When extrapolated to the consumption of cold cuts in Germany, this represents a reduction of 4,090 tons of CO2 equivalent per annum, corresponding to around 30,000 driven car kilometres,” says Nils Thonemann from the Department of Sustainability and Resource Management at the Fraunhofer Institute UMSICHT. “In the case of sausage spread packaging, using the clip closure solution saves up to 0.04 kg CO2 equivalent per comparison unit, or 3,270 tons of CO2 equivalent in terms of the total annual German consumption of sausage spread.”
