    Evaluación de la capacidad de biodegradación de contenedores fabricados a partir de recursos agroindustriales infrautilizados de la industria bananera

    According to the United Nations, approximately 430 million tons of plastic are produced each year. Consequently, this waste represents 85 percent of the total contamination in bodies of water, 36 percent of which are disposable containers. To combat this problem, resources have been focused on the research of more environmentally friendly materials. In Ecuador, banana, due to its high production and waste generation, emerges as one of the best alternatives for the development of bio containers to replace single-use plastics. For this reason, this research evaluated the biodegradation capacity of containers made from underutilized agro-industrial resources of the banana industry. For this purpose, a buried test was carried out with samples of biodegradable banana containers (CBB) in agricultural soil for 15, 30, 45 and 60 days, where values of up to 52.53 percent biodegradation based on dry weight were obtained. On the other hand, in vitro biodegradation capacity was evaluated by inoculation of Aspergillus niger, where it was demonstrated that this strain prefers CBB as a substrate, compared to filter paper and single-use plastics, due to the greater availability of nutrients for its growth. Finally, through microbiological analysis and bibliographic research, it was demonstrated that the shelf life of CBB is equal to or greater than 60 days, since their physicochemical and usability characteristics are not compromised during this period.
