A multitude of materials is used in production in industrial companies. This almost always includes those that present a certain hazard, since they may pose a risk to human health or the environment if used improperly. In production at Gira, this predominantly involves cleaning and lubricating agents, caustic solutions, acids and solvents. Careful treatment of these substances is therefore strictly obligatory.

Nevertheless, those who consciously assume responsibility for people and the environment have an even higher objective. "For us, it's about avoiding or at least limiting – as far as is possible – the use of hazardous substances. At Gira, we place paramount importance on this. This is why we also discuss it with our suppliers and actively broach the subject," says Gerrit Lotz, Head of Safety and Environmental Protection. "It is important to keep this topic in mind even at procurement – after all, new materials are being developed all the time that may be less problematic." Through awareness and responsible action, problematic materials can be replaced by less harmful or even completely hazard-free materials. This signifies success for Gira, its employees and the environment.

Gira already implemented a key innovation in 2004. Since then, no biocides have been used in production. Previously, as was common practice, biocides were used to prevent germ formation in the cooling circulation systems. This ensured that the towers for cooling water remained sterile. Since the installation of a centrifuge in 2004, however, this has become unnecessary. This device's movement physically destroys any alga that forms in the cooling circulation system and promptly tears away any undesired accumulations. The system operates flawlessly, is low-maintenance and therefore presents even more advantages. Overall, this means less hassle, lower costs, and of course, less stress on the environment.
