Construction and decoration waste resource recovery systemConstruction and decoration waste is produced in the process of interior decoration in urban areas, mainly from construction sites and residential areas. The components from the waste are complex, e.g. glass product, packaging, gypsum board, cement, metal, plastics product, wood board, rubber, etc.The annual output of construction and decoration waste is basically equivalent to that of municipal solid waste (the national annual output of construction and decoration waste ranges from 1.55 billion tons to 2.4 billion tons). Most of its waste are recyclable material, but because of its complex components, it is difficult to classify and separate.The processing flow diagram of construction and decoration wasteThe processing flow diagram of sand making with recycled aggregateStone brickPlasticsWood materialMetallic conduitCardboardStainless steel alloyGypsumConcrete blockScreening effectBefore screeningMaterial after screening: waste metalMaterial after screening: 0-10mm aggregateMaterial after screening: 50mm aggregateMaterial after screening: light fuelResource profit maximizationThe concrete block, sand and stone brick can be recycled as powder, fine aggregate and coarse material, etc. Metal, aluminum and copper can be used in metal recovery and re-refining. Wood material and cardboard canbe used as raw material for organic matter ,so that to recue waste ofresources.Different from the single operation mode in which the landfill collects waste treatment fee, the decoration waste pretreatment line can sell the recycled aggregate and metal as product to enterprises which need the material, so that to earn profit and maximize the profit from resources.Energy saving is reflected in two points. Firstly, the energy consumption of metal and aggregate recycling is far less than the consumption of metal smelting, sand mining and manufacturing. Secondly, RDF fuel can be contained from decoration waste to replace coal and save energy. Harden offers a complete solution for preparing RDF fuel.Most of the decoration waste will be recycled after the preliminary sorting, which reduces the encroachment on the land and the environmental problems caused by the waste combustion to the greatest extent.
