note that compost matters bc food waste degrades anaerobically in the deep layers of a landfill, but aerobically in compost heaps -- the greenhouse impact of composted food waste is very different pound-for-pound from a landfill
the landfill gas capture systems that burn it off or use it for power are not installed until fairly late in the life cycle of a cell. food has a fairly short half life which means that a lot of it will decay before capture, or even final cover, is in place
total methane from landfills is down (from ~160 to ~100 mmt co2e since 1990), but the portion of this from food is way up
