Application of Carbonaceous Household Wastes as Fuel Feedstock at Thermo Metallurgical Equipment and Processes

Abstract

The possibility of utilization of municipal solid waste in the conveyor roasting cement production machine along with obtaining secondary thermal energy, what could reach 15-20% of the principal quantity of the heat energy required for the conduct of the process was considered. The inclusion of ash obtained from the incineration of municipal solid waste after preprocessing into the cement clinker composition was proposed. The reduction of the emission of dioxins and furans in the atmosphere and the impact on the environment was achieved as a result.

A Study of Water Permeability of Coal Ash and Slag to Assess the Possibility of Their Use as Road Pavement Layers

“…The total area of the territories occupied by ash dumps is about 300 km 2 . This circumstance causes serious socioeconomic and environmental problems and encourages the search for ways to utilize these wastes [5,6,10,17,19]. One promising application of coal ash and slag is road construction, in which they are used both as a local binder and aggregate of bitumen concrete mixtures or as building material for filling the subgrade [16].…”
