[1] Looking like fugitives from a factory floor, at least 1,000 55-gallon drums dotted Central Park in the 1980s, marring what may be the greatest invented landscape in [4] America. They were big — not to mention unsightly — but not big enough to contain all the cans, bottles, cups, napkins, newspapers, magazines, paper bags, pizza boxes, hot-dog [7] wrappers and other refuse from 12 million visitors a year. Trash piled up in them and around them. To help keep up with the overflowing cans, rear-loading garbage trucks lumbered [10] back and forth like dinosaurs across lawns and meadows, hills and valleys, paths and walkways. It was a brutish way to treat what was supposed to be a green gem. No wonder the park felt
[13] out of control.
Today, Central Park is a far different place. The number of visitors has soared to 42 million visitors annually. [16] They generate 2,000 tons of trash and 58 tons of recyclables a year. Despite all that garbage, it is possible to drive around the sprawling park and count the pieces of stray litter on two [19] hands. In place of 55-gallon drums and 68-gallon plastic bins are neat arrays of handsome, patented, coated-aluminum receptacles with 32-gallon plastic bags inside. The cans are [22] colored black for garbage, gray for bottles and cans, and green for paper and cardboard. Instead of being serviced by ungainly rear-loaders, the receptacles are emptied day and night by [25] workers scooting around in 86 small carts. They take the bags to one of eight pickup areas in the 843-acre park, from which the bags are hauled to transfer stations in the Bronx and [28] Queens.
