LFW(Landfill Waste) Management System

This facility converts municipal solid waste (MSW) from landfills or excavated landfill waste into Refuse-Derived Fuel (RDF) through mechanical processes such as sorting, shredding, drying, and compressing. It contributes to both landfill volume reduction and energy recovery, offering a sustainable solution for waste management. Key processes include shredding, metal/non-metal separation, drying, and pelletizing.

Applications of RDF – Cement Plants and Power Plants

Refuse-Derived Fuel (RDF) is used as an alternative fuel to replace fossil fuels such as coal and heavy oil. Its main applications include cement plants and power generation facilities.

• In cement plants, RDF is utilized as a secondary fuel in kilns to reduce coal consumption and lower greenhouse gas emissions. The residual ash after combustion can also be reused as a raw material for cement.
• In power plants, RDF is burned to generate electricity or used as a heat source in steam boilers. This supports waste-to-energy initiatives while contributing to the production of electricity and thermal energy.

Key Features of RDF Production Facility for Landfilled Waste

The RDF production facility for landfilled waste is an integrated treatment system that mechanically recovers and converts previously buried or semi-decomposed municipal solid waste into Refuse-Derived Fuel (RDF). The system includes processes such as sorting, shredding, drying, impurity removal, and fuel shaping. It efficiently separates recyclable and combustible components from landfill waste and transforms them into valuable energy resources. This facility helps reduce the occupied volume of landfills, prevents long-term environmental pollution, and lowers the burden of post-closure landfill management. Moreover, the system is specially designed to handle landfill waste with high moisture and contamination levels, ensuring stable operation under various site conditions.

Reference Specification

RDF Production Facility for 500 TPD of Landfilled Waste (Excluding Pelletizer, with Optional Units)

The RDF production facility designed for processing 500 tons per day of landfilled waste includes key systems for waste pretreatment and fuel conversion. The process begins with a primary shredder, which breaks down bulky waste. A vibrating screen then separates particles smaller than 50mm, followed by magnetic and eddy current separators for removal of ferrous and non-ferrous metals. A wind-based air separator is used to extract light combustible fractions suitable for RDF.

Subsequently, a secondary shredder reduces the material to an ideal size (below 30–40mm), and a rotary dryer is installed to reduce moisture content from approximately 40% to less than 15%, enabling efficient combustion of the RDF.

※ Equipment installed after the rotary dryer is optional.

• A deodorization system may be added to remove odor-causing compounds (e.g., H₂S, ammonia), minimizing environmental impact.
• A dust collection system helps control fine particulates, improving worker safety and air quality.
• A PLC-based central control panel enables automated operation and remote monitoring, ensuring efficient and safe management of the entire process.
  These optional systems can be included depending on the characteristics of the waste and the conditions of the project site.
