There is an upsurge enthusiasm for utilizing biochar produced from waste-biomass in different fields, to address the most important ecological issues. This review focused on overview of remediating harmful contaminants biochar. Production various systems has been discussed. Biochar received consideration numerous analysts building up their proficiency remediate contaminants. Process parameters are fundamentally answerable deciding yield biomass. derived biomass exceptionally rich wellspring carbon thermal combustion. Activating another particular region growing utilization expelling specific contaminations. Closed-loop produce creates more opportunities. Decentralized production techniques serve as effective way providing employment opportunities, managing wastes, increasing resource circular bioeconomy. paper also covers knowledge gaps and perspectives field remediation toxic pollutants using

Review of organic and inorganic pollutants removal by biochar and biochar-based composites

Biochar, Год журнала: 2021, Номер 3(3), С. 255 - 281

Опубликована: Июль 7, 2021

Abstract Biochar (BC) has exhibited a great potential to remove water contaminants due its wide availability of raw materials, high surface area, developed pore structure, and low cost. However, the application BC for remediation many limitations. Driven by intense desire overcoming unfavorable factors, growing number researchers have carried out produce BC-based composite which not only improved physicochemical properties BC, but also obtained new material combined advantages other materials. This article reviewed previous researches on discussed in terms preparation methods, properties, performance contaminant removal, underlying adsorption mechanisms. Then recent research progress removal inorganic organic materials was systematically reviewed. Although shown or pollutants risks (such as stability biological toxicity) still need be noticed further study. At end this review, future prospects synthesis were proposed. review will help understand environmental remediation.

Multifunctional applications of biochar beyond carbon storage

International Materials Reviews, Год журнала: 2021, Номер 67(2), С. 150 - 200

Опубликована: Май 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.

Biochar Aging: Mechanisms, Physicochemical Changes, Assessment, And Implications for Field Applications

Environmental Science & Technology, Год журнала: 2020, Номер 54(23), С. 14797 - 14814

Опубликована: Ноя. 3, 2020

Biochar has triggered a black gold rush in environmental studies as carbon-rich material with well-developed porous structure and tunable functionality. While much attention been placed on its apparent ability to store carbon the ground, immobilize soil pollutants, improve fertility, temporally evolving situ performance these roles must not be overlooked. After field application, various factors, such temperature variations, precipitation events microbial activities, can lead fragmentation, dissolution, oxidation, thus causing drastic changes physicochemical properties. Direct monitoring of biochar-amended soils provide good evidence temporal evolution, but this requires long-term trials. Various artificial aging methods, chemical wet–dry cycling mineral modification, have therefore designed mimic natural mechanisms. Here we evaluate science biochar aging, critically summarize aging-induced properties, offer state-of-the-art for simulation approaches. In addition, implications are also considered regarding potential development deployment amendment. We suggest that improved prediction, methods shift from qualitative quantitative Furthermore, preaging may serve synthesize engineered biochars green sustainable applications.

Biochar and bacteria inoculated biochar enhanced Cd and Cu immobilization and enzymatic activity in a polluted soil

Environment International, Год журнала: 2020, Номер 137, С. 105576 - 105576

Опубликована: Фев. 18, 2020

The application of biochar in the remediation heavy metal contaminated soil has received increasing global attention during past decade. Although there been some review work on mechanism metals stabilization by biochar, effects and mechanisms interaction between functional microbes such as tolerant, adsorption transformation microbial strains remains unclear. In this paper, maize a metal-tolerant strain Pseudomonas sp. NT-2 were selected to investigate dynamic potential bacteria loaded Cd Cu mixed 75-day pot experiment. results showed that, compared single amendment, inoculated with at rate 5% significantly increased pH initial stage incubation, followed slight decline neutral-alkaline range reaction. addition could also increase proportion residual fraction Cu, thus reduce exchangeable carbonate bound species soil, which lead decreasing plant human bioavailability indicated DTPA simulated gastric solution extraction (UBM), respectively. Finally, bacterial markedly enhanced urease catalase activities later improved community end indicates recovery function after stabilization. research may provide new insights into development materials technologies for green sustainable combination microorganisms.

Biochar and Its Broad Impacts in Soil Quality and Fertility, Nutrient Leaching and Crop Productivity: A Review

Agronomy, Год журнала: 2021, Номер 11(5), С. 993 - 993

Опубликована: Май 17, 2021

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.
