On a dreary spring day when even Greenmarket produce seemed drab, the colors inside the compost bins first caught my eye. Often the food scraps are beautiful in and of themselves; see the slideshow for more from several seasons.
It's not unusual for my local market to collect, twice a week, some 1,500 pounds of household food scraps. Surely some of the food was locally grown, but, by the looks of things, more was remotely sourced, especially during the colder months. These scraps, which otherwise would end up in a landfill — food accounts for about 17 percent of New York City's waste stream, according to GrowNYC, which operates the Greenmarkets — are instead transformed into compost for use in urban farms and gardens. See how easy it is to contribute to the compost stream.
