The organic fraction of municipal solid waste (OFMSW) should be subjected to anaerobic digestion (AD) to produce methane, a sustainable energy source. Many nations use anaerobic digestion to process food waste that has been segregated at the point of origin. However, the existence of plastic bags is a huge impediment. This research evaluated the anaerobic degradation of several bioplastics, aimed at possible usage as compiling bags for the OFMSW. The biodegradation of the bioplastics was influenced by the AD process' microbial community composition and bioplastics' chemical content. Some biopolymers, such as poly(hydroxyalkanoate)s, starch, cellulose, and pectin, may be destroyed at the hydraulic retention durations often utilized at biogas facilities. Therefore, there is no risk of contamination. Biodegradable polymers have been developed to address this problem. Composting and soil decomposition are the most common methods for conducting degradation investigations. There are certain benefits to anaerobic digesting, such as producing methane-rich biogas that may be utilized as a fuel over aerobic digesting. Anaerobic digestion has been hampered by the presence of plastics. This research aims to determine if thermoplastic starch, a material manufactured from starch, can degrade under anaerobic conditions. The experiment was carried out in a 37 °C wet digestion batch setting with 30 and 90 days retention durations to collect data. Anaerobic digestion plant digestate from Mustankorkea was utilised as inoculum, while unused food from Ylistö eatery was used to give nutrients to the bacteria. Samples included thermoplastic starch, polyethylene terephthalate (PET), and paper. A visual inspection of the materials and a comparison of mass loss and the quantity of biogas generated from the theoretical maximum were used to measure degradability.
