New plastic recycling method captures carbon
A closed-loop process for making and recycling polycarbonate plastic also captures carbon to reduce waste and cut emissions.
Turning industrial waste into clean hydrogen fuel
New technique uses waste metal shavings to catalyze hydrogen production, turning nothing but trash and water into clean, renewable fuel.
Fluorine helps make PET plastic waste easier to recycle
Pre-activation of plastics with fluorine-containing molecules disrupts their stability, making them easier to break down and upcycle.
The decline of large river animals and the ecosystems now in peril
The decline of freshwater megafauna, including river dolphins, hippos, and crocodiles, is triggering significant consequences for ecosystems.
Indigenous fire management in Australia traced back 11,000 years
Abandoning traditional practices led to intense dry season fires, drastically altering biodiversity and increasing greenhouse gas emissions.
Cleaning up toxic dyes in wastewater with gold nanoparticles
Gold nanoparticle clusters boosted the efficiency of titanium dioxide in degrading a toxic dye called methyl orange.
Avocado tree waste used to make sustainable food packaging
A material derived from avocado pruning waste and bio-polyethylene combines high strength with biodegradability.
Caffeine coating gives fuel cells a boost
Modifying hydrogen fuel cells with caffeine helped protect them from degradation, resulting in up to 11-fold increase in activity.
