It uses up to 90% less packaging waste than glass bottles, according to Christopher Lake, director of UK sales, and its carbon footprint is up to 80% less than that of glass bottles.
Asda will be stocking the green packs from this month.
"We’re all aware how important it is to do our bit to help the environment. In our industry, reducing packaging has to be one of our main aims,” Lake said.
