It should be stressed that the purpose of the paper is to discuss a
topic that is not adequately described in the literature, even if
water-use-related topics are becoming more and more important
considering the challenges posed by climate changes. The paper
shows that a reduction of the consumption of fresh water and of
the related production of wastewater is possible without any
structural modification of the WtE plant and, at the same time,
evaluates the economic feasibility of the reuse approaches.
