Article Abstract
Lignocellulosic waste generation and their improper disposal has accelerated the problems associated with increased greenhouse gas emissions and associated environmental pollution. Constructive ways to manage and mitigate the pollution associated with lignocellulosic waste has propelled the research on biochar production using lignocellulose-based substrates. The sustainability of various biochar production technologies in employing lignocellulosic biomass as feedstock for biochar production not only aids in the lignocellulosic biomass valorization but also helps in carbon neutralization and carbon utilization. Functionalization of biochar through various physicochemical methods helps in improving their functional properties majorly by reducing the size of the biochar particles to nanoscale and modifying their surface properties. The usage of engineered biochar as nano adsorbents for environmental applications like dye absorption, removal of organic pollutants and endocrine disrupting compounds from wastewater has been the thrust areas of research in the past few decades. This review presents a comprehensive outlook on the up-to-date research findings related to the production and engineering of biochar from lignocellulosic biomass and their applications in environmental remediation especially with respect to wastewater treatment. Further a detailed discussion on various biochar activation methods and the future scope of biochar research is presented in this review work.

The conversion of biomass into chemical fuels is exciting but quite challenging in the development of an effective conversion strategy to generate easily-separated products without energy consumption. Herein, a lignocellulosic biomass-to-H conversion system via photo-thermal catalysis over MoC hierarchical nanotube catalysts in an acidic solution, in which the lignocellulose is hydrolyzed to small organic molecules (such as glucose, etc) by dilute HSO, and then the resulting glucose is oxidized by MoC catalyst to generate H are reported. During the photo-thermal catalytic processes, the carbon vacancy in MoC catalysts results in the generation of undercoordinated Mo sites, which act as active sites for both biomass oxidation and H generation reactions.

Palm kernel meal (PKM) presents a challenge for non-ruminant livestock feeding due to its high fibre content predominantly in the form of mannan. Microbial fermentation offers a sustainable solution for fibre hydrolysis in lignocellulosic biomass. In this study, a Bacillus subtilis strain (F6), with high mannanase secretion capability, was isolated from the environment.

Technical alkaline lignin (TAL)-based composite films have been developed for anti-corrosion applications, during which one-component solvents, including acetone and ethanol, were employed. The poor solubility of TAL in the abovementioned solvents undoubtedly resulted in inhomogeneous surface micromorphology and the consequent unstable performance. The present study provides a series of ethylcellulose/TAL (EC/TAL) composite films with uniform surface microstructure by using the 1,4-Dioxane/water binary solvent.

β-glucosidases (BGLs) are key enzymes in the depolymerization of cellulosic biomass, catalyzing the conversion of cello-oligosaccharides into glucose. This conversion is pivotal for enhancing the production of second-generation ethanol or other value-added products in biorefineries. However, the process is often cost-prohibitive due to the high enzyme loadings required.

Contamination of water bodies is a significant global issue that results from the deliberate release of pollutants into the environment, especially from mining and metal processing industries. The main pollutants generated by these industries are metallic wastes, particularly metals, which can cause adverse effects on the environment and human health. Therefore, it is crucial to develop effective and sustainable approaches to prevent their discharge into the environment.
