dc.description.abstract | The main objective of the study was to determine the biochemical and physical conditions of two different types of polymeric materials (HDPE with oxo-additive and PLA) when subjected to conditions similar to those presented inside a sanitary landfill. These materials are commercialized within the country claiming to be biodegradable under certain conditions. However, the conditions in which such degradation may occur are completely unknown from those presented inside s solid waste final disposal site (sanitary landfill). The experiment simulated the general conditions to which the materials would be subjected once inside a sanitary landfill, (absence of molecular oxygen, absence of light, constant temperature, high humidity, among others). Changes in biochemical and physical conditions were monitored as well as the container. These changes may indicate degradation of the polymers. Along the experiment, not enough evidence could be observed that doubtlessly showed actual biodegradation in any of the plastic materials tested. | eng |

Estos materiales se comercializan en el país afirmando ser biodegradables bajo ciertas condiciones. Sin embargo, las condiciones en las que puede ocurrir dicha degradación son completamente desconocidas a las que se presentan dentro de un sitio de disposición final de residuos sólidos (relleno sanitario). El experimento simuló las condiciones generales a las que estarían sometidos los materiales una vez dentro de un relleno sanitario, (ausencia de oxígeno molecular, ausencia de luz, temperatura constante, alta humedad, entre otras). Se monitorearon los cambios en las condiciones bioquímicas y físicas, así como en el contenedor. Estos cambios pueden indicar la degradación de los polímeros. A lo largo del experimento no se pudieron observar evidencias suficientes que mostraran, sin lugar a dudas, una biodegradación real en ninguno de los materiales plásticos ensayados. | spa |
