Rotajet Separation Systems for Upgrading Existing Plants
The UK plastic recycling industry is evolving rapidly.
Rising contamination levels, mixed polymer streams, and tighter end-user specifications mean that plastic recycling machinery in the UK must now deliver higher levels of separation, consistency, and efficiency than ever before.
Across the UK, many recycling plants already operate with:
- Shredders and granulators
- Basic plastic washing lines UK
- Drying equipment
Yet they still struggle with:
- Inconsistent recyclate quality
- High contamination carryover
- Inefficient water usage
- Reduced material value
In many cases, the limiting factor is plastic separation machinery UK.
This is why more operators are now choosing to retrofit advanced plastic recycling machinery into existing plants, rather than replacing complete systems.
Why Separation Defines Plastic Recycling Machinery UK Performance
In modern recycling operations, throughput alone is not enough.
Material quality defines profitability.
Without effective plastic separation machinery UK:
- Mixed polymers reduce recyclate value
- Contamination affects downstream processing
- Output becomes inconsistent
- Processing costs increase
Modern systems are now built around:
- High-intensity plastic washing systems
- Advanced sink float tanks
- Integrated water filtration and recirculation
These operate as a multi-stage process, improving quality at each stage.
Rotajet Plastic Recycling Machinery UK – Built for Retrofit Integration
Rotajet Systems Ltd, based in Wakefield, manufactures plastic washing lines UK and plastic separation machinery UK designed specifically for retrofit applications.
Their systems are modular and integrate into existing plants with minimal disruption.
Key technologies include:
- High-intensity plastic washing systems
- Advanced sink float tanks
- Integrated size reduction equipment
- Industry-specific plastic recycling applications
Rotajet focuses on complete process performance, not just individual machines.
Typical Plastic Washing Line Process in the UK
A modern plastic washing line UK follows a structured process:
- Size reduction (shredding/granulation)
- High-intensity washing using a plastic washing system
- Density separation using sink float tanks
- Water filtration and recirculation
- Dewatering and drying
This staged process ensures consistent, high-quality output.

| Separation Upgrade | Sink float tanks | Density separation | Higher purity | Mid-line |
| Filtration Upgrade | Water filtration systems | Removes fines | Stable process | Water system |
| Full Upgrade | Combined system | Multi-stage cleaning | Maximum output quality | Full line |
| Retrofit Integration | Rotajet modules | Upgrade plant | Lower CAPEX | Existing layout |
Traditional vs Retrofit Plastic Recycling Machinery UK
| Factor | Traditional Systems | Rotajet Retrofit Systems |
| Cost | High | Lower |
| Downtime | High | Low |
| Flexibility | Fixed | Modular |
| Performance | Limited | Improved |
| Water Usage | Higher | Reduced |
| ROI | Slower | Faster |
Retrofitting is now widely seen as the most practical upgrade route.
Sink Float Tanks UK: Core Plastic Separation Machinery
Sink float tanks are a key technology in modern recycling.
- PP and PE float
- PET, PVC, metals sink
This allows:
- Polymer separation
- Contaminant removal
- Improved recyclate quality
Plastic Washing Systems UK: High-Intensity Cleaning
Effective separation depends on proper cleaning.
High-intensity plastic washing systems remove:
- Dirt
- Oils
- Labels
- Residues
This improves downstream plastic separation machinery UK performance.
Water Filtration and Recirculation
Water quality is critical.
Rotajet systems integrate:
- Filtration
- Screening
- Recirculation
Supporting systems like screening equipment help maintain stability.
