Closed Loop Systems for Plastics: Rehoboth Granulation Lines Turn Waste into High-Value Reusable Pellets

1. Why Closed Loop Plastic Recycling Is No Longer Optional

Global brands and regulators are demanding nothing less than full circularity for plastics. The EU's Circular Economy Action Plan mandates 30% recycled content in plastic packaging by 2030, while major corporations like Coca-Cola and Unilever have committed to 25-50% recycled plastic in their products by 2025. Yet 90% of plastic waste still ends up in landfills or incinerators—not because it can't be recycled, but because most traditional granulation systems produce low-quality pellets that can only be used for low-value applications, breaking the closed loop.

The biggest barrier to true closed loop systems for plastics is inconsistent pellet quality. Traditional extruders struggle with contaminated waste, produce pellets with uneven melt flow, and degrade the plastic molecular structure during processing. This means recycled plastic can't replace virgin resin in high-value applications—until now. Rehoboth's waste plastic recycling and granulation systems are engineered to solve this exact problem, turning even heavily contaminated waste into pellets that match virgin resin quality.

2. Rehoboth Granulation Systems: Engineered for True Circularity

Unlike generic pelletizers that only handle clean, single-type plastic, Rehoboth's lines are built from the ground up for closed loop recycling. Our unique screw designs, advanced degassing systems, and precision filtration technology preserve the plastic's molecular integrity, producing pellets that can be directly reused in the same manufacturing processes they came from.

Three Specialized Lines for Every Plastic Waste Stream

We don't believe in one-size-fits-all solutions. Our three dedicated granulation lines cover every major plastic waste type, ensuring optimal performance for your specific feedstock: Film Plastic Recycling Line: Perfect for clean film, PP woven bags, agricultural mulch film, and BOPP printed products. Features top-tier compacting and degassing to prevent overheating and degradation, producing consistent pellets for new film production. Rigid Plastic Recycling Pelletizer: Designed for ABS, PE, PA, PP, PS, and ABS+PC grinding materials from injection molded parts, appliance shells, and automotive components. Delivers uniform pellet size and melt flow for injection molding applications. PET Plastic Recycling Pelletizer: The gold standard for bottle-to-bottle recycling. Enables direct pelletizing of washed PET flakes with precise intrinsic viscosity (IV) control, producing food-contact grade pellets that meet global safety standards.

Premium Core Components for 24/7 Reliable Operation

Every critical component of our granulation systems is built to last. Screws and barrels are made from nitrided steel and bimetal alloys for exceptional wear resistance, even when processing abrasive materials. Gearboxes, motors, and die heads are precision machined to handle continuous high-load operation, minimizing downtime and maintenance costs. All lines are also fully compatible with existing upstream washing lines and downstream packaging equipment, making integration into your existing production seamless.

3. How Our Closed Loop System Works: From Waste to Pellets in One Pass

Rehoboth's granulation lines deliver a fully automated, one-stop closed loop process that eliminates intermediate steps and reduces material loss: Belt Conveyor Feeding: Cleaned plastic flakes or scraps are automatically fed into the extruder Main Extrusion: Precision screw design melts and homogenizes the plastic without degrading its molecular structure Vacuum Degassing: Removes volatile organic compounds (VOCs), moisture, and residual odors High-Efficiency Filtration: Removes even the smallest contaminants to ensure 99.95% pellet purity Die Face Cutting: Produces uniform, consistent-sized pellets Vibration & Cooling: Cools and separates pellets before automatic packaging

This streamlined process ensures that every pound of plastic waste is converted into high-value reusable pellets, with minimal energy consumption and zero waste. Our advanced heat treatment process removes oil and adhesive residues in an oxygen-free environment, using only one-third the energy of traditional steam cleaning methods.
