Special Issue Information

Dear Colleagues,

Heavy metals are important contaminants in water and soil systems. Although there are many technologies treating heavy metals in water and soil, conventional technologies consume substantial energy and/or chemicals. To deal with climate change according to the Paris Agreement, energy-efficient technologies with low carbon footprint should be developed and shared. Moreover, quicklime and hydrated lime are often used to treat heavy metals, but they generate a large amount of carbon dioxide during their production. Furthermore, to treat contaminants during sustainable development, cost-effective technologies are needed particularly in developing countries.

The aim of this Special Issue is therefore to encourage the sharing of research about energy- and cost-efficient technologies to treat heavy metals in water or soil.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Energy-efficient treatment of water and soil;
  • Alternative treatment chemicals to reduce carbon footprint;
  • Passive treatment of dissolved heavy metals;
  • Soil stabilization by cost-efficient materials;
  • Sorption of heavy metals.

I look forward to receiving your contributions.

Guest Editor

Coal-mining activities have well-documented adverse effects on both the environment and human health. Acid mine drainage, a pivotal concern, necessitates effective interventions. This study introduces a novel solution: a modified constructed wetlands crafted exclusively from waste materials, ensuring cost-effectiveness. The innovation yielded exceptional results, achieving a noteworthy reduction of up to 99% in heavy metal concentrations, alongside swift pH normalization. What sets this study apart is its potential beyond the laboratory setting; the utilization of waste materials and low-cost methodologies underscores its scalability and practicality. This solution addresses immediate challenges and showcases promise for real-world implementation. Moreover, the results of the study extend to its insights, which offer a comprehensive examination of the method’s reusability prospects, illuminating its sustained impacts; the recommendations for future action enhance its practical significance. This study marks a significant advancement in tackling acid mine drainage. The modified constructed wetlands, driven by cost-effective waste materials, embody scalable and sustainable potential. With its holistic outlook and strategic roadmap, this study holds the key to transforming acid mine drainage challenges, particularly in rural and developing regions. Full article
