how does that transformation happen in practice? And what do you see as the timeline?

Mike Marmo  22:41

It’s pretty simple. I think I alluded to this earlier. You have to build the foundation before you build the house. You can’t build the roof first, right? You have to build the foundation. And a lot of waste haulers—you have a varying degree of waste haulers around the country that are like two-to-three-truck operations all the way up to 30,000-truck fleets, right? So you have to meet them where they are. If you cannot run the business for them in a meaningful and impactful way, then you’ve already failed. There’s nothing that you can do that will really help them unless you pick a niche part of their business. And we have a lofty goal of being an operational management system. We want to be able to run the entire business on the platform.

So you have to start there. And when I say patient capital, there’s a lot of effort that goes into building those workflows, not just surface level, but adding depth, adding nuance and depth, to make sure the system is dynamic but rigid. You don’t want data to be wrong, and you don’t want it to get convoluted, but you want it to be dynamic enough to meet the need in the market. So that takes time. You have to learn. You have to listen. You have to pay attention to what’s going on. You have to be a really, really good partner to the waste hauler. They have to trust you and believe in you.

So that part of it is like the first step into the rest. But in conjunction with that, you have to be forward looking. You have to be looking at the things that they’re not paying attention to, the things that they don’t know, because they’re in the weeds dealing with the day-to-day. They’re dealing with servicing their customers, they’re dealing with the community, they’re dealing with building the business that they’re focused on. So it’s our job as a tech partner to be able to say, this is where the industry is moving, here’s what this is going to lead to, here’s the vision, and hopefully get people to sign up to that and believe in that.

So when we brought in a partner, we articulated that. I think a lot of times, when you bring on venture capital or any funding, they’re expecting this major hyper growth. But if you want to achieve what we’ve been speaking about thus far, you need to get things right, and you need to make sure that you’re building the foundation correctly.

Mitch Ratcliffe  24:40

You’re leaning into AI. Does that mean that you’re training models to become an expert in managing waste or hauler processes? Where’s the focus of your training?

Mike Marmo  24:51

It’s really in a couple different areas. I think what we really preach out there in the market is, AI for the sake of AI means nothing. Like, AI is cool. It’s great. It can provide you really meaningful value in certain areas of your life. And I think it’s going to be transformative, without a doubt. But in our industry, waste haulers don’t really care about necessarily putting something in because it’s flashy and nice and cool. They want it to provide value.

And so when we think about AI, we think about manual tasks. We think about repeatable tasks. We think about infinite-scale areas of their business that we’re solving an immediate pain point, or that they can scale with for the remainder of time, because that thing is going to happen all the time. So an example of that would be, how are we ingesting orders from multiple channels to create efficiencies? How are we setting up call centers? How are we transcribing phone calls for customer support and customer success?

And then I think what you’re referring to on the learning side is the gluing of traditional machine learning and algorithmic types of optimizations—for example, like route optimization—gluing it to historical behavior and being able to say, here’s the nuances, here’s when the person never puts their garbage out on time, here’s where this street is closed, but it doesn’t show you that in the map. Just certain things that dispatchers know, that tribal knowledge, that they understand their market, that an algorithm is not going to understand. And that’s where AI can layer in and learn behavior and then make better recommendations.

So it’s not an overnight thing. You have to have the data. It’s only as good as the data. So we’re really focused on the infrastructure architecture, making sure that we’re aggregating that data appropriately, and then learning on that data in order to make sure that we’re giving them the best option for success, or the best decision-making process, or the most optimal insight that we can provide.

Mitch Ratcliffe  26:42

So what’s an example of an AI-driven recommendation that one of your haulers has used to make a decision that they wouldn’t have otherwise?

Mike Marmo  26:50

Yeah, I think, like, operationally, or just anything that we can do that’s kind of AI-powered—

Mitch Ratcliffe  26:56

One that was a material difference for the hauler. What do you point to as an example when you’re talking to other haulers?

Mike Marmo  27:04

Yeah, let’s—I’ll probably say two. I think first, let’s just talk about—we’ve talked about change management. I think right now, internally, we’re really hyper-focused on making sure that we can create a really nice change management experience of adopting software. So we do a ton around AI data migrations, so that when we’re taking data out of a system, we’re able to map it in a quick and easy way that they can understand it, but also do structured cleanups of that data to make sure that they’re getting what they want into the new system. It seems like a small thing, but it’s a very challenging thing when you’re going through a long change management process. So that’s an immediate impact to the hauler, that they feel more comfortable in that change.

The second thing is, anything agentic that we build is going to provide value to the pain point that they’re trying to solve for. So whether that’s migrating data from one place into another—being able to take data out of a CRM or being able to put it into an ERP—meaningful value. You’ve just eliminated a manual task that they would have to do over and over and over again. That’s repetitive, that’s manual, and it applies. So it’s a really good method in providing ROI, because you can just say, that work is never going to be done again. That agent will work in that and do that for you with conviction.

But I think longer term, things like we talked about—service verification, material recognition, route optimization—those are efforts that we have to make meaningful investments in, that’ll be coming down the pike.

Mitch Ratcliffe  28:29

You know, as I listen to your description of this, and I think about the U.S. recycling system, which is, as you’ve pointed out, filled with small, private recyclers and haulers looking for ways to plug into, for instance, the growing extended producer responsibility infrastructure that’s emerging around us—I’m reminded of eBay. Is CurbWaste aiming to become a marketplace layer where those independent operators can begin to identify and plug into broader materials flows?

Mike Marmo  29:00

It’s on our radar. Like I said, I think a marketplace, to me, again, is really indicative of the behavior and the learning and understanding what’s going on. So right now, core focus is just visibility. I think we have to create the transparency layer first before anything else.

But yes, I would say, a marketplace, the ability to understand who’s best—like, RCI is a great example. I mean, RCI, when you’re partnering with LEED and you’re trying to find RCI facilities to establish those LEED points, that’s an area where we can help and say, this facility is in this area. Partner. We’re driving revenue for our customer base. We’re saying this RCI facility is on our platform. We can measure it. We can automate that process. We can get that LEED report to the right person in the right moment and give that level of visibility through dashboards or anything that we’re building at a customer-facing level.

Again, that’s work that doesn’t have to be done manually. That’s something that can happen in automation. That’s probably the first natural step. And we are doing some meaningful work with RCI and LEED. But long term, I think, yes, to your point, we want to get to a visibility layer, a waste meter layer, for anybody that wants it.

Mitch Ratcliffe  30:10

That transparency that you’re describing is going to be particularly important to producer responsibility organizations, the entities that are standing up to fulfill EPR requirements. Are you talking with them about how you can facilitate the management of their specific materials?

Mike Marmo  30:28

Yes, we are very much in discovery and in conversation with people that are obviously interested and incentivized to want to work with us and try to achieve this vision. So we do talk to people, and we do try to understand, what visibility do they want? What would they love to see? What is a utopian point of view? I mean, product is always something that we’re always forward looking on, right? What’s being built today is actionable. It’s already been validated. Now it’s about, what are we going to build in the future? We’re probably talking a few years down the road. I think we still have a lot to do on the workflow side. But yes, we are always keeping these teams informed and making sure that they’re aligned with where we’re going.

Mitch Ratcliffe  31:06

You’ve raised $50 million to date. Do you see a substantial amount of capital sitting out there waiting for this efflorescence of data visibility to take hold, so that they can begin to mine the material value in the economy?

Mike Marmo  31:21

Yes. I mean, our Series B was led by the venture arm of Cox Enterprises, and it was a very big part of their thesis. They saw the vision. They aligned with it. We were able to move quickly. But it really was rooted in the fact that they’ve been seeking this type of solution internally. They’ve been trying to figure out how to get more visibility into their own efforts as it relates to sustainability. So yes, I think we will continue to build. We have to fund the business in order to build the products and achieve the dream that we want to. We do believe that this can be a very big business, but ultimately, we are still aligning on that mission statement and that vision of giving the true visibility and measurement of the waste industry.

Mitch Ratcliffe  32:00

We’ve been looking kind of over the horizon without a clear timeframe. But let me ask you this: in 10 years, will we have an AI-enabled circular economy running, or will it still be in the process of being constructed?

Mike Marmo  32:12

I think it will be there. Yeah, in 10 years, I think it will be there. I think, you know what I know internally of where we are—we are not that far off. We have spent the last four years on the workflows. We are starting to see the data benefit of that. I think in the next 10 years we will 100% have it.

Mitch Ratcliffe  32:33

So how does that change the economy of the United States?

Mike Marmo  32:37

You know, that’s the part that I’m not 100% sure. I’ve been operating under the mission statement of this dream and this vision. I do think that it’s going to ultimately make us rethink how we think about waste.

You know, you have electricity, right? You can measure it. You can go onto your portal and see how much you’re consuming. You can measure water. You can measure all the things that you’re using on a day-to-day basis. The waste industry is a part, a core part, of our infrastructure. It’s a core part of our society. You can even look historically and say, when waste stops getting picked up, it can crumble a society. It can crumble a city. I mean, New York City went through that in the strike, and recently in Boston they went through it.

So there’s meaningful implications to the societal impact that waste has. And sometimes I think that gets taken for granted. And I think what we really want to focus on is showing that—getting all the waste haulers in our community, which I really think we’re building, is a really great community of waste haulers that are forward thinking, that want to be a part of that mission, and try to show people how critical this industry is, and also all the things and all the information and insights that can come out of it.

So yeah, it’s very mission-driven. It’s a very personal journey. It’s a very mission-driven journey. But ultimately, I think we have to break it down into its parts, phase out what the goals are, and then get to a point where we can show people how important it actually is.

Mitch Ratcliffe  34:05

This is a huge vision. How can our listeners keep track of your part of the story?

Mike Marmo  34:10

Well, I mean, obviously we post whatever we have to post on our website, so that’s a good place—at curbwaste.com—but also, anybody can reach out to us. I mean, we are very much trying to be an advocate of the industry, and we’re very much trying to be people that can be thought leaders and really speak about what we’re trying to achieve here. We’re very transparent, we’re very honest, we’re very true to who we are. So we love interacting with people in the space. We have people come to our office often. We have people talk to our team often. So for me, it’s reach out. Reach out on LinkedIn, reach out on the website. You can reach out by any means necessary.

Mitch Ratcliffe  34:48

Mike, thanks very much. It’s been a really interesting conversation.

Mike Marmo  34:52

Thank you. I really appreciate you having me.

[COMMERCIAL BREAK]

Mitch Ratcliffe  35:08

Welcome back to Sustainability In Your Ear. You’ve been listening to my conversation with Mike Marmo. He’s CEO and founder of CurbWaste, and a fourth-generation waste industry professional who’s building the CurbPOS system, an end-to-end operating system for independent waste haulers. You can learn more about the company and its work at curbwaste.com—CurbWaste is all one word, no space, no dash.

Mike said something during the conversation that I encourage you to sit with: waste is being created when it is being manufactured. Now, that’s a deceptively simple observation, and it reframes everything with regard to how we think about the leftovers of the take-make-waste economy. The moment a product rolls off the line, its waste stream is determined—its packaging, what you need to do with it, the end-of-use disposition of the product itself, and the materials that will need to be collected, sorted, and either returned to the supply chain or, unfortunately, sometimes buried in a hole. If you can accept that premise, then the waste management industry isn’t simply a downstream result of the current economy. It’s a mirror that we need to look into to see the potential value to be recovered next week, next month, next year, or decades from now, when materials can no longer serve their current purpose.

Mike also pointed to what happens when waste stops moving. In 1968, New York’s sanitation workers walked off the job for nine days—just nine days—and 100,000 tons of garbage piled up chest-high on sidewalks. Rats swarmed into the city’s best neighborhoods, and New York declared its first public health emergency since the 1931 polio epidemic. And just last summer, when Teamsters struck against Republic Services in the greater Boston area, trash went uncollected for more than two months across 14 communities. Dumpsters overflowed behind restaurants. The rodent population exploded, and schools faced the start of their school year buried by rotting waste. As Mike put it, when waste stops getting picked up, a society can crumble.

And that fragility reveals something profound about society’s relationship with the materials from which it is constructed. We’ve built a civilization on the assumption that waste must disappear—that it’s someone else’s problem, and that it is best put out of sight and kept out of mind. We’ve treated waste as dirty, shameful, and beneath notice. That cultural contempt has real economic consequences, because it means we’ve systematically underinvested in the infrastructure that manages the material afterlife of everything that we produce and consume.

Now just imagine what happens when waste is no longer something to dispose of, but something that it’s important to recover. When the 290 million tons of municipal solid waste moving through U.S. systems each year is finally understood not as a cost center, but as part of the supply chain—a feedstock stream worth tracking, optimizing, and monetizing with the same sophistication we bring to any other logistics challenge. That’s when the world CurbWaste wants to enable and its staggering economics will come into being.

Accenture research projected that the circular economy could generate $4.5 trillion in additional economic output by 2030 and as much as $25 trillion by 2050. The United Nations Development Program has endorsed that same $4.5 trillion figure, noting that the transition would simultaneously cut emissions, create stable jobs, and open new green markets all over the world. Market analysts are converging on figures that describe an enormous circular economy. King’s Research projects it will reach nearly $2.9 trillion by 2031, while a more conservative estimate from Next Move Strategy Consulting pinpoints $1.3 trillion in projected value by 2030—so that even the lowest projections represent a doubling or tripling of the current waste market’s value in just five years.

The point is that we’re dramatically underinvesting relative to the opportunity. CurbWaste’s CurbPOS is just getting started on the path to connecting waste generators to local haulers, closing the loop that Mike described, from the point a product is manufactured to the end of its life and, ideally, back into the supply chain.

Mike’s Amazon analogy is the right way to frame this. Amazon took the time to understand buyer behavior first, when they were just selling books, and then they connected warehousing, freight forwarding, and last-mile logistics based on the knowledge of the consumer’s needs. The waste industry can follow the same logic: identify what’s being generated, where it flows, and where it ends up, ready for collection. Then the challenge is plugging the myriad gaps in our collection infrastructure by connecting independent operators—new startups—to materials that they can monetize, using a shared digital infrastructure. Right there you can see the necessary transparency layer, the marketplace layer, that turns a fragmented collection system into the connective tissue for a circular supply chain.

And that’s the signal that can transform waste into value, and that will drive new revenue for state and local collection and processing companies under extended producer responsibility programs, and ultimately lead to planned regional materials flows that citizens don’t pay for, that companies exploit because it’s profitable.

So when waste stops being considered the dirty result of our consumption and starts being recognized as valuable—when society looks at what it throws away with the same interest it brings to what it buys—we will have a fundamentally different relationship with the material world. One that recognizes that the people who move and manage our waste are operating a utility as essential as electricity or water. And that’s the story that will help unfold and explore here on Sustainability In Your Ear.

So stay tuned. And folks, would you take a moment to check out our archive of more than 540 episodes of Sustainability In Your Ear? We’re in our sixth season, and I guarantee you there’s an interview that you’ll want to share with one of your friends.

8 Best Non Toxic Lotion Options For Smooth Skin

Published

on

Last Updated on March 4, 2026

Not every lotion is created equal. If you read the ingredients list on conventional lotion, there will likely be many ingredients you can’t even pronounce.

While this doesn’t necessarily mean danger, it should make you question what’s in your skincare products.

8 Best Non Toxic Lotion Options For Smooth Skin

Some of the links in this post are affiliate links; for more information please see my disclosure policy. 

Skin is the largest organ. It’s our body’s first line of defense against pathogens and environmental hazards, so what we put on it matters.

That’s why I’ve curated a list of non toxic lotions your skin (and the planet) will love.

what ingredients should I avoid in lotions?

You should avoid ingredients like parabens, phthalates, fragrance, and mineral oil in lotions.

Here’s a break down of why:

  • Parabens: Used to preserve lotions but can disrupt hormones and have been linked to breast cancer
  • Phthalates: Used to make fragrances last longer in lotions but can disrupt the endocrine system and have been linked to reproductive problems
  • Fragrance: Tends to be artificial and the word ‘fragrance’ can entail a cocktail of hundreds of chemicals linked to triggering allergies
  • Mineral oil: Used to create a protective barrier to lock in moisture but is petroleum based and may clog pores

Instead, look for natural, organic ingredients that you can pronounce or research with ease. Ingredients like aloe vera, jojoba oil, and cocoa butter are just a few great places to start.

EWG’s Skin Deep database lets you search brands, products and ingredients, scoring them by hazard (10 being the worst).

8 Best Non Toxic Lotion Options For Smooth Skin

how can I tell if a lotion is truly non-toxic?

To tell if a lotion is truly non-toxic, you’ll have to read the ingredients label. It’s also important to understand just because it has natural ingredients, doesn’t mean you can’t have an allergic reaction.

For example, many people love coconut oil, a natural ingredient, but some people are allergic to it and cannot use any product that contains it.

You also want to look for brands that utilize organic, plant-based ingredients and have certifications. For example, being EWG Verified or MADE SAFE means it was third party tested, which ensures better quality ingredients were used.

But beyond ingredients, it’s equally important to look at packaging. Avoiding single-use plastic as much as possible is ideal.

Endocrine Disrupting Chemicals (EDCs) have been found in many plastic products. Microplastics have also been found in our blood, feces, and even placentas. Always prioritize lotions with low waste or refillable packaging when possible.

what is the most non-toxic body lotion?

The most non-toxic body lotions are listed below. None of the brands listed here use fragrance, parabens, or other harsh chemicals. And many offer plastic-free and/or refillable packaging.

I’ve gone ahead and highlighted some of my favorite features of each brand, but it isn’t an exhaustive list. Be sure to check out their websites for more information.

Sustainable Roofing Buyer’s Guide: 2026 Update

Published

on

For most people, buying a new roof is one of the most important and expensive maintenance decisions for their biggest investment. For many homeowners, the cheapest option is the default choice, while others choose a style they like and leave the details to a contractor.

It’s not always easy to find out who makes your roofing material. It can be even harder to find out if they recycle or work to minimize their environmental impact. But the impact of our roofing choices, both on our homes and on the environment, is too great to ignore.

We’ve researched roofing materials and manufacturers to make it easier to buy an eco-friendly roof. Our results are far from comprehensive, but as more consumers begin to demand this information, more manufacturers will begin to provide it. When they do, we’ll update our sustainable roofing results.

Materials

This article looks at the pros and cons of the most common manufactured roofing materials. We don’t include natural roofing materials in the comparison chart since they aren’t manufactured.

Asphalt Shingle

Asphalt is the most affordable roofing option. It’s so common that when people talk about roofing, they often mean asphalt shingles. About 75% of single-family homes in the U.S. have them.

Laminate shingles (also called architectural or dimensional) are fiberglass layered between asphalt and ceramic granules. They can be made to look like more expensive materials, such as tile, wood, and slate. Although slightly more expensive than basic three-tab asphalt shingles, laminate shingles perform better. Single-plane shingle roofs (also called 3-tab) are the easiest roofs to retrofit with a solar panel system. Several asphalt tile manufacturers offer solar-compatible or solar-integrated asphalt roofs.

Asphalt roofs usually last 20 to 25 years, but some newer, high-quality ones can last 40 years or more. While asphalt shingles can technically be recycled, most still end up in landfills. The shingles recycler, GAF, report that over 13 million tons of asphalt shingles are removed from U.S. roofs each year, and less than 10% are recycled. The rest go to landfills, where they can take 300 to 400 years to break down.

On the bright side, shingle-to-shingle recycling is improving, with CertainTeed’s RenuCore technology and GAF’s RoofCycle process helping to create more circular options for asphalt shingles.

Wood Shingle and Shake

Handmade wood shakes are valued for their natural appearance and are known for being expensive. However, machine-made wood shingles cost only a bit more than asphalt. Wood shingles can develop mold, split, or rot in damp climates.

Untreated wood shakes don’t have a fire safety rating, so many places with wildfire risk don’t allow them. Fire retardants can help wood shingles and shakes reach a Class B fire rating, and adding extra materials to the roof can help them meet Class A standards. Chemically treated shingles can’t be composted. Even with these issues, wood roofs can last 25 to 30 years, and with careful upkeep in mild climates, they may last up to 50 years.

Getting wood shingles or shakes from a local sawmill cuts down on greenhouse gas emissions from transport and ensures the wood species fits your region. Whether you buy locally or from a national brand, look for FSC-certified wood.

Metal

Metal roofing options include steel, aluminum, copper, and alloy strips. They come in various shapes and textures, from standing seam panels to shingles that resemble tile or slate. Metal can be more expensive than asphalt, but, except for copper, it remains among the more affordable long-term roofing options when lifecycle costs are considered. Proper installation and good insulation are required to minimize noise from rainfall and wind “chatter.” Metal is lightweight, virtually fireproof (Class A fire rating), and particularly suited to solar panel systems. Metal roofs last 40 to 70 years or more, and they are the most easily recycled roofing material, as metal is 100% recyclable at end of its useful life as roofing.

Tile

Tile roofs are common on Mission and Spanish-style homes in the western and southwestern U.S. While they’re often found in desert areas, some tiles, like Ludowici’s that meet ASTM C1167 frost-resistance standards, can be used in cold climates too. Roof tiles can be made from terracotta clay, ceramic, or concrete. Tile roofs are heavy and may need extra framing. Concrete tiles cost less than clay but offer many of the same benefits. Clay tile roofs can last 50 to 100 years or more, while concrete tiles usually last 40 to 50 years.

Slate

Slate roofs are heavy enough to require extra framing. As arguably the most expensive roofing material, they are not an option for most budgets. But they are also nearly indestructible, with a lifespan of 50 to 100 years or more. Be aware of the origin of the slate that will be used, as the sustainability and durability can vary. Because slate is so heavy, the distance slate tiles must be shipped will significantly affect not only the cost but the environmental impact of choosing this natural material.

Synthetic Roofing

Synthetic roofing can be made from materials like plastic, clay, rubber, or asphalt, and is often designed to look like natural materials such as slate or wood. Thermoplastic polyolefin (TPO) single-ply roofing, usually used on flat or low-slope roofs, is still one of the top-rated cool roofing products. GenTite offers TPO for homes, and Westlake Royal Building Products’ DaVinci roofing provides composite slate and shake roofing as lighter and more affordable alternatives to natural materials.

Not many synthetic materials have been around long enough to know how they’ll perform over time. Still, some show promise, with strong performance ratings and 50-year warranties. Synthetic roofs could be a good choice for those willing to research, but we haven’t included them in our manufactured roofing comparison below.

Roofing Rating Criteria

When reviewing sustainable roofing, we consider a variety of factors, including warranties and certifications.

Longevity

The lifespan of your roof is largely determined by the material you choose. Slate roofing has the longest average lifespan, and wood or 3-tab asphalt shingles have the shortest. However, individual products can be manufactured to higher standards, so a very good asphalt roof may last as long as an average metal one. For our comparison of manufactured roofs, we started with metal roofs ranked highest, followed by tile, then asphalt. Then we modified the manufacturers’ rankings based on warranties.

Energy Efficiency

The radiative properties of roofing materials are solar reflectance and thermal emittance. Both are rated on a scale of 0 to 1, where 1 is the most reflective or emissive. The Cool Roof Rating Council (CRRC) maintains the Rated Products Directory, which is now the primary standard for evaluating roof energy performance since the ENERGY STAR roofing program ended in June 2022.

According to the U.S. Department of Energy, a reflective cool roof can stay more than 50°F cooler than a conventional roof under the same conditions. Cool roofs can reduce cooling energy costs by 7–15% or more, minimize temperature fluctuations inside the home, and reduce the urban heat island effect. In our comparison, we focused on manufacturers whose products are rated by the CRRC and have high solar reflectance values. Keep in mind that even top manufacturers make some products that don’t meet cool roof standards.

You can install solar panels on almost any roof, but we gave higher rankings to manufacturers that offer solar-integrated or solar-compatible roofing systems.

Recycling Practices

All of the roofing materials we considered are technically recyclable. However, in practice, many homeowners have trouble finding local recycling options — particularly for asphalt shingles. When ranking manufacturers, we considered their use of recycled materials, their recycling practices in production facilities, and their circular-economy initiatives.

Federal Tax Incentives

The One Big Beautiful Bill Act, signed July 4, 2025, accelerated the phase-out of the Section 25C Energy Efficient Home Improvement Credit included in the Inflation Reduction Act. The original expiration was the end of 2032, but the new expiration date was December 31, 2025. Homeowners who had qualifying cool roof products installed and operational by December 31, 2025 can still claim the credit on their 2025 tax return.

Comparison Chart

Meet the Manufacturers

Malarkey

The family-founded Malarkey Roofing Products, established in Oregon in 1956 and now a member of Holcim Building Envelope, continues to lead the industry in sustainable shingle innovation. All Malarkey shingles include 3M Smog-Reducing Granules that use photocatalytic technology to convert nitrogen dioxide (NO₂) into water-soluble nitrate salts, actively reducing air pollution. Each average-sized roof has a smog-fighting effect equivalent to planting approximately two trees, according to data from Lawrence Berkeley National Laboratory and 3M.

Malarkey’s proprietary NEX® Polymer Modified (Rubberized) Asphalt incorporates upcycled rubber from tires and post-consumer plastics into the shingle asphalt, diverting waste from landfills while improving durability. Their 2024 Sustainability Report noted cumulative totals of approximately 6.8 million upcycled rubber tires and 4.5 billion upcycled plastic bags diverted from landfills. All three Malarkey manufacturing facilities are GreenCircle Certified for both Recycled Product Content and Waste Diversion from Landfill.

Ludowici

Ludowici has been making clay tiles from locally sourced materials harvested within six miles of the plant, since 1888. They offer a 75-year warranty on standard products, with an expected lifespan of more than a century. Many of Ludowici’s 58 standard colors provide a Solar Reflective Index (SRI) greater than 39, making them an energy-efficient option without limiting design choices.

Although the standard product uses 3% post-industrial recycled materials, the Ludo360 product line uses 40% recycled material from clay scrap, shale, and waste. Ludowici’s manufacturing process generates no waste, and all products are 100% recyclable, either reused as vintage roofing or crushed for construction fill and filter applications.

Interlock Metal Roof Systems

Interlock specializes in aluminum metal roofing systems manufactured in Delta, British Columbia. Their variety of profiles — including slate, cedar shingle, shake, Mediterranean tile, and standing seam — includes solar-compatible bracket systems. The company suggests you’ll “Never Re-Roof Again,” and Interlock backs its products with a Lifetime Limited Warranty that is transferable to a second homeowner as a 50-year non-prorated warranty.

Interlock roofing panels contain up to 95% recycled aluminum and are 100% recyclable at end of life. The proprietary Alunar® Cool Roof Coating System reflects heat to reduce cooling costs by up to 25%. Interlock roofing was selected for the SPOT MODULE Project, which supports the South Pole Overland Traverse in Antarctica.

CertainTeed (Saint-Gobain)

CertainTeed, a subsidiary of Saint-Gobain (the worldwide leader in light and sustainable construction), operates more than 60 manufacturing facilities in North America. The company makes more than 300 residential roofing products, primarily asphalt but also metal roof tiles that resemble clay, slate, and shake. Warranties range from 10 years to lifetime depending on the product.

CertainTeed’s CoolStar granule technology yields CRRC-rated products. They also offer a solar-integrated roofing system. A major recent development is RenuCore™, a patented technology that pelletizes both post-industrial and post-consumer asphalt shingle waste for reuse in hot mix asphalt paving — a meaningful step toward circular economy practices for asphalt roofing. Saint-Gobain’s broader sustainability commitment includes a goal of net-zero carbon emissions by 2050, and a 49% reduction in landfill waste was recently achieved at the Shreveport, Louisiana roofing facility.

Westlake Royal Roofing

In 2021, Westlake Chemical Corporation acquired Boral North America’s building products businesses, and in January 2022, launched the unified Westlake Royal Building Products brand, bringing together the former Boral roofing lines with Royal Building Products and DaVinci Roofscapes. The former Boral brands were rebranded as follows: US Tile (premium clay), Newpoint Concrete Tile Roofing (formerly Boral Concrete), Unified Steel Stone Coated Roofing (formerly Boral Steel), and DaVinci Roofscapes (composite slate and shake). Westlake Royal also offers its own integrated roofing components line including high-performance underlayments like SwiftGuard and the Sol-R-Skin BLUE radiant barrier.

US Tile’s clay products carry a 50-year warranty and contain up to 59% recycled raw materials, and they are 100% recyclable at end of life. Westlake Royal’s clay tiles retain the Cradle to Cradle certification earned under Boral. All clay and concrete tiles carry a Class A fire rating, and select tiles include Class 3 or 4 hail impact ratings. Multiple products are CRRC-rated with cool roof–qualifying color options.

DaVinci Roofscapes composite tiles offer Class A fire, Class 4 impact, and 110 mph wind ratings with a Lifetime Limited Material Warranty, positioning them as a durable alternative to natural slate and cedar shake without the weight or maintenance.

Eagle Roofing Products

Eagle Roofing Products is the concrete tile division of family-owned Burlingame Industries. Concrete tiles do not have the life expectancy of natural clay but are still likely to outlive their 25-year warranty. They match clay’s high solar reflectance values, and when installed with a sheathing ventilation system, can reduce heat transfer into the attic by almost 50% compared to an asphalt shingle roof.

Eagle’s standard tiles contain 2.5% recycled content; their lightweight products are made from 65% recycled material. Eagle has taken environmentally-minded steps in manufacturing, including reducing electricity usage and selecting vegetable- or water-based chemicals. Concrete tiles are heavy, so proximity to manufacturing matters: Eagle’s plants are in Rialto and Stockton, California; Phoenix, Arizona; and Sumterville, Florida.

Berridge

Berridge Manufacturing Company, in business for more than 50 years, specializes in architectural sheet metal products, including roofing, selling directly to architects and contractors. Their watertightness warranty is 20 years (when installed by a Certified Applicator), and the expected lifespan of a Berridge metal roof is 40 to 70 years or more.

The company’s products contain roughly one-third recycled materials and feature advanced Kynar 500® and Hylar 5000® PVDF coatings that resist fading and chalking while reflecting solar radiation, contributing to energy savings and supporting LEED certification goals. Berridge’s 11 manufacturing facilities are concentrated in Texas and the South, though metal sheets are less carbon-intensive to ship than heavier materials like tile.

Tamko

Tamko is a family-owned business and one of the largest roofing manufacturers in America, specializing in asphalt shingle. They offer CRRC-rated products and a limited lifetime warranty on their shingles.

What’s Changed Since 2019

Since this guide was first published, several important changes have affected the world of sustainable roofing:

ENERGY STAR for roofing has been discontinued. The EPA’s ENERGY STAR certification program for roofing products officially ended in June 2022. The CRRC Rated Products Directory is now the standard for evaluating roof product reflectance and emittance. Builders, utilities, and code officials should reference CRRC ratings. The underlying reflectance thresholds (≥0.25 for steep-slope, ≥0.65 for low-slope) still serve as useful benchmarks.

Circular economy gains momentum. The asphalt shingle industry is making real progress on closing the loop. Saint-Gobain/CertainTeed launched RenuCore™, a shingle-to-paving recycling technology. GAF developed its patented RoofCycle™ process, which can use approximately 90% of collected shingle waste to manufacture new shingles, and has committed more than $100 million to scale the technology. Still, with over 13 million tons of shingle waste generated annually and less than 10% recycled, much work remains.

Cool roof science strengthened. Research published in Urban Sustainability found that city-wide adoption of cool roofs could reduce building HVAC energy consumption by 15–35% in current climates and even more dramatically under future warming scenarios, reinforcing the value of reflective roofing choices.
