Revista Verde de Agroecologia e Desenvolvimento Sustentável, Mossoró, v. 8, n. 2, p. 52-57, abr./jun. 2013.1981-8203http://repositorio.bc.ufg.br/handle/ri/14790The aim of this work was to study economic viability for implementation of a system for collecting and drying the pulp residual potato in the processing line of potato chip, as well as its use in snacks with the but of the reuse of agroindustrial residue as new ingredient for the food industry. The payback method was studied, this is a direct valuation method, which calculates the number of years that will run the cumulative cash flows equaling the amount of the initial investment. The results obtained shown that company will save 19.8% wheat flour monthly, with the replacement of wheat flour by pulp washing residual dehydrated potato (PRLBD) in the processing of snacks. The payback for the purchase and implementation of a system for drying PRLBD will be paid in approximately 16 months. This study demonstrates that the project is viable from an economic standpoint, and contribute to reducing environmental impact and sustainability of the company, providing a correct destination for agro-industrial residues.porAcesso AbertoSolanum tuberosum L.Sustentabilidade agroindustrialImpacto ambientalSolanum tuberosum L.Environment impactAgribusiness sustainabilityArtigo
