The forms of construction waste in different regions are different, and some seem to have deviated from people's traditional understanding of construction waste. From the treatment point of view, in order to design different treatment processes according to the characteristics of different components of construction waste, we generally subdivide construction waste into four categories by generating sources.
The first kind of high-purity construction waste. This kind of garbage comes from high-purity concrete and bricks selected in the process of mine leveling, new construction and demolition, and the main components are buildings or road main components.
The second kind of low-purity construction waste. This kind of garbage mostly comes from the selection residues in the process of new construction and demolition, or the demolition of building accessories, so the content of muck will be relatively high, and it contains a lot of long combustible materials.
The third category is decoration garbage. Compared with the first two kinds, more complicated construction waste comes from the renovation of new houses, or from the secondary renovation process. There will be relatively more large pieces of garbage and packaging materials in this kind of garbage, and the content of muck and combustible materials will increase greatly. At this time, this part of the decoration waste is completely different from the traditional construction waste.
The fourth category is mixed building decoration pile garbage. Usually, it is a landfill or storage yard for building decoration garbage, and it is mixed with domestic garbage, landscaping garbage, bulky garbage, industrial garbage and a small amount of hazardous waste, and its composition is the most complicated.
