Abstract

The pursuit of a circular economy has led to the introduction of finescreens in Waste Water Treatment Plants (WWTP). The high cellulose content of the fine sieve material (FSM) collected in the screenings of domestic waste water (Ruiken, Breuer, Klaversma, Santiago, & van Loosdrecht, 2013), shows the promise of being enzymatically converted into glucose. However, this process is currently economically unfeasible, were the enzyme costs are considered to be a major barrier (Liu, Zhang, & Bao, 2016). In an attempt to design a method in which the enzyme usage is limited to reach economic feasibility, immobilization by cellulose binding domains and dialysis membrane were evaluated. By performing a market evaluation an estimation on the potential market size and possible production was made, which led to a cost price of € 200.00 per metric ton of glucose. To determine the cost price for glucose derived from FSM, a cost analysis on a production facility with a potential annual production of 10,000 ton of glucose was made. With a cost price of € 365.68 per ton of glucose, economic feasibility was not reached. However, potential further research on the composition of FSM shows the promise of reducing the cost price to € 225.84, which might be sufficient to reach economic feasibility.
