Recycling Pilot Program Summary Conclusions The Project Team has summarized the results of the City's recycling pilot program as follows: • The largest increase in the number of set -outs occurred in the single- stream and larger bin capacity routes. • The largest increase in participation occurred in the larger bin capacity routes. • The largest increase in quantities of material collected per household occurred in the single- stream and larger bin capacity routes. ■ Based on the tonnages collected during the pilot routes, it is estimated that on an annual basis, the amount of recyclable materials collected weekly would be comparable to the quantities collected on a single - stream route. ■ The composition of the single- stream routes showed increased percentages of paper collected, decreased percentages of metals, glass and plastic, and an increase in the percentages of non - targeted materials. However, the net quantities collected in the single- stream routes were greater than the dual- stream routes. ■ The pilot route that was provided increased public education materials did not result in a statistically significant increase in the quantity of materials set out at the curb. Opportunities for improving curbside recycling in any given municipality are truly program- specific. The City of Roseville has a very mature program and its pilot program results may differ if compared to other programs. Cities need to decide the optimal curbside recyclable materials collection program based on a range of issues including cost, materials recovery levels, participation, and customer preference. Finally, the Roseville pilot project had many other benefits including discussions regarding: ■ The value of pilot projects versus converting to a city -wide with program changes without such field demonstrations; ■ Recycling contract compliance and performance monitoring; ■ Proposed definitions of contaminants or residuals from the various points in the recycling system: ■ at the curb ( "non- targeted materials ") ■ from the MRF ( "processing residuals ") ■ at the mill ( "prohibitives" and "outthrows "; e.g., cross - material contamination in paper bales) ■ Proposed methodologies for measuring contamination at each of the three points listed above; ■ Proposed standard methods for curbside recyclables composition analysis; 20 DRAFT B1605
