I have yet to find a comprehensive list of manufacturers offering take back programs and supporting documentation of their recycling rates, as required by GBCI. The Better Materials database only has a yes or no for this, and no link to the program itself. No resources are available from USGBC. So far it seems like the only products that fit the bill are in carpet and flooring. Or maybe there is some secret database of these programs that I don't seem to be able to find?
