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 2002-2003 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 2003-2004 FY - $990,000 available

Contract Process and Timeline

Scope of Work

• Approach: target specific generators and sources of waste for study

• 4 areas selected for study– commercial sector generators– MRF residuals– Construction and demolition waste– Commercial self-haul

Overall Design

• Focus on major metropolitan areas

• Coordinate field work for all 4 parts – sampling locations, schedules

• Data collected for 2 seasons

• Field work conducted in 2005, data analysis and study report complete by June 2006

Target 1: Commercial Generators

• Method similar to one used in 1999 study• New approach:

– Target most important generators only– Collect disposal composition and diversion data– Design new generator groups as needed

• Data will update and expand waste characterization web database for use by local governments

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

Staff Recommendation

• Approve the award of the contract for Targeted Waste Characterization Studies to Cascadia Consulting Group, and adopt Resolution # 2004-144.
