Sweden to boost its recycling efforts with higher deposits on aluminium cans & pet bottles
The deposit for PET and aluminium beverage containers is expected to rise, encouraging consumers to sort materials correctly to benefit the climate and the environment. Returpack, the Swedish DRS company, will raise the deposits on all packaging: from SEK 1 to SEK 2 for aluminium cans and small PET bottles and from SEK 2 to SEK 3 for large PET bottles. About Sweden’s DRS The goal for Sweden's DRS is to maintain a stable rate above 90 per cent, yielding significant environmental benefits. In 2023, 2.7 billion packages were deposited and returned to the recycling loop, achieving a deposit rate of 88.5 per cent. “The refund is that little added value that makes the deposit return scheme work so well. Now we are turning it up a notch by increasing the deposit amount on all packaging, making...
