Análisis de residuos lignocelulósicos provenientes de procesos agroindustriales de la región del Cauca con potencial para el desarrollo de polímeros biodegradables
<p>Entre los principales problemas socio-ambientales de la actualidad se destacan, la dependencia de los recursos fósiles y la disposición de residuos, que han llevado a la instauración de reglamentaciones y/o políticas públicas, para mitigar los impactos producidos por estos. En este sentido, vale destacar que los residuos lignocelulósicos son considerados como una de las materias primas renovables más abundantes y promisorias a nivel global. De esta forma, el aprovechamiento parcial, o incluso total, de los residuos agroindustriales lignocelulósicos, no solo es una ventaja desde el punto de vista ambiental, sino que también podría resolver algunos problemas económicos. De hecho, esto puede conducir a la minimización de la disposición de residuos mediante el tratamiento o la gestión de estos y al desarrollo de bioproductos con alto valor agregado basados en los sistemas de economía circular.</p>
