The company was started in 1960 by Derek Parnaby who developed the world famous ‘Parnaby Process’ of minerals separation using barrels and cyclones.

In 1974 we started to manufacture the dense medium washing plant which maximises value from coal beneficiation.

During the 1970s and 1980s we developed a comprehensive range of effluent treatment systems.

In the 1990s we began to manufacture mobile units and provide contract services and in the last 10 years, we have been pioneering cost-effective systems for plastic recycling as an alternative to landfills.

We manufacture almost all the equipment we supply in our purpose-built 20,000 square metre site in North East England.

The Parnaby Cyclone washing plant was first used for polymer separation in the Automative and WEEE sectors and has now extended to include ridged polymers. This has led to Parnaby’s now increasing their range of washing and separation equipment to suit the different requirements across these industries.

Plastics that can be separated via the Parnaby plastic separation technology include:

• PP (Poly-propylene)
• PE ((Polyethylene)
• PS (Polystyrene)
• ABS (Acrylonitrile Butadiene Styrene)
• Other Plastics
