Comparison of OilSeed Shell Biomass-Based Biochar for the Removal of Anionic Dyes-Characterization and Adsorption Efficiency Studies. Plants 2024, 13, 820. Abstract: This research investigated the synthesis of biochar through the direct pyrolysis of pre-roasted su...

Humic substances (HS) are originated from naturally decaying biomass. The main products of HS are humic acids, fulvic acids, and humins. HS are extracted from natural origins (e.g., coals, lignite, forest, and river sediments). However, the production of HS from these resources is not environmentally friendly, potentially impacting ecological syste...

Due to the population growth, there is an urgent need for sustainable technologies and products to address the imbalance between the availability of arable land and growing food needs. Increasing crop productivity in a cost-efficient and environmentally-friendly pathway is one approach to address this issue. In this study, lignin, a low-cost and un...

Acetic acid/formic acid/water (AA/FA/H 2 O, 50/40/10 ratio) was used to fractionate rice straw into lignin, hemicellulosic sugars, silica and dissolving pulp. In this paper, lignin separated from rice straw was utilized in the preparation of lignin-phenol-formaldehyde resins. AA/FA/H 2 O lignin was characterized as having lower molecular weight (M...

Four non-woods such as, dhaincha ( Sesbania bispinosa ), jute stick ( Corchorus capsularis ), wheat straw ( Triticum aestivum ) and corn stalks ( Zea mays ) were cooked by potassium hydroxide (KOH) at the optimum conditions of soda pulping. Dhaincha, wheat straw and corn stalks were delignified to kappa number 19.4, 13.6 and 19, respectively, while...

Dhaincha (Sesbania bispinosa (Jacq.) Wight) is a crop generally cultivated for improving soil quality. Due to the lack of forest worldwide, alternative source of raw materials for cellulose industries is the main concern today. In this investigation, dhaincha samples of 21 accessions were collected from different districts of Bangladesh in order to...

Bangladesh is an agriculture-based country. Rice straw is the main agricultural residue, which is easier to delignify in alkaline pulping, but difficult in processing due to high silica content. This paper describes a method of separation and fractionation of silica and lignocellulosic components in producing dissolving pulp. Rice straw was treated...
