The Treatment of Construction Waste Is an Important Aspect of Urbanization. How to Handle Construction Waste Efficiently and Environmentally Friendly Has Become a Significant Issue. Construction waste mainly includes materials such as concrete, bricks, metals, wood, and plastics. Below are some commonly used methods for treating construction waste and their development trends.

 

Construction Waste Treatment Equipment

 

I. On - Site Sorting and Recycling

 

At construction sites, temporary sorting areas are set up to carry out preliminary sorting of generated construction waste. For example, metal waste such as rebar and copper wire is separated from non - metal waste; for discarded wood in good condition, it can be reused in other projects or processed into wood - based composite materials. This method not only reduces transportation costs but also facilitates subsequent treatment.

 

II. Centralized Treatment

 

1. Crushing and Screening  

   - Discarded concrete and bricks can be processed through specialized machinery for crushing and screening, transforming them into recycled aggregates of various particle sizes. These recycled aggregates can be used to produce new building materials, such as recycled concrete and bricks.

 

2. Metal Recycling  

   - Ferrous metals like steel can be separated from construction waste using magnetic separators, and non - ferrous metals (such as copper and aluminum) can be recovered through other means. The recycled metals can then be sent back to smelters for reprocessing into new metal products.

 

3. Wood and Plastic Processing  

   - Wood can be shredded for biomass energy production or turned into wood - plastic composite materials. Plastics can be recycled through chemical or physical methods to create new plastic products or for other uses.

 

III. Landfilling and Incineration

 

Although we encourage reducing the proportion of direct landfilling and incineration, these methods are still necessary in some cases. However, modern landfills use anti - seepage technology to minimize groundwater pollution and install biogas collection systems to utilize the gases produced during waste decomposition. In terms of incineration, advanced combustion techniques and exhaust gas purification devices can effectively reduce pollutant emissions.

 

IV. Innovation and Technological Development

 

In recent years, with technological advancements, some new - type treatment technologies have gradually been applied to the handling of construction waste. For example, the use of microbial degradation technology to process hard - to - recycle organic waste, or the application of 3D printing technology to directly manufacture needed building components from recycled materials.

 

The treatment of construction waste is moving towards a more environmentally friendly and efficient direction. Through scientific and rational sorting, recycling, and reuse, as well as necessary landfilling and incineration, we can not only reduce the pressure on the environment but also maximize the utilization of resources and promote the achievement of sustainable development goals. In the future, further efforts are needed to strengthen technological research and development, raise public environmental awareness, and jointly drive the progress and development of the construction waste treatment industry.
