Organics Diversion Calculation, Town of Chapel Hill <br /> <br /> <br />4.3.2.3 Key Elements of an Organics Diversion Program <br /> Organics diversion programs commonly involve the following elements: <br /> Educational Programs. As with other recycling efforts, an effective separate food <br />waste organics collection program, whether residential and/or commercial, involves <br />significant public education and communication. If the Town were to elect to <br />implement curbside collection of food wastes, significant public education would be <br />needed to communicate the objectives, schedule, and procedures for storing and <br />collecting this waste stream so as to not create health concerns or nuisances such as <br />odors, insects, or rodents. The Town has experience with public education programs <br />associated with its existing yard waste and recycling programs, and there are <br />resources available from communities which have implemented separate organics <br />diversion programs. <br /> Collection. Typically, residential and/or commercial food waste needs to be collected <br />separately from the other waste streams, although yard waste and food waste <br />collection can sometimes be combined. For example, the City of Toronto has <br />recently implemented a program that collects yard waste and food waste together. <br />The additional costs resulting from the separate curbside collection of food waste is <br />one of the major barriers to implementing a residential organics diversion program. <br />Additional collection costs would include new collection vehicles (amortized costs, <br />Calculation Methodology, Town of Chapel Hill, NC <br />Organics Diversion Scenario <br />Residential <br />Method No. 1 - Based on Waste Composition <br />Food Waste % <br />Residential Waste 6500 tons/year 26% 1,690 tons/year <br />Method No. 2 - Based on Per Household Generation <br />Low 5 lbs/HH/week 11,500 Households 1,495 tons/year <br />High 10 lbs/HH/week 11,500 Households 2,990 tons/year <br />Potential food waste generation: 1495-2990 tons/year <br />For Pro Forma (only include residential) <br />8 lbs/HH/week 11500 Households 2,392 tons/year <br />Capture rate 50% <br />1,200 tons/year <br />Commercial (potential additional recovery) <br />8,590 tons 26.00% 2,233 tons <br />Capture rate 25% <br />600 tons/year
