Small percentages can be big improvements and savings “ The reduction of our energy cost for steam Per unit processed material “ AAK Responsible growth | 27 Energy waste from steam production mainly FRPHVIURPÀXHJDVDQGHQHUJ\ORVWWKURXJK the outer surface of the boiler, especially if the boiler is old and has poor insulation. This was the case for the main boilers at our Aarhus site, so we started to measure and calculate where and how much energy was lost, and investigating the risks. Additional insulation Many boilers have natural circulation of the water inside the boiler which depend on the right temperature differences in the boiler. If the temperature differences are not correct then the boiler will stop working and most likely be ruined due to overheating. To make sure this was not the case, we bought in external specialists to help us, and they concluded that with an additional 200 mm of insulation there would be no risk. 99 percent of the outer surface had temperatures in the range of 40–110 °C, the last 1 percent of the surface had a temperature of 260 °C. Calculations showed that if this 1 percent of the surface was also insulated, it would increase the energy saving by 10 percent, so that was the measure that was taken. Heat sensitive photograph of a side panel with SRRULQVXODWLRQEHKLQG was calculated to be 1.3 percent. 6DYLQJVRI'..PLOOLRQ It took approximately four months to expand the insulation with 200 mm for each boiler. More than 100 pipes, valves, instruments and electrical wires had to be moved on each boiler to make room for the new insulation.

Today, legislation and markets aim to mitigate these changes by reducing the greenhouse gas emissions believed to be the driver of global climate change. AAK is playing its part. In 2013, AAK generated 251,000 MT of carbon dioxide at the production plants, which is 1.1 percent less than in 2012. 36 percent of direct carbon dioxide emissions stemmed from renewable resources. Carbon dioxide emissions from fossil fuel per MT processed decreased 18.1 percent compared to 2012. The ozone layer protects life on earth by ¿OWHULQJRXWVRPHRIWKHVXQ¶VKDUPIXO89 radiation. For that reason, any thinning of the ozone layer is hazardous. AAK works actively toward eliminating all equipment that uses RRQHGHSOHWLQJVXEVWDQFHV2'6ZKLFK are generally used for cooling.
