Aplicación de un proceso biotecnológico para la degradación de acetato de celulosa de colillas de cigarrillo usando Pleurotus Ostreatus

This research addresses the development of a biotechnological process for the degradation of cellulose acetate present in cigarette butts, classified as one of the most abundant and polluting wastes worldwide. In order to do this, the fungus Pleurotus ostreatus was used, which is already previously recognized for its great capacity to degrade lignocellulosic compounds. The main objective was to analyze the available alternatives to have an adequate management of the waste, having as a main focus the biotechnology part that manages to contribute to the mitigation of the great environmental impact produced by these toxic wastes, the cigarette butts. Within the methodology, the evaluation of different initial treatments is included, such as crushed cigarette butts, whole cigarette butts, pretreated with NaOH and mixtures with bran. Each treatment was tested for pH, percentage of acetyl groups and the measurement of weight loss before and after the process. Preliminary analyses show that the pretreatment that favoured the activity and growth of the fungus was the one that had bran with a degradation percentage of 21.06%, which allowed the optimisation phase to continue by varying the temperature conditions and proportions of bran and cigarette butts.
