Previous work within this project has shown that cellulose has a very complex degradation kinetics which is_x000D_
much slower than other compounds in typical domestic wastewaters. Given this difficult degradation, cellulose_x000D_
is an important contributor to sludge production in wastewater treatment plants and can as such present an_x000D_
important limiting factor on a plant's capacity. Removal of cellulose in a pre-treatment step by sieving with a_x000D_
Rotating Belt Filter (RBF) shows great potential to increase the performance of wastewater treatment systems_x000D_
while keeping investment and space requirements low. Moreover, the solids that are retained by the RBF can_x000D_
be recovered for either reuse or conversion to energy. However, in order to make decisions on proper_x000D_
installation and operation of an RBF pre-treatment, more detailed, qualitative information on the fate of_x000D_
cellulose in a treatment plant is needed and the specific biodegradation dynamics of cellulose need to be_x000D_
investigated further._x000D_
So far, cellulose degradation could only be investigated in an indirect way due to the lack of a valid analysis_x000D_
method to directly measure the concentration of cellulose in wastewater and sludge samples. However, a new_x000D_
analysis method allowing for direct cellulose measurements has recently been developed thus opening up new_x000D_
perspectives for the analysis of the cellulose degradation mechanism. It is the goal of the Engage plus project to_x000D_
combine this novel analysis method with traditional biodegradation experiments for a more direct analysis of_x000D_
the fate of cellulose during its degradation as well as detailed characterisation of the cellulose content in_x000D_
incoming wastewater. The combined knowledge of degradation rate and proper influent fractionation can_x000D_
subsequently be used in a detailed modelling study to support the industrial partner in decision making_x000D_
