Hi,
A recent blog article in oilgae.com is about a farmer who anaerobically digest the animal waste and use the biogas as fuel and the cultivate algae in the effluent and used for feeding his animals and he uses the slurry as fertilizer...

This approach is contrast to the traditional one. Lets compare these two...

Grow algae --> Anaerobic digestion--> methane

Waste --> Anaerobic digestion --> methane + Effluent + Slurry --> Effluent --> grow algae -->Biodiesel & Ethanol

We can even get biodiesel from algae oil and ethanol from the algae meal.. thus we get biodiesel, Ethanol, Methane and organic fertilizer from this process..It sounds good as we get three type of fuel from this single process..Any suggestions??

Hi,
I found a similar approach suggested by Dept. of Biological and Environmental Engineering of Michigan State University.
