Current status and development of demolition waste treatment technology

Preface: New demolition waste treatment technologies continue to emerge, providing more options for the classification and treatment of demolition waste. Although demolition waste treatment technology has made great progress, there are still many shortcomings and defects. The development of demolition waste treatment technology provides energy-saving and environmentally friendly solutions for the treatment of demolition waste.

demolition waste treatment technology is a complex and multidimensional topic, involving policies, economy, society and technology. The following is a detailed analysis by Zhongcheng Machinery Editor:

A. The current status of demolition waste treatment technology

1. Policies and regulations: Many countries have issued policies and regulations on demolition waste treatment, which provide guidance and norms for the treatment of demolition waste. There are still deficiencies in the policies and regulations on demolition waste treatment, especially in the lack of specific requirements and regulations in terms of source reduction, classification and recycling.

2. Classification and recycling: The raw materials of demolition waste are complex, and the industry does not have a unified and clear classification standard, which leads to complex and difficult subsequent sorting and disposal procedures. The classification of demolition waste has not been well implemented, and there are even cases of mixed loading of demolition waste and domestic waste, which increases the cost of treatment.

3. Development of the industrial chain: The industrial chain of the demolition waste treatment industry is not yet sound. From the upstream generation of demolition waste to the downstream recycled product consumption market, there are problems such as information asymmetry, resource imbalance, and price and quality disproportion. The entire industrial chain of demolition waste disposal is imperfect, and the collection, transportation, sorting, and utilization links are disconnected. The generation, resource utilization, and product application of demolition waste have not yet been fully opened.

4. Technology and application: demolition waste treatment technology has made certain progress, such as the gradual maturity of the "pretreatment + multi-stage crushing + graded fine screening + dry/wet switching" technical route. demolition waste recycling products have expanded to recycled aggregates, recycled bricks, blocks, wall panels, floor tiles, recycled concrete and other building materials, and are widely used in road demolition, squares, sidewalks, slow lanes, open squares, gardens, slope protection, foundation protection, highways and overpasses.

B. Development of demolition waste treatment technology

1. Improvement of policies and regulations: It is expected that the industry will introduce more policies and regulations on demolition waste treatment in the future, especially in terms of source reduction, classified recycling and resource utilization, to promote the healthy development of the demolition waste treatment industry.

2. Extension and optimization of the industrial chain: With the continuous advancement of demolition waste treatment technology and the continuous expansion of the recycled product market, the demolition waste treatment industry chain will gradually extend and optimize. It is expected that the future industrial chain will pay more attention to the connection and coordination between upstream and downstream to improve resource utilization efficiency and reduce treatment costs.

3. Innovation and upgrading of technology: The waste treatment technology in the demolition industry will continue to innovate and upgrade to improve treatment efficiency and product quality. The accuracy and efficiency of demolition waste classification can be improved by introducing advanced sorting equipment and technology; the quality and utilization rate of recycled aggregates can be improved by optimizing crushing and screening processes.

4. Market promotion and application: With the improvement of people's environmental awareness and the government's deepening attention to the resource utilization of demolition waste, it is expected that demolition waste recycling products will be more widely used and promoted in the future. The government will increase its support for demolition waste resource utilization products, such as providing financial subsidies, tax incentives and other measures to encourage more companies to participate in demolition waste treatment projects.

5. International cooperation and exchanges: We will strengthen cooperation and exchanges with advanced countries and regions in the world, introduce advanced demolition waste treatment technologies and experiences, and promote the rapid development of demolition waste treatment technologies.

C. Zhongcheng Machinery's demolition waste screening machine has the following advantages:

1. High efficiency: It can quickly classify mixed demolition waste and improve processing speed.

2. Accuracy: By adjusting the gap of the sieve plate, materials of different sizes can be accurately separated to meet different recycling needs.

3. Durability: Due to its fully enclosed design, it can work stably in harsh environments and reduce maintenance costs.

4. Environmental protection: The fully enclosed system effectively prevents the spread of dust and reduces pollution to the environment.

PS: demolition waste treatment technology has made certain progress, but there are still many problems and challenges. In the future, with the improvement of policies and regulations, the extension and optimization of the industrial chain, the innovation and upgrading of technology, and the strengthening of market promotion and application, demolition waste treatment technology will usher in a broader development prospect.
