In intelligent sorting and processing lines, mixed solid waste, such as construction waste and used furniture, undergoes a technological transformation. For example, a crusher breaks the material into uniform particles. The material then flows through a three-tiered vibrating screening platform, where a drum screen separates the particles by size. A magnetic separator precisely captures metal fragments, and a near-infrared spectrometer instantly identifies plastic materials. An AI robotic arm then grabs the target object and places it in the appropriate recycling bin. This system, integrating multi-dimensional physical screening with AI recognition, is being implemented in over 20 solid waste treatment bases nationwide, increasing the waste recycling rate to over 95%.

Technological innovation opens up bottlenecks in resource recovery. Intelligent technology is addressing the inefficiencies and risks of traditional manual sorting. "Our developed visual recognition system can distinguish 200 types of waste, and the robotic arm performs 70 precise grabs per minute," explained the technical director of a domestic environmental protection equipment company. By building a comprehensive sorting system encompassing particle size screening, material identification, and component extraction, combustibles are converted into alternative fuels (SRF) for energy, and metals are directly recycled in smelters, generating over 150 yuan in added value per ton of waste. According to industry association estimates, the intelligent sorting line has reduced resource recovery costs by 35%, increased incineration calorific value by 25%, and reduced annual carbon dioxide emissions by over 10 million tons.

Policy dividends drive industrial upgrading

The goal of a 60% waste resource recovery rate is accelerating. Intelligent sorting equipment has been included in the catalog of major environmental protection technologies, and multiple departments are jointly promoting the extended producer responsibility system. Thanks to policy support, the mandatory recycling rate for electronic waste and packaging has increased by 30%, and the proportion of recycled aggregate from construction waste replacing natural sand and gravel has exceeded 40%. "Screening technology is the core engine of resource utilization." "As the accuracy of domestic sorting equipment approaches international standards, the industry is growing at an annual rate of 15%."

Building a new circular economy ecosystem

Screened wood is made into biomass pellet fuel, and waste plastics are reborn as raw materials for automotive parts after deep purification. "Technological dividends are spurring new business models that integrate resource recycling, green energy, and new materials manufacturing." With the continuous iteration of AI algorithms and the large-scale application of equipment, this intelligent sorting path that "puts waste in its proper place" is injecting strong momentum into the construction of "zero-waste cities."
