Apparatus for producing organic substance from waste and method for producing organic substance from waste

Abstract

The present invention provides an apparatus and a method which are suitable for producing an organic substance using a synthesis gas from a waste gasification furnace. The apparatus 1 for producing an organic substance from waste comprises a synthesis gas generation furnace 11 for generating a synthesis gas by partial oxidation of the waste; and an organic substance production unit 12 for producing an organic substance from the synthesis gas. The organic substance production unit 12 further comprises: a synthesis unit 13 for synthesizing an organic substance by subjecting the synthesis gas to catalytic reaction in the presence of a metal catalyst, and a fermenter 14 for producing an organic substance by subjecting the synthesis gas to microbial fermentation.
