Reply to comment by MassGaydiation 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

Doesn't it cost a ton of money and CO² to produce all that coffee and transport it? Or is it significantly less than production and transport of palm oil?

I think the assumption is the coffee is going to get drunk anyway, so this will at least use the grounds up afterwards

I've been using coffee ground on my compost and it's really been working out. I take several used cartridges, dump them into a container, let the mycelium spread, then put it on top of the compost that will be used in the current year.

Fair enough, i can still see the value in this though, especially for big companies

Palm oil production is incredibly bad for the environment, but all of the current alternatives are worse. New technologies such as this that could potentially be a net positive for the environment are really exciting.
