A bioreactor is provided for the continuous or substantially continuous anaerobic digestion of organic matter. The bioreactor is preferably a small-scale, stand alone unit (10, Figure 1), which is ideally suited for small-scale industrial or domestic use. The bioreactor includes a main reaction chamber 40 for the digestion of organic matter, and two anti-chambers 36, 38 arranged between an inlet 16 for organic matter and the main reaction chamber 240. The chambers are arranged so that organic matter can pass from the inlet, through the anti-chambers and into the main reaction chamber, under gravity. Additional organic matter can be introduced into the bioreactor through the inlet into the first anti-chamber, without substantially affecting the level of oxygen in the main reaction chamber, thus maintaining the efficiency of the rate of production of methane during digestion in the main chamber. The bioreactor can be coupled to a sewage outflow from a domestic dwelling (Figure 5). |
