Processing Residuals The previous section addressed contamination with non-targeted materials by residents at the curb. Once recovered materials were collected, they were taken to Waste Management's MRF in Minneapolis for processing during the pilot project.. Actual data from the processing of the collected materials was not provided to the City as part of the pilot study. However, the Project Team reviewed literature regarding processing residuals. In addition, Waste Management provided the results of an internal study of materials processing at the Minneapolis MRF in 2003 of single- stream collected materials. Based on this literature review, key items regarding processing residuals and other contamination issues included the following: Waste Management Study The study was performed for materials collected only from selected single-stream routes in the Twin Cities area (normally this MRF processes material from non- single-stream sources as well). The Waste Management study reported that 5.95% of total inputs became residuals. These materials included both contamination by residents at the curb (non-targeted materials) and residuals from facility operations (processing residuals, such as dirt and very small pieces of material). The Project Team notes that the Waste Management study considered both the 2% of total products as color-sorted glass and 11 % of total products as color- mixed, broken glass. Both forms of glass were defined as a recycled product. Were the 11 % of color-mixed, broken glass not considered to be a marketed, recycled commodity, the residual rate would be nearly 17% for this facility (5.95% from other reported residuals plus the 11 % from color-mixed broken glass). si6os DRAFT 15
