[Gasification] use of calcium salts in biogas generation

Dear List,
green biomass can easily be converted into lactic acid, and the same can be
removed from the solution by treating it with calcium hydroxide. I want to
know, if the calcium lactate that is thus formed can be used as feedstock
in a biogas plant. Equations written on paper show that the lactate ion
would be converted into methane and carbon dioxide, but what would be the
fate of the calcium ion? Would it combine with the carbon dioxide to form
calcium carbonate? If that were to happen, we should get biogas with a
higher methane content than the usual 60%.
I would thankfully receive your views, comments and suggestions.
