Breaking down biodegradable bags

Article Abstract:

A study to determine the biodegradability of compostable bags within the normal composting process was undertaken. The findings showed that Envar, EcoPLA, Biocorp, MaterBi reSource and MaterBi Linden Group bags were completely decomposed whereas Bio-Solo, Plastigone and Degra-Novon bags were uncomposted. The tensile strength of the bags were also tested by filling each type with yard trimmings and was set on the curbside for two weeks. Among the bags which were fully decomposed, EcoPLA was the only bag which did not break.
