St. Dominic College of Asia
BIO-FLOW Project: Black Soldier Fly Insect Output for Frass- Level Organic Water Treatment
Finalist, Creating Impact
About
The BIO-FLOW Project is a university-led sustainability initiative of St. Dominic College of Asia in Bacoor, Cavite, Philippines, developed to address bacterial contamination in urban and coastal creek systems through a low-cost, circular, nature-based solution. The project converts Black Soldier Fly Larvae (BSFL) frass, an insect bioconversion byproduct, into biodegradable frass balls made with clay soil, rice bran, and Effective Microorganisms for water treatment. Tested in two high-risk Bacoor creeks, the intervention reduced bacterial load from 1,150 × 10⁷ CFU in untreated water to 147 × 10⁷ CFU after application, demonstrating strong antibacterial performance. BIO-FLOW advances SDGs 3, 6, 11, 12 and 13 by combining waste-to-value innovation, environmental protection, applied student research, and community engagement. The project shows how higher education institutions can create measurable local impact using affordable, locally sourced materials while building environmental stewardship and replicable community resilience models.
Top 3 learnings
- We achieved meaningful water remediation using low-cost, locally sourced circular materials.
- We learned community relevance strengthens both scientific value and sustainability impact.
- We found waste-derived solutions can be credible, scalable, and educationally transformative.
