Our government will expand and strengthen the e-vehicle ecosystem by supporting manufacturing and charging infrastructure. Greater adoption of e-buses for public transport networks will be encouraged through payment security mechanism. Bio manufacturing and bio foundry. For promoting green growth a new scheme of bio manufacturing and bio foundry will be launched. This will provide environment friendly alternatives such as biodegradable polymers, bioplastics, biopharmaceuticals and bioagree inputs. This scheme will also help in transforming today's consumptive manufacturing paradigm to the one based on regenerative principles. Blue economy 2.0.
