36 Resource efficiency projects – Energy AAK Louisville, Kentucky, USA Warehouse electricity reduction AAK Louisville currently operates a temperature-controlled warehouse in order to ensure quality consistency in all of its products. The warehouse experienced issues concerning air stagnation and excessive heat during summer months. In order to counter these issues large industrial fans which can improve air quality and also reduce energy consumption were installed. The project resulted in 97,500 kWh electricity reduction per year. AAK Dalby, Sweden Change of compressor The air compressor in Dalby has been replaced by two new compressors with recycling to heat up the building. The change from one to two compressors makes it more energy effective and more reliable. The energy saving is 83,000 kWh per year on recycling and approximately 60,000 kWh per year on energy. AAK Aarhus, Denmark More efficient electrical pumps AAK in Aarhus, Denmark has been saving electricity by focusing on inefficient pumps, electrical motors and reducing speed where possible. The energy saving is 800 MWh per year. AAK Montevideo, Uruguay Ice condenser In 2013 an energy efficiency project was started in order to replace the conventional ejectors in the deodorizing unit for vacuum generation by a dry condensing equipment. Besides reducing energy, this system has also the advantage of generating less effluents and reducing the amount of water used at the deodorizing unit. The ice condenser project was finalized in October 2015. The energy consumption of the deodorizing unit was reduced by 59 percent. Further, water consumption decreased by 59 percent and effluent generation decreased by 90 percent. AAK Zaandijk, The Netherlands Reduction of energy consumption Analyses have shown that a large amount of steam was consumed by tracing of pipes and tanks. Therefore a project was started to reduce the energy consumption by tracing with hot water instead of steam. Gas consumption was reduced by 10 percent. Resource efficiency projects – Air AAK Port Newark, New Jersey, USA H2/N2 project By reducing deliveries of liquid nitrogen with on-site gaseous N2 (GaN) production, AAK Port Newark’s carbon footprint was reduced. The average number of deliveries was reduced from 30 per month to 10 per month. Energy consumed for liquefaction is double the energy consumed to produce GaN. Total carbon footprint was reduced by 1,300 MT per year. AAK Hull, UK Mechanical vacuum systems The new deodorizer installed in Hull was designed to be more efficient in its use of energy compared to the one it replaced. Instead of simple steam vacuum generating equipment more investment was made in ice condensing technology and mechanical vacuum systems. The steam is generated by natural gas. CO2 emissions have been reduced by more than 1,000 MT per year.
