Chromium exists from both natural geological processes and human actions, it has a substantial impact on health ecosystems. This study addresses the major challenges in using biochar as an environmentally friendly, sustainable, economical sorbent for removing chromium hexavalent throughout remediation process. The results exhibited that produced non-woody feedstocks pyrolyzed at (300°C −700°C) significantly large amount of various functional groups, higher pH (7 to 11.10) CEC (27 21.70 cmol kg−1), greater surface area (2–300 m2g−1), O/C H/C ratios with increasing carbonization temperature, adsorption capacities (1.63 435 mg g) superior performance removal compared biochars woody-biomass. use equilibrium isotherm, thermodynamic, kinetic models aids comprehending interactions between biochar, well their processes.

The accumulation of organic dyes and heavy metals (HMs) in sewage sludge (SS) after wastewater treatment is a significant problem due to the non-degradable nature these pollutants. Moreover, simultaneous removal HMs complex process SS treatment, such as anaerobic digestion (AD), has become attractive. present can have detrimental effect on digesters. These pollutants not only inhibit production methane, which crucial for biogas generation, but also affect stability AD result failure or inadequate performance process. This review highlights novel method removing from through use biochar modified with polyvinyl alcohol (PVA) chitosan (CTS). applications conventional been limited poor adsorption capacity. However, modification using PVA/CTS composites enhances properties surface functional groups, capacity, porosity, area selectivity, stability. Furthermore, this version function an additive boost production, viable source heat generation electricity supply. In addition, digestates be further processed plasma pyrolysis bound biochar. Plasma generates two major products: syngas slag. produced then used hydrogen, heat, electricity, while slag potentially reused biofertilizer agricultural sector. Additionally, study addresses challenges associated integration modifications, offers outlook understanding interactions between properties, microbial dynamics, presence micropollutants ensure economic viability scalability technology. comprehensive provides insights into potential PVA/CTS-modified effective systems, offering sustainable approach valuable resource recovery.

Microplastics (MPs) are prevalent emerging pollutants in soil environments, acting as carriers for other contaminants and facilitating combined pollution along with toxic metals like cadmium (Cd). This interaction increases effects poses substantial threats to ecosystems human health. The objective of this study was investigate the hydrodynamic adsorption Cd by conducting experiments where polystyrene microplastics (PS) biochar (BC) coexisted across various particle sizes (10 µm, 20 30 µm). Then, incubation were set up under conditions pollution, involving concentrations (0.5 g·kg

This study introduces an innovative approach to fabricate aluminum matrix composites strengthened with biochar, derived from renewable biomass sources. A systematic investigation of varying biochar weight percentages (0, 2.5, 5, 7.5, and 10 wt%) reveals substantial improvements in mechanical properties corrosion resistance. Mechanical assessments, including compressive strength hardness, demonstrate a significant enhancement incorporation. In this study, it was discovered that the composite 7.5 wt% exhibits optimal balance, displaying 8.83% increase 15.15% rise hardness compared base matrix. The further evaluates behavior through electrochemical analyses immersion tests 3.5% NaCl corrosive environments, highlighting superior resistance biochar-reinforced composites. Corrosion rates decrease by 73% for 24 h time, affirming its protective barrier against agents. research provides quantitative insights into tailoring reinforcement, offering promising avenue sustainable material development. resulting materials exhibit not only but also reduction rates, valuable uses industries need strong, eco-friendly solutions.
