Explosives plant
The major industrial establishment in the area is NITRON S.A., a company specializing in production of explosives. The company has a long history since its establishment in 1874 (then in Germany). There was a notable explosion in the plant in 1918, with numerous fatalities. The reconstructed Kruppamühle der Lignose Sprengstoffwerke GmbH employed 300 in 1929 and 750 in 1944. In 1934, the production was switched over to nitroglycerin and dynamite types of explosives.

Nowadays, the plant essentially consists of a system of bunkers in a forest, with strong walls but light roofs. It produces mostly explosives for applications in mining and civil engineering.
