Beverage giant Diageo has revealed that it is investing £16m in an initiative which will see all plastic packaging removed from its Guinness, Smithwicks and Harp multipacks. Plastic shrink wraps currently used to house products, and the flexible plastic six-pack rings used to keep the cans together, will soon be replaced by cardboard sleeves and boxes. This is claimed to reduce Diageo’s plastic waste footprint by 400 tonnes per year. This is the weighted equivalent to the amount of plastics used to make 40 million 500ml drinks bottles.
