a Hydrothermal processing of hydrated organic wastes under high heat and high pressure produces products in three phases: gases, liquid biocrude oils, and solid hydrochar components. Images attributed to: Roberto Sorin, TheStockCube, digidreamgrafix, mputsylo, Nikolay, and sansiripech for biomass, food waste, sewage sludge, gases, biocrude oils, and solid hydrochar, respectively (stock.adobe.com). b Conventional sewage sludge processing. c Biocrude oil and hydrochar yields under several conditions of reactor pressure and temperature. Error bars denote standard deviation calculated over experiments completed in at least triplicate.
