The particle board we buy is from FSC forest. Because it is manufactured from "Pre-consumer" wood chips, it could be called recyled. Since it is from the fall down of new trees, it is from "NEW" wood that has never been used before. Has USGBC taken a stand on this issue and is it "NEW" FSC wood to be used against MR7 or is recyled to be used for MR4 ?
