The Rise of Small-to-Medium-Sized Decayed Waste Sorting Lines: Unlocking the Resource Value of “Urban Mines”
Release time：2026 / 01 / 14
In tackling the challenge of managing accumulated decayed waste, small-to-medium-sized waste sorting lines with daily processing capacities of 500-1000 tonnes have emerged as core equipment. Through customised design and high adaptability, they provide crucial support for the resource recovery of “urban mines”.
Specifically engineered for the complex composition, high compaction tendencies, corrosive properties, and elevated moisture content of aged waste, these lines feature modular configurations. Core modules can be flexibly combined according to site dimensions and waste composition, ensuring short installation cycles and straightforward future expansion. This design perfectly aligns with the spatial and financial constraints of small-to-medium waste treatment facilities. Core configurations include heavy-duty corrosion-resistant drum screening equipment that vigorously breaks up compacted materials, achieving coarse-fine separation through multi-stage screening. Paired with high-precision corrosion-resistant magnetic separation modules, it accurately separates ferromagnetic metals with recovery rates exceeding 98%. The intelligent air separation system utilises material density differences to separate lightweight combustibles like plastics and paper from inert impurities, achieving overall sorting accuracy surpassing 95%. Furthermore, the waste sorting production line incorporates a fully enclosed working chamber and an efficient deodorisation and dust removal system, controlling odour dispersion and dust pollution at source to eliminate secondary environmental risks. Energy consumption per tonne of waste is maintained at a low level, and operation requires only a small number of specialised personnel, significantly reducing operational costs for small and medium-sized plants.
Leveraging its precise sorting capabilities, the line maximises resource recovery from aged waste: screened humus requires only minor modification for landscaping applications; recovered metals and plastics feed directly into reprocessing supply chains; while high-calorific lightweight combustibles are processed into standardised RDF fuel for stable supply to waste incineration plants. In emerging markets such as Vietnam, these production lines have become the core solution for small and medium-sized sorting plants to overcome waste treatment challenges and enhance profitability, thanks to their high adaptability and cost-effectiveness. They play a vital role in establishing regional solid waste recycling systems.
