Research on the Management and Countermeasures of Urban Construction Waste: A Case Study of Yiyang

Abstract

The management of construction waste has become one of the major problems in urban management in China. This paper conducts a comparative analysis of the management models of urban construction waste in developed foreign countries, identifies the problems and gaps in the management of construction waste in Yiyang compared with other regions, and thus proposes scientific countermeasures and suggestions for dealing with construction waste in Yiyang.

Introduction

Summary:

China is experiencing rapid urbanization, leading to a sharp increase in construction waste, which poses significant environmental and management challenges. Much of this waste is disposed of by open-air stacking or landfilling, causing land use issues and ecological damage. This paper explores effective urban construction waste management suited to China’s context through comparison and empirical research.

Definition:
Construction waste includes debris from building construction, renovation, expansion, demolition, and household decoration, primarily solid waste like concrete, asphalt, bricks, and mortar.

International Practices:

• USA: Generates 325 million tons of construction waste yearly; 70% recycled.

• Singapore: 98% processed, 50-60% recycled; strict policies regulate disposal.

• Japan: Focuses on minimizing waste generation and on-site reuse due to limited land.

Lessons for China:

• Prioritize waste reduction at the source and recycling.

• Maintain and renovate existing buildings to extend life and reduce demolition waste.

• Develop industrial-scale recycling industries for construction waste.

• Enforce strict government supervision and penalties.

Case Study – Yiyang City:

• Construction waste is rapidly increasing (approx. 30 million cubic meters/year).

• The waste removal market is disorganized due to lack of government coordination.

• Recycling efforts are limited, with mostly small-scale enterprises relying on landfill disposal.

• Management systems are unclear, leading to weak supervision.

Proposed Countermeasures for Yiyang:

• Emphasize reducing waste generation via better materials and construction methods.

• Treat construction waste as a renewable resource, encouraging reuse and recycling.

• Implement intensive government-led waste removal, with costs borne by waste generators.

• Adopt a management model combining government leadership with market participation and oversee the entire process from generation to disposal.

• Promote new technologies and social investment to improve recycling and environmental protection.

Conclusion

In conclusion, the management of urban construction waste in Yiyang should first require construction enterprises to carry out clean production to achieve the goal of \"reduction\" and reduce the generation of construction waste from the source. For the generated construction waste, adhere to the whole - process management. The government departments, enterprises, and the public should strengthen cooperation to ensure that each link is under strict supervision. Formulate norms for the recycling of construction waste and give certain support to recycling enterprises to increase the proportion of recycling.
