The fate of biobased and biodegradable cellulose-derived plastics in landfills represents an important topic from economic environmental points view. Anaerobic digestion is a cost-effective waste-to-energy technology. behaviour six polymer types—that is, cellulose (C), acetate (CA), viscose (V), nanocellulose (NC), textile (AT), heteropolysaccharide pectin (P)—was studied under anaerobic batch mesophilic conditions landfill leachate for 147 days. cumulative biogas production was as follows: C>V=CA>>AT>>NC=P. Metagenomic analysis revealed notable variations the proportion bacterial archaeal domains with highest abundance presence CA (80.2%) C (78.5%). At end digestion, cellulolytic, hydrolytic, dehydrogenase activities were measured intact samples, well liquid solid fractions, aerobic conditions. Cellulolytic activity P detected only pellet, while NC, mostly supernatant both Scanning electron microscopy confocal scanning laser showed defragmentation degradation polymeric substrates microbial colonisation. Based on results, appropriate biodegradation polymers; however, process specific.
