Sludge is a large part of the waste. Therefore a lot of time and money is invested in turning sludge into a useful raw material. In 2018 this led to testing with a small testing installation. With this installation proof is delivered that sludge can be turned into a basic raw material. After re-engineering in the end of 2018 a prototype could be build. The sludge drier should simplify the processability. The sludge drier is operational as we speak although effort is put into several optimalisations. By reducing the scent, noise and safety a continous process is possible.
The installation then guarantees the reuse of our sludge
