Multifaceted Characteristics of Biochar and Its Implementation in Environmental Management in a Sustainable Way

Environmental Quality Management, Journal Year: 2024, Volume and Issue: 34(1)

Published: Aug. 16, 2024

ABSTRACT Biochar (BC), a carbon‐dense substance created through the pyrolysis of organic biomass, has garnered considerable interest as promising option for sustainable mitigation methods. A comprehensive examination diverse attributes BC and its implications addressing contemporary environmental issues while fostering practices is compiled in this review. The synthesis techniques structural are scrutinized initially, emphasizing remarkable features such broad surface area, porosity, active sites. These characteristics conducive to myriad applications, including pollutant remediation, soil health enhancement, carbon sequestration. Subsequently, review delves into mechanisms underlying BC's effectiveness remediation. exhibits augmented adsorption capacities, catalytic functionalities, interactions with microorganisms, facilitating removal contaminants from different matrices environment. Recently, their products nano‐BC have gained widespread recognition feasible material. Fabrication, characterization, modification, applications were also discussed detail. Its integration agriculture holds promise enhancing matter, augmenting production, mitigating gas emissions, thereby contributing food security climate change mitigation. In conclusion, emerge avenue challenges advancing development objectives. However, further research warranted optimize methodologies, elucidate long‐term implications, facilitate scalable production adoption.

Effect of Flax By-Products on the Mechanical and Cracking Behaviors of Expansive Soil

Materials, Journal Year: 2024, Volume and Issue: 17(22), P. 5659 - 5659

Published: Nov. 20, 2024

Expansive soils, prone to significant volume changes with moisture fluctuations, challenge engineering infrastructure due their swelling and shrinking. Traditional stabilization methods, including mechanical chemical treatments, often have high material environmental costs. This study explores fibrous by-products of flax processing, a sustainable alternative, for reinforcing expansive clay soil. Derived from the Linum usitatissimum plant, fibers offer favorable properties benefits. The research evaluates impact tow (FT) reinforcement on enhancing soil strength reducing cracking. results reveal that incorporating up 0.6% randomly distributed FTs, consisting technical shives, significantly improves properties. unconfined compressive (UCS) increased by 29%, FT content, reaching 525 kPa, compared unreinforced further additions, which led decrease in UCS. reduction is attributed diminished soil–fiber interactions fiber clustering. Additionally, tows effectively reduce crack length density (CLD) decreased 6% 0.4% higher concentrations index factor (CIF) 71% but concentrations. Flax enhance cracking while maintaining economic efficiency, offering viable solution stabilizing clays geotechnical applications.
