Research of RDF-raw materials for prospective use in hardening construction and agricultural technologies

Abstract

In article research methods of recycling waste. The main selected methods - the development of fertilizers for soils and the creation of innovative building material. Currently, according to the Housing Committee of Administration of St.-Petersburg annually on landfill sites is disposed of 6.5 - 9 million cubic meters per year. Of this volume, only 1.5 million cubic meters (17-23%) is sent for processing in two landfills ("Novoselki" and JSC "Pilot plant MPBO-2 Yanino", project storage tailings according to an approximate assessment have 50 000 tons of RDF-raw materials). Also in St. Petersburg and the adjacent territory of the Leningrad region there are about 250 unauthorized dumps, which are placed, according to very rough estimates, from 500 thousand to 1 million cubic meters of garbage. A distinctive feature of illegal dumps is the high concentration of heavy and rare metals in the garbage. The article discusses the possibility of using aerobic waste composting as a fertilizer for soil and a solid building material, or alternative solid binder, highly abrasive granules. The applied research methods suggest that RDF wastes are commercialized and have the prospect of becoming a separate innovative product.
