China generates over 11 billion tons of solid waste annually, covering various categories such as industrial waste, household waste, construction waste, and agricultural straw. This' urban mine 'holds enormous value: rare metals can be extracted from industrial solid waste, the replacement rate of recycled aggregates from construction waste exceeds 50%, and if 30% of the recyclable materials in household waste are fully utilized, 200 million tons of primary resources can be saved annually, with a potential economic value of trillions of yuan.

Key Path to Problem Solving

Intelligent classification system

46 key cities have established garbage classification systems, and Shanghai has deployed 23000 AI recognition garbage bins, resulting in a 40% increase in sorting efficiency for recyclable materials. The Ministry of Housing and Urban Rural Development plans to achieve full coverage of prefecture level cities by 2025, with over 100000 supporting recycling stations for renewable resources.

Technological breakthroughs in industrialization

Zhejiang construction waste crushing line achieves a 95% aggregate regeneration rate; The anaerobic fermentation project for kitchen waste in Beijing produces 50 million cubic meters of biogas annually; The first steel tailings extraction rare earth production line has landed in Baotou, with a rare metal recovery rate exceeding 85%.

Dual drive of policy and industry

Tax incentives: Resource based enterprises enjoy the "three exemptions and three reductions" of income tax

Agglomeration of industrial parks: Tianjin Ziya Circular Economy Zone processes 1.5 million tons of solid waste annually, with an output value of 12 billion yuan

Compulsory procurement: The proportion of recycled building materials used in government projects shall not be less than 30%

Triple benefits highlighted

▶  Environmental Burden Reduction: By 2022, resource utilization will reduce landfill land by 450000 acres and reduce carbon emissions by 120 million tons

▶  Economic hematopoiesis: The renewable resources industry absorbs 5 million jobs, and Shandong Quanlin Paper's straw pulping technology drives farmers to increase their annual income by 300 million yuan

▶  Resource Recycling: Baowu Steel Slag Paving Technology Saves 80 Million Tons of Natural Stone per Year

With the deepening implementation of the "14th Five Year Plan" for the development of circular economy, the utilization rate of solid waste resources will reach 60% by 2025. The Ministry of Industry and Information Technology has launched the "Renewable Raw Material Substitution Action" and plans to cultivate 100 benchmark enterprises to truly transform solid waste from an "ecological burden" into a "green mineral deposit" supporting the beautiful China.
