  • To me that’s more ethical than killing of billions of animals, and the latter is considered ethical.

    I think most people would actually consider factory farming unethical, they just put the blame on the producers for treating animals like shit. And the producers are locked into a race to the bottom for competitive prices, so they’d blame the customers/market conditions.

    The issue with using byproducts as animal fodder is that ruminants produce a lot of methane while digesting them. This enteric fermentation in their stomachs accounts for around 6% of global greenhouse gas emissions, while the entire aviation industry sits at just 2-3%. If we give them more food that is harder to digest, they’ll emit even more methane per animal.

    Biofuels make a lot of sense though. After extracting the fuel, the remaining digestate can be used to produce biochar or be put directly on fields as fertilizer, which is nice because synthetic fertilizers account for 1-2% of greenhouse gas emissions.

    Another option is to burn the byproducts for heat or electricity in winter during short periods when there’s not enough wind and solar power to cover energy demand.
