A system for processing solid waste including a segmented gasifier having a first segment detachably connected to a second segment, and a burner positioned downstream of the segmented gasifier and coupled to the segmented gasifier. A process for treating solid waste including introducing the solid waste into a first end of a segmented gasifier having a first segment detachably connected to a second segment. Gasifying the solid waste as it traverses from the first end of the gasifier to a second end of the segmented gasifier, and producing a gaseous output and a solid output at the second end of the segmented gasifier. Separating the gaseous output and the solid output, and introducing a portion of the gaseous output to a burner and recycling a portion of the gaseous output to the segmented gasifier as an energy source.
