ABSTRACT:
Sewage sludge and municipal solid waste are simultaneously processed by first dissolving a catalyst, such as sodium aluminate, in the sludge, then mixing the sludge-aluminate mixture with the municipal waste to form a carbonizing mixture. After dewatering and drying, the mixture is carbonized in a furnace heated by a mixture of city gas and pyrolysis gases given off by the furnace.
