Multifunctional applications of biochar beyond carbon storage

International Materials Reviews, Journal Year: 2021, Volume and Issue: 67(2), P. 150 - 200

Published: May 7, 2021

Biochar is produced as a charred material with high surface area and abundant functional groups by pyrolysis, which refers to the process of thermochemical decomposition organic at elevated temperatures in absence oxygen. The carbon component biochar relatively stable, and, hence, was originally proposed soil amendment store soil. has multifunctional values that include use it for following purposes: improve health, nutrient microbial carrier, immobilising agent remediation toxic metals contaminants water, catalyst industrial applications, porous mitigating greenhouse gas emissions odorous compounds, feed supplement animal health intake efficiency thus, productivity. This article provides first time an overview unintended consequences applications.

A review of pyrolysis technologies and feedstock: A blending approach for plastic and biomass towards optimum biochar yield

Renewable and Sustainable Energy Reviews, Journal Year: 2022, Volume and Issue: 167, P. 112715 - 112715

Published: June 22, 2022

The efficient and sustainable disposal or value addition of waste plastic has major importance. Recent studies on the char produced via pyrolysis have demonstrated that it is a valuable additive with multiple applications ranging from soil water amendment, improving agricultural yield, supercapacitors, fuel cells, in support/catalysts, chemistry, carbon sequestration. Thus, essential to ensure quality efficacy biochar any combination feedstock process maximum benefits. However, very few focussed techniques parameters optimize yield. This study aims review techniques, reactor types, identify could enhance generation co-pyrolysis biomass feedstock. discusses production mechanism technology, types. followed by factors can be used production. Accordingly, identified temperature, heating rate, bed height type, residence time, pressure, type blending ratio as determinants had highest influence stability, content biochar.

Biochar applications influence soil physical and chemical properties, microbial diversity, and crop productivity: a meta-analysis

Biochar, Journal Year: 2022, Volume and Issue: 4(1)

Published: Feb. 16, 2022

Abstract Biochar is a widely known soil amendment. Here we synthesize the available information on influence of biochar application different properties and crop productivity using meta-analysis. Global data applications physical, chemical, microbial properties, were extracted from literature statistically analyzed. Based selection criteria, 59 studies published between 2012 2021 selected for Correlations developed effect size productivity. Application increased pH, cation exchange capacity, organic carbon by 46%, 20%, 27%, respectively, with greater effects in coarse fine-textured soils. Effects chemical variable among prepared feedstocks. Among physical reduced bulk densities 29% porosity 59%. at higher pyrolytic temperatures (> 500 ℃) improved density to extents (31% 66%, respectively). lower (< had diversity (both bacterial fungal), more diverse populations medium textured soils, while fungal fine only soil. The was correlated responses meta-analysis highlighted need conduct long-term field experiments provide better explanations changes as it undergoes aging, its longer-term timing re-application biochars.

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.

Biochar is gaining significant attention due to its potential for carbon (C) sequestration, improvement of soil health, fertility enhancement, and crop productivity quality. In this review, we discuss the most common available techniques biochar production, main physiochemical properties biochar, effects on including physical, chemical, biological parameters quality fertility, nutrient leaching, salt stress, addition, impacts addition salt-affected heavy metal contaminated soils were also reviewed. An ample body literature supports idea that amended with has a high increase concomitant in structure, use efficiency (NUE), aeration, porosity, water-holding capacity (WHC), among other amendments. However, increases biochar-amended are frequently reported coarse-textured sandy compared fine-textured fertile soils. effect microbial community composition abundance. The negative polluted have plant growth yield components such as aggregation stability can be ameliorated by application biochar. Moreover, positive been observed when was applied organic inorganic amendments fertilizers. decrease nitrogen (N) leaching volatilization well NUE. some biomass activity reported.
