Resource Utilization of Construction Waste

With the acceleration of urbanization, the generation of construction waste is increasing day by day, becoming one of the important factors affecting environmental quality. Effectively promoting the resource utilization of construction waste not only helps to alleviate land pressure but also promotes the development of the circular economy. This article will start from the classification of sources to discuss how to improve the quality of resource utilization of construction waste.

I. Define Classification Standards and Refine Recycling Processes

Construction waste is mainly divided into four major categories: engineering soil, demolition waste, construction waste, and renovation waste. Among them, concrete and masonry, as well as soil and ash mixtures, dominate, accounting for about 70%-80% of the total volume. In light of this characteristic, preliminary sorting should be strictly carried out according to categories during the collection phase to ensure that valuable components can be extracted more efficiently in subsequent treatment processes.

II. Technological Innovation Drives Efficiency Improvement

1. Application of Intelligent Sorting Equipment: Utilize advanced technologies such as photoelectric sensors and artificial intelligence algorithms to accurately identify and separate different substances in complex mixtures, reducing errors caused by human intervention.

2. Development of New Materials: Encourage cooperation between research institutions and enterprises to develop high-performance recycled products suitable for specific scenarios, such as high-strength permeable bricks and lightweight insulation panels, to expand the application field.

3. Process Optimization and Upgrade: Continuously improve the technical equipment level of key processes such as crushing, screening, and washing, reducing energy consumption while ensuring stable product quality.

III. Improve the Policy and Regulatory System

The government should issue more detailed guiding documents to clarify the responsibilities and obligations of all parties; and support through financial subsidies, tax incentives, and other means to stimulate the enthusiasm of market entities; establish and improve regulatory mechanisms, severely crack down on illegal dumping behavior, and create a fair competitive market environment.

In summary, by scientifically and reasonably planning and deploying, increasing investment in scientific and technological research and development, and strengthening the guiding role of policies, we can effectively promote the transformation of construction waste into high-quality resources, contributing to the realization of green development goals.
