Abstract: Provided herein is a gasifier, preferably a fixed bed, slagging, updraft oxygen gasification reactor or gasifier with features to facilitate gasification of heterogeneous waste streams producing a syngas with minimal level of condensable tars whilst simultaneously removing molten slag from the bottom of the bed via a cooled slag collector (“CSC”); syngas and other compositions produced therefrom; and processes including it.
