Thatchers Cider has introduced new, lighter weight cans for its cider, saving the equivalent of 5.9 million empty cans a year.
The Somersert cidermaker figures the change will save around 70 tons of aluminium and 381 tons of CO2 a year.
The move is latest element of Thatchers's sustainability drive. Thatchers was the first cider maker to ditch plastic ring carriers from its four-packs of cans, replacing them with recyclable board outers.
Martin Thatcher, fourth-generation boss of the firm, said: "As well as running a business, we are all, as individuals, passionate about cutting waste and doing our bit to bring about change.
"Investing in sustainability is one of our key priorities. However, it's equally important to retain quality, ensuring that the durability of the new lighter cans is not affected. So the Ardagh Group worked hard to get the weight exactly right."
He added: "We're continuing to invest in sustainability throughout all stages of the cidermaking process, from development of our new energy efficient warehouse and mill at Myrtle Farm, through to ambitious plans to reduce to zero, waste sent to landfill from the cidermaking process."
