Pyrolysis

Pyrolysis is another emerging technology, sharing many of the characteristics of gasification.  With gasification partial oxidation of the waste occurs, while with pyrolysis the objective is to heat the waste in the complete absence of oxygen.  Gas, olefin liquid and char are produced in various quantities.  The gas and oil can be processed, stored and transported, if necessary, and combusted in an engine, gas turbine or boiler.  Char can be recovered from the residue and used as a fuel, or the residue passed to a gasifier and the char gasified.

Strict environmental standards now apply in all U.S. states governing the emissions from energy from waste plants, particularly of heavy metals, furans and dioxins.  All energy from waste plants must now meet these standards.  These environmental requirements are met through the installation of extensive state-of-the-art gas cleaning systems.
