6. Future research needs
Currently, composting is considered as one of the most suitable
approaches for disposing solid FW. However, the final product of
FW compost should be of high quality in order to guarantee its
marketability. Our ultimate goal is to obtain desired final product
while the operation cost would be as cheap as possible. However,
the possibility of accomplishing this goal is affected by many complexities
that exist in the processes. In the following sections, potential
directions that may be useful for better understanding the
insights of FW composting processes will be discussed.
