From Waste to Energy! Alternative Fuels (SRF/RDF) have played an important role in waste recycling

From an energy structure perspective, Refuse Derived Fuels (RDF)—a promising renewable energy source—have emerged as the fourth-largest energy option for industrial kilns (e.g., cement kilns), ranking only behind coal, petroleum, and natural gas.

As a high-quality and eco-friendly recycled resource, alternative fuels are processed from solid waste.

They offer combustion efficiency comparable to fossil fuels but with significantly lower carbon emissions.

1.4 tons of RDF = 1 ton of coal

1.7 tons of RDF = 1 ton of petroleum coke

2 tons of RDF = 1 ton of fuel oil

Industrial Waste Processing System, which has been designed by Harden Machinery Ltd., adopts a modular design to convert general industrial waste into high-calorific-value alternative fuels (SRF/RDF).

These fuels effectively replace non-renewable fossil energy, enabling the transformation of waste into energy.

For more complex waste compositions, additional equipment such as sorting machines, wind shifter, and optical sorters can be integrated to enhance fuel quality.

The line features Harden’s high-torque dual-shaft shear shredder and a dedicated single-shaft shredder for RDF production.

After secondary shredding, the output achieves a uniform particle size of 30-100 mm, with a compliance rate of up to 95%.

01 Applicable Materials

Commercial waste, waste plastic, leather scraps, waste textile, and other high-calorific-value solid waste.

02 High-Density RDF Particle

Converting industrial waste into Refuse Derived Fuels (RDF) is a proven solution for achieving low-carbon, eco-friendly, and emission-reducing objectives.

As a leader in solid waste recycling, Harden Machinery Ltd. will continue to strengthen R&D, enhance core competencies, and drive innovation in the environmental protection sector.
