In today’s fast-evolving solid waste recycling and resource recovery industry, traditional shredding equipment is reaching its limits in both throughput and particle size control. Whether preparing Alternative Fuels (AF/RDF) or processing recyclable plastics, operators are demanding higher stability, finer output control, and greater energy efficiency—requirements that conventional machines can no longer meet.

In 2025, China’s national energy-efficiency program spotlighted leading cement producers achieving record-low energy use. Huaxin Cement and Hongshi Group stood out as industry front-runners, showing how large-scale integration of Refuse-Derived Fuel (RDF) can redefine low-carbon production.

In the solid waste resource recovery chain, efficient sorting remains the linchpin for downstream processing success. Yet, when confronting municipal solid waste (MSW) with moisture content exceeding 50%, sticky and compacted food waste, or complex aged landfill refuse, conventional trommel screens and other equipment often falter.

In the fast-evolving world of solid waste management and plastic recycling, outdated shredders are holding back progress.

Harden Machinery Ltd. has successfully completed a stringent review by the Guangdong Provincial Department of Industry and Information Technology, earning renewal of its 2025 National "Specialized, Sophisticated, Special, and Innovative SMEs" (Little Giant) designation.

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.

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).

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.

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 coal
