Statewide Market for Materials
Perceived Impact of Clopyralid on Compost Sales
Response to Production Cost Increase Due to PR1133
Impact of Green Waste ADC Use -Statewide-
Impacts of ADC on Composters by Region
Impact of Green Waste ADC Use on Processors by Region
ADC Impacts on Composting & Processing Businesses
Key Findings
Number of facilities constant; 10 Million Tons Diverted
Ag is the largest single market for urban compost
CalTrans remains an untapped market
Large increase in ADC use --8.4 million cu (47% of market)
ADC use has impacted compost facilities in some regions of Ca.
28% decline in Compost Production
Areas for Further Study
Study the impact of ADC on the compost industry
Identify those sectors of agricultural that buy compost
Work with CalTrans to increase market Include financial and employment data in
subsequent study
Implications of Study on CIWMB
1. Green Waste ADC Continues to Increase
Implications of Study on CIWMB-2-
2. Compost Production Decreased 28%
3. 45% Diversion 2003
33% Diversion 2001
Implications of Study on CIWMB-3-
4. Does Green Waste ADC Impact Compost Markets?
