What is PET plastic recycling washing line？
A PET plastic recycling washing line is an industrial system that washes and processes post-consumer or post-industrial PET (polyethylene terephthalate) plastic waste, converting it into clean flakes that can be reused in the production process. PET is commonly used to make bottles, food containers and packaging, so recycling is essential for sustainable development.
Key components of a PET recycling washing line
1. Conveying and sorting system
– Conveys waste PET bottles to the line.
– Manual or automatic sorting (e.g., removal of non-PET materials such as caps, labels, PVC, etc.).
2. Pre-washing (crushing and rough washing)
– Plastic crushers or plastic shredders break bottles into small flakes.
– Hot pre-wash tanks remove loose dirt, labels and adhesives.
3. Label and cap removal
– Float-sink separation removes the caps (usually PP/PE, which float on the water) from the PET bottle flakes (which sink).
– Friction washers or label removers tear off the remaining labels.
4. Deep Cleaning and Washing
– High friction washers scrub the flakes to remove stubborn contaminants.
– Chemical washing (optional) uses caustic soda (NaOH) to dissolve glue and residues.
– Hot water rinse ensures thorough cleaning.
5. Dehydration and Drying
– Centrifugal dryers remove most of the water.
– Hot air dryers (or thermal dryers) evaporate the remaining water.
6. Metal and Final Contaminant Removal
– Metal detectors or eddy current separators remove metallic impurities.
– Air separation or optical sorting removes remaining non-PET particles.
7. Storage and Packaging
– Cleaned PET flakes are stored in silos or packaged and sold to manufacturers of plastic products.
Final Products:
– Cleaned PET flakes (for new bottles, polyester fibers, sheets, etc.).
– By-products (HDPE/PP recycled from bottle caps, residual waste for energy recovery).
PET washing line installation considerations:
– Capacity: small (1-2 tons/day) to large (10 tons/day and above) systems.
– Automation level: manual sorting vs. fully automatic sorting.
– Water recycling: closed-loop system can reduce water consumption.
