10 Mar 2022 --- Müller is partnering with Waitrose on a trial to replace colored milk bottle caps with clear ones. Müller says the move could boost the availability of recycled HDPE (rHDPE) on the market by 1,560 metric tons annually. Unlike fully recyclable plastic milk bottles, colored milk caps cannot currently be recycled back into food-grade packaging. Introducing clear caps enables retention of the material for reuse within the food sector.With demand for rHDPE reportedly outstripping supply, keeping the material within a closed loop system can help drive up its availability and reduce dependency on virgin plastic.Müller’s fresh milk bottles are manufactured in-house, 100% recyclable and contain up to 40% food-grade recycled material, says the company.
