Parisians converting food waste into compost

What they’re not saying is that this helps put bioavailable nitrogen and carbon back into the soil, reducing dependence on chemical fertilizers, which come from fossil fuels. Compost is a valuable resource, particularly with more people deciding to source their food closer to home (it’s bulkier than chemical fertilizers to transport). And at scale, it’s probably a lot cheaper in terms of direct costs (no social cost of carbon added), but I don’t know for certain. (I’ll look it up or run the numbers.)
