1. IntroductionBiodegradable polymers broaden the range of waste management treatment option over traditional plastics and this issupported by the Life Cycle Assessment. The most favored end-of-life disposal options for these materials are domestic and municipal composting instead of landfill which is the worst disposal option. Therefore, biodegradable polymers can make significant contributions to material recovery, reduction of landfill and utilization of renewable resources (Davis and Song, 2006). Because of the difficulty in recovering the conventional polyethylene mulching film after its use, biodegradable films have been developed and commercialized. These are films (usually made of bio-based materials) which, after their use, can be buried in the soil along with the plant remains in order to be decomposed by microorganisms (Demetres et al., 2013).
