The management of solid waste is a growing concern in many countries. Municipal solid waste is a major component of the total solid waste generated by society, and the composting of municipal solid waste has gained some attention even though a composting treatment for it is not yet widespread. One reason for this is that composts made from municipal solid waste tend to contain significant quantities of plastics. It may not be realistic to replace large portions of these plastics with biodegradable materials, and it may be more important to separate plastics unsuitable for the composting process at the generating spots. However, for food packaging, there is still a great deal of interest in using biodegradable plastics that are difficult to sort at the generation spots. Under these circumstances, nanocomposites of biodegradable polymers as matrix and clays, that can be degraded along with organic wastes during composting have been developed. This work aims to investigate the biodegradability of several biopolymers in presence microorganisms (solution and compost). The collected samples were characterized by several techniques to follow the biodegradation processes and temperature effect. The results obtained allowed to make correlations between temperature and polymer structure.
