Primary Shredders: The Backbone of Solid Waste Pre-Treatment
In the full cycle of solid waste resource recovery, pre-treatment is the linchpin that shapes the efficiency and value of all downstream processes.At the forefront of this stage stand primary two-shaft shredders—the machines that take on the toughest materials and lay the groundwork for effective recovery.2025-10-30 -

From Waste to Fuel: Harden's RDF Systems Unlock Value in C&D Waste
Construction and demolition (C&D) waste represents a massive opportunity in the global push for resource recovery, with lightweight combustibles often overlooked as a source of high-value refuse-derived fuel (RDF).2025-10-29 -

Scaling EV Battery Recycling: Shredding Innovations Drive the Global Lithium Resource Recovery
The electric vehicle (EV) revolution is accelerating worldwide, but with it comes a tidal wave of retired lithium-ion batteries. Globally, end-of-life EV batteries are projected to exceed 500 GWh by 2030, according to the International Energy Agency (IEA), fueling a recycling market valued at over $20 billion annually.2025-10-24 -

MSW to AFR: Harden Powers Southeast Asia's Waste-to-Energy Shift
MSW harbors untapped energy potential: combustibles like plastics, paper, and textiles comprise over 40% of typical streams, convertible into stable alternative fuels and raw materials (AFR)—or RDF/SRF—with calorific values surpassing 3,000 kcal/kg, equivalent to 60% of standard coal2025-10-22 -

Precision at 20mm: Harden's Advanced Shredding Unlocks Scalable Plastic Recycling
Uneven particle sizes and lingering impurities from coarse shredding undermine reaction efficiency, inflate energy demands, and hinder the industrialization of plastic recovery. Harden Machinery Ltd. addresses this critical gap with its precision shredding technology, delivering uniform 20mm outputs that serve as the ideal precursor for downstream chemical processes.2025-10-20 -

RDF vs. Coal in Cement Kilns: How 10 Tons of RDF Delivers Equivalent Heat from 6.5–7.5 Tons of Coal
In the cement industry's quest for carbon neutrality, Refuse-Derived Fuel (RDF) stands out as a dual-purpose powerhouse: it diverts solid waste from landfills while substituting fossil fuels in energy-intensive kilns. For many operators, the burning question is simple: in a cement kiln, how much coal does 10 tons of RDF replace? Harden Machinery Ltd. breaks it down using key metrics—calorific value, thermal efficiency, and thermal substitution rate (TSR)—to show the real-world impact.2025-10-10 -

Harden Machinery Powers 100,000-Ton RDF Production Line for Cement Industry Transformation
In Zhongshan, China, a leading cement company has launched a 100,000-ton RDF production line, turning mixed industrial waste into high-quality Refuse-Derived Fuel (RDF). Partnering with Harden Machinery Ltd., this facility is driving the cement industry’s shift toward a circular economy and sustainable production.2025-09-26 -

RDF Powers the Cement Industry Toward a Sustainable Future
As the world rallies to tackle climate change and champion green growth, the cement industry— notorious for its hefty energy use and emissions—stands at a crossroads of challenges and opportunities. Many cement giants are now embracing RDF (Refuse-Derived Fuel) as a game-changing alternative, but what is it, and how does it shine in cement production? Let’s uncover the answers!2025-09-23 -

Optimal RDF Particle Size for Cement Kilns: Maximizing Efficiency in Waste-to-Energy
In the push toward carbon neutrality and circular economy principles, Refuse-Derived Fuel (RDF) has become a cornerstone for the cement industry, turning solid waste into a high-calorific-value alternative to fossil fuels.2025-09-23
