“…It was concluded, that the crosslinking of methyl cellulose hinders the biodegradation process [21]. Biodegradation of carboxymethyl cellulose has been studied using a fungal strain and according to the Organization for Economic Cooperation and Development (OECD) Test Guideline 301 A [22,23]. It was concluded, that CMC (DS: 0.7) can be expected to biodegrade completely in nature.…”

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

“…These metals together with chromium and nickel are also often present in industrial effluents. 62 It is important to confirm the potential environmental impacts of emerging commercial products like nanocellulose. The biodegradation of nanocrystalline cellulose (NCC) was compared with MCC by utilizing two anaerobic cellulosedegrading microbial consortia obtained from an anaerobic digester and wetland inocula.…”

Biodegradable polymers complement recyclable materials in battling plastic waste because some products are difficult to recycle and some will end up in the environment either because of their application or due to wear of the products. Natural biopolymers, such as cellulose, are inherently biodegradable, but chemical modification typically required for the obtainment of thermoplastic properties, solubility, or other desired material properties can hinder or even prevent the biodegradation process. This Review summarizes current knowledge on the degradation of common cellulose derivatives in different laboratory, natural, and man-made environments. Depending on the environment, the degradation can be solely biodegradation or a combination of several processes, such as chemical and enzymatic hydrolysis, photodegradation, and oxidation. It is clear that the type of modification and especially the degree of substitution are important factors controlling the degradation process of cellulose derivatives in combination with the degradation environment. The big variation of conditions in different environments is also briefly considered as well as the importance of the proper testing environment, characterization of the degradation process, and confirmation of biodegradability. To ensure full sustainability of the new cellulose derivatives under development, the expected end-of-life scenario, whether material recycling or “biological” recycling, should be included as an important design parameter.
