determined by multiplying the new industrial generation rate by the number of <br />manufacturing employees in Table 111-2. <br /> <br />Construction or~d Demolition Wosle. A considerable amount of waste is also generated by <br />contract conslruction firms, most of which is construction and demolition waste. The <br />omounl and ~ype of waste varies substantially depending on lhe proiect and on ~h'e general <br />level of economic activity in the region. The Anoka County Solid Waste Quantit.,v.Study <br />reflects construction and demolition waste generated in the Counly except for loads <br />which contained very little combustible malarial. <br /> <br />Waste Tires. A recent sludy on scrap tires prepared for the Minnesota Pollution Conlrol <br />Agency identified 03 poientiaJ scrap lire generators in Anoka County. Scrap tire <br />generators consist of the following business types: gasoline service stations, tire dealers <br />and retreaders, automotive service cenlers, truck service centers, and new aulomobile <br />dealers. Ths study also determined a storewide scrap tire generation rate of 0.8 <br />tires/capita/year (Waste Recovery, Inc., 1985). Tires are expressed in Passenger Tire <br />Equivalents, which include auto-light Iruck, tractor, truck and duplex tires. .In order to <br />estimate the annual quantity of scrap tires produced in Anoka County~ that generation <br />rate was multiplied by the County's populatior~. It is assumed that the scrap tire <br />generation rate has remained constanl from 1980 through 1985, and that it will not change <br />during the next fifteen years. Tablelll-L~summarizes the estimated number and weight of <br />scrap tires generated in 1985, and projected to 1990 and 2000. <br /> <br />Waste Quantity Projections <br /> <br />Table Iii~5 shows waste quantity projections for Anoka County, which are disaggregated <br />by source of material in Table III-&. It has been assumed that increases in waste <br />quantities will be proportionate to increases in population. There is some speculation <br />concerning future changes -irk waste garter'arian rates. Certain literature sources such as <br />the 1977 EPA Fourth Report to Conaress indicate that the tolol per copilo rate will rise <br />in the next few years. However, the waste generation rate is assumed not to change over <br />time because future waste reduction and abatement lechniques may offset any increase in <br />packaging and related influences. <br /> <br /> <br />
