Volkswagen Pune Plant follows the company’s ‘Think Blue. Factory.’ initiative that aims towards achieving higher environment-friendly manufacturing. Through this initiative, Volkswagen aims at reducing the impact of its production process on the environment by 25% per car globally.

Volkswagen Pune Plant has been working towards these goals since 2012. The impact on environment through manufacturing processes is measured across five key areas of ‘Energy Consumption’, ‘CO2 Emissions’, ‘Water Consumption’, ‘Waste Generation’ and ‘VOC Emissions’. Volkswagen Pune Plant has undertaken a number of projects and successfully implemented them to record remarkable results.

The major Think Blue. Factory. project of 2015 is the new Heat Recovery Unit (heat exchanger) that was commissioned at the exhaust end of the Top Coat Oven in Paint Shop. The sustainable results of this project were achieved by generating hot water using the exhaust flue gases which are vented out at 320 degree centigrade. This hot water is then used for heating application in Pre-treatment process in the Paint Shop itself.

As a result, 80% reduction in hot water generation for this purpose was achieved that saved 492,483 SCM of Natural Gas consumption and 37 MWh/a of electricity as well as reduced CO2 emissions by 1013 tons/a. The savings in consumption of Natural Gas are equivalent to 4916 MWh/a. On an average this translates to the energy consumed by nearly 1300 Indian households in a year.**
