Floor conveyors could be installed to cavy the recyclable fraction, from <br /> the sorting building, into the adjacent MRF building, after bulky wastes (e.g., tires, <br /> white goods, mattresses, construction debris) have been removed. <br /> The interior of the MRF building could contain sorting lines, a baler, a shredder, <br /> and a materials storage area. Baled material would be loaded onto trucks for <br /> transportation to market. Shredded wood waste could be screened into chips <br /> and compostable fines. Tires, white goods, construction debris, and mattresses <br /> could be stockpiled outside for batch processing when sufficient quantities <br /> accumulate. <br /> Composting Area <br /> The proposed NCSL composting area also located in Module 11, east of the <br /> sorting building, could receive and process the fine organic materials from the <br /> materials recovery area. <br /> The NCSL site is well suited for a composting operation for the following reasons: <br /> 1. Adequate Site Area: Composting, in the conventional windrow <br /> fashion, is very land intensive. With a 36-year design life, the <br /> landfill cells designated for the end of the fill sequence will be <br /> unoccupied for many years and therefore available for ongoing <br /> compost operations. <br /> 2. Available Water Supply: Effective composting requires a <br /> significant volume of water to optimize the microbial decomposition <br /> of organic material. The existing on-site well may be an adequate <br /> supply. <br /> 3. Favorable Adjacent Use: One of the biggest concerns with <br /> composting is the production of offensive gases. The rural setting <br /> of the NCSL make it less subject-to the potential for complaints <br /> from adjacent residents and businesses. <br /> Composting has been commonly used for degradation of leaves, lawn clipping, <br /> and municipal sewage sludge; with the advent of the ISWMA diversion <br /> requirements the following waste components may be targets for biologic <br /> stabilization: <br /> • Food waste <br /> • Contaminant or wet paper waste <br /> 0 Refractory organic fabrics, and building materials <br />
