Chung Sun-hee finely crushes eggshells, dries and saves her coffee grounds, and separates large vegetable offcuts into smaller pieces. Later, the 55-year-old professional translator will bury them in her backyard, in rotating plots. Chung is one of a growing number of city dwellers who are getting into urban farming, not just to grow their own vegetables, but also as an exercise in waste reduction. Her new habits reflect a larger change underway in South Korea's densely populated capital. Once a city where unsightly and foul-smelling landfills loomed over entire neighborhoods, Seoul now operates one of the most rigorous food waste recycling programs in the world. The South Korean government banned sending food to landfills in 2005 and, in 2013, also prohibited the dumping of garbage juice (leftover water squeezed from food waste) into the sea. Today, a staggering 95 percent of food waste is recycled ― a remarkable leap from less than 2 percent in 1995. On Chung's street, residents emerge at dusk to deposit small yellow bags into designated waste collection buckets. Since 2013, South Koreans have been required by law to discard food waste in these biodegradable bags, priced according to volume and costing the average four-person family about $6 a month. This tax pays for roughly 60 percent of the cost of collecting and processing the city's food waste, according to government data.
