An additional filling line was integrated in the data capture pro- gram in 2014 so that more than 45 percent of compressed air consumption is now measured. Some of the consumption resulted from the utilization of filling facilities for stand-up pouches. Suitable for combustible products, the facilities were equipped with explosion-preventing pneumatic controls. Increased consumption in 2013 is attributed mainly to operation of additional filling lines for stand-up pouches and a third filling line for household cleaners. The reduction in 2014 can be traced to optimized utilization of machine ca- pacity. As the result of an increase in filling amount (+ 3.2 percent) in 2015 and the reduction of batch sizes, consumption rose by 1.7 percent per kilo- gram. In relation to the number of produced pieces (+ 9 percent), however, specific consumption was reduced by 3.7 percent after optimization measu- res were implemented in the filling lines. “Sustainability requires networks. Our initia­ tives achieve greater relevance with the tar­ geted involvement of political and business decision makers. ” Timothy Glaz Director of Corporate Affairs Environmental Statement · Mainz site
