Material Classes in the Overall Disposed Waste Stream, 1999

Background Strategic Plan calls for waste characterization study every 4 years First statewide study done in 1999 Budget Change Proposal (BCP) for large new study was developed for Fiscal Year (FY) but did not go forward Contract Concept for smaller statewide study approved Fall 2002 – study is now under way Updated BCP for larger study approved for FY - $990,000 available

Target 2: Materials Recovery Facility (MRF) Residuals Quantify and characterize residuals from Materials Recovery Facilities and Solid Waste Processing Facilities (clean and dirty MRFs) Develop listing and survey major MRFs Classify into sampling groups Field sampling and sorting of residuals for each group

Target 3: Construction & Demolition Waste Develop reliable volume-to-weight conversion factors for detailed C&D material types Develop visual characterization method for CIWMB and local government use Use new method to characterize C&D waste Characterize 5 sources of C&D waste

Target 4: Commercial Self-Haul “Other commercial” (non-C&D) self-haul “Drop box” containers provided by haulers (non-C&D) Characterization of materials Identify sources and activities generating the waste Survey materials recovered from loads
