Environmental Science & Technology, Journal Year: 2018, Volume and Issue: 52(9), P. 5027 - 5047

Published: April 10, 2018

Biochar is the carbon-rich product of pyrolysis biomass under oxygen-limited conditions, and it has received increasing attention due to its multiple functions in fields climate change mitigation, sustainable agriculture, environmental control, novel materials. To design a "smart" biochar for environmentally applications, one must understand recent advances molecular structures explore potential applications generalize upon structure–application relationships. In this review, multilevel biochars are interpreted based on their elemental compositions, phase components, surface properties, structures. Applications such as carbon fixators, fertilizers, sorbents, carbon-based materials highlighted well structure-application Further studies suggested more detailed structural analysis separation combination macroscopic microscopic information develop higher-level selective applications.

Biochar production and use are part of the modern agenda to recycle wastes, retain nutrients, pollutants, heavy metals in soil offset some greenhouse gas emissions. Biochars from wood (eucalyptus sawdust, pine bark), sugarcane bagasse, substances rich nutrients (coffee husk, chicken manure) produced at 350, 450 750°C were characterized identify agronomic environmental benefits, which may enhance quality. derived have greater potential for improving C storage tropical soils due a higher aromatic character, high concentration, low H/C ratio, FTIR spectra features as compared nutrient-rich biochars. The ash content associated with alkaline chemical species such KHCO3 CaCO3, verified by XRD analysis, made manure coffee husk biochars liming agents remediating acidic soils. High Ca K contents biomass can significantly replace conventional sources (mostly imported Brazil) Ca, suggesting value these High-ash biochars, low-temperatures (350 450°C) exhibited CEC values, be considered applicable material increase nutrient retention soil. Therefore, this study is predominantly regulated richness biomass, but an pyrolysis temperature strongly decrease adsorptive capacities A diagram benefits presented, along guidelines relate biochar properties uses. Based on properties, research needs identified directions future trials delineated.

Effects of biochar application on soil greenhouse gas fluxes: a meta-analysis

GCB Bioenergy, Journal Year: 2016, Volume and Issue: 9(4), P. 743 - 755

Published: June 2, 2016

Abstract Biochar application to soils may increase carbon (C) sequestration due the inputs of recalcitrant organic C. However, effects biochar on soil greenhouse gas ( GHG ) fluxes appear variable among many case studies; therefore, efficacy as a agent for climate change mitigation remains uncertain. We performed meta‐analysis 91 published papers with 552 paired comparisons obtain central tendency three main (i.e., CO 2 , CH 4 and N O) in response application. Our results showed that significantly increased by 22.14%, but decreased O 30.92% did not affect fluxes. As consequence, contribute an global warming potential GWP total large stimulation were suppressed when was added fertilized soils, indicating is unlikely stimulate agriculture sector, which fertilizer are common. Responses mainly varied feedstock source texture pyrolysis temperature biochar. Soil pH applied rate, latitude also influence fluxes, more limited extent. findings provide scientific basis developing rational strategies toward widespread adoption amendment mitigation.
