Case study of GHG reduction and sustainable solutions in a Chemical Industry with reference to the climate change action plan of the Puducherry region, India

jasem Front Page
Increasing vehicular traffic, expanding tourism and institutional sector contribute to the green house gases emissions in Puducherry region. Further, better health and educational facilities and cosmopolitan status of the living style have attracted many people migrating to the city and also transit to the city from the neighbouring districts. An effort has been made to estimate the greenhouse gases inventorisation of Puducherry in 2013. This has revealed that 3.46 million tonnes of CO2 equivalent is emitted annually. The Government of India has taken a policy decision that all the new chlor-alkali plants will be of membrane based technology and had also set a deadline for phasing out of the highly polluting mercury technology. The total anticipated energy savings is around 30 % compared to the conventional mercury based chlor-alkali process. Hence, an attempt is made to analyse and explore the options / scope for the present emission of GHG emission and its potential reduction by appropriate interventions in a chlor-alkai industry situated in Puducherry region.
