What is the investment of construction garbage management system？

The recycled fine aggregate produced by recycling equipment such as construction waste classification can be used for 15 new environmentally friendly building materials such as paving bricks, and the recycled coarse aggregate can be used for paving, which really realizes low cost and high profit.
Construction waste is not real garbage, but misplaced garbage "gold". Most construction waste can be reused as renewable resources after being classified, removed or crushed. Metals such as scrap steel bars, scrap iron wires, and scrap wires can be reprocessed into various specifications of steel after being classified, concentrated, and recycled; waste bamboo and wood can be used to make artificial wood, making construction waste recycling with high utilization rate and production cost. Low cost, wide range of use, good environmental and economic benefits.
 
Construction waste refers to spoils, wastes and other wastes generated by construction units and construction units in the process of new construction, reconstruction, expansion, and demolition of various buildings, structures, and pipe networks. Therefore, how to do a good job in the recycling of construction waste has become one of the main tasks that need to be done at present.
 
Guided by the reduction, recycling, and harmless disposal of construction waste, and in accordance with the principle of “regional digestion as the mainstay, and cross-regional balance as the supplement” for reduction, recycling, and harmless disposal, comprehensive utilization and standardized disposal are solidly promoted. . According to the management specification, no unit or individual shall set up a waste site without authorization to accept construction waste; construction waste transported by individuals or units engaged in construction waste transportation without approval; construction waste that has not been recorded as required for cross-regional balance disposal shall not be accepted ; Do not accept construction waste mixed with industrial waste, domestic waste, sludge, medical waste, hazardous waste, toxic and hazardous waste, and standardized management.
As a mixture of various building material wastes, construction waste is directly landfilled without treatment, which not only destroys the natural environment, but also is a huge waste of resources. If construction waste is recycled, construction waste can be turned into treasure and reused as a renewable resource, which is an effective way to save resources and protect the environment.
Part of the construction waste can be reused after being sorted, removed or crushed. The following uses are available:
(1) After the construction waste is crushed, it is divided into coarse and fine aggregates to replace natural aggregates to prepare concrete, road substrates and building bricks.
(2) Steel doors and windows, scrap steel bars, nails, cast iron pipes, and black and white iron sheets are sorted and sent to non-ferrous metal smelters or iron and steel plants for re-smelting.
(3) Waste bricks can be reused after cleaning. Waste ceramic tiles and ceramic sanitary ware are crushed and sorted, and the ingredients are pressed and formed to produce permeable floor tiles or sintered floor tiles.
(4) After the waste glass is screened, it is sent to a glass-ceramic factory or a glass factory to produce glass or glass-ceramic.
(5) Wooden roof trusses, wooden doors and windows can be reused or processed, or used to make MDF, or compressed into biomass fuel pellets.
(6) Various plastics can be dissolved, compressed and drawn, and cut into plastic particles.
