Chemical recycling of waste plastics—such as pyrolysis and hydrogenation—often faces operational bottlenecks like reactor coking, catalyst poisoning, and fluctuating yields. These issues stem from improper feed quality rather than reactor design.

Physical and chemical plastic recycling present fundamentally different pre-treatment requirements.

High moisture content and wrapping-prone materials (such as textiles and plastics) cause frequent clogging and unplanned downtime in solid waste processing.

Paper recycling and manufacturing generate complex solid waste streams, including ragger tails, light rejects, pulper waste, and plastic-fiber mixtures.

Traditional cement kilns struggle to scale Alternative Fuel (AFR) adoption due to raw waste heterogeneity, high ash content, and uneven calorific values.

Integrating advanced solid waste pre-processing systems into cement plants converts complex industrial and municipal waste into high-grade Refuse-Derived Fuel (RDF/SRF). This process enables ultra-high Thermal Substitution Rates (TSR), slashes fossil coal consumption, and drastically cuts CO₂ emissions while maintaining operational stability.

Hard Target by End of 2025: 30% of cement kiln production lines must integrate Alternative Fuel (AF) technologies, with target thermal substitution reaching 10%.

When improperly handled, waste tires pose severe environmental threats: landfilling consumes vast land and resists degradation, open stockpiling breeds insects and creates severe fire hazards, and primitive incineration releases hazardous toxic gases. For years, waste tire disposal has remained a critical environmental challenge.

From July 29 to 30, 2026, the 15th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference is being held in Wuhu, Anhui. Focusing on carbon reduction, cost efficiency, and digital intelligence, the event explores practical pathways for the cement industry to navigate the dual-carbon era.
