Coloured caps on milk bottles are set to be scrapped in a new partnership between Waitrose and Muller as part of a plastic recycling trial. The supermarket chain will sell Muller products with clear caps on their bottles, which can be recycled into food-grade packaging, unlike the usual blue, green and red lids.
The businesses estimate that this could increase the availability of recyclable plastic, high-density polyethylene (rHDPE) on the market by 1,560 tonnes a year. The trial will take place at all 331 Waitrose stores between April 4 and 30, following a successful in-house trial, they added.
Research, conducted by Muller, found that the majority of shoppers support the change, with 80 per cent telling the brand they would choose a bottle with a recyclable clear cap over a coloured cap.
