incineration (Hemphill, 1993) and landfill deposition (Clarke,1996). However, these practices have some disadvantages, mainly related to disposal costs (Clarke, 1996). At all, the continuous increase of plastic film consumption led to the serious waste prob - lems and soil pollution that we are facing nowadays. To overcome these environmental impacts, the introduction of biodegradable mulches represents a really promising alternative to the PE films promoting a sustainable and environmentally friendly solution forthe agricultural activity. At the end of their lifetime, these new materials have the advantage of being incorporated directly into the soil or into a composting system and undergo biodegradation by soil microorganisms (Moreno and Moreno, 2008).
