ABSTRACT:
Briquettes useful as fuel are produced from dehydrated sewage sludge containing 65 weight percent or more sewage sludge solids. The briquettes on a dry basis contain from about 50 to about 95 weight percent sewage sludge solids together with from about 3 to about 12 weight percent lime as binder and fungistat. Organic binders and coking agents may be included in the briquettes to improve resistance to breakage and to impart high crush strength at elevated temperatures encountered in gasifiers.
