As we move forward, we will start shortlisting the most efficient technologies,” the official said.The winning projects will also be eligible for incentives from the Delhi Pollution Control Committee, including up to Rs 5 lakh after successful expert committee assessment and up to Rs 50 lakh for solutions verified by National Physical Laboratory-equivalent laboratories and recommended for adoption by the government as per the guidelines.
