In the United States, the Agriculture Secretary is Tom Vilsack. He’s offering money to develop commercial-scale biorefineries or retrofit existing facilities with appropriate technology to develop advanced biofuels.
‘Advanced biofuels’ means that these fuels are to come from non-food sources. Sources such as algae and waste food. You could scroll down the article I’ve linked to here, for a success story about each of those. It’s not made clear what is used as feed for the algae, and it’s not made clear whether the waste food could have been conserved in some other way. But I’m not jumping to conclusions. Surely these advanced biofuels are better for the land than clearing forest to grow palms and maize that will go straight to biofuel.
