Jeddah University develops a method to convert petroleum waste into antimicrobial ceramics
made Jeddah University a notable appearance at the Geneva International Exhibition of Inventions with a scientific innovation from the College of Science: an advanced method for preparing ceramic materials resistant to microbial activity.
The project, presented by Professor Dr. Amna Ali Siddiq, aims to address two environmental and industrial challenges simultaneously: the safe disposal of petroleum waste and the reduction of microbial growth on ceramic surfaces in various facilities. This transforms environmental challenges into promising industrial opportunities that support global sustainability goals.
Integration of biological properties
Dr. Yousef Mohamed El-Gamal revealed that the innovation's distinction lies in developing a scientific mechanism to combine petroleum waste sludge with local bauxite ore to produce a new class of ceramics with antimicrobial properties structurally integrated within the material itself.
This technology gives the product a qualitative advantage over traditional ceramics, as the resistance becomes an inherent part of the material's composition and not merely an external coating, thus ensuring long-lasting effectiveness in inhibiting bacterial and fungal growth.
Amazing research results
Dr. Afraa Mohammed Baghdadi confirmed that the research team has developed an optimal formula, designated RCB3, consisting of 60% bauxite ore and 40% petroleum waste.
Advanced analyses have demonstrated this formula's ability to produce highly efficient ceramic phases and refractory stones capable of withstanding temperatures exceeding 1500 degrees Celsius.
These findings open up broad prospects for utilizing this innovation in heavy industrial applications and producing high-quality, durable building and construction materials.
Local and international crowning
This scientific achievement culminated in obtaining a Saudi patent for 2024, in addition to winning prestigious awards, including being selected as one of the top 100 entrepreneurial projects by the Ministry of Education and receiving the Jeddah University Innovation Award.
This innovation embodies a practical model for the Kingdom's vision of transforming waste into high-value-added products, achieving tangible environmental and economic returns that enhance the standing of Saudi innovation in major international forums such as the Geneva Exhibition.
