Ethanol plants found to emit more toxic air pollutants than oil refineries
Biofuel refineries, touted as a greener alternative to oil, release significant levels of hazardous air pollutants in rural communities across the U.S., surpassing emissions from petroleum refineries.
In short:
- Biofuel refineries release 12.9 million pounds of hazardous pollutants annually, including high levels of carcinogenic chemicals.
- Research reveals biofuel plants are the largest source of acrolein, a toxic chemical causing severe health issues.
- Biofuel facilities often violate air pollution permits, with over 40% failing compliance tests between 2021 and 2024.
Key quote:
“The industry claims biofuels are a better alternative. But what we found is that biofuels are a pretty significant source of hazardous air pollutants.”
— Kira Dunham, a researcher with the Environmental Integrity Project
Why this matters:
Despite being promoted as an environmentally friendly option, biofuel production poses serious health risks due to toxic emissions. Increased regulatory oversight is crucial to address these environmental and public health concerns.

Turning mushroom waste into a resource for sustainable farming
The mushroom industry explores the potential of spent substrate, a byproduct of mushroom cultivation, for various environmental and agricultural applications.
In short:
- Spent substrate, the leftover material from mushroom farming, holds potential for compost, soil decontamination, biofuel, and further mushroom cultivation.
- Small and large mushroom farms alike face the challenge of managing the increasing amounts of spent substrate, seeking innovative solutions for its disposal and reuse.
- The Central Texas Mycological Society has created a community network for free spent substrate pickup, supporting local farms and environmental projects.
Key quote:
"If you're gonna do it, awesome, but account for this waste stream you're producing and how you're gonna get it off of your property."
— Amanda Janney, founder of KM Mushrooms
Why this matters:
Incorporating spent substrate into farming practices supports the principles of circular economy by recycling waste products into valuable resources. This not only reduces waste but also minimizes the environmental impact of farming by decreasing the reliance on synthetic inputs.
The way we eat and grow food has to dramatically change if we're going to feed the world's increasing population by 2050 and protect the planet, according to a major report released in 2019 from the EAT-Lancet Commission.

From pollution to power: Canada's first Indigenous-owned bioenergy facility opens
The Meadow Lake Tribal Council, comprised of nine First Nations, has opened the first 100 percent Indigenous-owned bioenergy facility in Canada. The facility uses wood waste generated from the tribal council's sawmill to generate heat and power.
