Special Issue Information

Dear Colleagues,

The interfacial processes of contaminants in soil–groundwater systems are of critical importance for environmental sustainability, serving as a key safeguard for mitigating negative environmental impacts and maintaining soil ecosystem health and water security. Understanding the transport and transformation mechanisms of contaminants, along with sustainable remediation technologies, is essential for achieving regional and even global sustainable development goals.

This Special Issue seeks innovative research on contaminant behavior at soil–water interfaces, eco-friendly remediation technologies, and policy frameworks for sustainable groundwater management. We welcome high-quality studies integrating experimental, modeling, and field approaches to advance science-driven solutions.

Topics of interest include, but are not limited to,

  • Contaminant transport and fate in porous media;
  • Biogeochemical interactions at interfaces;
  • Sustainable remediation strategies (e.g., phytoremediation, biochar);
  • Microbial-driven contaminant degradation;
  • Socio-economic and policy aspects of groundwater remediation.

We invite submissions that bridge fundamental research with practical applications, fostering sustainable solutions for contaminated environments.

This study examined the effectiveness of using biochar from the tanning industry as a silicon carrier to reduce trace element toxicity and improve plant nutrition in soil–plant systems. Silicon-enriched biochar was produced from chromium-free leather waste and applied in 21-day pot trials with cucumber. It contained 11.6 ± 2.3% SiO2 and effectively served as a slow-release silicon carrier. Optimal plant growth and nutrient uptake were achieved with the application of 100% silicon without additional NPK fertilizers, demonstrating a strong positive correlation with essential trace elements such as copper and iron. Importantly, silicon fertilization significantly reduced the uptake of toxic metals such as Al, Cd, and Ti, underscoring the potential of silicon-enriched biochar for phytoremediation and sustainable crop production. Using silicon-enriched biochar from industrial leather waste thus provides a novel, sustainable strategy to improve soil fertility and plant health while repurposing waste. Future work should include long-term field trials and examine species-specific responses and management practices to scale up this approach for enhanced crop resilience. Full article
