Every year, with Diwali in sight, potter Sher Singh Prajapati works extra hours to have earthen lamps ready. Every potter sells thousands of the diyas during the festival period. This year, 50-year-old Prajapati is unsure of following his annual routine because he has no kiln to bake his products. In the past year, inhabitants of the potter’s colony in southwest Delhi’s Uttam Nagar have been ordered to shut down their kilns to prevent pollution. A report prepared by Delhi Pollution Control Committee on August 25 revealed that 166 bhattis in the area had been dismantled and notices demanding environmental compensation issued to the potters.
