In trials funded by the Waste and Resources Action Programme (WRAP), Coca-Cola Enterprises will use recycled PET plastic (rPET) in a range of drinks bottles.
A Coca-Cola spokesman said: ""We are pleased to be working with WRAP, using our experience of processing recycled PET elsewhere in the world to explore the potential market in the UK."
Meanwhile, working together with London Remade and sustainable packaging manufacturer Closed Loop London, Marks & Spencer will use rPET in a selection of their food and beverage packaging lines, including juice and smoothie drinks bottles and prepared salad bowls.
The trial packaging will be clearly labelled as containing recycled plastic and consumer attitudes will be tested through market research.
Beyond food and drink, Boots will trial rPET in bottles containing personal care products.
