Hennepin County, Minnesota

Studies were conducted in the Minneapolis/St Paul, Minnesota area in 1990 by the Council for Solid Waste Solutions and the local governments [CSWS, 1990]. The purpose of the work was to assess the feasibility of collecting plastics at curbside in Hennepin County, Minnesota. This study illustrates the addition of various plastics to existing recycling programs using differing collection vehicles and presented details related to composition and collection. 

The programs consisted of adding curbside collection of plastics to five existing routes 3 routes in the city of Minneapolis, 1 route in the city of Minnetonka and 1 route in three nonhwestem suburbs known as the Hennepin County Recycling Group (HRG). The three Minneapolis routes collected biweekly and the other two routes collected weekly. All methods utilized curbside sortation of material. The study duration was roughly three months. A summary of collection methods for each route is shown in Table 2.7. All field data were collected over a one month period by Cal Recovery Systems, Inc. 

Compositions and estimates of collection amounts of the different plastics collected from the above described curbside programs are shown in Table 2.8. The specified plastics for the collection area are shown at the top of the table, and the estimated generation p er household served per year and proportion of each plastic are shown within the table. The compositions shown do not include non-plastic contaminants. These data should be directly applicable to other moderate to large sized cities located in the midwest
