Have you heard of polyurethanes? As you read this, you’re undoubtedly close to some, or maybe sitting on them: this versatile class of chemicals is used for everything from padding your couch to insulating your windows, packaging food to carpet underlay, electronics casings to skateboard wheels. They also have vital uses in space, triggering a new ESA Clean Space project aiming to manufacture them in a greener way.
