Background
With the continuous acceleration of the urbanization process in China, a large amount of house-dismantling garbage, spoil, waste and other wastes are generated in the process of building new, modifying/expanding a city and decorating houses by residents. In recent years, the total amount of construction waste generated in China is about 15.5 to 24 hundred million tons each year. The production amount of the construction waste in China can reach a peak value by about 2020.
Due to the dispersity of occurrence forms of the construction wastes, uncertainty of physicochemical properties, instability of acquisition channels and quantity, narrowness of application ranges and the like, the resource utilization process is complex. Particularly, the deep processing technology for recycling the bulk construction waste is lacked at present, the sorting technology is weak, manual quick sorting is mainly relied on, and the disposal technology and the disposal mode are single. Meanwhile, each sorting transfer station has huge pressure, and besides small-scale recycling industrialization of purer waste concrete, decoration garbage, mixed gypsum boards, wood, woven bags and removed garbage with more plastics are difficult to dispose, and the additional value of subsequent products is low due to the technical bottlenecks at the front ends.
At present, the domestic decoration garbage treatment process is not mature, and has no successful project, the established project is mostly temporary or experimental, the treatment is mainly manual, the automation degree of equipment is low, the separation efficiency is poor, and the operation environment is severe.
