Today, humanity continually produces a lot of various waste products from industrial and domestic origin. Accumulating these wastes become a real disaster, and that is why the importance of every new technology of recycling.The most common way to deal with the waste and its disposal is burning, but the technology is recognized deadlock, because the cost of burning 1 kg of garbage are very significant.Therefore, great importance is the development of technologies of processing waste, due to which it becomes possible to get new useful products and, as a result, to achieve a positive economic effect. Differ in methods of processing of combustible rotting, medical waste. Technology of processing of combustible waste This technology involves the processing of combustible waste with the help of combustible gas in the closed reactor.Thus, it is possible to process waste types such as dry biomass (sawdust, bark, wood waste), waste water after draining, solid oil products (automobile plastic, rubber, fabric, wood, foams), industrial solid waste (any non-toxic waste plastic, paper, cardboard and etc), as well as the allocated when sorting household waste combustible fraction. Technology of processing of rotting waste The technology of processing of garbage assumes its processing in reactors with bacteria that produce methane and make recyclable garbage in humus or biogas.Thus it is possible to recycle waste treatment facilities and farms, resulting compost, humus, which can then be used in agricultural and horticultural work. In addition, methane can be used in production of heat and electricity. Recycling and treatment of medical waste involves: sterilization of needles, medical containers, metal probes, glasses, biological cultures, physiological substances, syringes filters bubbles catheters, diapers, laboratory waste etc.
