The Obtain: Recycling clothes, and fish-friendly hydropower


The information: Lower than 1% of clothes is recycled. A lot of the relaxation finally ends up dumped in a landfill or burned. A workforce of researchers hopes to alter 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 troublesome to separate. To deal with this downside, the workforce 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 power and add a zinc oxide catalyst. 

Why it issues: Whereas related 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. Read the full 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.

For instance her level, she shared grisly photos of fish that had been hit by typical turbine blades. Alternatively, the fish swimming via Natel’s generators appeared comparatively unbothered, curving around the blades and going on their merry way downstream

Not too long ago, our local weather reporter Casey Crownhart had a chat with Schneider about how Natel is working to alter hydropower know-how and juggle local weather motion with freshwater ecosystems to make hydropower a bit extra fish-friendly. Read the full story.
