Step-by-step solution

The various solid wastes in the form of slags and sludges that are emerged from steel plants are blast furnace slag. Fly ash is a fine by-product recovered from gases of burning coal in thermal power plants. Gypsum is the waste of fertiliser industry. Non-cellulosic part of plant is wastes of paper industry and it is biodegradable.
