Biochar-microorganism interactions for organic pollutant remediation: Challenges and perspectives

Environmental Pollution, Год журнала: 2022, Номер 308, С. 119609 - 119609

Опубликована: Июнь 11, 2022

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.

Nanomaterials for the Treatment of Heavy Metal Contaminated Water

Polymers, Год журнала: 2022, Номер 14(3), С. 583 - 583

Опубликована: Янв. 31, 2022

Nanotechnology finds its application almost in every field of science and technology. At the same time, it also helps to find solution various environment-related problems, especially water contamination. Nanomaterials have many advantages over conventional materials, such as high surface area, both polar non-polar chemistries, controlled size-tunable, easier biodegradation, which made them ideal candidates for environmental remediation well. Herein, applications non-carbon nanomaterials, layered double hydroxides, iron oxide magnetite nanoparticles, nano-polymer composites, metal nanomaterials nanomembranes/fibers heavy contaminated are reviewed. These due their tunable unique chemistry small size greater potentials applications.

Surface Modification of Biochar for Dye Removal from Wastewater

Catalysts, Год журнала: 2022, Номер 12(8), С. 817 - 817

Опубликована: Июль 26, 2022

Nowadays, biochar is being studied to a great degree because of its potential for carbon sequestration, soil improvement, climate change mitigation, catalysis, wastewater treatment, energy storage, and waste management. The present review emphasizes on the utilization biochar-based nanocomposites play key role in decontaminating dyes from wastewater. Numerous trials are underway synthesize functionalized, surface engineered that can sufficiently remove dye-contaminated removal via natural modified follows numerous mechanisms such as precipitation, complexation, ion exchange, cation–π interactions, electrostatic attraction. Further, production modification promote good adsorption capacity dye owing properties tailored stage linked with specific hydrophobic interactions. Meanwhile, framework artificial neural networking machine learning model efficiency proposed even though studies still their infancy stage. article recommends smart technologies modelling forecasting should be included proper applications.

Application of biochar in concrete – A review

Cement and Concrete Composites, Год журнала: 2023, Номер 143, С. 105204 - 105204

The continuous rise in global temperatures is an evidence of climate change. CO2 emissions have caused major problems owing to its contribution In particular, the construction industry has a considerable carbon footprint. Therefore, investigations into change mitigation are indeed priority. All steps process, from raw materials preparation cement production, contribute emissions. This can be mitigated certain extent by incorporating bio-based constituents materials. However, may negatively affect reaction and structural performance, despite their positive environmental impacts. Biochar, carbon-rich product biomass pyrolysis, considered potential substitute for replacement that enhance properties if used appropriate amounts. Although biochar conventionally been as soil amendment agricultural industry, researchers recently investigated applicability concrete. Importantly, results thus far reported enhancement mechanical, thermal, physical cement. review provides comprehensive overview physicochemical added cementitious materials, including fresh hardened biochar-cement mixtures considering both economic aspects.
