3.4 Reuse

Appropriate physical or mechanical processing of recycled waste wood-based panels, or simple repairs, repairs, and refurbishment. use.

Note: For example, the usable part of the abandoned building wooden beams and purlins can be directly processed into furniture parts, and the discarded large pieces of plywood are cut into small pieces for continued use.

3.5 Regenerative utilization

Use waste wood-based panels as raw materials to produce or manufacture new materials.

Note: Such as waste wood production of artificial panels, waste wood liquefaction, carbon material manufacturing, etc.

6.1 Recycling

Follow the principles of proximity, classification, safety, and environmental protection, and recycle from consumers or users of wood products, or use waste materials Recycle bin (point) for recycling.

6.2 Sorting

The recycled waste wood-based panels can be classified according to the classification method in 5.2 and the requirements of downstream enterprises, according to the type of raw material, the shape of the raw material, and the raw material The specifications are disassembled and sorted.

7.1 Storage

7.1.1 Waste wood-based panels should be stored separately.

7.1.2 The storage of waste wood-based panels should be fireproof, waterproof, anticorrosive, anti-spreading, anti-loss, anti-leakage and other measures to prevent environmental pollution. The measures should comply with the relevant national solid waste pollution control standards.

7.1.3 The waste wood-based panels treated with anti-corrosion or flame-retardant treatment should be properly covered to prevent the degradation and loss of chemical substances caused by wind and rain.

7.1.4 Contains the substances listed in the "List of Hazardous Chemicals" and "National Hazardous Waste List", and contains "The People's Republic of China Entry Plant Quarantine Waste wood-based panels of harmful organisms listed in the "List of Sexual Pests" and "National Forestry Quarantine Pests List" should be equipped with hazardous waste The storage facilities shall be provided with waste identification signs and shall be promptly sent to a qualified hazardous solid waste treatment unit for disposal.

7.2 Transportation

7.2.1 During transportation, waste wood-based panels should be properly covered and reinforced, and should not be discarded or scattered along the way.

7.2.2 When transferring hazardous waste wood-based panels, the hazardous waste transfer form should be filled in in accordance with relevant national regulations and transferred to hazardous waste. Report from the environmental protection administrative department of the local people's government at or above the county level in the place of origin and the place of acceptance.

8.1 How to use

8.1.1 A and B types of waste wood-based panels shall follow the sequence of reuse, recycling, and energy utilization.

8.1.2 Class C waste wood-based panels can be recycled and used as energy sources.

8.1.3 Class D waste wood-based panels generally only use energy, and can also be used as an additive material for anti-corrosion, flame-retardant, and insect-proof wood-based panels.

8.1.4 E-class waste wood-based panels should be disposed of in accordance with relevant national solid waste disposal regulations.

8.1.5 Type F waste man-made panels shall be carried out in accordance with the "Plant Quarantine Regulations of the People's Republic of China" and "Technical Regulations for Forest Plant Quarantine" deal with.

8.2 Reuse

The recycled waste and old building wood-based panel templates, wood-based panel pallets, wood composite flooring, wood-based panel furniture, etc. should be reused first.

8.3 Recycling

8.3.1 Manufacturing wood-based panels

Recycled waste wood-based panels can be used to produce wood-based panels such as fiberboard and particle board.

8.3.2 Manufacturing wood-plastic composite materials

The recycled waste wood-based panels can be combined with plastics to produce wood-plastic composite materials after processing.

8.3.3 Manufacture of biodegradable molded products

Process the recycled waste man-made board into fine powder, mix it with biodegradable adhesive, and press it into various types of biodegradable Craft products and practical products.

8.3.4 Manufacturing inorganic wood composite materials

The recycled waste man-made boards can be processed to produce cement-based man-made boards, gypsum man-made boards and other inorganic wood composite materials.

8.3.5 Wood chemical processing products

Class A waste wood-based panels can be processed by hydrolysis, pyrolysis and liquefaction to produce aldehyde and its derivatives, acetic acid, wood tar anti-polymerization agent, charcoal, living Various products such as sex charcoal.

8.4 Energy utilization

Class A, B, C and D waste wood-based panels can be incinerated as energy raw materials directly or after processing.

8.5 Special treatment

In principle, E and F waste wood-based panels should be sent to a qualified hazardous solid waste disposal agency for disposal.
