Current situation of resource utilization of decoration waste

The on-site situation and composition of decoration waste:

1. The bagging rate of decoration waste is high when it is transported in;

2. The phenomenon of front-end mixed loading and transportation is serious, and even contains garden waste;

3. High content of bamboo wood and lightweight building blocks (lightweight materials);

4. Mixed with some household waste, scrap metal, and asbestos;

5. It also contains a certain amount of toxic and harmful substances;

6. In addition, it was found that the content of soil in decoration waste is particularly prominent.

The composition is extremely complex and the proportion fluctuates greatly. The main influencing factors are as follows:

1. Local source classification and sorting management methods;

2. Operation path or mode;

3. House structure;

4. The degree of newness of the decorated house;

5. Unit or individual decoration preferences, etc;

6. Local cultural literacy;

7. The materials used in decoration are constantly changing.

Overall, the composition of decoration waste is extremely complex and volatile, and the differentiated management forms in the front-end further increase the complexity of its composition; Implementing front-end sorting and control of decoration waste is currently the most urgent and economical resource utilization mode.
