Introduction to PET Bottle Recycling Lines
In today’s environmentally conscious market, efficient and reliable PET bottle recycling is more critical than ever. ASG Recycling Machinery, in collaboration with industry leaders like ASG Machine, provides state-of-the-art, fully customizable PET bottle recycling lines designed to meet diverse industrial requirements. These systems transform used PET bottles—including water, carbonated drink, and oil containers—into high-purity, clean, and dry PET flakes ready for reuse in manufacturing polyester staple fiber, PET strapping, sheets, films, and even new bottles.
Customization is at the heart of our approach. By analyzing your specific input materials, expected contamination levels, desired output quality, and capacity needs, we engineer recycling solutions that maximize efficiency, reduce operational costs, and support sustainability goals.
How a PET Bottle Recycling Line Works
A typical PET bottle recycling line involves multiple stages, each critical to ensuring the output meets industry standards for purity and quality. The process generally includes:
- Bale Opening: Initial breaking of compressed bales of used PET bottles.
- Pre-sorting and Cleaning: Removal of large contaminants and labels through trommel screens and manual/automated sorting.
- Size Reduction: Grinding bottles into smaller flakes.
- Washing and Separation: Using float-sink tanks, hot washers, and friction washers to remove impurities, labels, adhesives, and other residues.
- Drying: Efficient dewatering and thermal drying to reduce moisture content.
- Final Screening and Storage: Ensuring flake uniformity and storing the finished product.
Each stage is optimized based on your facility’s requirements, with options for automation, water recycling, and energy-efficient designs.
Customization and Scalability
No two recycling operations are identical. That’s why ASG Recycling Machinery provides tailored solutions adaptable to a wide range of capacities—from 500KG/H to 3000KG/H, with options for even higher throughputs. Key customization factors include:
- Input Material Type: Water bottles, oil containers, colored PET, etc.
- Contamination Level: Lightly soiled vs. heavily contaminated inputs.
- Output Quality Requirements: Food-grade vs. industrial-grade flakes.
- Space and Layout Constraints: Compact designs for limited spaces.
- Automation Level: From semi-automatic to fully automated systems with central control.
Whether you are a small recycler or a large processing plant, our engineering team designs systems that align with your operational goals and budget.
Key Machinery in a PET Recycling Line
A robust PET bottle recycling line comprises several integral machines, each serving a specific function. Below is an overview of standard equipment, with capacities and configurations adjustable to your needs.
| Equipment | Function |
|———–|———-|
| Bale Opener | Breaks apart compressed bales for processing |
| Rotary Trommel | Pre-cleans and removes loose dirt and small contaminants |
| Sorting Belt with Metal Detector | Identifies and removes metals and non-PET materials |
| Wet Grinder | Reduces bottle size into flakes |
| Label Remover | Separates and eliminates bottle labels |
| Sink-Float Separation Tank | Divides materials by density; typically two stages |
| Hot Steam Washer | Uses steam to deep-clean and sanitize flakes |
| Friction Washer | Mechanically scrubs flakes to remove stubborn residues |
| De-watering / Centrifugal Dryer | Reduces surface moisture content |
| Hot Air (Thermal) Spiral Dryer | Dries flakes to ≤1% moisture |
| Product Silo | Stores finished flakes before packaging |
| Electric Control Cabinet with PID | Centralized automation and process control |
| Water Filtration/Recycling System | Recycles process water to reduce consumption |
Note: Screw and belt conveyors integrate these components into a seamless workflow.
Quality Output: PET Flake Specifications
Our PET recycling lines are engineered to produce flakes that meet rigorous quality standards, suitable for various high-value applications. Typical output specifications include:
- Moisture Content: < 1%
- Bulk Density: < 0.3G/CM³
- Total Impurities: < 100ppm
- PVC Content: < 40ppm
- Metal Content: < 10ppm
- PE/PP Content: < 50ppm
- Particle Size: 14–16mm
These metrics ensure that the recycled material is of high enough quality to be used in sensitive manufacturing processes, including food-contact applications where compliance is mandatory.
Industry Trends and Sustainability Benefits
The global push for circular economies has increased demand for efficient recycling infrastructure. Investing in a modern PET bottle recycling line offers:
- Regulatory Compliance: Meet increasing government mandates on recycling and sustainability.
- Economic Advantage: Turn waste into valuable raw material, reducing procurement costs.
- Environmental Impact: Significantly lower carbon footprint compared to virgin plastic production.
- Market Leadership: Position your brand as an eco-conscious industry player.
Technological advancements, such as AI-powered sorting and energy recovery systems, are making these lines more efficient and accessible than ever.
