Exhaust air purification

With fully biological exhaust air purification, which has been in operation since 1990, we can completely forego the use of chemicals.
This principle of this exhaust air purification is as simple as it is ingenious.

The exhaust air contaminated with odours is extracted from the production rooms, sent through an air cleaner for cleaning the exhaust air of dust particles and humidifying it. The exhaust currentis then sent through two Biofilters. Rising up through the filter material, the osmophores (odour particles) and other organic pollutants are degraded by strains of bacteria and other microbes. The purified air then enters the atmosphere.

The filter area of both bio beds is 1800 m².
The filter material consists of a mixture of fibrous peat and coconut fibre.

Waste water purification

The strict legal requirements made an extensive expansion of our in house sewage works necessary. This plant, which was started up in autumn 2001, is set up for 75,000 IV (inhabitant value), which corresponds to the waste water volume of a town with 75,000 inhabitants. This expansion ensures that the valid limit values of the waste water emission act for animal rendering are adhered to.
