The CoAct project enters the implementation phase

With a hybrid kick-off meeting on 8 and 9 November, the joint project in the BMBF funding measure "Stadt-Land-Plus" started its implementation phase.

How can residual biomass be processed into valuable activated carbon? This is what the CoAct project dealt with for three years, using the Lake Constance district as an example. The results of the research and development phase are four potential variants for the production of activated carbon from (residual) biomasses at four different locations, including a biogas plant, a building yard, a biomass disposal centre and a sewage treatment plant. Based on an economic and ecological evaluation and with the involvement of regional stakeholders, the operation of a CoAct plant in combination with a sewage treatment plant is particularly worth considering in the Lake Constance district.

After completion of the research and development phase, a two-year implementation phase will now follow, during which in-depth plant planning will be carried out using the example of the Kressbronn-Langenargen sewage treatment plant and for the Friedrichshafen-Weiherberg waste management centre. The tasks of the IfLS include evaluating the economic efficiency of the construction and operation of the plants and optimising them together with the plant planning. In addition, the IfLS deals with governance issues of plant operation.
