Can we use old coffee grinds for fuel?

    Yes, a study by the American Chemical Society has shown that we can use them for biodiesel instead of growing rapeseed. Used coffee grounds still contain 11%-20% oil by weight, which is a similar percentage to soy. 16 billion pounds of coffee is grown each year, so the used coffee grounds can make 340 million gallons of biodiesel.
