The key points: Food is the basis of the human economy. Collecting and composting food waste closes the loop and completes the nutrient cycle in the soil we use to grow food.
Not to mention: half the problems we have with traditional dirty landfills is that the unsorted food waste starts to decompose (releasing methane) and creates a hot environment that causes everything else to degrade in a toxic manner. As soon as you take it out, you have a "dry" landfill, where currently unrecyclable single-use things can be stored in GPS-tagged storage sites, until someone finds a better use for them and/or we start to phase them out.
The only relevant data I could find in those links was from "ecologically sustainable recovery of bio-waste". A figure on page 38 suggests that bio-waste recovery could save between 29 and 194kg CO2e per ton of waste, but the breakdown does not appear to include the emissions involved in the collection of domestic food waste and the accompanying text acknowledges that the data is not based on a full lifecycle analysis. I cannot find the source document cited in the figure, possibly because of a translation issue from the original German.
I'd suggest checking out a resource like "City to Soil": https://www.gerrygillespie.net/city-to-soil.html or "Ecologically sustainable recovery of bio-waste" https://www.umweltbundesamt.de/sites/default/files/medien/37... or anything at "Zero Waste Europe" https://zerowasteeurope.eu/.
