Abstract
The present invention relates to methods and systems for processing sewage sludge using a gasification process. The gasification process takes place at high temperatures in an oxygen-starved environment, which enables carbon-containing materials in the sewage sludge to chemically react under the preferred temperature and oxygen levels, resulting in the formation of usable products, including ash, electricity, and syngas—all of which are generally environmentally benign.
