NYC Department of Sanitation:

The NYC Department of Sanitation is the world’s largest sanitation department. DSNY collects more than 10,500 tons of residential and institutional garbage and 1,760 tons of the recyclables – each day. While efficiently managing solid waste and clearing litter or snow from 6,300 miles of streets, the Department is also a leader in environmentalism — committing to sending zero waste to landfills.
