Hazardous wastes are not received. <br /> ' 2. Compostig <br /> Material consisting of leaves, bulky agricultural products, source separated <br /> organic material, and presorted garden waste from the general public and <br /> landscapers is delivered to the composting area shown on Figure 5. Types and <br /> quantities of this material is described below: <br /> TyM of Material Quantity (tons/year) <br /> CURRENT PRCUFCIFD <br /> Leaves delivered by City <br /> of Lodi crews in the fall 4,000 15,000 <br /> Source separated organic material 1,000 5,000 <br /> Presorted wasted from the general <br /> public, landscapers, etc. 1,000 5,000 <br /> Grape stems 1,000 3,000 <br /> Grape pumice 4,000 12,000 <br /> Tomato Waste 3,000 9,000 <br /> TOTAL 14,000 49,000 <br /> Upon receipt, the material is sorted and placed in windrows measuring 8 feet <br /> high, 20 feet wide at the base, and 25 to 400 feet in length. The sorted material <br /> that is contaminated with non-compostable material is transported to the transfer <br /> station or MRF area. Composting is achieved through a natural aerobic process <br /> whereby a controlled environment is created for bacteria to exist. <br /> The rate at which the material will decompose is dictat� by the composition of <br /> athe organic matter being used. Carbon and nitrogen exist in the material as <br /> delivered and the other two elements needed for decomposition, water and oxygen <br /> are added on a regular basis. This is accomplished by the use of a Scarab aerator <br /> which. l' wr� s the windrows every two weeks. Water is added as <br /> necessary to maintain approximately 30 to 50 percent moisture. <br /> hmmuy I os�� 6 <br />
