In the evolving landscape of sustainable manufacturing, leading cement producers are accelerating the shift from coal to refuse-derived fuel (RDF) as a viable alternative. This transition isn't just a regulatory checkbox—it's a strategic imperative driven by cost stability, emissions reduction, and circular economy principles. As of 2024, industry benchmarks underscore this momentum, positioning RDF as a cornerstone of thermal substitution in cement kilns.

Harden Machinery Ltd. proudly unveils its renewed product brochure, reflecting our continued commitment to high-performance solid waste resource recovery. This updated edition highlights more than 15 years of technological innovation in shredding, screening, and separation, the core competencies that define Harden’s position in the industry.

As global industries accelerate their shift toward low-carbon operations, Alternative Fuels and Raw Materials (AFR) have become a vital pathway for cement co-processing, energy substitution, and waste-to-resource applications.

In the push toward carbon neutrality and zero-waste cities, large-scale waste plastic recycling has become essential. Many recyclers invest heavily in advanced pyrolysis or depolymerization technologies, yet overlook the critical first step: effective shredding pre-treatment. Inconsistent particle sizes, stubborn impurities, and limited throughput in this stage can severely restrict downstream chemical recycling efficiency and prevent true scalability.

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.
