UM Inter-Branch UN-SDG Student Conference 2025: Pioneering Sustainable Solutions Through Geopolymer Technology

The UM Inter-Branch UN-SDG Student Conference 2025, with its theme “Future Forward: Unleashing Student Innovation for a Sustainable Future through UN SDG Solutions”, underscored the University of Mindanao’s commitment to fostering innovation and sustainability. Organized by the Council of College Student Government (CCSG), the conference brought together participants from various disciplines to present actionable solutions aligned with the United Nations’ Sustainable Development Goals (SDGs).

The College of Engineering Education (CEE) made an outstanding impact during the event, particularly in the Pitching Competition, where their innovative ideas and dedication earned them the following accolades: Best in Poster Presentation, Best Oral Presenter: LJ Idane Aranas, 1st Place in Overall Pitching Competition: UM CEE - Main Team.

The winning project, authored by LJ Idane Aranas (BSCE), Jianne Bornea (BSCE), Marco Ceazar Antonio (BSCpE), Jules Bryl Alcala (BSChE), and Jayvenn Drexcel Mancera (BSCpE), is titled “Sustainable Transition: Localizing the Path towards Net Zero through Geopolymer Technology.” It explores the use of geopolymer concrete as a sustainable alternative to traditional cement.

This groundbreaking research addresses the construction industry’s substantial contribution to global carbon emissions, which accounts for 9% of human-induced CO2 emissions. By utilizing fly ash, an industrial by-product, and incorporating agricultural waste such as banana pseudostems and pineapple peels, geopolymer concrete significantly reduces carbon emissions by 80-90% compared to traditional cement production. The project aligns with multiple SDGs, including Affordable and Clean Energy (SDG 7): By reducing the energy demands of traditional cement production by up to 59%. Sustainable Cities and Communities (SDG 11): Through the development of eco-friendly construction materials. Responsible Consumption and Production (SDG 12): By reusing industrial and agricultural waste, minimizing resource depletion. Climate Action (SDG 13): By cutting carbon emissions through sustainable production methods.

The research also incorporates nanomaterials synthesized from agricultural residues to enhance the concrete’s mechanical performance and sustainability. These advancements demonstrate the potential of geopolymer concrete to revolutionize green construction practices and address critical issues such as resource depletion and environmental degradation.

Adding to the College of Engineering Education’s achievements, Victor Shanly Millan (BSCE) received three certificates recognizing his exceptional leadership and contributions during the conference, further showcasing the remarkable talents within the college. Special appreciation is extended to Dr. Roumel Alvarez, whose mentorship and expertise were invaluable throughout the research and development process. His guidance highlights the importance of collaboration between educators and students in driving impactful solutions to global challenges.

The success of the UM Inter-Branch UN-SDG Student Conference 2025 reaffirms the role of academic institutions in fostering innovation, sustainability, and leadership. The achievements of the CEE demonstrate how engineering students can lead the charge toward a greener and more sustainable future.
