Estudio de la biodegradación de bolsas oxo - biodegradables utilizando compost maduro seco, con aireación y simulando condiciones ambientales de humedad y temperatura de un relleno sanitario ubicado en la costa ecuatoriana.

Abstract:

This work allowed the study of the biodegradability of four types of oxo - biodegradable bags used to sell products, simulating environmental conditions of a landfill located in the city of Manta. It started from a field study involving the characterization of large chains selling products in the city; we proceeded to the collection and selection of 4 samples of bags with greater impact of consumption. Which were subjected to solar radiation for two months, then the samples were seeded in different substrates and conditions of temperature and humidity was simulated for 3 months in a bioreactor. The quantification of biodegradation is carried out by assessing the physical, mechanical , thermal and spectroscopic properties , where by it was found that the samples subjected to testing showed an onset of biodegradation where there was decrease in the molecular weight , thickness and tensile strength , formation carbonyl groups by oxidation and constant melt temperature.
