Rotajet High-Performance Film & Rigid Recycling Systems
Rotajet Systems Ltd designs and manufactures industrial plastic washing systems in the UK for recycling operators worldwide. Rotajet plastic washing plants are engineered specifically for high-contamination post-consumer and commercial waste streams — not ideal laboratory conditions.
Plastic recycling profitability is no longer determined by bale price — it is determined by wash quality, contamination reduction and moisture control.
Contaminated plastics frequently contain:
- Organic residue
- Oils and fats
- Adhesives and labels
- Paper fibre
- Moisture levels exceeding 40–50%
Material quality standards promoted by WRAP and the British Plastics Federation continue to push recyclers toward higher-grade outputs and improved material consistency.
To compete, operators require industrial-grade plastic washing equipment built for real-world feedstock.
Why Many Plastic Washing Lines Underperform
Low-energy wash tanks alone cannot:
- Remove bonded oils and food residues
- Break down adhesive contamination
- Reduce moisture efficiently
- Prevent film wrapping and blockages
- Deliver extrusion-grade flake
Plastic streams can contain 50%+ moisture and significant organic contamination. Without aggressive friction washing and controlled dewatering, output quality remains downgraded.
Rotajet plastic washing systems are designed specifically to solve this.

A high-performance industrial plastic washing plant must operate as a fully integrated system.
Size Reduction & Opening
Precision shredding increases surface exposure and prepares film and rigid plastics for effective cleaning.

Typical throughput range:
500 kg/hr to 5 tonnes per hour
High-Intensity Friction Washing – RJ-Turbo
The core contamination removal stage.
The Rotajet RJ-Turbo friction washer operates at 800–1,200 RPM, generating intense mechanical shear by forcing plastics against a perforated basket and against each other.
This process:
- Strips oils and surface residue
- Breaks adhesive bonds
- Removes organic contamination
- Improves downstream separation
- Upgrades flake value

This is the stage that transforms contaminated waste into commercially viable recycled polymer.
Sink-Float Separation
Density-based separation isolates polymer fractions and removes heavier contaminants.

Mechanical & Thermal Drying
Rotajet centrifugal dryers reduce moisture to:
- 8–15% after mechanical stage
- <3% prior to extrusion (with final drying)

Lower moisture = lower energy cost and improved pellet quality.
Closed-Loop Water Systems
Rotajet plastic wash plants integrate filtration and recirculation to:
- Reduce fresh water demand
- Minimise effluent discharge
- Lower operating costs
- Improve sustainability metrics
Aligned with environmental compliance expectations from UK Government.
