Biomass-derived biochar in wastewater treatment- a circular economy approach

Waste Management Bulletin, Journal Year: 2023, Volume and Issue: 1(4), P. 1 - 14

Published: July 29, 2023

Over the years, promising results have been demonstrated using various biomass-based adsorbents for treatment of wastewater. However, circular economy prospect these has grossly neglected. This mini-review provides an inclusive overview applications biomass-derived biochar in wastewater within framework a economy. The application contaminants such as organic pollutants, heavy metals, nutrients, and leachates were highlighted. It further discusses adsorption capacity different types performance evaluation biochar-based systems. In addition, approach construction industry, refinery sector, sustainable agricultural practices discussed. What's more? machine learning study was briefly Furthermore, review examines environmental economic considerations associated with utilization toward achieving eco-friendliness sustainability. Finally, research gaps identified future development.

Biochar as a Soil Amendment for Restraining Greenhouse Gases Emission and Improving Soil Carbon Sink: Current Situation and Ways Forward

Sustainability, Journal Year: 2023, Volume and Issue: 15(2), P. 1206 - 1206

Published: Jan. 9, 2023

The global exponential rise in greenhouse gas (GHG) emissions over the last few decades has triggered an urgent need to contextualize low-cost and evergreen technologies for restraining GHG production enhancing soil carbon sink. GHGs can be mitigated via incorporating biochar into matrix sequestrate mineralized a stable form upon organic matter decomposition soil. However, efficiency of using offset from terrestrial ecosystems is still debatable. Moreover, literature, shows high functionality short-term laboratory studies, but it minimal or negative impacts field-scale experiments, leading conflicting results. This paper synthesizes information on ability mitigate dioxide (CO2), nitrous oxide (N2O), methane (CH4) biomass, with emphasis cropland soils. feedstock type, pyrolysis temperature, application rate factors showed significant effects controlling effectiveness emissions. Our study demonstrates that biochar, taken as whole, seen powerful easy-to-use tool halting rising tide Nonetheless, future research should focus (i) identifying other indirect related physicochemical characters (such pH/EH CaCO3 contents) may control (ii) fabricating aged biochars low nitrogen footprints, (iii) functionalizing biologically activated suppress CO2, CH4, N2O Overall, our paradoxical findings highlight functionalize modern capacity abate locking up their release carbonaceous lattice biochar.

Utilization of biochar for remediation of heavy metals in aqueous environments: A review and bibliometric analysis

Heliyon, Journal Year: 2024, Volume and Issue: 10(4), P. e25785 - e25785

Published: Feb. 1, 2024

Biochar usage for removing heavy metals from aqueous environments has emerged as a promising research area with significant environmental and economic benefits. Using the PICO approach, question aimed to explore using biochar remove media. We merged data Scopus Web of Science Core Collection databases acquire comprehensive perspective subject. The PRISMA guidelines were applied establish search parameters, identify appropriate articles, collect bibliographic information publications between 2010 2022. bibliometric analysis showed that biochar-based metal remediation is field increasing scholarly attention. removal Cr(VI), Pb(II), Cd(II), Cu(II) was most studied among metals. identified five main clusters centered on adsorption, water treatment, adsorption models, analytical techniques, hydrothermal carbonization by performing keyword co-occurrence analysis. Trending topics include reusability, modification, acid mine drainage (AMD), wastewater hydrochar. reutilization metal-loaded spent includes transforming it into electrodes supercapacitors or stable catalyst materials. This study provides overview in aquatic highlights knowledge gaps future directions.

Effect of MnO2-biochar composites on promoting humification during chicken manure composting

Biochar, Journal Year: 2024, Volume and Issue: 6(1)

Published: March 28, 2024

Abstract The present study aimed to accelerate the humification and investigate how MnO 2 modification of biochar (MBC) drives humus formation during composting with chicken manure. In this study, compared control group (CK), addition MBC caused an increase in concentration both humic acid (HA), a respective enhancement 29.1% 37.2%. addition, also improved stability compost products. Hetero two-dimensional correlation spectra further exhibited that could alter mechanism fractions composting. Random forest analysis showed Microbacterium , Bacteroides Kroppenstedtia Gracilibacillus Lentibacillus were significantly related ( P < 0.05). enhanced absolute abundance these five genera structural equation model confirmed be indirectly involved formation, through production aromatic compounds via secondary metabolism. Additionally, directly transform organic components into macromolecular structures. Therefore, might direct response acceleration These findings demonstrate potential value harmless disposal hazardous biowastes Highlights changed fractions. Key identified.
