Waste less with Milk-Guard.

Designed with dairy in mind to reduce wastewater product loss by up to 40%, improving your profitability and the environment.


CertusBio helps industrial processors improve yields, reduce costs and achieve better environmental outcomes. Our wastewater monitoring devices detect, quantify and prevent losses during processing and minimise the cost of treating wastewater.

Applications for our devices and services include the dairy, food & beverage, wastewater, pulp & paper, oil & gas and mining industries. Our solutions ensure industrial processors embrace the circular economy and minimise waste safeguarding the environment for future generations.



CertusBio use a lab-on-a-chip biosensor to continually monitor wastewater with no disruption to existing plant processes. The fully automated self-calibrating devices provide highly specific, interference-free continuous wastewater measurements.

The collected data is collated on a dashboard, and actions can be created from measurements such as alerts and warning for adverse events. The system is also able to be integrated into existing enterprise systems using our open API.

Our innovative biosensor technologies are based on research carried out by Lincoln Agritech, a leading R&D company based in New Zealand. CertusBio technology is covered by a patent application and significant know-how on making accurate biosensor measurements.
