The effective treatment of antibiotic wastewater is necessary to the cleaner production of many industries. Herein, a novel catalyst of biochar-supported nano zero-valent iron-copper (nZVI/Cu@BC) was synthesized, which showed more efficient activation of peroxydisulfate (PDS) for sulfamethazine (SMZ) degradation than the catalyst before nZVC doping, from 77.81% to 96.44%. And it was found to be […]

Mixed pollution of nitrate, tetracycline (TC) and cadmium (Cd2+) induced by improper discharge of various wastewater from industry and agriculture has attracted extensive attention. A novel biocarrier (MBF@FMJSB) assembled with modified basalt fiber and modified wild jujube seed biochar (FMJSB) was used to construct fixed-biofilm reactor (FBR) for concurrent removal of nitrate, TC, and Cd2+. […]

Immobilization/stabilization is a common technique for remediating As and Cd-contaminated soil. However, the effectiveness of employed stabilizer plays a crucial role in determining the fate of these contaminants. This study investigated the effectiveness and durability of a magnetic biochar-supported Ca-Mg-Al layered double hydroxide composite (FLBC) and its components in simultaneous remediation of As and Cd […]

The efficient removal of nitrate nitrogen (NO3–N) and reduction of greenhouse gas (GHG) emissions in bioretention system (BRS) poses challenges. This study aimed to investigate the performance of a pyrite/biochar-based BRS coupled with microbial fuel cell (MFC) (PBM-BRS) in terms of pollution removal, bioelectricity generation, and GHG emissions under various operating conditions. Compared with the […]

Waste biochar from biomass power generation and sintering dust from ferrous metallurgy were skillfully used to produce direct reduced iron (DRI) and syngas via a synergetic conversion in this study. The thermodynamic analysis of their related reactions, biochar conversion and reduction behavior of sintering dust were investigated. The biochar gasification and reduction of sintering dust […]

Carbon dioxide (CO2) emissions from the combustion of fossil fuels are contributing to global climate change and ocean acidification, and the development of low-cost, highly efficient CO2 capture adsorbents for the reduction of CO2 concentrations is now a matter of urgency. Herein, we developed amine-modified biochar-silica hybrid aerogels template cellulose nanocrystals (CNCs) for CO2 capture. […]

Antimony (Sb) and arsenic (As) pollution in the water environment pose a threat to the ecological environment and human health. A lot of studies have been conducted on the removal of pollutants from water by modified biochar, but little attention has been paid to the simultaneous removal of Sb and As from water. This study […]

Adding conductive materials for enhancing methane production from biomass has caused widespread attention. However, the discharge of digestive residues inevitably causes the loss of conductive materials, which not only weakens the roles of conductive materials but also increases the operating cost. This study aims to reveal the potentials of recycled magnetic biochar (MBC) in sludge […]

Innovative agricultural practices represent the future of the world in the sustainable improvement of agricultural productivity. Sustainable farming practices have been recognized and accepted by agricultural development stakeholders, to provide a wide range of social, economic, financial, and environmental benefits. Despite this recognition, the application of these practices in the literature has focused on socio-economic […]
