Polypropylene (PP) is one of the most widely used plastics in the world—valued for its strength, chemical resistance, and versatility. Commonly found in packaging, automotive parts, textiles, and consumer goods, it plays a central role in global supply chains. Yet despite its popularity, an estimated 99% of polypropylene still ends up in landfill.
This low recycling rate isn’t due to a lack of value. In fact, recycled PP (rPP) is in high demand—especially from manufacturers looking to reduce costs and environmental impact. The issue has historically been the cost and complexity of recycling. But with modern advances in technology, along with increasing legislative and commercial pressure, polypropylene recycling is not just viable—it’s profitable.
At Rotajet, we’ve developed turnkey recycling systems specifically for polypropylene, helping recyclers extract high-quality material for resale while dramatically reducing landfill waste.
Rotajet’s modular recycling systems take polypropylene waste through five essential stages to transform contaminated PP into clean, dry, uniform granulate ready for extrusion or resale.
Ensure consistent polypropylene feed and maximize plant throughput with Rotajet’s feed hopper, featuring an inverter-driven multi-screw system that prevents blockages and minimizes downtime.
After shredding, the material passes through a friction washer, which uses high-speed rotary paddles and water jets to remove contaminants like dirt, adhesives, and other impurities. This crucial step helps ensure that the final product is clean and ready for further processing.
Using sink float technology, Rotajet separates plastic film from heavier contaminants such as sand, dust, and other impurities. This step is essential for preventing abrasive materials from damaging the machinery in subsequent stages.
To eliminate excess moisture, the granulated material is subjected to a horizontal mechanical dryer. The high-speed rotor helps efficiently remove moisture, preparing the material for extrusion into finished products.
The final step in the process uses a screw press to expel any remaining moisture from the plastic. This ensures that the film is completely dry and ready for extrusion, ensuring high-quality recycled pellets that can be used in manufacturing new products.
With landfill bans tightening and demand for recycled plastics growing rapidly, now is the time to invest in a polypropylene recycling system that works.
