Classification of construction waste
Construction waste refers to the spoil, abandonment, and other waste generated by the construction group or individual during the process of new construction, alteration, demolition, repair and decoration of various buildings and structures.
According to the source, construction waste can be divided into land excavation, road excavation, old building demolition, building construction and building materials production waste. It mainly consists of concrete blocks, shreds, gravel, waste mortar, Asphalt block, waste plastics, scrap metal materials, waste packaging materials, waste bamboo and other components.
Harm of construction waste
- Occupying land, wasting land resources and reducing soil quality
- damaging the surrounding environment, affecting the air quality
- Pollution and damage to the water
- Waste of resources, increasing transportation costs
Treatment and utilization of construction waste
The current urban construction waste can be separated from metal materials, light materials and plastics by crushing, sorting, screening and cleaning. Then the remaining concrete blocks, gravel and bricks are crushed into a certain size. Recycled aggregate material can be applied to roadbed stone, non-burnt brick, cement admixture, etc.
Waste bricks, waste tiles, concrete blocks, waste wood, and other light materials, scrap metal, etc.
- Building foundation reinforcement material
- Road construction base bedding
- Municipal construction paving brick
- Non-load bearing hollow block
- Recycled aggregate for concrete
- Fuel
- Scrap recycling
Construction waste recycling treatment
- Using resource regeneration technology to depict future blueprints
- Creating a recycling society in which resources are used sustainably
- Protecting the global environment and building a circular society is an eternal theme
Atairac in action
The construction waste crusher has the functions of screening and crushing for coarse and medium crushing of concrete, concrete secondary finished scrap and brick-concrete structure. It has large production capacity, high production capacity, low operating cost, high moisture content, and no bonding materials clogging, uniform product size, and low amount of pulverization.
After sorting, rejecting or pulverizing construction waste, most of them can be reused as renewable resources such as scrap steel, scrap iron wire, waste wire and various scrap steel parts. After sorting, concentrating and re-returning, they can Processing and manufacturing into various specifications of steel; brick, stone, concrete and other waste can be crushed by sand, used for masonry mortar, plastering mortar, concrete cushion, etc., can also be used to make blocks, paving bricks, Building bricks, etc.
The utilization of construction waste resources has been greatly supported by the state, and various policies have been introduced in various places to promote the industrialization of construction waste treatment. For example, the construction waste resource utilization and disposal is included in the scope of the municipal public utility, the construction land is implemented by the government, and the fiscal and taxation preferential policies are enjoyed. The construction waste recycling products are listed in the green building materials catalogue, the government procurement catalog, etc., and the prospects are promising.
Atairac has extensive experience in the recycling of construction waste, with professional fixed and mobile construction waste treatment system solutions in the belt. At the same time of environmental benefits, it can also bring lucrative economic returns to investment users.
