2002-7-1 · Abstract. This paper describes a new method for pyrolyzing sewage sludge using a microwave furnace. It was found that if just the raw wet sludge is treated in the microwave only drying of the sample takes place. However if the sludge is mixed with a small amount of a suitable microwave absorber (such as the char produced in the pyrolysis
