In the intelligent garbage sorting and processing line, mixed solid waste such as construction waste and waste furniture will undergo a "technological transformation". For example, the crusher dissociates the material into uniform particles, and the material flows through a three-layer vibrating screening platform - the drum screen is graded according to particle size. The magnetic separator accurately captures metal fragments, and the near-infrared spectrometer instantly recognizes the plastic material. The AI robotic arm then grabs the target object and puts it into the corresponding recycling bin. This integrated multi-dimensional physical screening and artificial intelligence recognition system is being promoted and applied in more than 20 solid waste treatment bases across the country, increasing the waste resource utilization rate to over 95%.
Technological innovation opens up the throat of resource utilization
The pain points of low efficiency and high risk factor in traditional manual sorting are being cracked by intelligent technology. The visual recognition system we developed can distinguish 200 types of garbage, and the robotic arm completes 70 precise grasps per minute, "said the technical director of a domestic environmental protection equipment enterprise. By constructing a full chain sorting system of "particle size screening material identification component extraction", combustibles are converted into alternative fuels (SRF) for energy supply, and metals are directly regenerated in the smelting plant, with an added value of over 150 yuan per ton of waste. According to industry associations, the intelligent sorting line reduces resource recovery costs by 35%, increases incineration heat value by 25%, and reduces carbon dioxide emissions by over 10 million tons annually.

Policy dividends drive industrial upgrading
Under the guidance of the national "14th Five Year Plan" for the development of circular economy, the goal of 60% waste resource utilization rate is accelerating its implementation. The Ministry of Industry and Information Technology has included intelligent sorting equipment in the list of major environmental protection technologies, and multiple departments are jointly promoting the extended producer responsibility system. With the support of policies, the mandatory recycling rate of electronic waste and packaging materials has increased by 30%, and the proportion of recycled aggregates from construction waste replacing natural sand and gravel has exceeded 40%. Screening technology is the core engine of resource utilization, "said an expert from the China Circular Economy Association." With the precision of domestically produced sorting equipment approaching the international level, the industry is developing at an annual growth rate of 15%
Building a new ecosystem of circular economy
The industry predicts that the market size of intelligent sorting will exceed 20 billion yuan by 2025. At a resource recycling base in Jiangsu, screened wood is used to produce biomass pellet fuel, and waste plastics are regenerated into automotive parts raw materials after deep purification. The technological dividend is giving birth to a new business model that integrates resource recycling, green energy, and new material manufacturing, "analyzed a professor from the School of Environment at Tsinghua University. With the continuous iteration of AI algorithms and the large-scale application of equipment, this intelligent sorting path of "putting garbage in its own place" is injecting strong momentum into the construction of "waste free cities".
