Over the past five years, Freudenberg has reduced its annual CO2 footprint at the site from over 17,000 tons to some 600 tons. A switch to electrical energy generated entirely from water, wind and solar power has helped. New roof insulation reduces the necessary district heating in the maintenance hall. LPG liquid gas has replaced fuel oil in the air purification system’s burner. “We have also improved efficiency in the manufacturing process,” says Lindell.
One example: The pores of the sponge cloths which absorb liquid, are made using Glauber’s salt, which is introduced into the fabric during the production process, crystallized with cooling, melted and then washed out again. The salt is 100 percent recycled saving some 1000 tons of the raw material every year. Since 2015, the amount of industrial waste has been reduced by about 40 percent. And a new wastewater treatment plant is expected to bring further environmental benefits in the future.
