abstract = {The optimization of water management in industrial processes is paramount in diminishing
or mitigating, as far as possible, the negative externalities generated by its current use within the
linear economy model. This research presents methods for the optimization of wastewater from
paper mills which are associated with the new sustainability and circular economy model. In this
way, the concept of circular economy was applied to the wastewater treatment from a paper mill,
with the objective of recovering the resources contained in this type of effluent. The wastewater
treatment plant is based on a biological reactor of activated sludge, and treats a flow of 4868 m3.day-1.
This study proposes the development and evaluation of indicators of circular economy applied to
wastewater from a paper mill, as well as the assessment of the removal performance of color, total
suspended solids (TSS), biochemical oxygen demand on the fifth day (BOD5), and chemical oxygen
demand (COD), which are higher than 96% in all cases. Per 1 m3 of wastewater from a paper mill,
a volume of 0.9 m3 of potentially reusable water and a recovered sludge mass of 0.7 kg are generated;
the latter is reused as a mineral filler during the process itself. In light of this, a multivariable statistical
analysis was applied to determine the relationship of the operation variables and indicators of circular
economy. In this way, wastewater from the paper mill can be regarded as a technological nutrient,
which is partially reintroduced into the production process, enabling the recovery of the water and
mineral fillers that it contains.},
