Abstract Tobacco waste presents notable environmental challenges, such as soil and water contamination from nicotine other harmful chemicals, compounded by inefficiencies in conventional management. Converting tobacco into biochar offers a promising solution to address these issues. This study reviews the production, properties, applications of derived tobacco, using feedstocks stems, seeds, leaves, fines. It has been observed that stems are most commonly used precursor pyrolysis is frequently employed thermochemical conversion process, with yields ranging 5% 85%, depending on operational variables. Tobacco‐derived exhibits surface areas typically between 2 50 m /g, fixed carbon content 4 63 wt%, ash 12% 51%. applied agriculture, treatment, composting, energy demonstrating its efficiency. also plays an important role pollution remediation. Despite existing research tobacco‐based biochar, gaps remain gasification torrefaction biomass use tobacco‐related wastes like leftover cigarettes The findings this depict dual benefits utilizing for production – addressing disposal challenges while creating valuable material multiple economic advantages.

Abstract Liquid‐phase exfoliation, a technique for enhancing the properties of biochar, has been recognized as effective, circumventing limitations other methods such high expenses, scalability, and complexity. This study explored synergistic effect achieved by combining chicken feathers with elephant grass to create composite feedstock biochar production. The was subjected liquid‐phase exfoliation using acid acetone. Elemental analysis indicated that co‐carbonization combined biomass produced an enriched hybrid biochar. oxygen content in both routes (acid acetone) increased, increase decrease carbon acetone respectively. Textural revealed significant enhancement, surface areas acid‐exfoliated more than twice size pore volume exfoliated samples double Microscopic examination rougher, porous structures biochars comparison smooth, cohesive Functional group showed presence aromatic rings, carbocyclic group, alkene, suggesting potential applications adsorption. provides efficient method enhance properties, benefiting industries reliant on production utilization improving product quality, sustainability, environmental impact.

Abstract Biochar, a solid material derived from thermochemical process, has received significant attention due to its usefulness in various sectors. Previous studies have been conducted improve the properties and quality of this by altering processes, treating feedstock, hybridizing so forth, but little done on effect varying reactor's configuration. This research aims study stainless‐steel‐based combustion compartment volume biomass‐fueled top‐lit updraft gasifier groundnut shell biochar. The biochar yields for reactors ranged 34.9% 51.2%. sample produced smallest showed highest carbon content, according energy dispersive X‐ray spectroscopy (EDX) analysis. Potassium, another major element, decreased as was reduced. Scanning electron microscopy (SEM) analysis revealed that samples had an irregular shape rough surfaces, reducing resulted larger particles surface. Fourier transform infrared (FTIR) similarities differences peaks observed all samples. can find applications wastewater treatment, conversion storage, soil amendment, findings contribute design optimization biomass‐based gasifiers.

This study sheds light on the synthesis, properties, and application of plant husk-derived biomass into biochar through thermochemical conversion processes. Gasification, pyrolysis, hydrothermal carbonization, torrefaction are processes that have been used in this regard. Investigation production variables revealed temperature, carbonization duration, heating rate significantly influence yield characteristics husk-based biochar, including surface area porosity, with temperature exerting most notable impact. It was observed gave rise to a relatively higher than other processes, which may be due low temperatures usually utilized. The properties typically exhibit carbon content exceeding 45% its total weight. has applied as catalyst, for soil amendment, environmental remediation, water treatment. identification research gaps shows need further exploration intricacies well consequences socio-environmental factors, technical scalability, economic feasibility.
