  1. State of California2003 Statewide Waste Characterization Study Presentation of Findings

  2. Objectives • Quantify types and amounts of materials disposed in California: • Commercial • Residential • Single-family • Multifamily • Self-hauled • Commercial self-hauled • Residential self-hauled • Examine additional material types not previously quantified: • Electronic items • Certain plastic films • CRV containers • Determine amount of RPPCs disposed

  3. Overview • Collected data in all regions of the state, during four seasons • Sampled at disposal facilities only • Surveyed 4,693 vehicles at 22 facilities throughout the state • Sampled 550 loads/sites • 200 commercial loads • 110 single-family loads & 40 multifamily sites • 200 self-hauled loads • Sorted waste samples into 98 materials • Quantified the waste and calculated average composition for each sector

  4. 18.9 million 12.7 million 8.6 million 47.0% 31.6% 21.3% Commercial Residential Self-hauled Waste Quantities • 40.2 million tons of MSW were disposed in 2003. Tons Disposed in 2003

  5. Waste Composition Highlights • The largest fraction of disposed waste consists of organic materials (30.2%), followed by construction & demolition materials (21.7%) and paper (21.0%). • 20.1% of California’s disposed waste is recyclable. • 24.4% of the waste is compostable. • An additional 16.1% is recoverable C&D materials. • 0.87% of disposed waste is RPPCs; 1.17% is CRV containers.

  6. Top 10 Disposed Materials

  7. Waste Composition

  8. What Materials Are Recyclable? Cardboard & kraft paper 6.7% Other recyclable papers 5.2% Recyclable glass 1.6% Recyclable metals 5.2% HDPE & PETE & some film 1.4% Total recyclable 20.1%

  9. What Materials Are Compostable? Food 14.6% Leaves & grass 4.2% Other kinds of yard waste 2.6% A portion of non-recyclable paper ~ 3.0% Total compostable ~ 24.4%

  10. How much of disposed waste is recoverable C&D material? Concrete 2.4% Lumber 9.6% Gypsum board 1.7% Rock, soil & fines 2.4% Total recoverable C&D 16.1%

  11. Composition by Sector Commercial Residential Self-hauled

  12. = recyclable materials = compostable materials = recoverable C&D materials Recoverability by Sector Residential Commercial 20.5% 23.8% 34.4% 26.4% 11.2% 8.8% Self-hauled 10.7% 6.8% 38.0%
