Müller Milk & Ingredients has switched all of its coloured milk bottle caps to clear in attempts to reduce dependency on virgin plastic by more than 1,500 tonnes per year.
The dairy company began switching its coloured caps out since winter last year across its dairies in Britian.
The process is now complete. All private label and branded milk produced by Muller Milk & Ingredients carries a clear cap.
Müller’s bottles are already manufactured on site to eliminate the need for road transport of empty bottles, and are also fully recyclable and are made of at least 30% of recycled materials (rHDPE). However, its coloured caps cannot be recycled back into food grade packaging.
By making this transition, Muller can retain the clear material to make new caps and bottles within the food sector.
With demand for rHDPE outstripping supply, a move to a closed loop system will increase its availability on the market by 1560 tonnes per annum. This will further reduce requirements for ‘virgin’ plastic.
Rob Hutchinson, chief executive at Muller Milk & Ingredients, said: “We wanted to do more to increase sustainable practices within the dairy industry.”
“Research carried out prior to our initial trial showed support from the majority of shoppers to change clear caps,” he added.
