GONZALEZ, M; GONZALEZ, E; AGUIRRE, P  y  CORSANO, G. Optimal Integration of Water Recycling Systems in Paper Manufacturing Processes. Inf. tecnol. [online]. 2004, vol.15, n.3, pp. 71-74. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642004000300011.

This work proposes a novel non-linear programming model that solves the problem of minimizing fresh water consumption in the paper manufacturing process, as well as reducing waste release. The degree of pollution of the flows to be recycled and the maximum contaminant composition treatable by different equipment units are determined; on the basis of this data, the maximum amount of recycleable residual flow is determined. The problem is modeled mathematically, determining the minimum consumption of fresh water, the maximum flow of waste water, the mass of fiber in suspension which can be recuperated, and the amount of pollutant to be removed in the process. It is concluded that the model used is a powerful generic systematic tool which can be used in any process for the reduction of residues
