Abstract In the production (as co-fuel or alone) of solid refuse fuel (SRF), knowledge about the characteristics of the raw materials is required for an ecofriendly and effective combustion process. SRFs are commonly produced by drying combustible waste and removing incombustible matter, resulting in a higher combustibility as compared to the original waste. However, the characteristics of SRFs may highly vary depending on where and from which materials they were produced. Thus, we investigated the characteristics of various SRFs using thermogravimetric analysis (TGA). As a TGA sample is commonly small, on the scale of milligrams, and, unlike homogeneous fuels, SRFs are… More >

Abstract With the dramatic increase in the quantity of organic wastes, economic and environmentally friendly technologies are urgently required for reducing the volume of sludge and remediating its harmful impacts. In this study, drying experiments were performed on sludge through fry-drying technology and the characteristics of the resulting fuels were investigated to identify proper methods for treating sewage sludge, wastewater sludge, swine excreta, and food waste and converting them into fuels. The four types of organic wastes were fry-dried, and the best drying conditions were found to be 140 °C for 8 min for sewage sludge and 150 °C for 10… More >
