Special Issue Information

Dear Colleagues,

This Special Issue is dedicated to exploring the potential of Microbially Induced Carbonate Precipitation (MICP) in non-conventional waters, such as wastewater, brine, contaminated waters, and seawater. MICP has proven to be a promising technology within the framework of the circular economy, as it not only facilitates mineral formation but also offers innovative solutions for environmental remediation and sustainable energy production.

This Special Issue invites contributions that address the latest advancements in MICP, including, but not limited to, the following:

  • Mechanisms and pathways of MICP in various non-conventional water sources.
  • Applications of MICP in mineral recovery and value-added product formation.
  • Strategies for using MICP in environmental remediation efforts.
  • Applications demonstrating the successful implementation of MICP in sustainable energy production.
  • Integrating MICP into circular economy frameworks for enhanced resource management.

We aim to provide a comprehensive overview of state-of-the-art research and practical applications of MICP in non-conventional waters, fostering collaboration between academia and industry to advance sustainable practices and technologies.

The growing scarcity of freshwater has accelerated the global deployment of desalination technologies, especially reverse osmosis (RO), as an alternative to meet increasing water demands. However, this process generates substantial quantities of brine—a hypersaline waste stream that can severely impact marine ecosystems if improperly managed. This perspective review explores the use of urease-driven Microbially Induced Carbonate Precipitation (MICP) as a biotechnological solution aligned with circular economy principles for the treatment and valorization of RO brines. Through the enzymatic activity of ureolytic microorganisms, MICP promotes the precipitation of calcium carbonate and other mineral phases, enabling the recovery of valuable elements and reducing environmental burdens. Beyond mineral capture, MICP shows promise in the stabilization of toxic metals and potential integration with microbial electrochemical systems for energy applications. This review summarizes current developments, identifies existing challenges, such as microbial performance in saline conditions and reliance on conventional urea sources, and proposes future directions focused on strain optimization, nutrient recycling, and process scalability for sustainable implementation.
