Odour Control: Identifying odour and deodourising recycled polymers

Of the UK’s 260,000 tonnes of post-consumer polypropylene waste, under 1% is recycled into high quality products (e.g. automotive applications). One of the main reasons for this is the fact that polymers retain odours from their previous applications (e.g. containers for food, sauces, detergents), which deems them unviable for use in the production of high value products. 

The Odour Control project aims to create a validated prototype of a process to provide a cost-effective method for identifying odour and deodourising recycled polymers, which can then be implemented during the manufacture of higher value products. 

Project Outcomes 
• We’re delighted to say that we have installed a state-of-the-art, modified laboratory-scale extrusion line with vast flexibility of machine configuration for development of the process 

• The project consortium has also designed and built bespoke processing technology, which is undergoing operational testing 

• Laboratory trials for experimentation on the deodourising prototypes and their effectiveness are being carried out in the coming months and into next year 

We are currently in talks to develop this important piece of work further. Odour control is one of the key challenges in the arena of utilising recycled plastics, so we are committed to playing our part in finding a viable, long term solution.  

Our sincere thanks to our funding body, Innovate UK and to our project partners, the University of LincolnMatrix Moulding Systems and IPL Global.
