M&S pioneers UV tags on milk bottles to boost recycling transparency

UK – Marks & Spencer (M&S), a major British multinational retailer, has become the first UK retailer to implement invisible ultraviolet (UV) tags on its four-pint milk bottles, revolutionizing the tracking of plastic packaging through the recycling process. 

The step, developed in partnership with recycling technology firm Polytag, aims to provide real-time data on the journey of packaging from shelf to sorting facility, enhancing transparency and accountability in waste management.

According to the initiative’s framework, the UV tags are embedded in the labels of M&S’s milk bottles, enabling them to be scanned by specialized detection units at recycling facilities. 

The system offers detailed insights into the recycling process, allowing M&S to monitor the lifecycle of its packaging with unprecedented precision. 

The data collected supports the retailer’s sustainability goals, ensuring accurate recycling claims and compliance with regulations mandating businesses to manage packaging waste responsibly.

“Retailers and brands can no longer afford to lose sight of packaging once it leaves their supply chain. With Extended Producer Responsibility (EPR) regulations now in effect, real data is essential,”  Polytag’s chief executive, Alice Rackley said.

“By tagging products and tracking their recycling journey, we’re creating a clear line of sight from shelf to sorting facility. M&S’s pioneering step signals a commitment to transparency and a transformative shift in industry responsibility.”

The initiative is also expected to reduce costs associated with EPR regulations by improving reporting accuracy, a critical factor as businesses face increased financial responsibilities for waste management.

M&S has further demonstrated its commitment by investing US$134,396 in Polytag’s Ecotrace programme, which seeks to establish a nationwide network of UV tag readers to enhance recycling infrastructure across the UK.

A recent update highlights that other major retailers, including Co-op, Waitrose, and Aldi, are also collaborating with Polytag to integrate UV tags into their product lines, indicating a growing industry trend toward advanced recycling solutions. 

Mark Hitschmann, head of packaging at M&S Food, expressed enthusiasm for the project, saying, “Reducing plastic is central to our Plan A journey to net zero.”

“This initiative provides valuable data on our packaging’s real-world impact, empowering our customers to trust that M&S is making sustainable choices easier.”
