Diseño de un proceso industrial para la obtención de papel ecológico a partir del estiércol de ganado vacuno en la parroquia Dureno del cantón Lago Agrio

Abstract

The objective of this research is to design an industrial process for obtaining ecological paper using cattle manure as a raw material in Dureno Parish in Lago Agrio Canton. For this, the paper was obtained at the laboratory level that allowed the manipulation of the process variables. The papermaking process begins with the sterilization of manure with 4 hours of cooking at 150 °C, in pulping, sodium hydroxide concentrations varied between 10, 15 and 20% in relation to the input flow 0.258kg of manure and worked at 150 ° C with a variation of exposure time of 3h, 4h, and 5h; the extracted pulp is bleached with 10% sodium hypochlorite in a 2:1 ratio with respect to the volume of water used at a temperature of 65°C for 45 minutes, once the sheet of paper is formed it is pressed to remove excess water at 441kPa, in two sections the first for 5 minutes and the second of 2 minutes and allowed to dry for 72 hours at room temperature in the absence of light. The sheets have the characteristics of thickness 0.11mm, width 15.00mm, break length 180mm, maximum load 89.27mm, breaking resistance 5.95kN/m, breaking strength 5.95kN / m, elongation at break 3.32%. The optimal treatment is a1 with a yield of 69.82% this for having lower concentration of hydroxide and the minimum exposure time.
