WRAP research finds lightweight PET bottles are greener

PET lightweighting case studies just published by the Waste & Resources Action Programme (WRAP) have found that PET bottles can be more environmentally efficient by using less materials and weighing less. The topic was also discussed at an earlier WRAP seminar in June, which included presentations from industry experts involved in producing PET bottles, caps and performs. The two case studies, with Coca-Cola Enterprises and Esterform Packaging, explain how lightweighting PET bottles can save packaging without compromising product quality or consumer appeal. Coca-Cola lightweighted its 500ml bottle in the UK moving from 26g to 24g while maintaining its iconic shape. While Esterform lightweighted a 500ml carbonated drinks bottle by 20% and a two litre bottle by 5%. WRAP retail team member Peter Skelton said: WRAP wants to work with the packaging and drinks industries to identify areas for collaboration and the challenges that need to be addressed to deliver further progress.
