The electricity and heat generated in this way would be used to supply the ZKW with this energy. This is another important point in favor of a sewage sludge incineration plant. This would ultimately enable the sewage treatment plant to become "self-sufficient," which would also ensure fee stability. And to avoid additional costs and taxes (e.g., grid fees), it makes sense to install the plant directly where the energy can be delivered immediately. This ensures long-term planning security and price stability for the sewage treatment plant operation and thus also for the fee payer.
