With the rapid growth yield of global sewage sludge, rational and effective treatment disposal methods are becoming increasingly needed. Biochar preparation is an attractive option for sludge treatment, excellent physical chemical properties derived biochar make it environmental improvement. Here, current application state was comprehensively reviewed, advances in mechanism capacity water contaminant removal, soil remediation, carbon emission reduction were described, with particular attention to key challenges involved, e.g., possible risks low efficiency. Several new strategies overcoming barriers realize highly efficient improvement highlighted, including modification, co-pyrolysis, feedstock selection pretreatment. The insights offered this review will facilitate further development biochar, towards addressing obstacles its crisis.

A review on magnetic biochar for the removal of heavy metals from contaminated soils: Preparation, application, and microbial response

Journal of Hazardous Materials Advances, Journal Year: 2023, Volume and Issue: 10, P. 100254 - 100254

Published: Feb. 11, 2023

Magnetic biochar has recently received much attention due to its magnetic separation capabilities. Additionally, makes an excellent soil amendment, making it increasingly appealing choice for the remediation of heavy metals in contaminated soils. However, explanation raw ingredients and procedures synthesizing lacks a complete analysis review biochar's influence factors, mechanism, microbial response remove from soil. Here, we provide detailed summary processing techniques needed make biochar. Generally, can be made same materials as with precursors. biochars produced several techniques, including ball milling, co-precipitation, hydrothermal carbonization, microwave pyrolysis, impregnation-pyrolysis. Then, factors influencing removal metal contamination by adsorption mechanism are described. The intrinsic properties metals, properties, feedstock, pyrolysis temperature, dosing amount significantly affected immobilization mechanisms include ion exchange, surface/co-precipitation, physical adsorption, complexation functional groups, π-π interactions, electrostatic attraction, oxidation-reduction. reaction physicochemical (pH, TOC/DOC/Biomass C, etc.) microorganisms addition were also highlighted. Finally, helpful recommendations future paths research offered, which had small positive impact on growth

Biochar-Based Strategies for Antibiotics Removal: Mechanisms, Factors, and Application

ACS ES&T Engineering, Journal Year: 2024, Volume and Issue: 4(6), P. 1256 - 1274

Published: April 22, 2024

The increasing use of antibiotics induces the spread antibiotic-resistant genes (ARGs) in environment, which seriously threatens natural ecosystem and human health. Reducing environment is utmost importance. Biochar, as a cost-effective, environmentally friendly, carbon-rich porous material with circular economy prospects, has shown great potential antibiotic remediation environment. adsorption mechanisms (e.g., electrostatic interaction, hydrogen bonding hydrophobic π–π electron donor–acceptor (EDA) pore diffusion) biotic roles biochar microbial shelter, carrier, mediator) synergistically promote removal from aqueous phase. This review critically discusses various based on classes antibiotics, efficacy removal, influence crucial parameters antibiotics. Furthermore, provides critical discussion engineering application biochar. Finally, highlights prospects challenges treating antibiotic-contaminated liquid streams.

Chitin and crawfish shell biochar composite decreased heavy metal bioavailability and shifted rhizosphere bacterial community in an arsenic/lead co-contaminated soil

Environment International, Journal Year: 2023, Volume and Issue: 176, P. 107989 - 107989

Published: May 24, 2023

Sustainable management of ever-increasing organic biowaste and arable soil contamination by potentially toxic elements are concern from both environmental agricultural perspectives. To tackle the waste issue crawfish shells simultaneously minimize threat arsenic (As) lead (Pb) to human health, a pot trial was conducted using chitin (CT), shell biochar (CSB), powder (CSP), CT-CSB composite compare their remediation efficiencies in As/Pb co-contaminated soil. Results demonstrated that addition all amendments decreased Pb bioavailability, with greatest effect observed for treatment. Application CSP CSB increased available As concentration, while significant decreases were CT treatments. Meanwhile, most effective enhancing enzyme activities including acid phosphatase, α-glucosidase, N-acetyl-β-glucosaminidase, cellobiohydrolase, whereas CSB-containing treatments suppressed enzymes. The altered bacterial abundance composition For instance, compared control, Chitinophagaceae 2.6-4.7%. relative Comamonadaceae 1.6% treatment, 2.1% increase noted Redundancy correlation analyses (at family level) indicated changes community structure linked bulk density, water content, availability soils. Partial least squares path modeling further chemical property (i.e., pH, dissolved carbon, cation exchange capacity) strongest predictor soils following amendment application. Overall, could be immobilizing restoring ecological functions contaminated
