Appendix A Policy Implications Several key recycling and solid waste management policy questions are raised within the City of Roseville's pilot collection study and this analysis. Role of the Cities in Minimizing Disposal of Materials Collected for Recycling - Each local municipality has some role in assuring the materials collected for recycling by its contractor are indeed recycled to the maximum extent feasible. The negative public relations caused by materials unnecessarily disposed as waste are a major threat to the residents' trust that is essential in continuously encouraging, maintaining, and improving participation in municipal recycling programs. This is true regardless of collection method (i.e., dual- stream vs. single- stream). There are a variety of optional procedures that a city can implement to maximize recycling and minimize unnecessary disposal of materials collected. These options may not be mutually exclusive and include: ■ Tacitly encourage the contractor to maximize recycling. ■ Work to provide clear, consistent city- published public education tools as to materials to be included for recycling and excluded (non targeted materials). ■ During recycling service procurement (e.g., during development of request for proposals and contract negotiations, etc.): • Adopt clear definitions of terms, including "targeted materials ", "non- targeted materials ", and "processing residuals"; • Specify public education tools to be provided by the contractor and require that the city approve the education materials before they are distributed; • Consciously decide if the contractor shall provide a truck -side quality inspection function (i.e., will materials be rejected by the collection crew and education tags left in the curbside bin); • Specify a maximum processing residuals rate and an agreed upon measurement scheme for objectively monitoring this rate; and /or • Specify a liquidated damage charge to be imposed on the contractor if the maximum processing residual rate is exceeded. Role of the Government in Minimizing Disposal of Materials Collected for Recycling — Provision of standardized definitions, more research, and clear policy direction as to acceptable levels of process residuals would assist cities and haulers with the best available information about the processing residuals issue. For example, there is still little hard data available that characterizes the color- mixed, broken glass generated from MRFs in Minnesota. We still do not know how much single - stream collection and processing systems impact the relative amounts of mixed glass produced compared dual- stream systems. A-V B1605
