With the continuous development of society and the rapid economic development, the phenomenon of garbage surrounding cities is common. Especially for construction waste, every new 10,000 square meters of building generates 500-600 tons of construction waste; every demolition of 10,000 square meters of old buildings generates 7,000-12,000 tons of construction waste; by 2020, my country will add about 30 billion square meters of new construction area. According to incomplete statistics, the existing construction waste in my country has reached 3.5 billion tons, and the annual increase in construction waste is about 1.5 billion tons. The astonishing scale of construction waste makes us suffer from the "garbage siege" while enjoying civilization. The most terrible thing is that these garbage will continue to increase gradually in the next 5-8 years. Faced with such a situation, traditional disposal methods not only occupy land and pollute water resources, but also cause waste of resources. The resource utilization of construction waste has become an effective way to solve the problem of urban construction waste.

Where should the demolished or abandoned construction waste go and how to deal with it? Maybe you have heard of this phrase - "trash turns into gold". Yes, there is no trash in the world, it's just that the resources are placed in the wrong place! One-stop resource disposal solution for construction waste

The resource recycling of construction waste is a comprehensive project. It is necessary to start from system construction, source control, technical research, and concept change, and gradually establish a set of construction waste treatment systems and technologies that embody "reduction, resource utilization, harmlessness, and industrialization", so as to realize the resource utilization and industrialization of construction waste. There is no worry about the location of construction, no worry about raw materials for disposal, and no worry about sales for products - only by forming a closed construction waste recycling chain can the rebirth of construction waste be unblocked.

"Construction waste" and "resources" are only one "reuse" away

The recycled aggregates of construction waste after crushing, screening, iron removal, light material separation and other processes are processed into permeable bricks, recycled mortar, PC prefabricated components, road water-stabilizing layers, dry powder mortar, RDF clean combustion rods and other environmentally friendly building materials products, thereby turning construction waste into treasure and achieving the win-win goals of ecological benefits, social benefits, economic benefits and other multi-party benefits.

1. Recycled aggregate: It is the main product of resource disposal of construction waste. It has good permeability, does not freeze or shrink when exposed to water, has a large specific surface area, and is not plastic. It is widely used in road engineering fields such as road cushion, subbase, base and water-stabilizing layer.

2. Recycled permeable bricks: It can make rainwater quickly penetrate into the surface and return to groundwater, so that groundwater resources can be replenished in time. It is widely used in sponge city construction.

3. Recycled concrete: Recycled concrete made of recycled aggregates from construction waste instead of natural aggregates such as sand and gravel, and then added with cement, water, etc.

4. Recycled premixed mortar: It is a new type of environmentally friendly green building material with superior performance, convenient construction, ready to use, and can avoid air pollution caused by on-site mixing.

5. Recycled small prefabricated components: Various small prefabricated components such as urban road side stones (kerbstones), ditch covers, roadbed covers, tunnel ditches and covers are made of recycled graded aggregates from construction waste as raw materials.
