STAX Engineering builds barges that purify the exhaust gas emanating from the stacks of oceangoing vessels, thereby improving the quality of life for millions living near port cities. STAX builds/owns/operates STAX barges and charges an hourly fee. STAX removes nearly 100% of particulate matter (PM), oxides of nitrogen (NOx), and Sulfur Dioxide (SO2) from the exhaust gas of oceangoing vessels at berth.


TRAX connects to stationary or slow-moving locomotives in a rail yard. TRAX removes nearly 100% of Particulate Matter (PM) and oxides of nitrogen (NOx) from locomotive exhaust. TRAX also significantly reduces the noise level when locomotives are being tested at high power. Each TRAX system is custom designed for each rail yard. Please contact us for further details.
