The Cover picture shows how humins, byproducts from sugar conversion in biorefineries, can be broken down to valuable humin oil. Biomass and residue valorization to high‐added‐value chemicals is high on the global research agenda. The current routes to synthesize the platform chemicals 5‐hydroxymethylfurfural (HMF) and levulinic acid (LA) inevitably lead to the formation of substantial amounts of solid byproducts (humins). These not only cause operational issues (fouling) but also lower the carbon efficiencies of the conversions considerably. The details for the proof of principle for the depolymerization of these humins and to convert the fragments into more valuable chemicals (particularly alkylphenolics and aromatics) can be found in the Full Paper by Wang et al. on page 951 in Issue 9, 2016 (DOI: 10.1002/cssc.201501371).
