Biochar for the removal of contaminants from soil and water: a review

Biochar, Год журнала: 2022, Номер 4(1)

Опубликована: Март 15, 2022

Abstract Biochar shows significant potential to serve as a globally applicable material remediate water and soil owing the extensive availability of feedstocks conducive physio-chemical surface characteristics. This review aims highlight biochar production technologies, characteristics biochar, latest advancements in immobilizing eliminating heavy metal ions organic pollutants water. Pyrolysis temperature, heat transfer rate, residence time, type feedstock are critical influential parameters. Biochar’s efficacy managing contaminants relies on pore size distribution, groups, ion-exchange capacity. The molecular composition physical architecture may be crucial when practically applied soil. In general, produced at relatively high pyrolysis temperatures can effectively manage via increasing area, hydrophobicity microporosity. generated lower is deemed more suitable for removing polar inorganic through oxygen-containing functional precipitation electrostatic attraction. also presents existing obstacles future research direction related biochar-based materials effluents Graphical

Biochar for agronomy, animal farming, anaerobic digestion, composting, water treatment, soil remediation, construction, energy storage, and carbon sequestration: a review

Environmental Chemistry Letters, Год журнала: 2022, Номер 20(4), С. 2385 - 2485

Опубликована: Май 7, 2022

Abstract In the context of climate change and circular economy, biochar has recently found many applications in various sectors as a versatile recycled material. Here, we review application biochar-based for carbon sink, covering agronomy, animal farming, anaerobic digestion, composting, environmental remediation, construction, energy storage. The ultimate storage reservoirs are soils, civil infrastructure, landfills. Biochar-based fertilisers, which combine traditional fertilisers with nutrient carrier, promising agronomy. use feed additive animals shows benefits terms growth, gut microbiota, reduced enteric methane production, egg yield, endo-toxicant mitigation. Biochar enhances digestion operations, primarily biogas generation upgrading, performance sustainability, mitigation inhibitory impurities. composts, controls release greenhouse gases microbial activity. Co-composted improves soil properties crop productivity. Pristine engineered can also be employed water remediation to remove pollutants. added cement or asphalt, thus conferring structural functional advantages. Incorporating biocomposites insulation, electromagnetic radiation protection moisture control. Finally, synthesising materials requires additional functionalisation.
