Sewage Sludge Ash

At present, two major incineration systems, multiple hearth and fluidized bed, are employed in the United States. Approximately 80% of the incinerators used in the United States are multiple hearth incinerators [179-191]  

Incineration of sewage sludge (dewatered to approximately 20% sohds) reduces the weight of feed sludge requiring disposal by approximately 85%. There are approximately 170 mimidpal sewage treatment plant incinerators in the United 

Roughly 5.4-S.9 kg consists of recoverable rubber, composed of 35% natural rubber (latex) and 65% synthetic rubber 

Steel-belted radial tires are the predominant type of tire currently produced in the United States 

A typical truck tire weighs 18.2 kg and also contains from 60-70% recoverable rubber
