A Workshop in The College of Engineering Explores Converting Waste Oil into Low-Cost Detergents
The College of Engineering at the University of Samarra organized a specialized training workshop titled “Converting Waste Oil into Effective Low-Cost Detergents.” The session was presented by Assoc. Prof. Dr. Zainab Abdul Majeed Khalaf (Department of Electromechanical Engineering) and Assist. Lect. Sahar Adnan Ahmed (College of Engineering, University of Tikrit).
The primary goal of the workshop was to demonstrate how to repurpose used oils—such as cooking oil—and transform them from environmental pollutants into high-value, economical cleaning products. By using simplified chemical processes, this initiative addresses the risks waste oils pose to soil, water resources, and sewage systems.
Dr. Zainab presented the theoretical foundation, focusing on the saponification process. This involves the chemical reaction between triglycerides and alkaline substances to produce soap and glycerin.
The technical walkthrough included, Scientific Equations: Analyzing exact mixing ratios and quality standards, Production Stages: Filtering waste oil, thermal control, and precise mixing Quality Assurance and Final testing phases to ensure proper texture and safe pH levels.
In the practical segment, Ms. Sahar conducted a live demonstration, converting oil into detergents in front of the participants to ensure a clear understanding of the manufacturing mechanism.
The workshop concluded by highlighting the strategic dimensions of oil recycling as a pillar of the Circular Economy.
The speakers emphasized its potential to Create job opportunities and low-cost home-based businesses, Protect water resources from contamination and Enhance community awareness by turning waste into sustainable economic products capable of competing with commercial alternatives.
