The increase in sludge generation in wastewater treatment plants (WWTP) makes sludge management a difficult task so that it is necessary to create alternatives for the final sludge disposal. The mineralogical characteristics of the sludge allow it to be applied to construction materials. The construction industry is the one that most exploits and consumes natural resources and uses energy intensively, thus generating quite considerable environmental impacts. Creating sludge utilization techniques in the construction industry provides a safe and stable destination for sludge and contributes to reducing the environmental impacts that the construction industry already has. Thus, the general objective of this project is to evaluate the technical feasibility and economic valuation of the use of WWTP sludge for partial replacement of cement in the production of mortar.
