THE SCIENCE OF SANITARY ODORLESS COMPOSTING FOR MUNICIPALITY OR HOME USE INTRODUCTORY FAC'T'S & FIGURES FOR 1983 Landfill disposal of leaves and other organic wastes cost taxpayers $35.00 and more per ton in the Boston, New York and Philadelphia areas To bury the daily wastes of cities throughout the U.S. would require a hole 10 feet deep covering an area of 400 acres. By contrast, finished composts finds a good market @ $20.00 per tdn . in 20 toniloads in these same metropolitan areas. In New York City there are several small production plants producing thousands of tons annually. Small processing plants in urban areas are efficient, as they are located near waste sources and potential markets saving on the largest single cost, transportation. City waste can become fertile farm soil. As a national policy we aren't making soil but contributing to desertification. The world's two billion acres of dessert, according to the United Nations, might become seven and a half billion acres by the year 2000. The Mississippi carries away 40,000 tons of soil every hour. The U.S.D.A. reports some farmland is losing 40 tons topsoil per acre annually. 11111 METHODOLOGY OF COMPOSTING There are two basic methods-of-composting. One is the hot method, whethe temperatures reach up to pasteurizing range within the pile. this method is most adaptable of waste on the municipal level. Second, is composting via the cold method, best utilized when there are smaller accumulations or a variety of waste such as homeowners would have. The hot method of municipal composting, leaves are piled in long windrows 10 to 12 feet wide by 8 feet high. The windrows are built up and down the grades or contours of the site, so surface waters can drain away between the piles. Municipal dump trucks can be fitted with 15 cubic yard capacity, 3/4" exterior plywood boxes. Air vent on top, opening to receive hose in back, with a large back door opening to dump. Box is just bolted to steel dump body. On the highway the truck pulls a trailer mounted vacuum leaf collector reducing the volume of leaves as blower . packs them into the box. When the truck is loaded, the vacuum trailer is disconnected and reconnected to the next empty standby truck; Vacuum is almost constantly in operation, while loaded truck WINDROW COMPOSTING travels to the compost site. At the site, the driver dumps his load to make an orderly straight line windrow, dumping close enough together to make a continuous �� ,j; windrow. A front end loader may be used to tidy the .
