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.

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

Environmental Science & Technology, Journal Year: 2020, Volume and Issue: 54(23), P. 14797 - 14814

Published: Nov. 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.

Soil salinity: A global threat to sustainable development

Soil Use and Management, Journal Year: 2021, Volume and Issue: 38(1), P. 39 - 67

Published: Oct. 23, 2021

Abstract Soil is a vital resource for feeding the burgeoning global population, and it also essential realizing most of ‘United Nations Sustainable Development Goals (SDGs)’. For example, to ‘Zero hunger (SDG2), Good health well‐being (SDG3), Clean water sanitation (SDG6), Life on land (SDG15)’. Excess salts present in soil make saline, poses significant threat agricultural production environmental health. salinity an extensive problem spreads over one billion hectares extended 100 countries. This paper presents comprehensive review management through applications remote sensing GIS. All possible sources relevant current literature were accessed more than 260 publications collected carefully analysed, this review.
