METHOD FOR EXTERMINATION OF WASTE IN EXISTING DUMPS AND DEVICE FOR PROCESSING OF DUMP WASTES Russian patent published in 2009 - IPC B09B3/00 

FIELD: environmental protection.

SUBSTANCE: group of inventions is related to the field of environmental protection, namely to method and device for recycling of domestic wastes and industrial waste of existing dumps until their complete elimination. Bulldoser, and then auger profiler are used to create technological cyclically processing sites along the whole area of dump. Sites are covered with layers of dried peat or wood chips. Then in process of extraction large and small inclusions of metal scrap, stones and incombustible hard construction wastes they are mixed by rotor of stubbing machine followed by stone collector, which extract and separate solid inclusions of waste and their transportation into hopper-accumulators. Cleaned technological site mixed with peat and/or wood chips is milled by surface-layerwise method by miller with disk mills to produce waste chips. Produced chip is dried and turned by agitators and assembled into stacks by stacker machine from cylinders arranged with roller machines, for further transportation to pyrolysis plant. In pyrolysis plant combustible fuel is made from waste chip for internal combustion engines of the pyrolysis plant itself and complex of peat and transport machines, and also for provision of heat, hot water and electricity.

EFFECT: liquidation of waste accumulated in existing dumps for 8-10 years with complete preservation of environment without expenditure of funds from city budget.
