Their challenge

Deutsche Gasrußwerke were producing a significant amount of surplus for their carbon black production, primarily for the tire industry. But how could they turn that excess heat into something useful?

Extraordinary Thinking

A sustainable alliance was the answer. We looked for a perfect match: a company that could benefit from the excess heat, willing to expand to the greenfield around the corner. We found the Coldstore Group, who were in need of additional energy to keep their refrigeration going. By working together with the City of Dortmund, our experts can help Gasrußwerke and Coldstore achieve their objectives in an efficient way.

Imaginative Solutions

Our system recycles excess heat from the Gasrußwerke plants and converts this into cooling for Coldstore. In addition, the solution increases the attractiveness of the "Cleanport" technology location at Dortmund's industrial harbour with a new player on the ground.

The difference

The solution intelligently combines supply and demand. It turns wasted heat into spending power for Gasrußwerke by providing an additional revenue stream and allows Coldstore to benefit from low-cost energy while reducing their CO2 emissions and running costs. A great partnership, a great example of recycling surplus energy.
