Orenji2Help is a sustainable research initiative designed to tackle the dual issues of classroom maintenance and organic waste management at MRSM. Standard whiteboards often suffer from "ghosting," which commercial cleaners—laden with synthetic chemicals—fail to remove effectively. Meanwhile, citrus waste from the college dining hall is typically discarded, leading to the production of methane gas in landfills. This project utilizes a cold maceration process to extract D-Limonene, a natural hydrocarbon solvent, from orange peels using a 70% Isopropyl Alcohol carrier. The resulting bio-solvent operates on the "like-dissolves-like" principle, successfully breaking down non-polar ink resins and even permanent markers. By upcycling local waste into a high-performance, non-toxic, and cost-effective cleaning agent, Orenji2Help demonstrates a practical application of Green Chemistry and the Circular Economy, proving that environmental responsibility can drive functional innovation.
