Coffee flavoured biodiesel

Coffee flavoured biodiesel could be on the cards if a suggestion in the why files is taken up seriously. There’s a whole lotta oil in them beans, apparently.

    I saw this earlier on GCC . There is a recent paper on this (subscription may be required for full text) with an economic analysis.

    The authors mention that the solid waste after biodiesel extraction could be used for producing ethanol, compost and fuel pellets.

    A note about fuel pellets: the solid waste (or the coffee grounds) will have a high organic nitrogen content. This is partly the reason why it is used as a compost. Combusting this in a conventional boiler will likely result in high NOx emissions.
