Direct feeding without adequate pre-treatment can create serious operational problems.

How Can Lightweight Plastics from Municipal Solid Waste Be Converted into Oil Through Shredding and Pyrolysis?

Front-end pre-treatment efficiency directly determines downstream chemical recycling performance in post-consumer plastic reprocessing. Inadequate particle size control, material wrapping, and residual inorganic contaminants lead to incomplete thermal pyrolysis, reactor coking, catalyst poisoning, and reduced processing yields.

Traditional Refuse-Derived Fuel (RDF) and Alternative Fuel (AFR) preparation systems rely on multi-stage shredding circuits, causing high energy consumption, large footprint requirements, and intensive maintenance.

Low-value post-consumer flexible plastics—including garbage bags, courier packaging, and thin films—represent approximately 46% of global plastic production.

Paper manufacturing generates high-volume, highly entangled solid waste streams—including pulper ropes, paper sludge, rejects, and fiber residues.

Rising global energy costs are accelerating chemical recycling and pyrolysis oil production from low-value municipal waste plastics (such as post-consumer films, single-use bags, and flexible packaging).

Converting low-value post-consumer plastics—such as contaminated packaging films, flexible bags, and multi-layer composites—into pyrolysis oil requires specialized upstream pre-treatment.

Primary shredding serves as the critical initial pre-treatment stage in Municipal Solid Waste (MSW) recovery lines.
