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.

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).

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:

Reduce your reliance on plastics. Especially single-use. Here’s a beginner’s guide to waste reduction.

Advocate for extended producer responsibility (EPR).

Ditch banks that support the fossil fuel industry in favor of green banks.

Support Earth Justice, which sews on behalf of the earth.

Avoid using pesticides and advocate against their use on farms. Support local, pesticide-free farmers whenever possible.

Invest in clean energy and green financing.

Support community-based initiatives impacted most by petrochemical plants, such as Rise St. James and Concerned Citizens of St. John.

Pizza Boxes Are More Recyclable Than Ever

Published

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:

Share the WestRock Grease & Cheese Study with your local recycling coordinator
Point them to the Recycling Partnership’s free toolkit, which includes updated bin labels, mailers, and social media assets
Reference the AF&PA’s industry guidance confirming that paper mills want these boxes back

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.

Energy is required at every step of the food and beverage industry supply chain, from growing grapes to bottling and delivery, making it a significant source of emissions and a prime target for climate innovation. On this episode of Earth911’s Sustainability in Your Ear, we explore how wineries and other producers are turning to clean, renewable energy to cut costs, reduce emissions, and future-proof their operations. We’re joined by James Presta, Business Development Manager at REC Solar, and Mario Trinchero of Trinchero Family Estates, a storied family-run winery in California’s Sonoma County. REC Solar and Trinchero teamed up to bring solar energy to one of the country’s largest winery operations, showing how collaboration between energy experts and agricultural producers can drive meaningful progress toward a carbon-neutral future.

James Presta, Business Development Manager at REC Solar, joined Mario Trinchero of winemaker Trinchero Family Estates on *Sustainability In Your Ear*.

James explains that a decentralized electric grid is emerging—powered by modular solar installations and guided by power purchase agreements (PPAs) that lock in long-term energy prices. When networked together, these individual installations can form a resilient web of renewable power. Solar, wind, and geothermal systems will provide flexibility and stability in a world of climate extremes—if we act quickly enough to scale them. Mario reflects on the motivations behind his family’s move to solar: sustainability is not just good business, it’s essential to preserving the land and legacy that define the brand. By using solar energy in its winemaking process, Trinchero has cut emissions and operating costs while strengthening its commitment to environmental stewardship. We also delve into the mechanics of PPAs—a modern-day version of the 1930s rural electrification initiative that brought power to American farms. But now, companies like REC Solar—not government agencies—extend the grid through private partnerships. These agreements offer fixed pricing, shared risk, and maintenance contracts, but it’s critical to understand the provider’s long-term plans. A strong PPA can unlock the potential to electrify entire supply chains, eliminate dependence on diesel generators, and drive innovations where wires have never reached. And the potential for abundant, clean power is growing. What could we build if we end up with more energy than we need? As James and Mario suggest, the answer may be anything we can imagine with the right infrastructure—without the pollution that defined the last century.

Sustainability In Your Ear: Milwaukee’s Kevin Shafer on Circular Thinking in Wastewater Management

Every gallon of wastewater flowing through a municipal sewer contains recoverable energy, nutrients, and water—assets that the linear “flush and forget” model has long treated as problems to dispose of rather than value to recapture. Meet Kevin Shafer, who has spent more than two decades proving otherwise. As executive director of the Milwaukee Metropolitan Sewerage District (MMSD) since 2002, he’s transformed an agency once mocked as a symbol of government waste into a national model for sustainable infrastructure, and last year, Veolia designated it as America’s first “eco factory.”

Kevin Shafer, Executive Director of the Milwaukee Metropolitan Sewerage District, is our guest on Sustainability In Your Ear.

Milwaukee’s circular approach actually predates the term by nearly a century. In 1926, the district began producing Milorganite—Milwaukee organic nitrogen—a fertilizer made from dried biosolids that most utilities simply spread on fields or incinerate. Today, that product returns $11 to $12 million annually to the city’s budget while keeping waste out of landfills. Kevin explains that this foundational commitment to doing the right thing has shaped MMSD’s culture ever since: ‘We just always look at those type of approaches. It’s foundational to the district.’

The district’s eight digesters at its South Shore plant now generate 80 to 85% of the facility’s electricity from biosolids, with enough material left over to continue making Milorganite. Kevin calls it Cradle to Cradle in action, referring to the philosophy pioneered by architect William McDonough, who visited MMSD in 2006 and was intrigued by work that predated his framework by decades. The district is also partnering with regional breweries and food processors, accepting their organic waste streams for co-digestion. This reduces disposal costs for industry partners while increasing energy production—a synergy that Kevin sees as the future of utility operations.

Looking ahead, Kevin’s 2035 vision targets 100% renewable energy and a 90% carbon reduction compared to 2005. He argues that utilities should see themselves as anchor institutions with generational responsibilities: ‘I won’t be here 50 years from now, but MMSD will be.’ That long view has attracted new partners. ‘All of a sudden they say, oh, here’s someone that’s thinking a little bit differently about something, and maybe we can help them, or they can help us.’ The key barrier to scaling the circular economy, he believes, isn’t technology—it’s institutional culture and a narrow focus on regulatory compliance rather than systems thinking.
