一. Procedures and steps for building a construction waste treatment plant:

1. According to investment projects, such as a county garbage comprehensive treatment plant, a legal person company is established;

Submit the application documents for the comprehensive treatment of investment waste to the government and the competent department of the investment waste disposal project in the name of the newly established waste comprehensive treatment plant.

          Expanding data: As the urbanization process continues to accelerate, the amount of construction waste generated and discharged in cities is also growing rapidly. While enjoying urban civilization, people are also suffering from the troubles caused by urban garbage. Among them, construction waste accounts for a considerable proportion, accounting for 30% to 40% of total waste. Therefore, how to deal with and use more and more Construction waste has become an important issue faced by government departments at all levels and construction waste disposal units. Many of the waste in construction waste can be reused as renewable resources after being sorted, rejected or crushed. The main ones are:

(1) The use of abandoned building concrete and waste masonry to produce coarse and fine aggregates, which can be used to produce concrete, mortar or other building materials such as blocks, wallboards and floor tiles. After adding the solidified material to the coarse and fine aggregates, it can also be used for the road pavement base.

(2) The use of waste bricks to produce aggregates can be used to produce recycled bricks, blocks, wallboards, floor tiles and other building materials.

(3) The muck can be used for road construction, pile foundation packing, foundation foundation, etc.
