You’ve probably heard of silicone before: It’s in houseware, sealants, and medical devices. Think silicone baking molds, silicone utensil sets, etc.

But what exactly is it? And is silicone plastic? Not exactly.

Is Silicone Plastic? Here’s What You Need to Know

First, it’s important to note silicone is a synthetic material, made from a combination of silica (sand) and oxygen (more on this later). The silicone-making process is complex and energy intensive, which contributes to emissions.

Silicone’s environmental footprint is worth discussing because it relies on non-renewable hydrocarbons for production and has challenges in recycling and biodegradability.

However, in terms of how silicone compares to plastic on an environmental impact scale, it is a better substitute. Here’s everything you need to know about silicone and if you should use it.

how is silicone made?

Silicone is made by extracting silicon from silica and passing it through hydrocarbons. It’s then mixed with other chemicals to create silicone.

However, to fully understand this process, it’s important to get the terminology right. Here’s a step-by-step break down:

silica

Silica is the raw material used to make silicone resins, aka sand. Beach sand is practically pure silica, as is quartz.

silicon

This is the base element that makes up silica, but silicon is not generally found in nature in this elemental form. It is made by heating silica at very high temperatures with carbon in an industrial furnace.

silicone

The silicon is then reacted with fossil fuel–derived hydrocarbons to create the siloxane monomers (alternating silicon + oxygen atoms) which are bonded together into polymers to form the backbone of the final silicone resin.

Is Silicone Plastic? Here’s What You Need to Know

is silicone the same as plastic?

Silicone is not the same as plastic, but it is similar. Technically, silicone could be considered part of the rubber family.

However, silicone is something of a hybrid between a synthetic rubber and a synthetic plastic polymer. Silicone can be used to make malleable rubber-like items, hard resins, and spreadable fluids.

In a similar way to plastic, it can be shaped or formed and softened or hardened into practically anything.

However, here are its distinct differences from plastic:

  • More temperature resistant and durable  
  • Has a low reactivity with chemicals
  • Highly gas permeable, making it useful for medical or industrial applications
  • Easy-to-clean, non-stick, and non-staining

is silicone recyclable?

Silicone shares another trait with plastic: It’s hard to recycle.

Silicone has a low recycling rate. This is because most silicone is not recyclable through your local municipal recycling program (though you should always double check). While silicone is technically recyclable, you would likely have to take it to a specialized private recycling facility. 

Even then, silicone would likely be downcycled into oil used as lubricant for industrial machines. Like plastic, it can never be the same thing twice.

However, it’s worth noting there are some brands, like Stasher bag, that utilize silicone and have a recycling program in place.

Is Silicone Plastic? Here’s What You Need to Know

does silicone give off microplastics?

Though silicone is technically a plastic polymer, its durable molecular structure keeps it from shedding microplastics in the way that common plastics do.

That said, silicone can still break apart into small pieces and enter our waterways.

To make it last as long as possible, be mindful of using it around sharp objects, like the blades of a food processor or sharp knife.

is silicone environmentally friendly?

Silicone isn’t the most environmentally friendly material to choose from, but it’s better than plastic. Just be mindful that producing silicone uses hydrocarbons derived from petroleum, which is a fossil fuel and non-renewable resource.

However, unlike plastic, silicone items don’t tend to be made into single-use items. For example, silicone baking sheets, molds, and utensils can be reused for years.

Stasher bags are a great example of this: One Stasher bag keeps 260 single-use plastic bags out of oceans per year. Plus, they’re durable, easy to use, and safe for the dishwasher, microwave, and oven (up to 425°F).

Here are some ways to lessen silicone’s environmental impact:

  • Buy secondhand silicone items at local thrift stores, or Facebook marketplace
  • Only get it if you plan to use it for years to come
  • Only wash it when you need to, and when you do, use the dishwasher to save energy and water
  • Look for high quality, food grade or medical grade silicone that does not contain any fillers
  • Find a new home for gently used silicone, if you’re ready to get rid of yours

is silicone safer than plastic for food?

Silicone is a safer alternative to house food than plastic, as long as it’s food-grade silicone. I personally love using Stasher bags (which are made from food-grade silicone) to pop my popcorn in the microwave!

However, it’s important to note silicone is not completely chemically unreactive and can potentially release toxic chemicals over time.  

Here’s some research that’s been conducted on silicone:

  • One study tested the release of siloxanes from silicone nipples and bakeware into milk, baby formula and a simulant solution of water and alcohol. After 72 hours in the alcohol solution, several siloxanes were detected.  
  • Another study found siloxanes being released from silicone bakeware, with leaching increasing as the food fat content increased (such as using oils). 
  • The effects of common siloxanes shown in animal studies could lead to impaired fertility and potential carcinogenicity.

However, this doesn’t mean you have to toss out all your silicone items right now: Not enough research has been done to fully understand the health effects of using silicone.

That said, you may want to bake in something other than silicone if you have the option.

Though it is worth noting silicone cookware is likely safer than traditional non-stick varieties using Teflon coatings. If it’s a choice between the two, use silicone. Glass, ceramic, and stainless steel bakeware are best.

Silicone items like spatulas, pot holders, etc. appear safe given the small amount of contact they make with food. Just don’t melt them! Wooden cooking utensils are also another alternative.

Natural rubber can be a good alternative for things like bottle nipples and soothers, if there is no risk of rubber allergy. More silicone alternatives are listed below.

Is Silicone Plastic? Here’s What You Need to Know

alternatives to silicone

If you’d prefer not to use silicone, here are some sustainable silicone alternatives to consider. But remember: Using what you have will always be the most eco conscious choice, so only purchase new items if you really need them or can’t find them secondhand.

beeswax wraps

Instead of silicone lids for your bowls, try beeswax wraps. These are compostable at the end of their life. You just use the warmth of your hands to secure them into place.

unbleached parchment paper

You can use these to line baking sheets. I recommend If You Care’s parchment paper, as it’s fully compostable at the end of its life.

jars

Use upcycled glass jars to store leftovers, or even freeze food in. These also make great containers for on the go snacks or lunches.

plates

Place leftovers in a bowl and cover it with a plate. This is one of my favorites because it’s so simple!

wooden utensils

Opt for wooden cooking utensils where you can, like wooden spoons, ladles, spatulas, slotted spoons, and rice scoops.

glass storage containers

Try choosing glass snapware to store leftovers in. You can also freeze food in these, as well as heat up food in the microwave (just remove the lid first).

kitchen towels

Instead of potholders that often contain silicone, you could try using cotton kitchen towels – when folded they are heat resistant and multipurpose. Professional cooks prefer them!

So, is silicone plastic? Not quite, but it is a synthetic material.

What are your thoughts? Do you keep silicone products in your kitchen? Let me know in the comments!

Using Reclaimed Materials in Your Home & Yard

Published

on

When most of us think of landfills, we think of rotting disposable diapers, apple cores, and old clothing. Our thoughts don’t usually turn to discarded construction materials. However, the U.S. generated 600 million tons of construction and demolition waste in 2018, according to the U.S. Environmental Protection Agency. That’s more than double the amount of municipal solid waste generated annually.

A lot of wood, concrete, bricks, glass, asphalt, and plastic are going to landfills instead of being recycled or reused. This creates a massive opportunity for improvement. Repurposing materials is a great way to reduce the ecological impact of a project. Demolition waste can be artfully repurposed in home remodeling, construction, and landscaping projects, adding beauty and charm. Reclaiming waste also helps you save money, as many people go into debt when constructing and remodeling homes.

Here are some easy strategies to help you get started.

Plan Ahead

Reclaiming materials typically takes more time than just buying new items. And it requires more planning.

It is challenging to take a cookie-cutter approach to salvaged materials. When constructing or remodeling your home, you may need to customize it to the available materials. One method is to analyze what materials are available and then plan your project design accordingly. The opposite approach is to design your project and then collect the needed reclaimed materials. When taking the latter approach, it is helpful to rely on salvaged materials that are more commonly available.

Regardless, planning ahead and having plenty of storage space is helpful.

Check Whether Your City Requires Deconstruction

A growing number of cities now require that old houses be taken apart by hand rather than knocked down, which puts far more salvaged material into circulation. Portland, Oregon, passed the first such ordinance in 2016. Today it requires deconstruction of any house or duplex built in 1940 or earlier, and the work must be done by a certified deconstruction contractor who documents every salvaged board.

San Antonio has gone furthest. Under the third phase of its ordinance, which took effect January 1, 2025, mechanical demolition is off the table for any single-family home, multi-unit building, or accessory structure built in or before 1945 anywhere in the city, and in or before 1960 in protected areas. City officials report that contractors recover about 70% of a building’s weight, with more than half of that going to reuse rather than recycling.

More than half a dozen cities from Pittsburgh to Boulder have adopted their own versions, and the ReBuilding Center and other reuse nonprofits are pushing for mandatory salvage minimums to make the rules bite. For anyone hunting materials, the practical upshot is simple: if your city has an ordinance, more old-growth lumber, doors, trim, and fixtures are moving through local salvage yards than used to.

Find Good Sources of Salvaged Materials

One of the easiest ways to find free materials and to prevent them from going to landfills is to visit demolition sites. This can be a great source of windows, doors, woodwork, fixtures, and even appliances. Construction sites can be excellent sources of surplus or slightly damaged materials and supplies. Construction dumpsters are often packed with useful materials.

It is essential to speak with the foreman to get permission before taking any materials. If you are seeking something specific, ask the contractors working on-site if they have found that window or door you want. They might be willing to set materials aside for you. But again, ask for permission first.

Antique malls, architectural salvage stores, and home improvement donation centers are good sources of anything from windows and doors to hardware, tile, and plumbing fixtures.

The Habitat for Humanity ReStore network is another valuable source of new and used building materials, and the proceeds benefit a good cause. Build Reuse, the national nonprofit for building material reuse, maintains a membership directory that will point you to salvage stores and deconstruction contractors in your region. ReuseWood.org, a directory built by the American Wood Council and Canadian Wood Council with Build Reuse, lets you search by ZIP code for barn wood, timbers, millwork, flooring, and reclaimed doors and windows.

Peer-to-peer platforms have become the fastest way to find one-off pieces. Craigslist, Freecycle, Facebook Marketplace, Nextdoor, OfferUp, and local Buy Nothing Project groups all turn up leftover tile, cabinets, pavers, and lumber from neighbors’ finished projects. Setting up saved searches and alerts beats checking in occasionally, since good material moves within hours.

Some people even purchase properties with reclaiming the materials in mind. For example, old barns are filled with gorgeous weathered lumber that can be deconstructed and repurposed.

Utilize Repurposed Materials

Beautify your home with reclaimed and repurposed wood beams and ceramic tiles.

Use cleaned-up bricks recovered from construction debris to create patios, pizza ovens, and pathways, and other attractive features for your new home.

Repurpose shipping containers to make storage sheds. Or stack them to make multi-tiered structures, like a guest room.

Use crushed concrete as aggregate for walkways and driveways.

Sinks, vanities, bathtubs, cabinets, shower stalls, light fixtures, and even toilets can be repurposed.

Find Supplies with Recycled Materials

There are also some construction materials available on the market made from recycled materials.

Plastic bottles are recycled to make composite lumber or bricks, and recycled glass is made into tile and countertops. Old newspapers or blue jeans are made into insulation products, and cork bottle stoppers can make flooring and panels. Purchasing these materials might not be as economical but it does conserve resources.

Using salvaged materials in construction and renovation projects adds character and is a great way to reduce waste. And having an eye for reuse helps conserve precious resources and protect the environment.

Best of Earth911 Podcast: ePlant CEO Graham Hine Listens to the Trees

Published

on

Smart homes are commonplace today. Now, the intelligent yard is poised to join the mix. Meet Graham Hine, CEO of ePlant, which recently introduced the TreeTag. This solar-powered monitor is attached to a tree to monitor its health and send updates wirelessly to a phone. TreeTags are placed onto the side of trees using a screw and measure minor size fluctuations in trees. For example, the bark’s contraction can indicate stress, such as a lack of water. The TreeTag includes an accelerometer to detect movement patterns that may suggest instability and a humidity sensor to augment local weather data. The TreeTag employs artificial intelligence to process and transmit its data to the cloud. You can talk to your tree using ChatGPT as an interpreter. The experience is like chatting with a friend, but it might be about how much water the tree needs to be healthy or a report on its growth and the carbon it has captured as it grows.

Graham Hine, cofounder and CEO of ePlant, is our guest on Sustainability In Your Ear.

ePlant is among the most intriguing and fun devices we’ve seen this year. Technology can help us see the environment in new ways, bolstering our senses with data that lets us identify biases so that we can respond to climate change, local extreme weather, and drought thoughtfully and efficiently. Solar-powered devices like TreeTag, if manufactured with minimal environmental impact, can expand our sensory engagement with the health of forests, orchards, and suburban yards to reduce overwatering, preserve tree and plant species struggling with local weather changes, and potentially increase the yield of food produced per gallon of water used. You can learn more about ePlant at https://www.eplant.com/

UPDATE: ePlant has since pushed TreeTag well past the smart-yard use case that framed this conversation. In May 2025, TreeTags supplied the live physiological and environmental data behind the Avanade Intelligent Garden at the RHS Chelsea Flower Show; sensors on 12 trees fed an app that let visitors ask the trees how they were doing, and the garden took a gold medal. The company also offers precision irrigation for growers using TreeTag as a LoRaWAN dendrometer that can serve a single vineyard block to thousands of acres.

Need to Recycle Your Satellite TV Dish? Read This First

Published

on

Satellite dishes outlast the subscriptions that put them there. Drive through almost any American neighborhood and you will see them still bolted to fascia boards and chimney straps, aimed at satellites their owners stopped paying for years ago.

The subscriber base that installed those dishes is collapsing. Pew Research Center found in July 2025 that 36% of U.S. adults still subscribe to cable or satellite TV, while 83% watch streaming services. DIRECTV and DISH told investors in 2024 that they had collectively lost 63% of their satellite subscribers since 2016.

Every one of those canceled accounts left hardware behind, and removal and recycling still fall to the subscriber, who gets little support from the provider. For lack of clear information, a lot of that hardware ends up in a landfill.

Can You Recycle Your Satellite TV Dish?

Depending on who you ask, the proper method of disposal for a satellite TV dish can be as clear as, well, a fuzzy TV signal. So let’s tune in to what a dish system is made of, because the answer determines where each piece goes.

A residential satellite system is not one product. It is four material streams bolted together:

  • The reflector. The curved part everyone pictures. On modern 18- to 20-inch DIRECTV and DISH installations it is thin, powder-coated steel. Older and larger dishes are often aluminum. Either way, it is scrap metal and easily recyclable in most communities.
  • The LNB. The low-noise block downconverter on the end of the arm. It holds a circuit board and is the piece that makes the system electronic waste.
  • The mount and hardware. Usually galvanized steel, and usually the heaviest recyclable component in the assembly.
  • Coaxial cable. Copper conductor inside plastic jacketing, which scrap yards buy separately as insulated wire.

The Institute for Environmental Research and Education recommends separating those parts of the dish before you haul anything anywhere: detach the LNB, coil the coax, and sort aluminum from steel. That takes about 20 minutes with a screwdriver and a wrench, and it is the difference between a recycler accepting your load and turning it away.

The receiver, DVR, and remotes are a separate question, and an important one. Those are usually leased. If you cancel service and keep them, you will be billed for them.

Once It’s Installed, It’s Yours

This is the part that surprises people. The dish becomes the property of the homeowner at installation. Neither provider sends a technician to take it down when you cancel, and neither is obligated to. DIRECTV’s own support forums state the position plainly: the receivers go back, the dish stays, and what happens to it next is up to you.

Renters have a related wrinkle. The FCC’s Over-the-Air Reception Devices rule protects your right to install a dish under one meter in areas under your exclusive control, such as a balcony or patio, and it limits what landlords and HOAs can prohibit. It does not cover shared roofs or exterior walls, and it does not remove your responsibility to take the dish down and repair the mounting holes when you move out.

Read your lease before you install anything.

The Rules Changed in Some States, But Not Federally

U.S. federal guidelines still do not regulate circuit boards as hazardous waste, and there is no national electronics recycling law. What exists instead is a patchwork of state and local policy.

Twenty-five states plus the District of Columbia have passed electronics recycling legislation, most of it built on producer responsibility principles, and roughly two dozen states ban electronics from landfills outright. Whether your dish system is legally landfill-bound depends entirely on your ZIP code.

One change is worth flagging because it is new and relevant. Oregon’s modernized E-Cycles program took effect January 1, 2026, and the expanded list of covered devices now includes cable and satellite receivers, routers, modems, and game consoles. Oregon residents can drop those off free. The reflector itself is not a covered device, so it still goes to scrap metal, but the electronic half of the system finally has a no-cost home in one more state.

The stakes behind these rules keep climbing. The UN’s Global E-waste Monitor 2024 found the world generated a record 62 million metric tons of electronic waste in 2022 and formally collected and recycled just 22.3% of it. Generation is on track to hit 82 million metric tons by 2030, growing about five times faster than documented recycling.

Don’t Count on the Scrap Value

Earlier versions of this article suggested that local scrap vendors might be willing to pull the system down for the value of the materials. That is worth a reality check in 2026.

Scrap yards pay by weight and by grade. A modern 18-inch dish is a few pounds of thin, coated steel, which grades low and weighs almost nothing. The coax and the mount are worth more than the reflector, and the whole assembly is still unlikely to buy you lunch. Older six- to 12-foot aluminum C-band dishes are a genuinely different story and can be worth hauling. For the small dishes on most roofs, treat scrap as a disposal route rather than a payday, and do not expect a yard to send a crew for it.

Tips To Get You Started

Here at Earth911, we want your satellite TV dish handled properly at the end of its life. That is not the case. Here is the sequence that actually works:

  • Check your provider’s recycling page first and know what it covers. DIRECTV’s recycling page issues a prepaid shipping label and routes equipment to R2-certified recyclers. DISH points customers to Best Buy and a UPS mail-in program that offers free recycling if you pay the shipping costs. Both programs are built around receivers, remotes, and small equipment. Neither is designed to take the dish off your roof.
  • Return leased equipment on time. Providers typically give you about three weeks from the disconnect date before non-return fees land on your final bill. Get a receipt at the drop-off point and keep it.
  • Search for a satellite dish removal service, a handyman, or a local roofing company. Roofers are the right call if the mount is through the shingles, because someone has to seal the penetrations afterward. Removal is a roof job, not a recycling job, and the two rarely come bundled.
  • Find a certified recycler for the electronics. Look for R2 or e-Stewards certification, which tells you the downstream processing is audited. Use the Earth911 recycling search to find electronics and scrap metal locations near you.
  • Take the reflector and mount to a scrap metal yard. Separate steel from aluminum before you go.
  • Consider reuse before recycling. A working dish and LNB have a second life in free-to-air reception, RV and off-grid setups, and amateur satellite work. Offer it to others locally before you scrap it. There are also plenty of repurposing projects if you would rather keep it out of the waste stream entirely.
  • Watch out for lead-generation sites. Several “satellite dish removal” domains are referral networks that sell your contact information to whichever contractor is paying, not recyclers. Ask any service directly where the material goes and whether they are certified.

Earth911 Does Not Remove or Recycle Dishes

We regularly receive inquiries about whether Earth911 offers removal services. We do not. Earth911 does not offer satellite TV dish removal or recycling. If a satellite TV provider or one of its representatives tells you otherwise, that is not accurate information.

What Comes Next for Satellite TV

The retirement wave is not finished. DIRECTV shed roughly 288,000 subscribers in the third quarter of 2025 alone, according to reporting by TheStreet. EchoStar reported 6.63 million pay-TV subscribers at the end of the first quarter of 2026 after a net loss of 366,000 in three months, and its Dish DBS unit filed a prepackaged Chapter 11 restructuring on June 30, 2026. The company says Dish Network and Sling TV service continues without interruption.

For subscribers, the practical takeaway is unchanged: corporate restructuring does not come with a dish removal crew. If you are canceling, plan for the disposing of the hardware. Return what is leased, get the dish down safely, split the metal from the electronics, and route each stream to somewhere that will process it. That is a Saturday afternoon’s work that can keep your dish out of a landfill.
