New Delhi, Dec 12, 2016 : Tucked behind the boundary wall of Delhi Metro's sprawling Vinod Nagar depot, Sheikh Ajgar (24) lives with his wife and two children. While workers wearing helmets, safety boots and jackets are busy constructing the upcoming metro depot,Ajgar in his shanty is carefully removing straw and dirt from a lump of women's hair. For a week,he has been looking for a buyer to sell the 80 grams of hair which took him hours to clean."I bought this from a waste collector for Rs 106 and after cleaning, I sell it for Rs 130 or so.But for days,the man who comes to pick it up from us has not turned up.Now I collect hair myself from the Ghazipur landfill to save money.
