In this study, we investigated the enzymatical degradability and pilot-scale composting of 14 cellulose-based materials. The materials analyzed here were cellulose regenerated from ionic liquid (EMIM[OAc]), carboxymethyl (CMC) crosslinked by aluminum salt (Al-salt), methyl cellulose, acetate, butylated hemicellulose: DS: 1, 0.4, 0.2, cellophane, wet strength paper, nanocellulose, paper partially dissolved IL, carbamate, palmitate, octanoate. aim study was to show how chemical substituting substituent itself influence biodegradability enzymatic degradation these films shows correlation between hydrolysis rate degree substitution. decreased exponentially as substitution increased. Modifying extent that it gains needed obtain good mechanical properties, while retaining its natural is an important factor when preparing alternatives for plastic films.
