From Bottle to Flake to Food-Grade Pellet — Complete PET Recycling Solutions
A PET Recycling Line is a synchronized series of machines that converts used PET (polyethylene terephthalate) bottles and packaging waste into clean recycled flakes or food-grade-quality recycled pellets, ready to re-enter manufacturing as new bottles, polyester fiber, packaging film, sheet, strapping, or injection-molded products. By combining de-baling, sorting, label removal, crushing, multi-stage cold-and-hot caustic washing, float-sink density separation, drying, vacuum decontamination, single-screw extrusion, filtration, IV-enhancing solid-state polycondensation, and underwater pelletizing into one seamless production flow, a modern PET line removes the glues, residues, PVC, paper labels, and PP/PE caps that would otherwise compromise pellet quality — delivering the purity required by demanding downstream applications including bottle-to-bottle food-grade manufacturing.
Torontech proudly offers a comprehensive PET recycling portfolio covering every level of investment, throughput, and pellet-quality requirement. The Plastic PET Bottles Washing and Pelletizing Line is the complete turnkey solution — integrating pre-treatment, caustic cleaning, multi-stage post-washing, drying, vacuum loading, 5-layer reactor processing, single-screw extrusion with melt pump and online viscosity measurement, and automatic underwater pelletizing — engineered for high-grade applications including fiber, film, and injection molding. The PET Bottle Washing Line is the dedicated flake-production platform with mechanical label remover, disk separator, caustic hot washer (1–2% NaOH at 70–90 °C, ~4.07 m³ chamber), high-speed friction washer, and centrifugal dewatering — delivering CE/CSA/TUV/SGS/ISO-compliant flakes ready for polyester fiber spinning. The PET Waste Recycled Plastic Pelletizing Machine adds SSP IV-enhancement technology for consistent food-grade-quality pellet output. And the LSP Series PET Plastic Recycling Machine Line with Polymerization System is the flagship — using cutting-edge Liquid State Polycondensation (LSP) technology to handle diverse feedstock from bottles to fabric fibers and produce a wide spectrum of high-value outputs.
Close the PET Loop with Torontech
Every recycled PET pellet that leaves a high-quality PET recycling line is a small but real victory for the circular economy — virgin plastic that didn't have to be produced, fossil-fuel feedstock that stayed in the ground, and post-consumer waste that didn't end up in a landfill, river, or ocean. But that promise is only delivered when the recycling line is engineered for the cleanliness, IV stability, and operational reliability that food-grade and fiber markets demand. The recyclers and beverage-industry leaders who consistently deliver world-class rPET are the ones equipped with PET recycling lines built for capacity, automation, food-grade decontamination, and rigorous quality control — and the Torontech PET recycling portfolio gives you exactly that.
Whether you are launching a new bottle-to-bottle facility, expanding a polyester-fiber recycling operation, processing diverse PET waste streams with LSP polymerization technology, or commissioning a complete turnkey PET washing and pelletizing line, Torontech has the platform engineered to meet your exact needs. Equip your facility with the PET recycling solutions trusted by recyclers, beverage companies, and circular-economy operators worldwide.
Applications in Industries
- Bottle-to-Bottle Food-Grade Recycling — Production of food-grade rPET pellets for new beverage bottles via SSP IV-enhancement, enabling up to 100% bottle-to-bottle technology under EFSA/FDA-style recycling protocols.
- Polyester Fiber & Textile Industry — Clean PET flakes spun into polyester staple fiber for fleece, carpet, automotive textiles, non-wovens, and apparel — the largest single market for recycled PET globally.
- Sheet & Film Extrusion — Stable rPET pellets for thermoformed trays, blister packaging, A-PET / G-PET sheets, and food-contact film production.
- Packaging Strapping — Production of durable PET strapping bands for logistics, palletization, and industrial bundling applications.
- Injection Molding & Compounding — PET pellets for molded parts — caps, containers, housings, engineering components — and PET compounds for advanced material applications.
- Municipal & Industrial Waste Management — Large-scale PET reclamation facilities, deposit-return systems, MRF operators, and beverage-industry circular-economy programs.
- Diverse Feedstock Recovery — LSP polymerization technology recovers value from PET film, sheet, perforated waste, fabric fibers, polyester cloth, and waste silk — well beyond traditional bottle streams.
