Abstract

A method of anaerobically digesting organic material, comprising: providing a reaction chamber (12) comprising first and second cells (20,22) linked by a passageway (24) for flow of organic waste slurry from a bottom region of one cell to a bottom region of another cell; placing an organic waste slurry (S) in the reaction chamber (12) to fill at least the bottom region of each cell; displacing organic waste slurry (S) through the passageway (24) from the first cell (20) to the second cell (22) to build a head ∆h of organic waste slurry (S) in the second cell (22); and discharging the head ∆h of organic waste slurry (S) from the second cell (22) to agitate organic waste slurry in the reaction chamber (12).
