What about turning milk into a biofuel? Can yeast grow in milk and produce alcohol?
- Something1234 8y agoI would love to see biofuel done with surplus milk. It's full of excess fat, so it shouldn't be too hard to convert it to biodiesel or candles. I have heard of vodka made from milk[1]. I would really like to try that one. There's also milk beers[2]. Although I don't like the taste of them.

- Something1234 8y agoIt would be nice to get rid of the excess cows, but since that won't happen. It's better to make something out of the excess rather than let it go to waste. Especially considering that a large amount of fat is produced from skim milk. This fat just goes into making cheese, and deflating the cost of cheese. More cheese than most people would like to eat.
- orev 8y agoSeems like that would be awfully inefficient. We use oil (fertilizer) to grow corn and soybeans, which we then feed to cows, which then convert it to milk. Each step in the process reduces the efficiency. Why not just use the oil for fuel? Or convert the corn the ethanol if that type of oil is not useful as fuel? The efficiency of ethanol is already in question due to the use of corn.
- Something1234 8y agoIt could be a way to use the excess or that milk which is about to spoil. There's a large amount of fat left over from the production of skim milk. This fat usually gets turned into cheese, that's why pizzas are more cheesy than in the past.
