Synergistic remediation of cadmium-contaminated soil by biochar-cement-plant system: performance and underlying mechanism

Hexavalent Chromium Immobilization in Soil by Sludge Biochar Tubules Under Fluctuating Groundwater: Performance, Mechanisms and Engineering Potential

Although biochar has been widely applied for chromium (Cr)-contaminated soil remediation, its direct mixing with soil is limited by poor recoverability and insufficient long-term stability, while the role of groundwater table fluctuation (GTF) is often overlooked. In this study, we developed a biochar tubule-based stra...

Bio-cementation boosts organic carbon sequestration in coastal saline soils via aggregation, humification, and chemoautotrophs enrichment.

Formation of soil aggregates is crucial for coastal saline soils, as it improves the physicochemical characteristics of soil, and significantly influences the stability of soil organic carbon (SOC) and soil ecological functions. Applying organic fertilizer is a common way to improve these soils, but its exclusive use o...

Synergistic remediation of oil-contaminated soil using sorghum and oil sludge-derived biochar

Oil sludge contamination poses a significant threat to agricultural soil health and productivity. While biochar is a promising soil amendment, the synergistic potential of combining oil sludge-derived biochar with plant systems for holistic remediation remains poorly quantified. In a 60-day greenhouse study using a ful...

An integrated bio-geotechnical approach for sustainable desertification control: Synergistic mechanisms of enzymatic mineralization and ecological restoration.

Sand and dust storms (SDS) are severe geo-environmental hazards that threaten ecosystem stability and land productivity in arid regions. Enzyme-induced carbonate precipitation (EICP) is highly effective for SDS control and exhibits better ecological compatibility. Nevertheless, the specific interaction between engineer...

From Salt‐Affected Marginal Land Resource to Remediation Agent: Halophyte‐Derived Biochar for Ameliorating Cd‐Contaminated Acidic Soil

Cadmium (Cd) contamination of acidic soils poses a significant threat to ecosystem stability and crop health. This study evaluated the potential of biochar derived from the halophyte Salicornia europaea (SBC), a salt‐tolerant plant that grows on saline‐alkali marginal land, to remediate Cd‐contaminated acidic...
