The project for the implementation of the remediation targets for the total exhaust air of Flumroc AG at the production site in Flums (SG) provides for the construction of new waste gas purification plants. At the same time, conversions and optimizations are also planned in the production process. As a result, the production of stone wool will become more energy-efficient and, in addition, CO2 and SO2 emissions can also be significantly reduced. Thus, the project will lead to a significant environmental improvement compared to the initial state.
