TCMRF Single-Sort Constituent Test INTRODUCTION AND PURPOSE Recycle America Alliance (RAA) and Waste Management (WM) conducted a test at the Twin Cities Materials Recovery Facility (TCMRF) on October 18,2003 to better define the constituents of "single-sort" collection and processing. The TCMRF is an integrated facility accepting materials from several types of collection styles (streams). The process lines are linked and various streams are processed concurrently on the process lines during normal operations. Therefore, a separate running of just single-sort material was required to classify constituents and process results for this stream. DESCRIPTION OF TEST PROCEDURES Receipt of Test Materials: WM collection operations were instrumental in delivering single-sort materials to the TCMRF on a Saturday morning for a separate test run of this stream. The test materials were collected through the course of normal collection operations on Friday, October 17, 2003 and held over for delivery to the TCMRF on Saturday, October 18, 2003. In order to provide a reference test for single-sort collection and processing, only materials collected in a fashion representing WM's representation of "single-sort" in the Twin Cities market were delivered. The following are key points in this definition: . Materials are designated for recycling by the resident and separated from waste items. In other words the materials are source-separated for recycling purposes. . Materials are placed in a cart for collection. The cart may be of differing size (32, 64, 96 gallon) depending on the preference of the resident but the cart has an integral lid. . Materials are collected in either an automatic or semi-automatic collection vehicle. . The collection vehicle has one chamber for the combined materials with a compaction rate of four to one.
