Abstract: This study deals with modelling and 4-E analysis of a solid waste gasification combined cycle plant, conceived for the municipal area of Kolkata (India). It reveals that the plant can utilise municipal waste to generate about 300 MW at a maximum efficiency of 49%. The combustor accounts for maximum exergy destruction, followed by the gasifer and the heat recovery steam generator (HRSG). The plant offers very low cost of electricity and CO₂ emission (2.8 INR/kWh and 580 g/kWh respectively, at optimum point) and also saves significant environmental damage cost by avoiding land-filling.

Keywords: 4-E analysis; CO₂ emission; cost of electricity; sustainability; waste to energy.
