Description
Our standard PET bottle washing line provides a complete solution for transforming dirty bales of PET bottles into clean PET flakes ready for producing polyester staple fiber or further processing into plastic granules through pelletizing. ASG Machine offers standard washing capacities from 500kg/h up to 3000kg/h and can also manufacture custom wash lines with greater capacities to meet specific operational requirements.
Our PET recycling line operates fully automatically, with each piece of recycling machinery connected via belt or screw conveyors. The entire washing line is controlled through a central electric control panel and cabinet, ensuring seamless operation and monitoring.

Debaler Machine – PET bottles (with caps & labels) typically arrive in compacted bales tied with metal wires. The debaler breaks apart these bales, allowing the plastic bottles to drop onto a belt conveyor that transports them to the next processing stage. This initial step creates a “free flowing” stream essential for efficient recycling. Learn more about our debaler machine.
Trommel Separator – This large, slow-rotating machine removes small contaminants. The trommel’s core features a mesh screen tunnel rotating at 6-10 RPM. The screen holes are sized to retain PET bottles while allowing smaller contaminant particles to pass through. This pre-cleaning stage significantly improves the quality of material entering subsequent processes. Learn more about our trommel separator.
*
Wet Granulator / Crusher – The bottles are cut into “flakes” through our wet granulator. The granulator utilizes an open rotor equipped with heavy-duty knives spinning at high speeds. As PET bottles enter the cutting chamber, these rotating knives contact stationary knives, reducing the bottles to small pieces. A screen with 12-18mm diameter holes controls flake size; PET material continues cutting until sufficiently small to fall through. Water sprayed into the chamber simultaneously washes the material and acts as a lubricant to reduce knife friction. Learn more about our wet granulator.
Label Separator – The material stream exiting the granulator contains PET flakes mixed with paper and PP/PE/PVC film from labels, plus PP/PE rigid plastics from bottle caps. The label separator uses a column of pressurized air to blow away lighter paper and plastic film into a separate collection tank, initiating the separation process. Learn more about our label separator.
Sink / Float Separation Tank – This large water tank separates materials by density, effectively removing remaining plastic films from labels and PP/PE bottle caps. Since labels and caps float while PET flakes sink, the valuable PET material can be easily extracted for further processing. Learn more about our sink float separation tank.
Hot Washer For PET Flakes – Functioning similarly to a washing machine, this unit processes PET flakes with boiling water to sterilize the material and remove stubborn contaminants such as label adhesives, grease, oils, and food residue. This thermal cleaning process is essential for producing high-quality recycled PET suitable for demanding applications. Learn more about our Hot Washer For PET Flakes.
Friction Washer – A secondary friction washer using cold water further cleans and cools the PET flakes through a scrubbing action. This additional washing stage ensures the final product meets stringent purity standards required by end-users. Learn more about our friction washer.
High Speed Dewatering Machine – This equipment uses centrifugal force to remove a significant portion of water from the PET flakes. As a cost-effective pre-drying solution, it substantially reduces the energy required in the subsequent thermal drying stage. Learn more about our dewatering machine.
Thermal Dryer + Cyclone Separator – The partially dried PET flakes undergo complete drying in thermal dryers where hot air mixes with the material, removing residual moisture. The final cyclone separator introduces cold air to cool the PET flakes for storage while also capturing fine dust particles as a final purification measure. Learn more about our thermal dryer.
Product Silo – A large storage tank holds the clean, dry PET flakes before they are packaged or transported for further processing or sale.
Pelletizer / Extruder – While most PET bottle recycling lines produce clean flakes directly for polyester staple fiber production, we offer pelletizing equipment as an optional addition. ASG Machine provides both single-screw and double-screw extruders for facilities requiring pelletized output. Learn more about our pelletizing equipment.

PET Flakes
We understand the importance of producing high-quality PET flakes that are not only clean but also low in contamination. To continuously evolve and improve our PET bottle washing lines, ASG Recycling has implemented a customer feedback system where samples of PET flakes from customers using our washing lines are collected and analyzed in our laboratory. Based on the numerous samples we received last year, we are confident our PET washing lines can achieve the following benchmarks:
- Moisture: < 1%
- Bulk density: < 0.3G/CM3
- Total impurity: < 100ppm
- PVC content: < 40ppm
- Metal content: < 10ppm
- PE/PP content: < 50ppm
- Particle size: < 14-16mm
Feel free to contact us if you have additional requirements.
Custom PET Bottle Recycling Lines
Depending on contaminants within the PET bottle bales, additional equipment may be required such as a separation table for manual sorting, metal detectors and removal systems, PVC heat separation, and more. ASG offers custom-tailored PET washing lines based on your specifications. Let us know your needs including capacity, type of PET bottles and packaging, and types of contaminants you expect, and our professional team of engineers will handle the rest.

Installation & Warranty
An installation package comes standard with our washing lines, where our engineers (one electrical and one mechanical) will travel to your facility and install the washing line for you. We also offer routine maintenance teams as well as operations consultants to ensure the PET recycling lines you purchase will run smoothly year after year.
All equipment from ASG Recycling comes with detailed operation instructions and an installation guide. A list of required replacement parts will also be provided at the time of purchase. All machinery and parts are warranted against manufacturer defects and come with a 1-year limited warranty.
