Innovative Eco-Friendly Coating Reduces Fatberg Formation by 80%
Published on: November 14, 2024
Revolutionizing Sewer Systems
Engineers from RMIT University have developed a protective coating for concrete pipes that could drastically reduce the formation of “fatbergs” in sewer systems.
The Fatberg Problem
The accumulation of fats, oils, and grease (FOG) is notorious for solidifying in concrete pipes and sewers, causing approximately 50% of sewer blockages in the United States and 40% in Australia. Maintenance and rehabilitation costs due to these blockages reach $25 billion in the U.S. and $100 million in Australia annually.
A Sustainable Solution
The polyurethane coating enriched with zinc developed by the team offers a sustainable solution by reducing calcium release from concrete by 80% compared to uncoated concrete. This significant reduction helps prevent the formation of fatbergs.
Research Findings
Led by Dr. Biplob Pramanik, the study simulated a sewer environment under extreme conditions to accelerate fatberg formation over 30 days. The research revealed a 30% reduction in FOG accumulation on the coated concrete compared to uncoated surfaces.
Innovative Features
This innovative coating remains stable in water and withstands temperatures up to 850 degrees Celsius. It is self-repairing at room temperature, allowing it to heal minor damages, thus extending its lifespan. Inspired by nature’s regenerative capabilities, the coating mimics the healing process of human skin.
Future Developments
The RMIT team is working on an enhanced coating to further reduce FOG deposition in sewers while increasing its self-repairing capabilities and mechanical strength. Additionally, Dr. Pramanik leads a project in collaboration with the ARC Linkage Project to develop an advanced grease interceptor that outperforms current technologies in removing small FOG particles from restaurants and food service establishments.
Conclusion
The invention from RMIT represents a significant advancement in the sustainability of sewer systems. By reducing FOG accumulation, it minimizes blockages and the need for cleaning and repair, thereby conserving resources and reducing the carbon footprint associated with maintaining these systems.
This technology not only contributes to a more efficient and cost-effective urban infrastructure but also offers a viable and eco-friendly solution that could be implemented globally to enhance urban quality of life and promote sustainable sanitation practices.
