Dear Ladies and Gentlemen, I am working on a project about the sustainable use of silicone and am very interested in recyling of silicone. I have two main questions: 1. How much silicone is recycled in the U.S. (or worldwide) annually? 2. Is the recycling process efficient, how much energy does it need? Thank you very much for your help! Sincerely, Ole von Uexkull EPEA Environmental Research, Hamburg, Germany
