Work Design of a Solid Waste Management Facility

With a great influx of Iron, Steel & Power Industry in an area comes the problem of solid waste management. Industrial waste is defined as the worthless residues obtained after the production process in the industry. The waste is categorized as Slag, Fly Ash, Sludge & Black Dust. Here we are going to elaborate on the problems created by Fly Ash and Black Dust (Dolochar). Fly ash is one of the residues generated in the combustion of coal in coal based power plant facilities. Its composition consists of both hazardous and unhazardous elements.

The Toxic elements consist of Arsenic, Beryllium, Boron, Chromium, Cobalt Mercury, Sulphur and Molybdenum. While the Silicone Dioxide, Calcium Oxide and unburnt coal as the unhazardous materials. While Black Dust (Dolochar) is the residue obtained from the production of Sponge Iron Plant. Dolochar is generally consists of unburnt coal fused with Iron Oxide and calcium oxide.

Given the composition of the elements in both the waste their re-utilization for varied purposes is very limited. Given the weightlessness of the dusts it proves hard to be contained in closed spaces. Also given the makeup of these their decomposition proves to be an expensive process.
