Biofuels has always been and should only be considered as a bridging solution. Crops use a bunch of elements that we really don't need for energy transfer but really do need for nutritious food. Phosphorous most significant among them, but plenty of other soil minerals too. Put them in an engine and poof, they're in the air not being good for much.
- jagger27 8y agoWhat about algae-based solutions? I'm curious where the phosphorus and mineral losses come into play. Is it not totally feasible to repurpose the waste products of fuel production back into fertilizers?
- Arbalest 8y agoI have my doubts as to whether it would be cost effective enough to filter out everything but the long chain hydrocarbon molecules (in the case of biodiesel), though ethanol based fuels might be better as they already have to be fairly well purified. Really depends on the individual chemistry I guess. Hopefully the waste isn't too contaminated.
