What is AFR / RDF?
AFR (Alternative Fuel & Raw Material)
AFR refers to waste-derived materials that can be used as fuel or a raw material substitute in cement and industrial production processes.
RDF (Refuse-Derived Fuel)
RDF is produced from combustible fractions of municipal and industrial waste such as plastics, paper, textiles, rubber, wood, and packaging material.
These fuels help reduce carbon emissions and minimize landfill waste while generating economic value from waste materials.
AFR / RDF Processing Plant Working Principle
The plant processes mixed waste through multiple stages, such as shredding, screening, metal separation, density separation, and size reduction to produce high-calorific alternative fuel suitable for industrial combustion.
Process Flow of AFR / RDF Plant
Stage 1 – Waste Feeding
Municipal solid waste, industrial waste, commercial waste, plastic waste, and packaging waste are fed into the plant using conveyor systems or loaders.
- Industrial waste
- Plastic waste
- Paper & cardboard
- Textile waste
- Rubber waste
- Packaging waste
Primary Shredding
Waste material is reduced into smaller pieces (50–150 mm) using a high-torque shredder. This ensures uniform size for further processing and efficient separation.
Screening Process
Screening equipment separates fine particles and oversized materials to achieve a consistent particle size suitable for fuel production.
- Improve fuel quality
- Maintain uniform particle size
Magnetic Separation
Ferrous metals are removed using overband magnetic separators to protect downstream equipment and improve fuel purity. Output:
Clean combustible material- Recovered metal scrap
Air Separation / Density Separation
Air classifiers or wind sifters separate heavy materials such as stones, glass, and metals from light combustible materials like plastic film, paper, and textiles.
Secondary Shredding
Material is further reduced into a smaller size (20–80 mm) suitable for use as RDF fuel in cement kilns or industrial furnaces.
Final RDF Storage
Processed fuel is stored in bunkers, silos, or jumbo bags for transportation to cement plants, power plants, or industrial boilers. Final Output:
- Recovered metals
- Recovered metals
RDF can be used as a substitute fuel in cement kilns, reducing coal consumption and greenhouse gas emissions.
Input Materials for AFR / RDF Plant
The plant can process a wide variety of waste materials:
- Municipal solid waste (MSW)
- Commercial waste
- Industrial waste
- Plastic waste
- Paper & cardboard
- Textile waste
- Packaging material
- Wood waste
- Rubber waste
Material composition can be customized based on fuel requirements.

FAQs
RDF is fuel produced from combustible waste materials such as plastic, paper, textiles, and packaging waste.
RDF fuel is mainly used in cement plants, power plants, and industrial furnaces.
Typically ranges from 2500 to 4500 kcal/kg depending on waste composition.
