Of South Korea’s countless kilograms of annual food scraps, very few will ever end up in a landfill. This is because of two reasons—the first is that it’s been illegal since 2005, and the second is because they have perhaps the world’s most sophisticated food waste disposal infrastructure.
While representing a significant burden on the economy, the food waste disposal nevertheless produces ample supplies of animal feed, fertilizer, and biogas that heats thousands of homes.
With the culture erring on the side of abundance rather than restraint, many of these small dishes of tofu, kimchi, bean sprouts, and other bites would be tossed in the landfill if it wasn’t illegal to do so.
The government put the ban hammer on it because the mountainous terrain isn’t ideal for landfill construction.
Instead, restauranteurs and street hawkers pay the municipality for a sticker that goes on the outside of special bins. Once filled with food scraps, they are left on the road for collectors in the morning who take 90% of all such waste in the country to specialized collection facilities.
At apartments and among residential housing areas, hi-tech food waste disposal machines are operated by a keycard owned by residents under contract with the disposal companies.
