Mary Joy Bautista

Mary Joy Bautista is a researcher specialising in sustainable manufacturing and materials analysis within the metals and machining sector. With experience in evaluating cutting fluids, lubrication systems, and machining performance, she has also led pioneering work on elemental fingerprinting and quality assessment of steel rebar to ensure compliance with national standards and preventing substandard materials through a rapid on-site elemental analysis. This combined expertise in metal processing, material integrity, and industrial sustainability equips Mary Joy Bautista to design practical, science-based solutions. Driven by a commitment to greener manufacturing, she develops technologies that reduce environmental impact and enhance industrial reliability.

Her innovation introduces machining fluids derived from coconut oil as a direct replacement for mineral oil–based cutting fluids. Conventional machining fluids are often toxic, difficult to dispose of, and harmful to the environment. Coconut oil, by contrast, provides excellent lubrication, cooling properties, and natural stability without exposing workers to hazardous chemicals. The innovation includes both straight oil and water-soluble formulations suitable for metalworking industries. By using a renewable and biodegradable resource, this coconut oil–based machining fluid reduces dependence on imported petroleum products, cuts carbon emissions, and supports a more sustainable and environmentally friendly manufacturing sector.
