A Cambridge startup is betting on plastic crystals to transform refrigeration by replacing gases with solid materials that change temperature under pressure, in a technology still under development and initially aimed at commercial systems. A startup affiliated with the University of Cambridge is working on a refrigeration technology that exchanges gases for solid materials capable […]
Even if they are literally plastics, probably way better* for the environment than the gasses used in refrigeration; and miles better than Freon.
*Assuming it works as efficiently
Also some plastics are made renewably and/or are biodegradable. It’s a broad range of materials.
