Abstract
As an efficient way of reusing sewage sludge as a solid fuel, hydrochars were made from sewage sludge and wood waste via hydrothermal carbonization (HTC). Optimal HTC conditions were determined to be 220°C for 2 h with varying the ratio of sewage sludge to wood waste. Mixing sewage sludge and wood waste improved the fuel properties (carbonization degree and lower heating value) of the hydrochar. It was determined that the nitrogen content of the hydrochar was decreased by mixing of the products. When the amount of wood waste that was mixed with sewage sludge was low, the ash content was increased. For the efficient reusing of sewage sludge as a solid fuel (hydrochar), more waste wood should be mixed with sewage sludge.
