Reply to comment by jamanimals in Researchers fed microalgae on leftover coffee grounds to produce high-quality biodiesel | It could decrease reliance on palm oil to produce biofuel. by chrisdh79

I suspect coffee was chosen because there are a lot of wasted coffee grounds. There likely isn't anything specifically about coffee that is needed here, you could probably use any number of similar substrates that are cheaper to grow

Oh, I agree, but even corn for ethanol was only supposed to be using waste products and not corn grown for ethanol, but once you give the industry an inch to grab onto, they'll take all they can get.
