As early as 2017, the team began drastically reducing its own greenhouse gas emissions. Up to that point, two 500-kilowatt gas heating tanks were used to produce the necessary thermal energy. Warzecha’s team shut down both boilers and switched over to district heating. The procured 1500-kilowatt heat exchanger now offers sufficient reserves even if the plant is expanded. This switch reduced the heating costs by 25 percent, on the one hand; on the other, instead of releasing the malodorous gas generated in the neighboring coke industry as a waste product directly into the atmosphere, the district heating supplier burns it, thus preventing the bad-smelling gas from reaching residents in the area. This is another way the ZF plant is making a small contribution to the well-being of society. “When it comes to reducing greenhouse gas emissions, we have far exceeded the 20-percent target. In the meantime, we have locally reached zero,” says the hands-on project manager with a smile.
