Sustainable energy usageBAMBERGER MÄLZEREI and its subsidiary DONAU MALZ in Neuburg an der Donau have always equated a sustainable energy policy with forward-looking energy management. Tens of millions have been invested in energy efficiency measures in the last two years. Natural gas powered co-generation plants for power and heat generation that operate twenty-four-seven year round have been installed in Bamberg as of 1989 and in Neuburg as of 1991, in addition to gas boilers. They have an electrical capacity of 3 x 210 kW (Bamberg) and 4 x 210 kW (Neuburg) and a thermal capacity of 3 x 360 kW (Bamberg) and 4 x 360 kW (Neuburg). In order to optimise this environmentally friendly production process even further in the direction of sustainable energy management, the management have decided to replace the existing gas boilers. In Bamberg, construction of a heating installation using forest chips as fuel was chosen as the most efficient alternative while in Bamberg, the choice was in favour of connection to the new district heating network. With these future-oriented solutions, BAMBERGER MÄLZEREI uses 11,000,000 kWh and DONAU MALZ 25,000,000 kWh annually, without an environmental impact. In both plants, state of the art production facilities including recuperation are currently installed.
The energy savings resulting from construction of new kilns and additional energy-related measures at both locations led to a reduction of total gas consumption of 42% in Bamberg and of 35% in Neuburg (see Fig. 1).
Such sustainable energy supply based on major reduction in use of fossil fuels considerable lowers emissions. Annual carbon dioxide emissions dropped by 2547 tons at BAMBERGER MÄLZEREI and by 3302 tons at DONAU MALZ (see Fig. 2).
Construction of the new forest chip heating plant in Bamberg and connection to the district heating in Neuburg was also targeting at cross-generational energy solidarity. The continuous improvement process of the energy management system ensures that the contribution to the energy turnaround becomes increasingly larger. In order to further optimise resource-conserving, sustainable production, an environmental management system in accordance with DIN EN ISO 14001:2009 was introduced simultaneously with the energy management system. Both plants were certified in May 2014.
