Vadodara Municipal Corporation (VMC) has set up an oxygen factory on Sun Pharma Road in the city. The factory, however, is no industrial plant, but a plantation of trees – including the banyan tree after which the city is named – that generate high amounts of oxygen.

In the first experiment of its kind, VMC has planted 236 banyan trees and 70 peepal trees in the one hectare land besides the main road. These include 32 banyan trees that were planted about six years ago. The remaining trees were planted two years ago.
