Plastic PET Bottles Washing and Pelletizing line
PET Bottle Washing & Pelletizing Line: From Waste to Food-Grade Raw Material
Plastic is a valuable resource. Through closed-loop regeneration, discarded PET can become a sustainable energy and material source. Our PET Washing and Pelletizing Line is designed to bridge the gap between waste and high-quality production.
We prioritize a low-energy process that maintains the highest quality standards. This allows you to transform post-consumer bottles into rPET (recycled PET) that is clean enough for food-grade packaging.
Why This Recycling Line is Different
Most recycling systems focus only on cleaning. Our solution focuses on Value Recovery.
Low Energy, High Output: We use advanced heating and filtration to reduce power consumption while keeping production speeds high.
Food-Safety Standards: Our decontamination technology ensures the final granules are safe for direct food and beverage contact.
Stable Intrinsic Viscosity (IV): By using advanced SSP (Solid State Polycondensation) systems, we ensure your recycled pellets perform like virgin resin.
Total Contaminant Removal: Our washing stages effectively remove glues, labels, and caps to ensure 100% purity.
Diverse Solutions for the PET Lifecycle
This line is versatile enough to handle various streams of PET waste, converting them into premium raw materials for several industries:
1. Consumer & Food Packaging
Bottle-to-Bottle Recycling: Turn old beverage bottles into food-grade PET granules for new bottle production.
Household Containers: Process milk bottles, cosmetic jars, and household packaging into reusable flakes or pellets.
Food-Contact Compliance: Supply rPET pellets for stretch blow molding that meet strict safety requirements.
2. Industrial & Manufacturing Waste
Production Scrap: Recycle PET films, sheets, and injection molding waste directly from your factory floor.
High-Purity Granules: Deliver stable IV pellets for premium industrial parts that require consistent performance.
3. Textiles & Synthetic Fibers
Fiber Production: Create high-quality polyester fibers for the textile industry.
Non-Woven Materials: Supply the raw material needed for industrial fabrics and eco-friendly clothing lines.
4. Environmental & Waste Management
Municipal Collection: Efficiently treat post-consumer PET waste collected from urban recycling programs.
Circular Economy Support: Help brands reach their "Zero Waste" goals by providing a reliable, closed-loop recycling infrastructure.

Bottle and Sorting System Components
- Belt de-baler
- Belt trommel
- Manual sorting belt
- Belt pre-wash
- Screw loader
- Vibrating feeder

- Packing system
Viscosity Increase System – SSP
The SSP viscosity increase system combines vacuum technology, solid-state polycondensation (SSP), and a specially designed pelletizing extruder. This system ensures that the intrinsic viscosity (IV) of PET pellets meets required specifications and remains stable.
Even with variations in raw material moisture and IV levels, the system maintains consistent pellet quality. The stable IV output supports downstream processes such as stretch blow molding and enables up to 100% bottle-to-bottle recycling. Compared to bottle flakes, PET pellets provide uniform particle size, no powder formation, and more consistent viscosity.
Viscosity Increase System – LSP
The LSP system is suitable for PET film, sheets, scrap, fabric fibers, polyester cloth, waste silk, and similar materials. It uses a spray cooling vacuum exhaust device and a multi-screw large-area vacuum exhaust extruder.
The spray cooling vacuum exhaust device increases the PET melt surface area by up to 1000 times. The multi-screw extruder improves melt homogenization. Combined with a high-performance vacuum pump, the system removes glycol and increases polymerization. This process forms new PET molecules and raises intrinsic viscosity (IV).
Intelligent Data Terminal Consultant System
The system integrates digital tools for equipment maintenance and production monitoring. It supports automated maintenance notifications, fast work order creation, and real-time task execution updates through online messages.
This improves uptime, boosts production efficiency, and increases equipment utilization. The system also supports data analysis by providing indicators such as equipment failure rates and maintenance summaries, helping management make informed decisions.
