New York City is the largest city in the United States, so it’s only fitting that it has the biggest sanitation department. According to its website the DSNY is composed of over 7,900 uniformed sanitation workers and supervisors, over 2,040 civilian workers, 2,230 collection trucks and 450 mechanical street sweepers. The DSNY collects 10,500 tons of residential and institutional garbage as well as 1,760 tons of recyclables. This does not include commercial waste, which is handled by private companies.
