Abstract
Pellets or briquettes useful as fuel are produced from sewage sludge solids. Mechanically stable pellets or briquettes result from combining a major portion of sewage sludge solids with lesser amounts of lime and binder materials suitable for imparting stability to the product and pressing or extruding the combined components into desired shapes. Coal may be included in the pellet or briquette composition for improved fuel value.
