VALORACIÓN DE LOS RESIDUOS GENERADOS EN UNA PLANTA INDUSTRIAL DE PLASTICOS TANG S.A. DE LA CIUDAD DE DURÁN Y SU REÚSO COMO SUSTITUTOS DE MATERIAS PRIMAS.

Abstract

This study explores new non-hazardous waste management alternatives, specifically polyethylene terephthalate plastic powder and PET pulp which according to the amount of generation could be considered as special waste. The generation of this type of waste was evaluated in the company Plastics Tang S.A. During one month, company cataloged as manufacturer of plastic containers. The amount of raw material (inputs) used for the production of plastics, together with the waste of dust (output) that is generated after the production are the main material to look for management alternatives. The presence of plastic waste deposited without any type of segregation, valuation and reuse in the dumps has increased, reducing the conditions of environmental quality and selfpurification of the soil. Of the 11,341 tonnes per day of non-hazardous waste generated in Ecuador,plastic represents 11%. When the waste is valued, new alternatives could be suggested to reuse the plastic powders previously considered, reusing raw material and finally contributing to the reduction of environmental impact. Key Words: Polyethylene terephthalate, recovery, recycling, reuse, management, waste.
