>But more importantly, the biggest issue is that the trapped methane in landfills is no longer bioavailable, and participating in the ecologies in the carbon cycle. This fundamentally misunderstands what the carbon cycle is. The amount of carbon in the carbon cycle has dramatically increased since the Industrial Revolution, and the quantity of carbon locked into landfills is not significant compared to the absorption of carbon by rock weathering. The carbon cycle per se is certainly not under threat from present human activities, although the Earth will slowly absorb carbon dioxide over the next billion years until it becomes uninhabitable, according to current projections. Furthermore, methane, an inert gas with low solubility, is not trapped in landfills. The capture scheme I described would eventually convert it to carbon dioxide and possibly store that carbon dioxide, but regardless, it's a very small amount of carbon compared to other emissions sources. >and atmospheric methane isn’t as big of a deal as say, soil depletion, soil temperature, oceanic acidification None of these problems are seriously related to food waste management. You might as well insist that methane emissions are not as important as nuclear war.
