The UV detection technology, provided by Polytag, is integrated into the site’s existing commercial sorting line and will pair with Pellenc ST’s near-infrared sorting capabilities.
The system promises to provide real-time, accurate data for better visibility of material flows.
Stuart Hayward-Higham, Chief Technical Development and Innovation Officer at SUEZ in the UK, said: “We are proud to be the first recycling centre to host this innovative module on our sorting line.
“The technology will give us richer insight into the composition of the packaging we process, helping us in the long term to optimise operations and deliver higher quality recyclates to our customers.”
Suez said that the development marks a “major milestone” in the move towards the large-scale adoption of digital watermark technology and suggested it would be deploying the technology across its European recycling facilities.
Polytag UV readers
Polytag was founded in 2018 with the aim of improving material data and waste traceability.
The technology company produces consumer-facining UV codes, invisible watermarks and detection equipment which is installed directly onto sorting belts.
Pellenc ST
Pellenc ST produces optical sorting machines for use across the waste and recycling industry.
Its technology was recently deployed as part of a €42 million (£32.3 million) PreZero solid recovered fuel (SRF) production facility in Spain.
The site is thought to be Spain’s largest SRF facility with a capacity of 200,000 tonnes annually.
Pellenc technology is also set to be installed at a McKinstry £16 million construction, demolition and industrial (CD&I) waste recycling facility in Northern Ireland.
