This paper presents Hydrothermal oxidation (HTO) technology as a compelling alternative to agricultural application of UK wastewater bioresources. Adoption of HTO into a treatment works will be presented, showing the potential for elegant integration of this sludge deconstruction process. Working directly on wet sludge (3-10% solids content), the burden of drying is avoided. The process operates under thermal energy self-sufficiency, and generates final products which can be integrated back into the main treatment works or go directly into established markets. The net result is enhancement of the energy and nutrient value opportunities of a wastewater treatment site. Technical performance of HTO will be presented, including the high solids destruction (>90% VSS) and conversion to readily-fermentable short chain fatty acids (up to 50% of the final product COD). Emphasis will placed be on describing the reaction conditions, mass and energy balances that characterise the technology. In the context of the UK water sector, we will outline the progress of an OfWat funded HTO programme.
