In a new study, scientists from University of Southampton, University of the West of England Bristol, University of Exeter, University of Cambridge, University of Leeds and University of Bath have developed a way to make smart, electronic textiles that are also sustainable and biodegradable.

The researchers have created ‘Smart, Wearable, and Eco-friendly Electronic Textiles’ (SWEET), technological fabrics with features like sensors or lights that are designed to biodegrade after they reach the end of their lifespan.

“Integrating electrical components into conventional textiles complicates the recycling of the material because it often contains metals, such as silver, that don’t easily biodegrade,” explained Nazmul Karim, lead author of the study and a professor at the Winchester School of Art at University of Southampton. “Our potential ecofriendly approach for selecting sustainable materials and manufacturing overcomes this, enabling the fabric to decompose when it is disposed of.”

To make a biodegradable e-textile, the researchers created a three-layer fabric with a Tencel-fabric base, an interface layer, and the sensor layer. The Tencel is a wood pulp-based fabric, and the team used graphene and a type of conductive polymer known as PEDOT:PSS for the electronic elements.

From there, they were able to use inkjet printing to adhere these materials to the fabric, as this process used less water and energy and produced no material waste, according to the researchers.

The researchers tested the fabric by attaching it to gloves, which five humans wore in the study. The fabric was able to effectively measure the humans’ electrocardiogram (ECG) signals and skin temperature, just like many smart wearables on the market today.

“Achieving reliable, industry-standard monitoring with eco-friendly materials is a significant milestone. It demonstrates that sustainability doesn’t have to come at the cost of functionality, especially in critical applications like healthcare,” Shaila Afroj, a co-author of the study and associate professor of sustainable materials at the University of Exeter, said in a statement.

After testing how the fabric performed in tracking human physiology metrics, the team put SWEET to its bigger test — whether it was biodegradable. The fabric was buried in soil with a 6.5 to 6.8 pH in an incubator with a temperature of around 29 degrees Celsius (84 degrees Fahrenheit) and a relative humidity of around 90%.

After a four-month period, the fabric had a 48% decrease in weight and 98% decrease in strength. The graphene elements also revealed a 40 times smaller impact upon decomposition compared to standard electrodes in wearables. The researchers published their findings in the journal Energy and Environmental Materials.

According to Statista, smart wearable shipments were expected to reach 543 million units worldwide in 2024, and this number is only expected to grow, reaching an estimated 612.5 million units by 2028.

Further, a report by ResearchAndMarkets.com has estimated that the global smart textiles market will increase from $4.85 billion as of 2024 to $29.1 billion by 2033.

With this increasing demand comes the risk of increasing e-waste, or electronic waste. As Earth.org reported, humans currently generate about 50 million to 60 million tons of e-waste per year, and much of this waste does not break down into the soil. Instead, the materials can corrode or react to UV rays and leach harmful substances into the environment. According to the United Nations Institute for Training and Research, e-waste is slated to increase 32% by 2030.

With the growing demand for smart, wearable technology, advancements such as biodegradable electronic textiles will be necessary to meet demand without contributing to more e-waste. The researchers noted that their study can help further additional research into more sustainable, and ultimately fully biodegradable or recyclable, e-textiles and other materials.

“Amid rising pollution from landfill sites, our study helps to address a lack of research in the area of biodegradation of e-textiles,” Karim said. “These materials will become increasingly more important in our lives, particularly in the area of healthcare, so it’s really important we consider how to make them more eco-friendly, both in their manufacturing and disposal.”

Earth911 Inspiration: No Louder Voice?

Published

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.

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.
