Biofuel cell
Gerritse, Saakes and Stams, Netherlands, have developed a method for processing organic wastes in a bipolar biofuel cell.  The electrodes are separated by a a porous, electronically non-conductive, non-ion-selective wall, while an oxidizer is introduced in the space around the cathode.  A potential difference is formed across the pair of electrodes such that at the anode CO2 is produced and electricity is produced.  The method can be carried out with waste flows including animal manure, waste water, waste water purification sludge, kitchen and garden waste (KGW), roadside grass, residual flows from industrial processes (such as molasses, whey, draff) and/or dredgings.
