Fuel production using municipal sewage sludge

The depletion of conventional fossil fuel deposits and the increasing energy demand are forcing the search for new energy sources.The sewage sludge produced during the wastewater treatment process is a form of waste biomass.That can be used for energy recovery with the development of appropriate technology.This paper presents the possibility of using sewage sludge, sunflower husk and food packaging waste to produce alternative fuel.Suitably prepared fuel mixtures were granulated and the fuel properties were then determined: calorific value, moisture content and ash content.The resulting calorific value of the fuel increased as the amount of packaging waste increased and the amount of sewage sludge in the mixture decreased.The research carried out made it possible to obtain fuel based on sewage sludge, which did not require a drying process.The fuel obtained was characterised by the fuel parameters required for alternative fuels used in the cement and energy industries.
