This project aims at the evaluation of eight various routes that potentially may allow wastewater treatment plants to produce less sludge (from 5% to 100%). It has been possible to define several routes that could be applied efficiently with knowledge of possible side-effects (risk management) and an estimation of associated costs (OPEX/CAPEX), which are quite comparable to those used in conventional sludge treatment and disposal.
