Headline: Researchers discover smarter way to recycle polyurethane

■ Release Date: 2024.8.16

■ Published by: Aarhus University

■ Keywords: polyurethane, recycle, succinic acid

■ Abstract:

Researchers have found a better method to recycle polyurethane foam from items like mattresses: They are not only able to break down PUR and separate the two main components -- they can do it in one go. This is great news for the budding industry that aims to chemically recover the original components of the material -- making their products cheaper and better.
