The key is onsite composting and having it go back to onsite gardens. Failing that, a neighborhood composting which goes back to neighborhood gardens. The idea is to close the carbon cycle to the local area. This has the additional benefit of being able to grow food that are bred to be nutritious rather than bred to be transportable, mitigating overharvesting (when producers and consumers are separated by enough distance).

Usually though, what we have in the US is that foodwaste goes to landfills (bad), and then lawns are grown with fertilizers (instead of compost). That's a much larger carbon cycle that ends up depleting the land in multiple ways. Let's not even get to how wasteful we get with water management -- pumping water, purifying them to drinking water standards, and then watering lawns with them.
