A system includes a gasifier having a first enclosure having a first inlet, a first outlet, and a first interior volume. The first inlet is configured to receive a first fuel feedstock into the first interior volume, and the first outlet is configured to output a first syngas away from the first interior volume. The system also includes a plasma gasifier disposed downstream from the first outlet and coupled to a waste stream produced by the gasifier from the first fuel feedstock.
