88 Page 60 Functionality and Capability System Throuqhout HBC's system, as proposed, has a combined throughput rating of 60 tons per hour, with 30 tons per hour for residential and 30 tons per hour for commercial recyclable materials. Separation Abilitv. Automation and Technoloav The objective of the Ti~Tech design is to singulate the material thereby giving the optical recognition device the opportunity to clearly identify the target material and then prompt the air system to eject the target material alone. It will be a significant challenge to singulate newspaper at these volumes and effectively remove containers without also taking a measurable amount of paper. As designed, any fiber that is ejected along with the containers will be delivered to the "banana" screen. This may result in the . contamination of downstream materials if the "banana" screen is overburdened by GNP (that had been previously removed by the News Screens). The VDB process description states that the system can be run without any quality control (OC) sorters on the paper lines. The process flow diagram shows the OCC being taken manually. Regardless of advancements in optical technology before the installation of the new system, it is likely that QC sorters will be needed in order to consistently remove the "browns" from the ONP stream and attain the highest value for the recovered fiber products. Ti- Tech PaperSort eN 2000 (2-units) - These units are dedicated to the recovery of containers from the ONP stream. Each unit is fed with 79" speed belt. The flow of news in a 25-30 tph system over a 79" wide belt may not be sufficiently singulated. Because of the burden depth required by the 15 tph (approx.) flow of ONP, the system's ability to consistently recognize and recover PET and aluminum will be challenged. The Ti-tech guarantee requires the delivery of a precise defined stream of material. Ti. Tech PaperSort eN 2800 (2-units) - These units are dedicated to the recovery of containers from the OMP stream. Because the burden depth of the OMP stream should be significantly less than that of ONP, the potential for singulation problems, as described above, are much less likely. PolySort 2000, PolySort 2800, and AutoSort 1400 - Each of these devices are applied to the recovery of all plastics from the container stream. The remaining items, aluminum cans, tin cans, and residue are recovered by magnets, eddy currents, screens, and air. Fines Screen - As described in the equipment description, VDB's fines screen utilizes steel discs in the initial screen impact area and rubber discs thereafter. Because broken glass is the most abrasive of all materials in the single~stream process, there is a reasonable expectation of excessive wear to the rubber discs. As discs wear, the spaces between the discs become enlarged. As the spaces widen, the potential for losing the smaller PET bottles and UBC's increases. SBWMA ~ EC Report Page 36 1/15/2009
