Our project is located in Los Angeles, California. Construction waste is sorted at the jobsite into various boxes i.e. wood, metal, concrete/inert material, drywall/gypsum, co-mingled recycled waste (small wood scraps, wire cuttings, conduit, metal stud cut offs, etc.), and general trash boxes. A contracted hauler regularly collects these boxes. General trash is taken directly to the landfill where it is weighed and then buried. Separated recycling materials are taken to various certified City of Los Angeles recycling facilities where they are weighed and processed. Co-mingled recycled waste is taken to special certified recycling facilities where the co-mingled mix is weighed and then the recyclable materials are removed from the mix and sent to appropriate facilities for processing. This process does not allow for each recyclable material type from the co-mingled load to be weighed separately. The City of Los Angeles\' Department of Sanitation audits all of the co-mingled sorting facilities on a regular basis and establishes a yearly average recycling percentage rate for "each" facility. The certification recycling percentage rates vary. When calculating the construction waste recycling percentage for MRc2.1, will the USGBC accept the City of Los Angeles\' annual recycling percentage rate for the "specific" facility that accepts this LEED project\'s co-mingled component of the project\'s waste stream?
