Construction waste refers to the residual mud, slag, mud and other wastes generated by construction, construction units or individuals in the process of construction, demolition, repair and decoration of various buildings and structures, as well as residents' houses. There are roughly three ways to classify construction waste: one is classification by source, classification by physical composition, and classification by reuse performance.

1. Land excavation waste

It is divided into topsoil and deep soil. The former can be used for planting, and the latter is mainly used for backfilling, landscaping, etc. This type of construction waste is characterized by large production volume, relatively simple physical composition, concentrated production time, and less pollution.

2. Road excavation waste

It is divided into concrete road excavation and asphalt road excavation. Including waste concrete blocks and asphalt concrete blocks. The physical composition of this part of the garbage is more complex and has availability, but it is also highly polluting. Abandoned concrete blocks and asphalt concrete blocks can be processed after recycling to separate reusable gravel, etc. However, if it is piled up and not used, it will cause land pollution and occupy land resources, reducing land utilization rate due to its resistance to decomposition.

3. Garbage from demolition of old buildings

It is mainly divided into bricks and stones, concrete, wood, plastic, gypsum and mortar, roofing waste, steel and non-ferrous metals, etc., and the quantity is huge.

4. Construction waste

It is divided into remaining concrete, building debris and waste generated by house decoration. Remaining concrete refers to the excess concrete that is not used in the project, and also includes concrete that is not used in time due to suspension of construction for some reason (such as weather changes).

Construction and decoration waste sorting and processing equipment is an advanced technical equipment that can effectively process various waste materials generated during construction and decoration. During the construction process, a large amount of garbage will inevitably be generated, including concrete, stone, glass, ceramics and other materials. These garbage need to be processed and sorted to reduce the impact on the environment, and also provide strong support for resource recycling and reuse. This sorting and processing equipment uses advanced technology and equipment to effectively separate and process different materials in construction and decoration waste.
