Raw materials: Environmental protection in the Radeberger Gruppe begins with the selection of raw materials. Since the end of the 1980s, therefore, we have ensured that the raw materials were not being treated with preservatives. In order to dose our precious raw materials precisely and minimise wastage, every stage of the production process is computer-controlled. Continuous monitoring mechanisms ensure constant process optimisation. Energy consumption: It goes without saying that the Radeberger Gruppe's production and administration facilities take the most energy-efficient approach possible. The waste heat in the steam generated while boiling the wort is, for example, reclaimed by kettle vapour condensers for reuse in subsequent stages of the process. The heat generation plants in the breweries are state of the art and are regularly tested and maintained. Intelligent operating models minimise load spikes and optimise consumption. Dust emissions: Dust is generated in the breweries both during delivery of the raw malt and in its preparation in the malt mills prior to the brewing process. By building in complex filter systems, however, these emissions are kept within the statutory limits and disposed of separately. Water: Beer is a pure foodstuff, and hygiene, including the regular disinfection of all plant, tanks and containers, is therefore particularly important. By reusing rinse water, installing water-saving nozzles, providing employee training, optimising machine programmes and minimising the disinfecting agents used, the Radeberger Gruppe has managed to reduce both its fresh water consumption and its waste water charge considerably over the past few years. Here, too, the continuous development of gentle and resource-saving processes is guaranteed. Recycling: Beer draff and yeast: 100% of the draff accumulating from the beer-brewing process is recycled into agricultural feed. Yeast reclaimed from the production process is also used as a protein and vitamin source in agriculture. Filter consumables: the use of insoluble filter consumables, such as diatomite, in the brewing process has been continually reduced and refined through ongoing process optimisation at the Radeberger Gruppe sites. The remaining wastes accruing from this substance are recycled in agriculture as soil additives. Packaging: materials used (labels, crimp-tops, adhesives etc.) are delivered in large, purpose-built containers which are integrated into a closed-loop deposit system. Broken glass and old labels are collected separately and likewise 100 percent recycled. Noise: Noise emissions are produced in the breweries by bottle conveyors, pumps, mills, and silos. Enclosing noisy equipment and utilising sound-absorbing ceilings and walls /windows or new materials (such as plastics in conveyor belts, for example) has helped to further reduce emissions.
