Our latest work on the green extraction of keratin from chicken feathers is now published in Green Chemistry, a D1 Scopus-indexed journal (CiteScore 16.1, 93rd percentile), widely regarded as a global home for cutting-edge research in sustainable technologies and one of the flagship journals of the prestigious Royal Society of Chemistry.

In the paper, “Metal-Assisted Hydrogen-Bond Restructuring in a Ternary Deep Eutectic Solvent for Near-Complete Keratin Dissolution and Circular Biomass Valorization,” our team achieved 99.62% keratin recovery using a specially designed deep eutectic solvent under mild and energy-efficient conditions. In simple terms, we found a way to unlock one of nature’s toughest waste materials and turn it into a high-value, reusable resource through a process where the solvent itself can be regenerated and used again.

This fully homegrown achievement from the Center for Sustainable Polymers (CSP), MSU-IIT, made possible through the support of DOST-PCIEERD, highlights the strength of our research team and our capability to produce globally competitive, top-tier science from our own laboratories in Mindanao.

The paper, lead-authored by Andrei Etom and co-authored by Ann Pearl Triana, Jady Lee Esler Amarillas, Rhea Casipong, Jayson Rey Gilbolingo, April John Galagnara, Roger Dingcong, Jr., Arnold Alguno, Roberto Malaluan, and Arnold Lubguban, is now available online as an Accepted Manuscript in its first published form, and truly worth the long journey it took to get here.

Delighted to share our recent publication in RSC Applied Polymers! The study explores the synthesis of carbon-doped silica nanoparticles (SNP) from rice husk ash using κ-carrageenan and their integration into coconut oil-based rigid polyurethane foam (RPUF). Remarkably, incorporating just 0.3% SNP by mass boosted the compressive strength of RPUF by 92.42% while also improving thermal stability. This demonstrates the potential of sustainably derived nanomaterials to create functional and eco-friendly foams for industrial applications.

Huge congratulations to the entire team: Carlo Kurt F. Osorio, Christine Joy M. Omisol, Dan Michael A. Asequia, Blessy Joy M. Aguinid, Daisy Jane D. Erjeno, Kassandra Jayza Gift D. Tejas, Roger G.

From Tuna Bones to Healing Solutions!

Researchers from MSU-IIT's Center for Sustainable Polymers, under the Biomedical Polymers Team led by Dr. Ronald Bual, Chairman of the Department of Chemical Engineering & Technology, have developed a process to transform tuna bones—often discarded as fishery waste—into a valuable material for medicine.

Authored by Zesreal Cain Bantilan, Marionilo Labares Jr., Johnel Alimasag, Kit Dominick Don Valle, Chancy Louisse Barlisan, Elizer Eleccion, and Dr. Ronald Bual, the study was published in Applied Biosciences (MDPI) and demonstrates that tuna bones can serve as a sustainable source of extracellular matrix (ECM) for biomedical applications by preserving collagen and other natural compounds that support tissue repair and regeneration.
