What we call waste is really just misallocated feedstock—raw materials waiting to be cycled back into the next generation of products and packaging. According to research by the World Economic Forum and United Nations Development Programme, the circular economy could unlock $4.5 trillion in new global value by 2030, and investors are racing to capture part of that opportunity. Meet Elizabeth Blankenship-Singh, Director of Innovation at Overlay Capital, an Atlanta-based alternative investment firm whose Waste and Materials Fund is backing both early-stage materials innovators and later-stage recycling operations with established infrastructure. Overlay’s strategy involves investing in innovation and implementation simultaneously—in both startups and established companies—to accelerate progress across multiple layers of the circular economy. It offers a window into where smart money sees the materials transition heading.
Elizabeth Blankenship-Singh, Director of Innovation at Overlay Capital, is our guest on Sustainability In Your Ear.
Elizabeth explains that sortation is the biggest bottleneck at the materials recycling facilities (MRFs) your garbage and recycling are sent to after curbside collection. The U.S. is simultaneously the world’s leading exporter of scrap aluminum and the number one importer of finished aluminum, because we’ve lacked domestic sorting capacity. Overlay has invested in companies like AMP Robotics, which recently closed a 20-year contract with SPSA, a southeastern Virginia municipal authority, to sort all recyclables from four to five cities using AI-driven systems. When you fix sortation, she says, you trigger a domino effect: recycling rates climb, landfill life extends, and margins improve as higher-purity materials command premium prices.
Overlay’s portfolio also includes next-generation materials companies united by a common thesis: they must be better, faster, cheaper, and more sustainable than what they replace. Cruz Foam converts chitin from shrimp shells into compostable packaging foam. Simplifyber uses cellulose to create biodegradable soft goods through 3D molding, bypassing traditional textile manufacturing entirely. Terra CO2 just closed a $124 million Series B to scale low-carbon cement technology that could cut into concrete’s 8% share of annual global CO2 emissions. Each uses abundant, waste-derived feedstocks and has achieved or is on a clear path to price parity with incumbents.

Earth911 Inspiration: No Louder Voice?

Published

on

Saint Augustine, in a sermon to his congregation, urged them to look beyond books, even to Bible, to see God in nature: “God, whom you want to discover, never wrote a book in ink. Instead, He set before your eyes the things that He had made. Can you ask for a louder voice than that?”

How do we move past the identity politics that dominate discourse on the left and right at this fractured moment and amount to a cacophony of special pleadings for the advantage of small groups, nations, and isolated networks? That’s why we ignore the Earth, because we cannot look up from our daily concerns. We need a new universal value that unites, one that emphasizes human dignity in the context of a restored, regenerating nature.

Earth911 inspirations. Print them, post them, share your desire to help people think of the planet first, every day.

Petrochemicals: How They Affect People + Planet

Published

on

Last Updated on February 6, 2026

Have you ever heard of Cancer Alley? It’s an ~85-mile stretch along the banks of the Mississippi River where communities exist beside ~200 fossil fuel and petrochemical operations.

Residents of Cancer Alley are exposed to more than 10x the level of health risk from hazardous air pollutants than people living elsewhere in the state. And it’s worth mentioning the residents exposed are mostly BIPOC and low-income communities.

Petrochemicals: How They Affect People + Planet

But what exactly are petrochemicals? And how exactly do they harm both people and planet? Here’s everything you need to know.

what are petrochemical plants?

Petrochemical plants are facilities that process crude oil and fracked gas to make plastics, industrial chemicals and pesticides. They are usually located near petroleum refineries or integrated into large petrochemical complexes.

Petrochemical factories process and transform hydrocarbons into chemical products used in the plastics, textiles, automotive, pharmaceutical, and electronic industries.

Obtaining the raw materials needed to make petrochemicals is already carbon intensive – and the raw material processing these plants do only pollute further.

what is an example of a petrochemical?

An example of a petrochemical is ethylene, which is the most widespread petrochemical in the world, primarily used in the plastic industry to make polyethylene. You may know polyethylene as plastic resin #2 (HDPE – high density – used for milk jugs, detergent bottles, etc.) and #4 (LDPE – low density – used for plastic grocery bags/film).

Olefins plants (a specific type of petrochemical plant) produces ethylene. These plants use steam crackers and the energy input is considered one of the most energy intensive processes in the chemical industry.

But olefin plants are only one type of petrochemical plant. Aromatic plants produce nezene, toluene, and xylene from naphtha and other refinery streams. These make up dyes, detergents, and plastic products.

Syngas plants use natural gas or coal to generate synthetic gas, which creates industrial chemicals such as ammonia and methanol.

Petrochemicals: How They Affect People + Planet

are petrochemicals harmful?

Petrochemicals have been linked to health problems, including cancer, according to an analysis in the New England Journal of Medicine.

That’s because to make petrochemicals, plants release volatile organic compounds (VOCs) that pollute the air. Not to mention refineries and plants discharge toxins into waterways, which contributes to water pollution.

According to an Environmental Integrity Project (EIP) report, nearly 70 petrochemical companies across the nation are sending millions of pounds of pollutants into waterways each year due to weak or nonexistent regulations. And yes, it does contaminate drinking water.

Residents of Cancer Alley have experienced this firsthand. Polyfluoroalkyl substances (PFAS) are present in their drinking water at levels hundreds of times higher than currently-suggested safe levels for human consumption.

And residents suffer the effects of extreme air pollution on a daily basis. Including increased risks of infertility, respiratory illness and cancer.

According to 70 interviews conducted by Human Rights Watch, women in Cancer Alley reported miscarriages, high-risk pregnancies, and poor health of newborns. Many shared stories of entire communities decimated by cancer (hence the name).

Petrochemicals: How They Affect People + Planet

do petrochemicals harm the environment?

Yes, petrochemicals harm the environment too – petrochemical plants use massive amounts of energy to function, and in doing so, pollute the air, water and soil. Everything is intersectional.

Plus, as we transition away from fossil fuels to power our homes and businesses, petrochemical plants are becoming a lifeline to Big Oil. That’s because crude oil and gas are used to make many petrochemicals.

If petrochemical plants are allowed to grow, unregulated, there will be more consumption of oil and gas to come for decades. This directly contributes to climate change.

what is being done + how can we help?

Cancer Alley residents are fighting for reignition and change.

Sharon Lavigne, a retired special education teacher, founded Rise St. James, an organization focused on bringing environmental justice to the people of St. James Parish. The parish is located in one of Cancer Alley’s polluted hotspots, and Lavigne’s demands are far from radical. She simply wants clean air and drinking water.

Yet a lawsuit filed by the Biden Justice Department and EPA was recently dropped by the current administration.

Robert Taylor, founder of Concerned Citizens of St. John, said “…our government has abandoned us. We have been designated a sacrifice zone.”

Unfortunately, Texas recently also cleared the way for petrochemical expansion despite health warnings.

So how do we make an impact? Here are a few ways we can help:

  • Ditch banks that support the fossil fuel industry in favor of green banks.
  • Avoid using pesticides and advocate against their use on farms. Support local, pesticide-free farmers whenever possible.
  • Speak up and spread the word. Share this article so more people know about petrochemicals and why they harm people + planet.

How are you advocating against petrochemicals? Let me know in the comments!

Pizza Boxes Are More Recyclable Than Ever

Published

on

Back in 2020, the Recycling Partnership and WestRock released a scientific study demonstrating that used pizza boxes are recyclable, even when greasy and contaminated with cheese. Since that research was published, the findings have driven significant improvements in recycling program acceptance nationwide.

The basic results are clearly favorable for greater acceptance of pizza boxes for recycling. The typical pizza box has 1% to 2% grease content by weight, which is about one-tenth the acceptable level for cardboard (corrugated paperboard) recycling. The study looked at the impact of greasy boxes on mixed recycling loads that include 8% greasy pizza boxes with varying levels of greasy contamination from between 3% and 40%. The recycled materials produced were still viable for packaging use, well within the tensile strength required for packaging.

Recycling Acceptance Has Expanded

Since the study was released, pizza box recycling acceptance has grown substantially. According to the American Forest & Paper Association (AF&PA), 82% of Americans now have access to a community recycling program that accepts pizza boxes—up from 73% in 2020. AF&PA member company mills representing 94% of old corrugated container consumption now accept pizza boxes with no observed impacts to operations or finished product quality.

The AF&PA’s guidance is unambiguous: “Corrugated pizza boxes are successfully recycled every day at paper mills throughout the country. Our industry wants these boxes back to recycle.”

Since about 3 billion pizza boxes are used in the U.S. each year, the improved recycling processes can capture roughly 600,000 tons of cardboard annually that could be turned into new boxes, paper towels, toilet paper, and other paper products.

What To Do Do With Your Next Pizza Box?

Our guidance is based on the research and current program acceptance:

For most Americans: Your recycling program likely accepts pizza boxes. Remove any leftover pizza, flatten the box, and place it in your recycling bin. Light grease stains are acceptable; the science confirms they don’t affect the recycling process.

If your box has a waxed paper liner, remove it before recycling: The box itself can be recycled as normal cardboard.

If your program prohibits pizza boxes: Don’t send materials your program won’t accept. Instead, check the composting options below or contact your local recycling coordinator to share the Recycling Partnership’s toolkit and AF&PA research. Citizen requests carry a lot of weight at local departments of sanitation.

If your box is heavily saturated with grease: Consider composting instead of recycling. While typical grease levels are fine for recycling, boxes that are completely soaked may be better suited for composting programs.

The Recycling Partnership tested a variety of grease- and cheese-contaminated pizza boxes. Only the box on the right approached unacceptable recycling results.

What About The Cheese?

You might ask, “Isn’t cheese a barrier to successful recycling?” Cheese tends to solidify and get screened out during the pulping process,” according to the 2020 report. The researchers tested sending boxes heavily contaminated with cheese through a recycling process and found that it did not significantly reduce the resulting paper fiber’s viability for reuse. Paper mills have become increasingly adept at screening out chunks of cheese during processing.

Composting: A Great Alternative

When recycling isn’t available, or your pizza box is heavily soiled, composting provides an excellent alternative that keeps cardboard out of landfills while creating nutrient-rich soil. Many cities now accept pizza boxes in curbside organics programs:

New York City requires all residents to separate food scraps and food-soiled paper from trash as of April 2025. Pizza boxes are explicitly accepted in the brown bin program.

California jurisdictions statewide must provide organics collection under SB 1383. Food-soiled pizza boxes can go in compostables carts.

Portland, Oregon updated its guidelines under the state’s Recycling Modernization Act. As of July 2025, empty pizza boxes with minimal grease are recyclable, while greasier boxes can go in yard waste bins.

King County, Washington accepts pizza boxes in composting, noting that food-soiled paper can be composted, though clean cardboard is better recycled.

For home composting, tear greasy cardboard into small pieces to speed up decomposition. The cardboard provides essential carbon to balance nitrogen-rich food scraps, improving compost quality.

How to Check Your Local Guidelines

Domino’s partnered with WestRock to launch Recycle My Pizza Box, which lets you enter your ZIP code to find specific recycling guidance for your area. The site also provides template language you can share with local recycling programs that haven’t yet updated their guidelines.

Advocate for Change

If your municipality still lists pizza boxes in the “no” pile, you can help drive change:

The progress since 2020 shows that advocacy works. Communities from Anchorage to New York have updated their programs based on this research.

Eat happily—that box can become the next pizza box you receive, or any number of other paper products that keep valuable fiber in circulation.
