FEB <br />2 1987 <br />BOOK <br />6.7 f1�;E 170 <br />clarified that while <br />this would be a major expense of <br />the county, <br />any economic advantage derived would be only to the benefit of <br />the private waste collectors in that area. <br />Commissioner Bird asked about the advantage to the private <br />home owner. It was noted that there are drop-off sites available <br />for them, and Utilities Director Pinto explained that if we put <br />in the convenience station, our fees would have to increase to <br />the point where it would not be economical for them. <br />Mr. Strowbridge continued that 140 of the annual tonnage at <br />the landfill is simply woody material that can be consumed in a <br />pit burner. They, therefore, recommended continuing with the use <br />of a pit burner and one of a larger size. Animal disposal <br />involves about 2,200 carcasses a year which creates a major <br />problem at the landfill, and that is why they have recommended <br />the purchase and operation of a pathogenic incinerator at an <br />estimated capital cost of about $27,500 and annual operating <br />costs of $15,000. <br />As to resource recovery, Mr. Strowbridge reviewed tech- <br />nology, air emissions, energy markets, etc., and advised that if <br />the County did pursue resource recovery, they would recommend <br />that the mass -burn technology, which is described as follows, be <br />accepted. <br />166.3.1 MASS BURN SYSTEMS <br />The combustion of unprocessed solid waste, combined with heat recovery, is <br />currently the most widely practiced energy recovery technique in the world. <br />In a plant designed for mass burning, unprepared refuse (as received from <br />the collection vehicles with little or no sorting) is charged directly into <br />a combustion furnace and the heat generated by the combustion process is <br />recovered by waterwall radiation boilers in the form of steam. The steam <br />may be sold directly to a customer or converted to saleable electricity by <br />a turbine generator. <br />In the energy market evaluation, Mr. Strowbridge reported <br />that the energy products considered were steam and electricity. <br />Unfortunately, there are no major steam users in the county, and <br />6 <br />
