Recycling Pilot Program Summary <br />Conclusions <br />The Project Team has summarized the results of the City's recycling pilot program as <br />follows: <br />^ The largest increase in the number of set-outs occurred in the single-stream and <br />larger bin capacity routes. <br />^ The largest increase in participation occurred in the larger bin capacity routes. <br />^ The largest increase in quantities of material collected per household occurred in <br />the single-stream and larger bin capacity routes. <br />Based on the tonnages collected during the pilot routes, it is estimated that on an <br />annual basis, the amount of recyclable materials collected weekly would be <br />comparable to the quantities collected on asingle-stream route. <br />The composition of the single-stream routes showed increased percentages of <br />paper collected, decreased percentages of metals, glass and plastic, and an <br />increase in the percentages of non-targeted materials. However, the net quantities <br />collected in the single-stream routes were greater than the dual-stream routes. <br />The pilot route that was provided increased public education materials did not <br />result in a statistically significant increase in the quantity of materials set out at <br />the curb. <br />Opportunities for improving curbside recycling in any given municipality are truly <br />program-specific. The City of Roseville has a very mature program and its pilot <br />program results may differ if compared to other programs. Cities need to decide the <br />optimal curbside recyclable materials collection program based on a range of issues <br />including cost, materials recovery levels, participation, and customer preference. <br />Finally, the Roseville pilot project had many other benefits including discussions <br />regarding: <br />The value of pilot projects versus converting to a city-wide with program changes <br />without such field demonstrations; <br />^ Recycling contract compliance and performance monitoring; <br />Proposed definitions of contaminants or residuals from the various points in the <br />recycling system: <br />at the curb ("non-targeted materials") <br />^ from the MRF ("processing residuals") <br />at the mill ("prohibitives" and "outthrows"; e.g., cross-material <br />contamination in paper bales) <br />Proposed methodologies for measuring contamination at each of the three points <br />listed above; <br />Proposed standard methods for curbside recyclables composition analysis; <br />20 DRAFT s~6os <br />
