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.

Numerous harmful chemicals are introduced every year in the environment through anthropogenic and geological activities raising global concerns of their ecotoxicological effects decontamination strategies. Biochar technology has been recognized as an important pillar for recycling biomass, contributing to carbon capture bioenergy industries, remediation contaminated soil, sediments water. This paper aims critically review application potential biochar with a special focus on synergistic antagonistic contaminant-degrading microorganisms single mixed-contaminated systems. Owing high specific surface area, porous structure, compatible chemistry, can support proliferation activity microorganisms. A combination remove variety contaminants gained popularity recent years alongside traditional chemical physical technologies. The microbial compatibility be improved by optimizing parameters so that toxic pollutant release is minimized, biofilm formation encouraged, populations enhanced. Biocompatible thus shows bioremediation organic harboring populations, releasing enzymes, protecting beneficial from immediate toxicity surrounding contaminants. recommends biochar-microorganism co-deployment holds great removal thereby reducing risk human environmental health.
