Wrap's GlassRite Beer, Cider & Spirits project has helped over 60 lagers, ales and ciders convert to lighter glass bottles. Carlsberg UK worked with Ardagh to cut its 275ml bottle weight by 17%, saving 8,400/tpa glass and cutting more than 5,700/tpd CO2. Hall & Woodhouse worked with OI to develop a lighter bottle for its Badger ales, cutting weight by 27%, saving 1,500/tpa glass and cutting 1,100/tpa CO2. Cobra Beer communications manager Adam Barriball said: "In 2005, Wells & Young's one of our contract brewing partners in the UK, lightweighted our 330ml bottle. This produced glass savings of more than 200/tonnes. We then did the same to the 660ml bottle in 2007, reducing its weight by 21%, and so using 700/t less glass. We cut our CO2 by more than 450/t."
