Nancy,

not to be snotty, but no incinerator or depolymerizer or any chemical 
process can "convert sewage [or anything else] into energy."  When 
promoters make claims that violate basic principles of thermodynamics they 
need pretty damn good evidence....

It is possible to usefully depolymerize stuff thermally in some cases, but 
not hetergenous waste streams.
