My question is how much coffee waste actually is there? Surely nowhere near enough to make a dent in biofuel production.

it's an algae based science project, which personally I think are fascinating for using unicellular organisms as factories. But like most of this sub, it's being presented as though it's a revolution. It's just silly.

So each person on Earth produces 3 tonnes of coffee waste each year? 8 kg a day? At ~20 g a cup that's 400 cups of coffee a day per person.
