In recent years, with the rise of waste sorting and recycling, the treatment and recycling of construction waste has become an area of ​​great potential. We have proposed a series of construction waste recycling methods, which are outlined below:

Reusing old wood and sawdust

Old wood and sawdust can be reused directly as building materials or processed into composite panels.

These materials can also be used as fuel or compost, and in erosion control projects.

Recycling bricks and tiles

Bricks from demolished buildings can be processed into unburned bricks for use as cement aggregate in foundation projects, or re-fired into hollow bricks for use as cement raw materials.

Recycling asphalt

Sorted asphalt can be recycled and used as road paving material.

Recycling concrete

As a major component of construction waste, concrete has a high recycling value.

Concrete can be crushed into powder and used as an additive or filler.

The technology for recycling old concrete is relatively mature, primarily used to produce recycled concrete and recycled cement.

This recycling method helps conserve resources such as limestone, natural stone, and iron powder, while also reducing coal combustion.

Resource Utilization of Fine Powder

Further refinement and utilization of fine powder from construction waste can increase the value of recycled materials and enhance the overall efficiency of resource utilization.

If fine powder is not processed, the recycling efficiency of construction waste will be reduced and may cause environmental pollution.

By studying the composition and physical properties of ground mineral admixtures from waste concrete and broken bricks, it is possible to add an appropriate amount of fine powder to cement to improve its performance.

These methods not only help reduce the environmental impact of construction waste but also improve economic benefits through resource reuse. With technological advancements and growing awareness of environmental issues, the resource utilization of construction waste will become increasingly important.
