NOVELTY - Waste is introduced into cell having pair of electrodes. Pair of electrodes, which are separated by porous, electronically non-conductive, non-ion-selective partition wall. Oxidizer is introduced into portion around cathode. Potential difference is formed across electrodes such that carbon dioxide is produced at anode, resulting in electricity generation, and the organic waste is converted.    USE - For conversing organic wastes such as organic waste comprising animal manure, waste water, waste water purification sludge, kitchen and garden waste, roadside grass, residual flows from industrial processes such as molasses, whey and draff, and/or dredgings, with the cell used for conversion also used as biosensor for determination and quantification of biological activity (all claimed).    ADVANTAGE - The conversion of organic waste is carried out at low cost due to the use of electronically non-conductive, non-ion-selective partition. The conversion of organic waste also enables generation of electricity, and is environment friendly.    DETAILED DESCRIPTION - Waste is introduced into cell having pair of electrodes. Pair of electrodes have anode (8) and cathode (7), which are separated by porous, electronically non-conductive, non-ion-selective partition wall (1). Oxidizer is introduced into portion around cathode. Potential difference is formed across electrodes such that carbon dioxide is produced at anode, resulting in electricity generation, and the organic waste is converted.    INDEPENDENT CLAIMS are included for the following:    (1) device for processing organic waste; and    (2) kit for processing organic waste, which comprises pair of electrodes with at least two three-dimensional electrodes, preferably graphite felt electrodes, and a fiberglass mat.
