“…While pure cellulose readily degrades in good compost (97% degradation within 47 days), lignocellulose (e.g., agricultural residues and wood) does not degrade as readily. A recent review summarizes the mechanisms and different pretreatments that can be utilized for accelerating the biodegradation of lignocellulosic biomass . The compostability of different cellulose modifications to be used in material applications has also been evaluated in several papers through simulated composting experiments in the laboratory or by composting in real-composting facilities of different types.…”

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.

“…Lignin is usually more difficult to degrade than cellulose and hemicellulose, and is one of the most recalcitrant biopolymers in biology, mainly because of its complexity and heterogeneity [18c,56] . Generally speaking, lignin is hydrolyzed mainly through partial hydrolysis of aryl and alkyl ether bonds, cracking of carbon‐carbon bond, demethoxylation, alkylation, and condensation.…”

“…Generally speaking, lignin is hydrolyzed mainly through partial hydrolysis of aryl and alkyl ether bonds, cracking of carbon‐carbon bond, demethoxylation, alkylation, and condensation. Ligninase can be divided into two enzyme systems: lignin degradation enzyme and lignin auxiliary enzyme [12,56] . The auxiliary enzyme system mainly helps lignin‐degrading enzymes depolymerize lignin into dimers or monomers, including β ‐aryl ether enzyme, phenylcoumarinase, superoxide dismutase, quinone reductase, and peroxidase.…”

Lignocellulose biomass (LCB) has extensive applications in many fields such as bioenergy, food, medicines, and raw materials for producing value-added products. One of the keys to efficient utilization of LCB is to obtain directly available oligo-and monomers (e. g., glucose). With the characteristics of easy recovery and separation, high efficiency, economy, and environmental protection, immobilized enzymes have been developed as heterogeneous catalysts to degrade LCB effectively. In this review, applications and mechanisms of LCB-degrading enzymes are discussed, and the nanomaterials and methods used to immobilize enzymes are also discussed. Finally, the research progress of lignocellulose biodegradation catalyzed by nano-enzymes was discussed.

Accelerate the biodegradation of rice husks into compost requires a bioactivator. The bioactivator used is the effluent from a biogas reactor which integrates with the fermenter. The composting process for rice husk (Oryza sativa) adds a bioactivatorwith two treatments. Treatment A uses an effluent bioactivator Biogas reactor; treatment B uses an effluent bioactivator from the University of North Sumatra pilot plant. This study aimed to compare the effect of variations in composting treatment and B on the results of composting rice husks. From the results of the study, the two treatments at temperatures were not too much different; the average of treatment A was 330C, and B was 33.200C; the average value of pH in Treatment A was 7.1 and B was 7.3, while the average value of Content moisture in treatment A was 55.59% and in B was 55.16%. Meanwhile, the value of nutrients and macros is not too much different between treatments A and B. The organic C in A is 14.12%, and B is 14.36%. The N-Total value in treatment A is 1.08%, and B is 1.12%, the value of P2O5Ain0.77 and B is 0.69%, the valueAis 0.57% and B is 0.60%, the value of CaO in treatment A is 0.17%, and B is 0.22%, the value of MgO in treatment A is 0.29%, and B is 0.34, the value of Cu in treatment A is 9 ppm, and B is 9.1 ppm, the value of Zn in treatment A is 50 ppm, and B is 52 ppm.
