Abstract

The present invention relates to the bioconversion of biomass into useful chemicals, for example, chemicals such as alcohols for the production of liquid fuels, and in particular to an apparatus and method for waste pre-digestion of biomass. A waste biomass pre-digester (2) for producing a waste biomass slurry from waste biomass, the pre-digester comprises a container (18) for containing waste biomass that is bounded by a floor (25) and surrounding sides (21-24) and which is accessible by means of an opening (26) by which waste biomass may be introduced to the container. The pre-digester also comprises a screw conveyor (28) within the container (18) for macerating waste biomass, and a slurry circulation system (40) comprising at least one slurry outlet (41) from the container volume, at least one slurry inlet (42) to the container volume, and a pump (40) for circulating biomass slurry from said outlet (s) to said inlet (s).
