US cities say they turn food waste into compost. Is it a problem when they do?

        August 30, 2023 The Guardian | United States | RRR: organic waste

Organic waste is turned into compost and biofuels, broken down by anaerobic digestion (AD) and microorganisms. The solid and liquid leftover AD matter is compost (digestate) and fuel (methane). Both are better than a landfill that would leak methane, but can also be flared. Rescuing surplus food, preventing waste, and composting is better than ADs.
