Seoul's Food Waste Solved: NYC Follows Lead
17 Sep
Summary
- South Korea reduced food waste to landfill from 97% to nearly nothing.
- Smart bins track household waste, charging users per use.
- Food scraps are converted into energy, reducing fossil fuel reliance.
South Korea has drastically reduced household food waste sent to landfills, from 97% down to almost nothing, a system now being emulated by New York City. This ambitious waste management experiment began as a response to a 20th-century waste crisis driven by rapid urbanization.
Since the 1990s, South Korea's food waste recycling rate has soared to nearly 97% as of 2023. A key element is the widespread use of smart bins, equipped with RFID scanners, which weigh household food scraps and apply a charge. This technology, used by over 8.61 million households, fosters greater awareness of waste generation.
These collected food scraps are processed at over 340 energy facilities nationwide, such as the Daejeon Bio Energy Centre, which recycles 70-75% of waste into electricity. This process prevents the release of methane, a potent greenhouse gas from landfills, and reduces the need for fossil fuels, with a government aim to displace $170m in fossil fuels by 2026.
New York City mandated food waste separation in October 2024, aiming to replicate South Korea's success. Despite issuing over 63,000 violation notices, compliance remains a challenge for its 3.4 million households. The city utilizes both mandatory curbside collection and over 400 free, solar-powered smart composting bins.
NYC processes organic waste into fertilizer or biogas. Experts suggest South Korea's RFID bin system could foster direct accountability among residents, essential for a circular economy. However, improved education and incentives are crucial to boost participation in organic waste separation.
