Biochar Production, Soil Remediation, and Heavy Metal Removal
This community investigates the production of biochar from agricultural waste and its application to remove heavy metals from soil and water, as well as to enhance soil fertility and carbon storage.
The work centers on converting biomass feedstocks like rice husk, straw, and sewage sludge into biochar through pyrolysis and hydrothermal carbonization. Researchers focus on modifying this material to improve its ability to adsorb cadmium, lead, and other heavy metals from contaminated soil and aqueous solutions. A significant portion of the literature examines how biochar amendments affect soil microbial communities, nitrogen and phosphorus dynamics, and long-term carbon sequestration. The field also addresses the regeneration of biochar adsorbents for sustainable wastewater treatment and the optimization of production parameters to maximize yield and functionality.
The largest share of the community's output is found in carbon research, accounting for 0.3% of all carbon research, and 2,564 papers here. Nitrogen research also represents a significant portion, with 0.3% of all nitrogen research and 1,948 papers. Phosphorus research contributes 0.4% of its total field, comprising 1,374 papers.
The community comprises 11,118 papers, primarily published in Fuel, Bioresource Technology, and The Science of The Total Environment. Recent work continues to focus on tailoring biochar for specific rhizosphere engineering, heavy metal immobilization, and the catalytic degradation of pollutants in wastewater.
