Our People
The team behind K³ Plus — combining world-class science, commercial expertise, and engineering excellence.
Dr. Kelvin Duncan
Chief Science Officer
Dr. Kelvin Duncan
Dr. Kelvin "Kelly" Duncan is the inventor of K³ Plus and a leading authority in ruminant biochemistry. With more than 20 years of applied research across methane suppression, redox biology, feed efficiency, and rumen metabolic optimisation, Kelly has contributed foundational science to modern livestock nutrition.
He has led over 30 peer-reviewed research projects and pioneered the core discovery that powers Herbi4's patented compound.
At Herbi4, Kelly oversees scientific direction, product development, and validation across global trials — ensuring every advancement is grounded in rigorous biochemistry and real-world farm performance.
"I've devoted my career to tackling methane — not because it was easy, but because the world couldn't afford for us to ignore it. K³ Plus is the outcome of decades of stubborn, hopeful work. If we can cut emissions at the source while empowering the people who feed the world, then we can reshape humanity's future."
