<br />TCMRF Single-Sort Constituent Test <br /> <br />INTRODUCTION AND PURPOSE <br /> <br />Recycle America Alliance (RAA) and Waste Management (WM) conducted a test at the <br />Twin Cities Materials Recovery Facility (TCMRF) on October 18,2003 to better define <br />the constituents of "single-sort" collection and processing. The TCMRF is an integrated <br />facility accepting materials from several types of collection styles (streams). The process <br />lines are linked and various streams are processed concurrently on the process lines <br />during normal operations. Therefore, a separate running of just single-sort material was <br />required to classify constituents and process results for this stream. <br /> <br />DESCRIPTION OF TEST PROCEDURES <br /> <br />Receipt of Test Materials: WM collection operations were instrumental in delivering <br />single-sort materials to the TCMRF on a Saturday morning for a separate test run of this <br />stream. The test materials were collected through the course of normal collection <br />operations on Friday, October 17, 2003 and held over for delivery to the TCMRF on <br />Saturday, October 18, 2003. <br /> <br />In order to provide a reference test for single-sort collection and processing, only <br />materials collected in a fashion representing WM's representation of "single-sort" in the <br />Twin Cities market were delivered. The following are key points in this definition: <br /> <br />. Materials are designated for recycling by the resident and separated from waste items. <br />In other words the materials are source-separated for recycling purposes. <br />. Materials are placed in a cart for collection. The cart may be of differing size (32, 64, <br />96 gallon) depending on the preference of the resident but the cart has an integral lid. <br />. Materials are collected in either an automatic or semi-automatic collection vehicle. <br />. The collection vehicle has one chamber for the combined materials with a compaction <br />rate of four to one. <br /> <br />TABLE 1- MATERIAL RECEIPTS FOR TEST ON OCTOBER 18. 2003 <br /> <br />Truck 1ubouud Wei!!ht Outbound Wei!!ht Net Wei!!ht (Tons) Ori!!in <br />I 48,520 36,000 6.26 Brooklvn Center <br />2 42,600 35,740 3.43 Brooklvn Center <br />3 46,500 34,460 6.02 Brooklvn Center <br />4 41,580 36,560 2.51 Brooklyn Center <br />5 46,260 34,120 6.07 Lino Lakes <br />6 47,640 35,800 5.92 Brooklvn Center <br />7 45,420 38,000 3.71 Eden Prairie <br />8 47,900 31,960 7.97 Bloomin~ton <br />9 51,580 36,280 7.65 B1oomin~ton <br />10 52,980 38,160 7.41 Richfield <br />11 35,360 27,560 3.90 West Lakeland <br />12 34,060 27,900 3.08 Centerville <br />13 39,380 27,960 5.71 Robbinsdale <br />14 44,920 32,660 6.13 Circle Pines <br /> <br />2 <br />
