Our Business and Vision

Our business is built around sensor technology for industrial applications. Our vision is to enable seamless online measurement of nitrous oxide emissions.

Enabling Emissions Reduction

N2O, nitrous oxide, is a greenhouse gas 300 times as potent as CO2. N2O is produced through biological processes during wastewater treatment. Due to the severity of nitrous oxide emissions, N2O makes up a substantial part of wastewater treatment plants climate footprint.

In 2014, we launched the world’s first and only industrial N2O Wastewater Sensor. Our goal was and still is to enable wastewater treatment plants to reduce their climate footprint by measuring and managing nitrous oxide emissions. With real-time, online N2O measurements integrated into the plant's control system, wastewater treatment operators can see the direct effect of their actions.

Denmark is at the forefront of N2O wastewater monitoring and management. This is partly driven by demands for the reduction of nitrous oxide that will be implemented in 2025. In the same year, the Danish water sector expects to make a positive contribution to the climate. This is the expected result of an ambitious water sector driven by a close co-operation between utilities, consultants, public authorities, and manufacturers.

The variations in plant size and construction, wastewater composition, weather, seasonal changes, and many other factors influence the emission of greenhouse gases. For that reason, data capture from robust and precise sensor systems play a central role in the realization of the reduction goals.
