Our Technology


ENVI-Clean™ is a patented Emissions Control System designed to remove pollutants from flue gases. It is suitable for the removal of acid gases and particulate matter from high volume processes such as coal fired power stations, diesel engines and biomass combustion.

Waste to Energy

The ENVI-Pure™ system is an enhanced version of the ENVI-Clean™ system. This version has been designed to remove a broader range of contaminants with extremely high efficiency as required by Waste to Energy (WtE) and Biomass power plants.


Envi-Marine™ is a seawater scrubber that takes an alternative approach by using the Envi-Clean™ unique turbulent scrubbing head to provide interactive contact between the seawater and the exhaust gas in a turbulent zone containing a high amount of surface area for gas/liquid absorption.
