PBS NewsHour reports that food waste reduction in Seoul, South Korea is a big deal. The capital city of 10 million has a food waste program overseen by the city’s environmental management division, which enforces the separation and collection of food scraps to be processed into animal feed. Methane and other gases, by-products of the waste plant’s efforts, are converted right back into power to supply up to 90% of each plant’s electricity needs. Suffice it to say, Seoul has it going on as far as sustainability is concerned.

Check out the video below and learn why Seoul focuses so much effort on reducing the amount of waste produced, and processing it responsibly. You’ll never look at your sweet potato peels the same way again.
