New Exhaust Air Concept for Surface Technology

“We save resources, protect the environment and work in harmony with humans and the environment.” At BUTTING, we also follow these guiding principles of our self-image in our investments into the areas of production. Statutory regulations, official requirements and the guidelines of the DIN EN ISO 14001 have long since been our minimum standards and we exceed them whenever possible. This is how the expansion of the pickling basins in surface technology led to the special significance of environmental protection and with it, exhaust air treatment.

Chemical pickling is, just as it always has been, the most common and best technique for making the surface of stainless steels resistant to corrosion. At BUTTING, tubing and shaped pieces are generally pickled to give them a clean, metallic surface after processing. For this production process, BUTTING has various pickling areas and baths at their facility in Knesebeck.

In recent years, the production capacity for the fabrication of tubing has been increased significantly in Knesebeck. Consequently, the surface technology capacities needed to adapt to the increased output quantities.

The new pickling basins were built in close proximity to the already existing facilities. Presently, the investment team is planning the installation of a new facility for exhaust air treatment. The necessary alteration permits are being drawn up in consultation with the trade supervisory board according to the German Federal Immission Control Act (BImSchG). After receiving official approval, these investments shall be implemented right away and the facility will be constructed by a specialized company in accordance with the regulations of the Water Resources Act.

In doing so, the planned exhaust facility for tubing pickling uses the existing roof openings. Suitable measures will reduce the projected noise emissions of various areas of the facility to at least the prescribed limits.

Werner Peesel, BUTTING’s Environmental Management Representative, explains the objective: “By taking environmental aspects into consideration in the production and process engineering development processes, we are sustainably improving the environmental compatibility of our production.
