Turning Plastic Grocery Bags into Sustainable Fuel
In Journal of Renewable and Sustainable Energy, by AIP Publishing, researchers from Caltech report using catalytic pyrolysis to turn plastic wastes into a valuable fuel source. They focused on recycling plastic and upgrading plastic into other products or converting it to a vapor with heat, which met a catalyst and turned into the desired fuel-like product.
UCI becomes two-time recipient of STARS Platinum rating for sustainability efforts
For a second time, the University of California, Irvine has achieved a rare platinum rating through the Association for the Advancement of Sustainability in Higher Education’s Sustainability Tracking, Assessment & Rating System, maintaining its status as one of the environmentally outstanding universities in the world.
Research guides future of plastic waste chemical recycling
New research from Cornell University aims to ease the process of chemical recycling – an emerging industry that could turn waste products back into natural resources by physically breaking plastic down into the smaller molecules it was originally produced from.
Researchers Demonstrate Technique for Recycling Nanowires in Electronics
Researchers have demonstrated a low-cost technique for retrieving nanowires from electronic devices that have reached the end of their utility and then using those nanowires in new devices. The work is a step toward more sustainable electronics.
Bio-based coating for wood outperforms traditional synthetic options
Researchers have used lignin, a natural polymer abundant in wood and other plant sources, to create a safe, low-cost and high-performing coating for use in construction. The coating is non-toxic, hydrofobic, it retains wood’s breathability and natural roughness while being resistant to colour changes and abrasion.
University of Portsmouth becomes the first non-US partner of a new project to tackle plastic pollution in the USA
The University of Portsmouth is now a key member of a collaborative effort funded by the United States Department of Energy (DOE) and industry to tackle the growing global crisis of plastic waste.
Turning Plastic into Foam to Combat Pollution
In Physics of Fluids, researchers have developed a method to turn biodegradable plastic knives, spoons, and forks into a foam that can be used as insulation in walls or in flotation devices. The investigators placed the cutlery into a chamber filled with carbon dioxide. As pressure increased, the gas dissolved into the plastic. When they suddenly released the pressure in the chamber, the carbon dioxide expanded within the plastic, creating foaming.

Battery parts can be recycled without crushing or melting
Researchers at Aalto University have discovered that electrodes in lithium batteries containing cobalt can be reused as is after being newly saturated with lithium. In comparison to traditional recycling, which typically extracts metals from crushed batteries by melting or dissolving them, the new process saves valuable raw materials, and likely also energy.
The Future Looks Bright for Infinitely Recyclable Plastic
Plastics are ubiquitous, but they’re not practical. Less than 10% are recycled, and the other ~8 billion tons are creating a pollution crisis. A Berkeley Lab team is determined to change that. A new analysis shows producing and recycling their game-changing new plastic could be easy and cheap enough to leave old plastics in the dust.
Is battery recycling environmentally friendly?
In a new study, researchers at Aalto University have investigated the environmental effects of a hydrometallurgical recycling process for electric car batteries. The carbon footprint of the raw material obtained by the recycling process studied is 38% smaller than that of the virgin raw material. The difference is even greater if copper and aluminium recovered during mechanical pre-treatment are included.
