Metals <br />Metals represent about 2.5% of the waste stream on average. We assume a maximum of 90% of <br />that could be captured. We are now capturing an estimated 40% or 30 tons per month. The <br />markets are long -term and stable although prices vary widely, beginning at $30 per ton last year <br />down to $10 per ton now. <br />All other C &D materials <br />The remaining materials including carpet, insulation, plastics, treated and painted wood and <br />other unrecoverable materials make up an average 11% of the waste stream. While there are <br />some emerging markets for certain types of carpeting and other specialty materials, these are a <br />very small amount of our waste and must be thoroughly separated to have any market value at <br />all. <br />B. Waste Tonnage Projections <br />Below in Table lb, we present six years of data from separated landfilling of construction and <br />demolition waste from mixed waste. Prior to 1993, we combined C &D waste with mixed solid <br />waste, separating out only the inert debris, yard waste and stumps. Generally C &D has averaged <br />about one -third of the overall waste stream, excluding coal ash. <br />It is difficult to predict the flow of construction and demolition waste in Orange County. <br />We have presented a truncated table of possible future C &D generation based on a report <br />submitted previously to the Owners Group by Joyce Engineering as part of our C &D landfill <br />search. Their tonnages to be landfilled already assume a diversion rate of 10 %. <br />A review of the fluctuation in C &D waste landfilled in Table 1 b shows no correlation with the <br />population growth in Orange County. There is also no correlation with implementation of <br />construction and demolition waste reduction efforts except that, in general, C &D landfilled per <br />capita is below the baseline 1991 -92, for each year of record in which C &D was landfilled <br />separately from mixed solid waste. <br />rI <br />
