Anaerobic digestion (AD) is the most extensively employed sludge stabilisation process and, as with most sludge and wastewater unit processes, the design and performance of AD depends on the feed characteristics. Professor Simon Judd explains

Recycling the product streams from a hydrothermal carbonisation process to the anaerobic digester promotes biogas yield in terms of methane volume per unit feed COD, using HTC process conditions of 190 °C and a 1 h reaction time, this research suggests.
