Abstract In the context of climate change and circular economy, biochar has recently found many applications in various sectors as a versatile recycled material. Here, we review application biochar-based for carbon sink, covering agronomy, animal farming, anaerobic digestion, composting, environmental remediation, construction, energy storage. The ultimate storage reservoirs are soils, civil infrastructure, landfills. Biochar-based fertilisers, which combine traditional fertilisers with nutrient carrier, promising agronomy. use feed additive animals shows benefits terms growth, gut microbiota, reduced enteric methane production, egg yield, endo-toxicant mitigation. Biochar enhances digestion operations, primarily biogas generation upgrading, performance sustainability, mitigation inhibitory impurities. composts, controls release greenhouse gases microbial activity. Co-composted improves soil properties crop productivity. Pristine engineered can also be employed water remediation to remove pollutants. added cement or asphalt, thus conferring structural functional advantages. Incorporating biocomposites insulation, electromagnetic radiation protection moisture control. Finally, synthesising materials requires additional functionalisation.

The contamination of soil with organic pollutants has been accelerated by agricultural and industrial development poses a major threat to global ecosystems human health. Various chemical physical techniques have developed remediate soils contaminated pollutants, but challenges related cost, efficacy, toxic byproducts often limit their sustainability. Fortunately, phytoremediation, achieved through the use plants associated microbiomes, shown great promise for tackling environmental pollution; this technology tested both in laboratory field. Plant-microbe interactions further promote efficacy plant growth-promoting bacteria (PGPB) used assist remediation pollutants. However, efficiency microbe-assisted phytoremediation can be impeded (i) high concentrations secondary toxins, (ii) absence suitable sink these (iii) nutrient limitations, (iv) lack continued release microbial inocula, (v) shelter or porous habitats planktonic organisms. In regard, biochar affords unparalleled positive attributes that make it bacterial carrier health enhancer. We propose several barriers overcome integrating plants, PGPB, soil. Here, we explore mechanisms which PGPB soils, thereby improve analyze cost-effectiveness, feasibility, life cycle, practicality integration sustainable restoration management

Engineered biochar for environmental decontamination in aquatic and soil systems: a review

Carbon Research, Год журнала: 2022, Номер 1(1)

Опубликована: Июнь 18, 2022

Abstract Contamination of aquatic and soil systems by organic inorganic pollutants has become a serious issue concern worldwide. Viable cost-effective solutions are urgently needed to mitigate the negative impacts diverse on environment human health. Biochar emerged as an effective green material for remediation wide spectrum (in)organic pollutants. However, applications pristine biochar in decontamination have encountered bottlenecks due its limited properties which cannot meet desired requirements. Therefore, multiple modification methods been developed tailoring physicochemical enhance effectiveness environmental decontamination. This work provides holistic review recent advances synthesis engineered using physical, chemical, biological methods. Further related mechanisms field also summarized discussed. In addition, existing challenges research gaps outlined, future needs proposed. summarizes scientific opportunities comprehensive understanding biochars materials contaminated water soil.

Adsorption of Pollutants from Wastewater by Biochar: A Review

Journal of Hazardous Materials Advances, Год журнала: 2022, Номер 9, С. 100226 - 100226

Опубликована: Дек. 23, 2022

Biochar is a functional material prepared under controlled thermal decomposition of organic feedstocks from crops, forestry residues, sewage sludge, algal biomass, and poultry manure. Due to its intrinsic properties, biochar has been widely used as an adsorbent remove vide range pollutants such pollutants, microplastics, heavy metals, nutrients water wastewater. Currently, the accumulation in industrial, municipal agricultural wastewater become major challenge focus. This study reviewed significant number articles focused on removing (fertilizer's, antibiotics, PAHs, PCBs). The significantly reduce crop yield, quality environment dangerous human health. percentage removal metals aqueous solution (88–98%) using adsorption isotherms found be higher than industrial (55–60%) (80–85%). effective contaminants samples field-scale enhanced by increasing specific surface area pore volume granules after post-treatment.
