Scholarcy highlights

  • Electrochemical wastewater and soil treatments are exciting set of technologies that has been well-studied over the recent years as one of the most-effective remediation techniques for the removal of hazardous pollutants from liquids effluents and soil
  • The main requirement of these technologies is electricity and their sustainability can be largely improved if they are powered by renewable energy sources
  • This green energy powering can help to apply these technologies in remote areas, such as rural communities in developing countries, where no electricity grid is available
  • This review presents a comprehensive discussion on fundamental concepts and applications of renewable energy driven electrochemical technologies for treating hazardous pollutants in wastewater and contaminated soils
  • The last section focused on the challenges expected for the near future, describing the most promising storage system and evaluating the scale-up, environmental and economic concerns of the technologies studied in this work
