Biodegradation of green polymer composites: laboratory procedures and standard test methods

Green composites have gained attention as promising alternatives to the traditional ones, mainly for their potential biodegradability. They are a combination of biodegradable polymers with natural fibres. Frequently, a compatibilization of polymeric matrix and fibre/filler for improved green composites is necessary. However, the treatments can prejudice the biodegradability of the final material. As a consequence, biodegradation tests have to been carried out. For this reason, this chapter provides an overview of both the standardization methods used to determine a degree of biodegradation in different environments and the laboratory procedures commonly adopted. Moreover, it summarizes studies in the literature, published between the beginning of 2009 and May 2019, concerning the assessment of biodegradability of green composites.
