HDPE Bottle Washing Recycling Line
An automated HDPE bottle washing recycling line engineered for post-consumer resin (PCR) feedstocks, including detergent, milk, shampoo, and household-chemical bottles. Crushing, friction washing, density separation, and thermal drying are synchronised to turn contaminated plastics into clean rHDPE flakes—ready for extrusion, compounding, or direct feed into our Plastic Pelletizers.
Modular infeed, high-torque wet crushing, optional hot washing, and closed-loop water treatment empower you to achieve premium flake purity even with heavy labels, caps, sand, and chemical residues in the stream.

Why Our HDPE Bottle Recycling System Excels
- Stable Output, Lower Operating Cost
Continuous conveying and PLC recipes stabilise throughput while optimising power and water consumption.
- Deep Cleaning for Bottle Residues
Wet crushing, friction scrubbing, and optional hot washing remove oils, detergents, and odours to deliver cleaner rHDPE flakes.
- Label & Light Contaminant Removal
Air separation and screening reduce labels, films, paper, and dust—improving purity and downstream processing stability.
- Closed-Loop Water Treatment Ready
Designed to integrate filtration and recirculation systems to reduce discharge and simplify compliance.
Standard HDPE Bottle Washing Process Flow
From baled post-consumer bottles to purified rHDPE flakes—each stage is configured to your contamination level and target flake purity.
- Debaling & Pre-sorting
Open bales, remove metals/oversized impurities, and stabilise continuous infeed.
- Wet Crushing
Reduce bottles to uniform flakes while flushing loose residues, sand, and dirt in a high-water-volume chamber.
- Friction Washing
High-speed mechanical scrubbing (over 1000 RPM) aggressively detaches labels, glued paper fibres, and stubborn dirt.
- Hot Washing (Optional)
Chemical thermal washing softens glues and extracts oils, dairy fats, and stubborn detergents, ensuring food-grade or premium rHDPE.
- Sink-Float Separation
Density separation floats the targeted HDPE/PP while sinking heavier foreign plastics like PET, PVC, and metals.
- Dewatering & Thermal Drying
Automated centrifugal dewatering coupled with hot air drying reduces surface moisture to below 1%, preparing flakes for silos.
Inside the Line: Core Recycling Equipment Composition
A professional HDPE bottle washing recycling line is constructed from heavy-duty modules—each engineered for maximum decontamination, rigorous density separation, and energy-efficient drying.
| Equipment Component | Primary Function |
|---|---|
| Bale Opener / Feeding Conveyor | Opens bales (optional) and ensures stable, continuous feeding into the line. |
| Pre-washer / Trommel (Optional) | Removes sand, stones, and loose dirt early to protect downstream machines and reduce water load. |
| Wet Crusher / Granulator | Size-reduces bottles while flushing away loose contamination for efficient downstream washing. |
| Friction Washer | High-speed scrubbing removes stubborn residues, paper fibres, and remaining dirt from flakes. |
| Hot Washer (Optional) | Improves decontamination for oily or detergent-heavy bottles using heated water and controlled chemistry. |
| Sink-Float Separation Tank | Density separation where HDPE/PP typically float while PET/PVC and heavy contaminants sink. |
| Rinse & Transfer Screw | Rinses flakes and transfers material between stages while maintaining consistent residence time. |
| Centrifugal Dewatering | Mechanically removes surface water to reduce thermal drying energy demand. |
| Thermal Dryer & Air Transport | Hot-air drying brings flakes to low moisture content and conveys them to storage. |
| Zig-Zag / Air Classifier | Removes labels, films, and light fractions to improve final purity. |
| Silo / Bagging Station | Stores and packs the finished HDPE flakes for easy logistics and stable feeding to pelletising lines. |
| PLC Control System | Centralised HMI/PLC control for interlocks, recipes, alarms, and optional remote diagnostics. |

FAQs on HDPE Bottle Washing Recycling
It is designed for post-consumer HDPE bottles (milk, detergent, shampoo, household chemicals), typically with labels and closures attached. Feedstock can be baled or loose, and we can tailor infeed and washing stages based on contamination level and target purity.
Multi-stage friction washing, optional hot washing, and density separation reduce labels, oils, and residues. Final cleanliness depends on incoming material, but the line is configured to deliver low contamination and low moisture flakes for pelletising or compounding.
Yes. Air classification targets labels and light fractions, while sink-float separation helps remove heavier plastics (typically PET/PVC) from HDPE/PP. For higher-purity requirements, optional sorting and metal detection can be integrated upstream.
Central PLC with touchscreen HMI provides recipe control, safety interlocks, and real-time monitoring of water, energy, and throughput. Remote diagnostics and data logging can be included for predictive maintenance.
