As more localities in China pursue zero landfilling of untreated municipal solid waste, improving resource recovery and reducing disposal expenditure while ensuring environmentally sound treatment has become an important challenge for local waste management. Local Zero-Landfill Initiatives
The Ecological and Environmental Code of the People’s Republic of China provides for municipal solid waste reduction and resource recovery, including the recovery of low-value recyclables. The State Council’s Action Plan for the Comprehensive Management of Solid Waste further calls for improved waste sorting and resource recovery, and greater integration of municipal waste collection and recyclable material collection networks.

Transporting mixed municipal solid waste directly to incineration facilities presents three challenges.
First, the material value of recyclables is not fully recovered. When plastics, films and other materials suitable for recycling enter the incineration process, their value as recycling feedstock is difficult to preserve. Waste-to-energy recovers energy, while material recovery provides another pathway for utilizing recyclables.
Second, transportation and treatment costs continue to accrue. Recyclables transported and incinerated alongside other waste also incur associated charges. For projects billed according to the actual quantity of waste processed, insufficient resource recovery means more material is subject to treatment charges.
Third, pollution control requires continued investment. Incineration requires flue-gas cleaning and appropriate management of bottom ash and fly ash, involving treatment chemicals, facility operations and environmental monitoring. Treatment costs do not end when waste enters the incinerator. Environmental Requirements for Waste Incineration Projects
Therefore, waste reduction lowers the quantity requiring paid treatment, while resource recovery directs recyclables into the recycling value chain. Integrating upstream recovery with final treatment helps improve both resource efficiency and the economics of waste management.
Recovering low-value recyclables is challenging because materials are mixed, manual sorting is inefficient, and the recovered material value may not cover sorting costs.
Databeyond integrates intelligent sorting into municipal solid waste transfer stations. By combining AI-powered hyperspectral optical sorters with embodied waste-sorting robots, the system identifies, separates and recovers recyclables from mixed waste. The remaining waste is then sent for final treatment.
This approach adds resource recovery to existing waste collection and transportation processes, providing a technical pathway to reduce the quantity sent for incineration and improve the utilization of low-value recyclables.
The mixed municipal solid waste AI sorting line jointly developed by Databeyond and Dongshi Environment in Liaobu, Dongguan, provides a practical example of this approach.
According to project documentation, the line can complete full-stream automated sorting of 50 tonnes of municipal solid waste within four hours, with no direct manual work required in the sorting stage, achieving approximately 35% waste reduction and 25% resource recovery.
Recovered PE and PP films can be used for pellet production or conversion into oil, while other recovered plastics and metals can be sold as recycling feedstock. By connecting sorting with downstream utilization, some materials previously destined for incineration become usable resources.
Intelligent sorting creates economic value in two ways: reducing the quantity sent for incineration lowers associated transportation and incineration charges billed per tonne; recovering usable materials generates sales revenue to support project operations.
Assuming a daily intake of 1,000 tonnes, 365 operating days per year and three consecutive years of operation, a 25% resource recovery rate would yield approximately 250 tonnes of recovered materials per day, or approximately 274,000 tonnes over three years. Actual savings for local government budgets and net operating earnings must be calculated based on billing arrangements, equipment investment, operating costs, recovered-material prices and contractual terms.
Drawing on its municipal solid waste data, intelligent sorting equipment development and experience in delivering complete sorting lines, Databeyond can provide site surveys, process design, equipment supply, installation and commissioning, operations and after-sales support. Solutions are tailored to local waste composition, processing capacity and downstream recycling channels, offering a replicable approach to reducing costs and increasing revenue from municipal solid waste treatment.
