Conversion to powder coating at the Zumtobel brand's main plant in Dornbirn
New production processes have a beneficial impact on the environment and on costs
In 2007 the cataphoretic dip coating process for sheet metal parts at the lighting plant in Dornbirn was replaced by a new powder coating system.
In the past, solvents were added to paints and varnishes which were then sprayed onto the parts. In the powder coating process, paint particles are applied electrostatically. This dispenses with the need for waste air treatment with filter systems and afterburners. The volume of detergents required for cleaning the parts before coating has also been reduced.
The new powder coating process has meant that the volume of wastewater has been cut by 80%. Energy requirements in terms of power and heat are each down by 40%. 23 metric tons of hazardous waste per year are no longer generated. And in all, 40% of the CO2 emissions from the painting process, which equates to 500 metric tons a year, no longer occur. In terms of operating costs this means a drop of 58%.
