          Abstract

          El objetivo de este estudio es evaluar de manera preliminar si materiales denominados "verdes" o "biodegradables" son degradados satisfactoriamente en sistemas de composta con lombriz a pequeña escala. La mayoría de dichos materiales se elaboran con derivados del papel o con biopolímeros naturales, de los cuales el más común es el ácido poliláctico (PLA). Para el estudio se sometieron a distintas pruebas cuatro artículos desechables etiquetados como biodegradables hechos de los siguientes materiales: bagazo de caña de azúcar, PLA, papel recubierto por PLA y polímero de maíz. Los resultados mostraron que el PLA, el papel recubierto por PLA y el polímero de maíz no presentan una degradación adecuada en estos sistemas. Esto se atribuye a que no se tienen las condiciones necesarias para iniciar la hidrólisis que el biopolímero requiere para disminuir su masa molecular y hacerlo susceptible al ataque microbiológico y/o a la digestión por lombriz. En cambio el material de bagazo de caña de azúcar mostró un desempeño positivo en la prueba.

          The objective of this study is to conduct an initial test of whether green disposable products satisfactorily degrade in small-scale vermicomposting systems. Most of these materials are made of paper/cardboard or natural biopolymers, being the polylactic acid (PLA) the most commonly employed. Four disposable green products, made of sugar cane fiber, PLA, paper covered with PLA and corn polymer, respectively, were tested. Results showed that disposable items made of PLA, paper covered with PLA, and corn polymer do not satisfactorily degrade in this kind of systems. This is mainly due to not having the ideal conditions for biopolymer hydrolysis, molecular weight reduction, and subsequent microbiological attack and/or worm digestion. However, the sugar cane fiber material had a positive performance in the test.
