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

Environmental Chemistry Letters, Journal Year: 2022, Volume and Issue: 20(4), P. 2385 - 2485

Published: May 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.

New trends in biochar pyrolysis and modification strategies: feedstock, pyrolysis conditions, sustainability concerns and implications for soil amendment

Soil Use and Management, Journal Year: 2020, Volume and Issue: 36(3), P. 358 - 386

Published: April 11, 2020

Abstract As a waste‐derived soil amendment with long history, biochar has received extensive attention for its capability to improve fertility/health; remove or immobilize contaminants in soil, water and air; mitigate climate change. With the aim of producing engineered biochars excellent performances, new trends pyrolytic production modification strategies have emerged. This review critically summarizes novel pyrolysis methods (e.g., microwave‐assisted pyrolysis, co‐pyrolysis wet pyrolysis) approaches mineral modification, photocatalytic electrochemical modification) focus on (a) mechanisms involved environmental remediation processes including immobilization, contaminant adsorption catalytic oxidation; (b) effects feedstock conditions physicochemical properties; (c) sustainability considerations strategies; (d) feasibility extrapolating results from wastewater treatment remediation. It is argued that order achieve maximum net benefits, ‘greener’ are warranted, risks associated contaminated sorption can be minimized through various co‐pyrolysis). Furthermore, combined emerging synthesize more ‘effective’ biochars. Considering similar aims increase surface area, introduce oxygen‐containing functional groups, aromaticity), applicability several could future expanded adsorption/degradation aqueous media remediation/fertility improvement.

Biochar-based slow-release of fertilizers for sustainable agriculture: A mini review

Environmental Science and Ecotechnology, Journal Year: 2022, Volume and Issue: 10, P. 100167 - 100167

Published: March 5, 2022

Increasing global population and decreasing arable land pose tremendous pressures to agricultural production. The application of conventional chemical fertilizers improves production, but causes serious environmental problems significant economic burdens. Biochar gains increasing interest as a soil amendment. Recently, more attentions have been paid biochar-based slow-release (SRFs) due the unique properties biochar. This review summarizes recent advances in development, synthesis, application, tentative mechanism SRFs. development mainly undergoes three stages: (i) amendment using biochar, (ii) interactions between nutrients (iii) Various methods are proposed improve fertilizer efficiency majorly including in-situ pyrolysis, co-pyrolysis, impregnation, encapsulation, granulation. Considering distinct features different methods, integrated promising for fabricating effective in-depth understanding nutrient loading slow release is discussed based on current knowledge. Additionally, perspectives challenges potential SRFs described. Knowledge surveyed from this indicates that applying viable way promoting sustainable agriculture.
