The information: Lower than 1% of clothes is recycled. A lot of the relaxation finally ends up dumped in a landfill or burned. A staff of researchers hopes to vary that with a brand new course of that breaks down mixed-fiber clothes into reusable, recyclable components with none sorting or separation upfront.
How they did it: Many clothes are fabricated from a mixture of pure and artificial fibers. As soon as these fibers are mixed, they’re tough to separate. To sort out this downside, the staff used a solvent that breaks the chemical bonds in polyester cloth whereas leaving cotton and nylon intact. To hurry up the method, they energy it with microwave vitality and add a zinc oxide catalyst.Â
Why it issues: Whereas comparable strategies have been used to recycle pre-sorted plastic, that is the primary time they’ve been used to recycle mixed-fiber textiles with none sorting required. Learn the complete story.

What new hydropower tech says about local weather motion
Again at MIT Know-how Evaluate’s ClimateTech occasion in 2022, Gia Schneider, a cofounder of Natel Power, spoke about her firm’s mission to design hydropower generators which are safer for fish.
As an example her level, she shared grisly pictures of fish that had been hit by standard turbine blades. However, the fish swimming by Natel’s generators appeared comparatively unbothered, curving across the blades and occurring their merry method downstream.Â
Lately, our local weather reporter Casey Crownhart had a chat with Schneider about how Natel is working to vary hydropower expertise and juggle local weather motion with freshwater ecosystems to make hydropower a bit extra fish-friendly. Learn the complete story.
