Pune: Defence Institute of Advanced Technology Pune – DIAT researchers have developed an innovative algae-based technology that removes oil pollutants from contaminated water bodies, offering an environmentally friendly alternative to conventional oil spill cleanup methods.
The research, led by Prof. Balasubramanian K. from the Department of Metallurgical and Materials Engineering, explores the use of naturally occurring microalgae to address the growing challenge of oil pollution in aquatic ecosystems.
With increasing incidents of oil spills resulting from industrial accidents, transportation mishaps, and recent global conflicts affecting energy infrastructure, protecting rivers, lakes, and marine ecosystems has emerged as a significant environmental priority.
Against this backdrop, DIAT researchers have focused on developing sustainable and eco-friendly technologies capable of cleaning oil-contaminated water without causing further environmental damage.
The research demonstrates that microalgae possess the natural ability to capture, absorb, and gradually break down petroleum-based pollutants while simultaneously supporting healthier aquatic ecosystems.
In laboratory studies conducted by DIAT researchers, Spirulina (blue-green algae) removed nearly 90% of heavy hydraulic oil within just 24 hours, showcasing its remarkable oil adsorption capability.
The findings have been published in a leading Elsevier journal, and the research team is now extending the technology to evaluate its effectiveness in removing diesel and petrol contaminants.
The innovation has also been protected through a patent filing. The project further expands upon the HP Innovation Green Award recently received by Prof. Balasubramanian K.
Unlike conventional oil spill cleanup techniques that often depend on chemicals or energy-intensive processes, the solution developed by DIAT researchers offers a sustainable and environmentally compatible alternative.
Building on the laboratory results, the team is developing biodegradable biohybrid materials using advanced 3D printing technology.
These materials are intended to create floating remediation platforms, porous filtration systems, and water purification solutions for rivers, lakes, and coastal waters.
The nature-inspired technology has the potential to significantly strengthen environmental protection, sustainable water management, and future oil spill response capabilities.
According to the research team, the innovation could contribute to cleaner aquatic ecosystems while addressing both national and global environmental challenges.
The work also reflects the continued commitment of DIAT researchers to developing advanced technologies that combine scientific innovation with environmental sustainability, reinforcing the Defence Institute of Advanced Technology’s role in addressing pressing ecological issues through research and innovation.
