The report pointed out: At present, the complexity, severity and uncertainty of the international environment have increased significantly, and all countries are changing their development methods, which will have an important impact on the future development of the sand and gravel and equipment industries. Adhering to resource recycling and creating a multi-level, three-dimensional and efficient resource utilization system is the only way for the sand and gravel and equipment industries to cultivate sustainable competitiveness and achieve green, low-carbon and high-quality development.
Reports include "Modern Environmental Pollution", "Main Documents on Comprehensive Utilization of Domestic Solid Waste", "Comprehensive Utilization of Construction Solid Waste in Several Countries and Regions", "Comprehensive Utilization of Solid Waste Products and Environmental Restoration of Domestic and Foreign Solid Waste", "Solid Waste Utilization and Mining Ecology In terms of restoration model, "issues that solid waste comprehensive utilization enterprises must pay attention to", the development status, challenges and response strategies of the sand and gravel industry in the fields of solid waste resource utilization and ecological environment restoration were analyzed and elaborated.
The report focuses on the comprehensive utilization model of construction solid waste, mining solid waste, road construction hole slag, etc., the prominent problems in the resource utilization of construction solid waste and the application industry chain, construction solid waste disposal and utilization, and the comprehensive utilization of mechanism sand and gravel by-products. Its precautions and product application areas, ecological restoration model of abandoned mines, increase carbon sink capacity through afforestation, and achieve carbon neutrality.

The report pointed out that China has a large inventory of solid waste, tailings and waste stone. The inventory of construction solid waste is more than 20 billion tons, and the cumulative inventory of solid waste such as tailings and waste stone is more than 60 billion tons. In response to this, China has issued the "Work Plan for the Pilot Promotion of the Construction of "Waste-free City"" in recent years, "Several Opinions on Promoting the High-Quality Development of the Mechanized Sand and Gravel Industry", "Letter on the Construction of a Green Building Sand and Gravel Base", "On the "10th" Guiding Opinions on Comprehensive Utilization of Bulk Solid Waste in the Fourth Five-Year Plan", "The 14th Five-Year Plan for Circular Economy Development", "The 14th Five-Year Plan for Industrial Green Development", "The 14th Five-Year Plan for Construction of "Waste-free City" in the "14th Five-Year Plan" Period 》 《Notice on Accelerating the Demonstration Construction of Comprehensive Utilization of Bulk Solid Waste", 《Implementation Plan on Accelerating the Comprehensive Utilization of Industrial Resources", "Guidelines for the Construction of Carbon Peak and Carbon Neutral Standard System", etc., to accelerate the construction of waste materials circulation Utilize system construction. Although China's solid waste recycling and utilization has accelerated in recent years, the standards and specifications are not yet sound and the application areas need to be clarified.

The report provides a detailed introduction to the current status of the industry in the comprehensive utilization and environmental restoration of solid waste in the United States, Germany, the United Kingdom, Sweden, the Netherlands, Italy, Spain, France and other countries, as well as the main methods of comprehensive utilization.
