New PET Recovery Plant launched in Washington last year

The UK’s leading sustainable waste management company, Biffa, has placed 1,600 tonnes of previously wasted plastic back into the circular economy since commissioning its PET Recovery Plant in Washington last year.

The Group has pioneered new technology that targets, then captures, tiny flakes of recyclable material from contaminated waste. 

The plant has now been recognised by the recycling industry’s flagship Awards for Excellence as the ‘Best Use of Design and Technology in a Waste Management Facility’.

The recycling process starts at Biffa’s neighbouring Seaham plant in County Durham, where PET contaminated by aluminium or PVC is removed to ensure only the highest quality material goes on to be recycled into food-grade products. During this sorting and flaking process, some of the good quality plastic is invariably caught up with the contaminated material, meaning that historically it could not be recycled. 

The contaminated material is now taken to the Group’s new PET Recovery Plant in Washington, where Biffa’s state of the art technology enables magnetic currents to remove the residual metal, while optical sorters remove any remaining traces of PVC, leaving only the recyclable PET flakes behind. This material is then able to re-enter the recycled polymer supply chain, delivering significant financial and sustainability benefits. 

Phil Goodier, Biffa Polymers Managing Director, said: “This award is testament to Biffa’s vision, and commitment to delivering innovative solutions to help tackle the UK’s waste challenge. Through this latest technology we are able to apply new recycling processes which can ultimately capture valuable high-quality PET that would otherwise be lost in the waste stream. With more than £50million invested in plastics recycling infrastructure since 2016, Biffa recycles over 150,000 tonnes of plastic every year, with plans in place to drive further growth in the coming years”.

The PET Recovery Plant was built inside Biffa’s existing plastic recycling facility in Washington which, alongside the company’s other polymer plants in Seaham and Redcar, cements it as the UK’s leader in recycled food-grade PET and HDPE.
