Standards Development

Scope

This document specifies the general principles and requirements for non-hazardous solid recovered materials (SRM) used in construction works, covering the classification of SRM, material specifications and associated test methods.

Note 1: This document does not cover waste treatment methods, manufacturing processes or construction practices.

Note 2: This document does not apply to hazardous waste or solid recovered fuels (SRF) intended for energy recovery.

Purpose

This document aims to promote the standardized application of non-hazardous solid recovered materials in construction works, in order to achieve environmental, economic and social benefits. The utilization of solid recycled material can reduce waste accumulation, mitigate pollution, conserve natural resources, and protect the ecological environment; it can also lower enterprise costs, improve resource utilization efficiency, advance the circular economy, and enhance market competitiveness; meanwhile, it helps improve public health, create more employment opportunities, promote community relations and social equity, and at the same time facilitate international exchanges and cooperation.

This document provides standardized principles for the classification and testing of solid recovered materials used in construction works. It aims to ensure the quality, safety, and environmental performance of these materials, thereby enhancing confidence among engineers, architects, regulatory authorities, and the public. The principles and requirements outlined in this document are intended to promote the continuous and reliable conversion of waste streams into valuable resources in the built environment.

Justification:

The annual output of non-hazardous solid recovered materials has reached hundreds of millions of tons, and its accumulation volume is constantly increasing, causing serious environmental problems. The recycling and utilization of SRM can not only reduce reliance on natural resources but also promote the development of the circular economy, lower production and disposal costs, and improve the resource utilization efficiency of the construction industry, thereby enhancing market competitiveness.

In addition, the application of solid recovered materials in construction works also brings positive social and economic impacts. It helps improve public health and living conditions, create employment opportunities, strengthen community cohesion, and promote social equity. In terms of international cooperation, the implementation of standardized requirements will provide technical support and application demonstrations for different countries and regions, and enhance the cooperation of the global construction industry in resource recycling and utilization. Therefore, the development of this international standard will promote the green transformation of the global construction industry and facilitate the circular utilization of resources, which will have far-reaching positive impacts on the environment, economy, and society.
