Environmental Benefits


Gasifiers generate less SOx, NOx and particulate in the conversion of the MSW, bio-solids and other solid waste than does incineration. As shown in the graphic to the left, gasifier air emissions from conversion of solid waste to energy are far less harmful to the environment than landfill.

Landfills produce the potent greenhouse gas methane, and release it into the atmosphere where it is some 20 times more effective than carbon dioxide in converting sunlight into thermal energy that is retained in the atmosphere.

Gasification of MSW and bio-solids reduces the amount of these materials going to landfill by some  80 to 90 percent, while providing a means of converting other solid wastes such as waste tires. The MSW gasifiers can be designed for multi-fuel applications so they can operate on a wide variety of solid wastes.

The graphic below shows the Irish EPA lower threshold of concern for  PM2.5 and PM10 particulate concentrations at ground level. These are compared to background near a highway, as well as worst case maximum, and annual average, ground level concentrations within 500 meters of the CEP gasification power plant.
