- <jats:title>Abstract</jats:title><jats:p>Periodate, a platform oxidizer, can be electrochemically recycled in a self‐cleaning process. Electrosynthesis of periodate is well established at boron‐doped diamond (BDD) anodes. However, recovered iodate and other iodo species for recycling can contain traces of organic impurities from previous applications. For the first time, it was shown that the organic impurities do not hamper the electrochemical re‐oxidation of used periodate. In a hydroxyl‐mediated environment, the organic compounds form CO<jats:sub>2</jats:sub>and H<jats:sub>2</jats:sub>O during the degradation process. This process is often referred to as “cold combustion” and provides orthogonal conditions to periodate synthesis. To demonstrate the strategy, different dyes, pharmaceutically active ingredients, and iodine compounds were added as model contaminations into the process of electrochemical periodate production. UV/Vis spectroscopy, NMR spectroscopy, and mass spectrometry (MS) were used to monitor the degradation of organic molecules, and liquid chromatography‐MS was used to control the purity of periodate. As a representative example, dimethyl 5‐iodoisophthalate (2 m<jats:sc>m</jats:sc>), was degraded in 90, 95, and 99 % while generating 0.042, 0.054, and 0.082 kilo equiv. of periodate, respectively. In addition, various organic iodo compounds could be fed into the periodate generation for upcycling such iodo‐containing waste, for example, contrast media.</jats:p>
