13 August 2025 – In line with her vision of “Science for Mindanao,” Department of Science and Technology (DOST) Balik Scientist Dr. Chosel P. Lawagon led pioneering research efforts to convert industrial and agricultural waste into sustainable solutions for infrastructure and environmental resilience.

Hosted by the University of Mindanao, Dr. Lawagon’s work includes the development of engineered smart concrete from agricultural waste and lignin-based soil stabilizers designed for landslide-prone areas. Her long-term engagement has also catalyzed the establishment of two key research facilities: the Biomolecular Engineering Laboratory and the Center of Green Nanotechnology Innovations for Environmental Solutions (CGNIES) with funding support from DOST-PCIEERD.

“Dr. Lawagon is a shining example of how a Balik Scientist can spark transformation beyond laboratories, but also in communities and the environment. Through her passion for green innovation and deep commitment to Mindanao, she is helping us reimagine waste as opportunity, and science as a powerful tool for inclusive and sustainable growth,” said DOST Secretary Renato U. Solidum, Jr. “We at DOST hope her story inspires more scientists to come home and be part of nation-building.”

In her presentation, Dr. Lawagon highlighted a key project under the DOST’s Collaborative Research and Development to Leverage Philippine Economy (CRADLE) program—a partnership between the University of Mindanao and local agribusiness firm Ana’s Breeders Farm, Inc. (ABFI).

The project aimed to address specific industry challenges related to the unpleasant odor and high moisture content of organic fertilizer, which hinder its marketability. Through this collaboration, Dr. Lawagon and her team developed a nanoencapsulated fertilizer derived from biogas digestate—a solution that is nutrient-rich, environmentally safe, and economically viable. This innovation not only adds value to agricultural waste but also supports cleaner, more efficient farming practices.

Another DOST-funded initiative featured by Dr. Lawagon is the AIRGAS Project, which focuses on upcycling agricultural and industrial waste into fire-resistant geopolymer building materials. Agricultural by-products such as pineapple peels and rice husks are processed into nanocellulose and nanosilica, then combined with industrial residues like fly ash to produce durable green hollow blocks. The project aims to optimize material synthesis, enhance structural and fire-resistant properties, and promote their use in safe, sustainable construction. By integrating circular economy principles, the AIRGAS Project presents an innovative solution that addresses both construction demands and waste management challenges.

“Research and development (R&D) is at the heart of Dr. Lawagon’s transformative work. By applying advanced scientific methods and harnessing local resources, her projects turn pressing environmental challenges into innovation opportunities. Her commitment to R&D has led to sustainable materials like nanofertilizers and the AIRGAS project—solutions grounded in science and designed for real-world impact.  These efforts underscore how strategic R&D investments can lead to practical technologies that not only protect the environment but also uplift vulnerable

communities,” shared DOST Undersecretary Leah J. Buendia.

Department of Science and Technology-Balik Scientist Program has been established as early as 1975 with the goal of strengthening the scientific and technological human resources of both public and private institutions, academe included. The program aims to promote continuous knowledge sharing and accelerate the flow of new technologies amongst our local researchers by seeking support from Filipino experts and professionals abroad to avail the program and return to the Philippines. Such expertise is seen to address specific STI challenges the country faces.
