April 2, 2025 – As urbanization accelerates, the issue of mixed renovation waste generated from decoration activities has become increasingly prominent. The sheer volume and complex composition of this waste pose significant environmental risks if not handled properly. However, the emergence of a sorting and resource recovery production line for mixed renovation waste offers an innovative solution, spearheading a green revolution.
Renovation waste typically contains a variety of materials such as wood, metal, and plastic. Traditional disposal methods like landfilling or incineration not only waste resources but also potentially contaminate soil, groundwater, and the atmosphere. The objective of the resource recovery sorting line is to transform this waste into valuable reusable resources.
On this efficient production line, renovation waste first undergoes a pretreatment phase where large crushers break down bulky items into smaller particles for easier processing. Subsequently, magnetic separators extract ferromagnetic metals, which are directly recycled into the steel production cycle. According to the Color Masterbatch Industry Network, this step not only boosts resource recovery rates but also simplifies waste management.
Next is the screening process, where waste is separated into different fractions using screens with varying apertures. Coarse materials like bricks and ceramic fragments can be further processed into recycled bricks and aggregates. Fine materials such as plastics and paper are further separated through air classification and density separation. Air classification technology lifts lightweight plastic particles and paper, while electrostatic separation sorts plastics based on their conductivity, ensuring precise resource recovery.
The separated plastics, after cleaning and crushing, are transformed into recycled plastic pellets for use in various plastic products. Paper and fabrics are compressed and packaged as raw materials for papermaking or industrial wiping cloths. The entire production line is equipped with an automated control system, utilizing smart sensors and data analysis to monitor operational status in real-time, optimizing sorting efficiency and effectiveness.
This production line brings notable environmental benefits, reducing landfill volume and greenhouse gas emissions while improving air quality. It also offers economic advantages to businesses by lowering raw material procurement costs, with government support policies providing subsidies and tax incentives.
Moreover, the promotion and application of this production line have enhanced public awareness of environmental protection. Communities and construction sites are more actively participating in waste sorting and transportation, fostering a positive environmental atmosphere. The mixed renovation waste sorting and resource recovery production line has become a cornerstone of urban green development, leading us towards a more sustainable future.
