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In the fast-evolving world of solid waste management and plastic recycling, outdated shredders are holding back progress.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

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).
