Mixed municipal solid waste contains a significant amount of recyclable materials, such as beverage bottles, metals, and cardboard, which can be recovered and reused.

Additionally，organic waste (40-60% of MSW): Can be converted into bio-energy.

High-calorific combustibles (largest proportion): Can be processed into Solid Recovered Fuel (SRF/RDF) as a sustainable alternative to coal, reducing carbon emissions while maintaining comparable combustion efficiency.

SRF/RDF represents an innovative approach to waste reduction, non-hazardous treatment, and resource recovery, offering an eco-friendly and cost-effective fuel alternative for a circular economy.

How is Solid Recovered Fuel (SRF) Produced?

As a leading solid waste pre-processing equipment provider with over a decade of expertise, HARDEN MACHINERY LTD. delivers integrated and reliable SRF production systems tailored for: Recyclable sorting, Organic material extraction,RDF/SRF fuel production.

Our systems are widely implemented in MSW transfer stations, recycling centers, and cement manufacturing plants globally.

SRF Production Process:

Primary Shredding: MSW is coarsely shredded.

Refinement: The shredded material undergoes screening, magnetic separation, and air classification to recover metals, light fractions, and heavy residues.

Secondary Shredding: Light fractions are finely shredded into high-quality SRF, with 98% of particles sized below 30–80mm.

Through continuous innovation, HARDEN supports the transition toward waste reduction, non-hazardous treatment, and sustainable resource recovery.
