Every year, about 15 million pounds of alligator fat is dumped into landfills as a byproduct of alligator meat processing. It would certainly be better to reuse this gloopy mess for a greater purpose, no? As it turns out, alligator fat is a prime candidate for animal-derived biodiesel, according to researchers in Louisiana.
It's abundantly clear that we need to get off fossil fuels for various reasons (try Googling "oil spill"), but our infrastructures are far better tuned for the hydrocarbon fuels of the past century than the renewables of the next. So why don't we just make fuels that work in our existing technology from renewable energy?
Algae have come a long way in our post-fossil-fuels energy situation: Now the same green scum that covers water and other surfaces could soon be enlisted to make biodegradable green plastics for your picnic cutlery.
