With the Environmental Technology Award, the Baden-Württemberg Ministry of the Environment, Climate Protection and the Energy Sector recognizes outstanding innovations in environmental technology in a total of four categories. Dürr impressed the jury with its solvent recovery in the ‘Material Efficiency’ category and with its software for air pollution control systems in the ‘Measuring and Control Systems, Industry 4.0’ category.
Dürr sees the nomination of its two products as a recognition of the development work it has been undertaking for many years now, and not only in environmental technology. “Through our innovative technologies, we want to help our customers reduce their environmental footprint,” explains Dr. Jochen Weyrauch, Deputy CEO of Dürr AG and responsible for sustainability on the Board of Management. “At the same time, we want to be proactive in fulfilling our responsibility toward the environment.”
In the production of lithium-ion batteries, which is the key technology in electromobility, a number of different solvents are used in the coating system. Thanks to Dürr’s novel technology, these solvents can be removed from the exhaust air and 99 percent of them can be recovered. Without this recovery, the generated exhaust air would have to undergo a thermal purification process, generating additional CO2 emissions. Dürr’s solution thus contributes to savings on solvent purchasing. This reduces production costs and is also very resource-friendly.
The software that is nominated for the Environmental Technology Award is mainly used in air pollution control systems or systems for decentralized generation of electricity. It enables operators to prevent faults or resolve problems faster in case of emergency. The software can be used in upgrading old systems, thus making them suitable for data analysis and remote access. This leads to less downtime in production. Service engineers can resolve most faults without having to be on site, which reduces response times and saves many tons of CO2 that would otherwise be generated during business trips.
“The determination and tenacity with which companies are contributing to sustainability and environmental protection through the use of resource-efficient processes and products is impressive,” says Thekla Walker, Minister of the Environment in Baden-Württemberg.
