Municipal solid waste: alternative source of energy to the cement kilns in the state of Madhya Pradesh, India
Rapid urbanisation has resulted in large–scale municipal solid waste (MSW) generation in India. Scientific and environment friendly disposal of MSW is a challenge for the municipal local bodies. A survey has been conducted regarding municipal solid waste generation from 342 local bodies in the State of Madhya Pradesh. Total generation of the MSW in the State is estimated around 4,500 MT/day containing around 55% incinerable waste with around 45% moisture content. There are nine major cement industries in the State, with clinker production capacity of more than 20 million MT/year. Coal is a primary fuel for clinker production and the process takes place at 1,400 to 1,450°C. The MSW is being practiced as alternative fuel and raw material (AFR) in the form of refuse derived fuel (RDF) by the cement industries. The stack emission and the engineering properties of the clinker are found unaffected after the use of refuse derive fuel (RDF) as a co–fuel. Hence, the MSW to RDF may be considered as environmentally safe option for its disposal and the better alternative source of energy, for the cement industries.
