[Digestion] Microlagae spriulina feedstock

[David Fulford]

Jean- Charles and all, Hi

As the language of the list is English, I will use that language. My French 
is very poor.

Microalgae would make a good additive for the biogas process, especially if 
other feedstocks had reasonable levels of nitrogen. The carbon content of 
microalgae is probably too high for therm to be used as a single feed.

You could make a solar-powered generation system, by growing the algae, 
using the effluent of the biogas digester as a growth medium and then 
feeding the algae into the digester. The nitrogen would be recycled. I 
suspect the area of land (actually lagoon) to do this would be a problem. 
People have grown microalgae in long plastic tubes on vertical frames to 
reduce space, so it might be a possible way forward.

Cheers,

David
