Hydrothermal Oxidation

Hydrothermal oxidation is an advanced thermal conversion process that utilises the unique chemistry of water and oxygen to break down complex organic wastes into simple useful compounds:

Operating at moderate temperatures and pressures, the process can be optimised for a wide range of applications and product yields.

The oxidation reactions generate enough heat to sustain the process without needing external energy input.

Challenging chemical and biological contaminants, such as micro-plastics and pathogens, are destroyed or isolated through hydrothermal oxidation.

Unlike many other thermal processes, hydrothermal oxidation does not:

produce problematic by-products, such as toxic effluents or air pollutants.

require energy intensive pre-drying.

produce new products requiring new markets, such as biochar.

The unique attributes of hydrothermal oxidation enable maximum resource recovery and emission efficiency.

Cetogenix has translated this technology into our proprietary platform - Ceto-Boost™


Traditional implementations of hydrothermal oxidation have typically been centred around large-scale bespoke reactor systems with a primary focus on waste destruction.

Cetogenix has reimagined hydrothermal oxidation to create a modular product optimised for waste deconstruction to maximise resource recovery.

The result is a 95 percent reduction in organic waste volumes, but with exceptional value addition and climate change mitigation.

Ceto-Boost™ hydrothermal oxidation systems are standardised modules enabling complete flexibility and scalability in both established infrastructure and new-build facilities.


Cetogenix builds off a >15-year R&D focus on advanced hydrothermal processing and waste-to-value technologies by our co-founders.

Since 2022, Cetogenix has established a first-of-kind TRL-5 Ceto-Boost™ prototype system at our Rotorua site, formalised commercial relationships across global target markets, and built up our IP “moat” through new patent filings and IP licenses.
