Decorative Waste Sorting and Treatment

Decorative waste, also known as construction waste or demolition waste, refers to various types of waste generated during the construction, repair, and demolition of buildings. This type of waste typically includes materials such as concrete blocks, bricks and stones, wood, metal, plastic, glass, and gypsum board. Due to the large volume and complex composition of decorative waste, proper sorting and treatment are of great significance for environmental protection and resource recycling.

The Importance of Sorting and Treatment

1. Resource Recycling: Sorting can separate recyclable materials such as metal, wood, and plastic, achieving the reuse of resources.

2. Reduction of Environmental Pollution: Proper handling of decorative waste can prevent pollution from harmful substances, protecting soil and water sources from contamination.

3. Saving Landfill Space: The volume of non-recyclable waste after sorting will be greatly reduced, helping to save limited landfill space.

4. Promoting Circular Economy: Effective management of decorative waste is one of the key steps in promoting the transformation of the construction industry towards a circular economy.

Methods of Sorting and Treatment

1. Source Sorting: During the generation of decorative waste, preliminary sorting should be done according to the type of material, such as piling wood, metal, concrete, etc., separately.

2. Professional Sorting Centers: After collecting a certain amount, transport it to professional sorting centers for more detailed classification. These centers are equipped with various mechanical equipment, such as crushers, magnetic separators, etc., which can efficiently complete the sorting work.

3. Resource Utilization: Recyclable materials sorted out, such as metal and plastic, can be directly sold to related recycling enterprises; while materials that are difficult to reuse directly, like concrete and bricks, can be crushed and processed into recycled building material raw materials.

4. Harmless Disposal: For those wastes that cannot be recycled and utilized, harmless treatment measures need to be taken, such as incineration for power generation or safe landfilling, to ensure that they do not have a negative impact on the environment.
