Heating without emissions

The new office building at CTT is heated by surplus heat from the Köhlbrandhöft sewage treatment plant, which lies in close proximity to the container terminal. Such cooperation is advantageous for both parties; the utilization rate of energy generated by the sewage treatment plant is boosted whilst providing a cheap energy source for the container terminal.

There are also distinct ecological benefits. To produce the required 2 million kilowatt hours of energy required, large quantities of fossil fuels would be burnt, creating 1000 tons of carbon dioxide.

“Today, we already cover the sewage treatment plant’s energy needs for sixty percent with energy gained from the sewage process itself. Due to the heat supply installed in Container Terminal Tollerort, we can use the sewage sludge even more efficiently”, says Dr. Michael Beckereit, CEO of Hamburg Water. Hamburg Water and HHLA received part of the finance for building the 1.5-km of hot water pipes and emission-free heating of the CTT building from the Hamburg Ministry of Urban Development and the Environment (BSU) under the Hamburg Senate (state government) programme “Companies Conserving Resources”.
