[Digestion] Microlagae spriulina feedstock

[jc clerc]

Hello David,

Thank's a lot for your reply.
For what I understand using Spirulina or Chlorella as the unique feedstock 
to produce Methane that will recycle CO2 (when burned) back into the 
Bioreactor is not good.
For what you are saying the Carbon will be too much to be a good feedstock ? 
What do you think will be a good additive, can we mix it with grass from 
garden so this would make a balance product (and allow to use this useless 
biomass!).

Once again thanks a lot for your reply and please if you can tell me why the 
Carbon in microalgae is a problem.

Kind regards
Jean-charles
