Turning waste into renewable energy, and building the people to do it

Cetogenix converts organic waste into renewable energy, and University of Waikato students are helping build the team to scale it. Since 2022, 14 students have worked across the business, with three going on to postgraduate study in the cleantech sector.

How the project moved from challenge to measurable outcome

Cetogenix uses its proprietary Ceto-Boost™ technology — a hydrothermal oxidation process that uses temperature, pressure, and air with no added chemicals — to convert complex organic waste into renewable natural gas, green ammonia, and bio-fertiliser.

Scaling that technology from laboratory concept to commercial demonstration requires people who can bridge deep science and real-world application. The University of Waikato has been a key source of that talent.

The challenge

Converting organic waste streams into commercial-grade renewable energy is technically demanding. New Zealand’s pasture-based farming system creates significant biomethane potential, estimated at around 24 PJ annually from agricultural residues alone, but capturing it at scale requires both validated technology and people who understand the science behind it.

Cetogenix needed a pipeline of graduates who could work at the intersection of chemistry, engineering, and commercial deployment.

What we changed

Since 2022, Cetogenix has hosted 14 University of Waikato students. Two have gone on to master’s degrees and one to a PhD, all with industrial focus directed at the cleantech sector.

Students work across technical and commercial functions, from translating complex science for industry audiences to contributing directly to product development.

The partnership is supported through the MBIE R&D Experience Grant and facilitated by the Tauranga Business Chamber, placing students in roles that contribute meaningfully to company progress.

What people are saying

From the COO to the students on the ground — what working at the intersection of university and industry looks like in practice.

“Students bring curiosity, energy, and fresh thinking. Since 2022, Cetogenix has hosted 14 students across New Zealand — and these experiences demonstrate how applied learning can inspire students toward emerging fields vital for New Zealand’s low carbon transition.”
