In response to Will Kidd:
I have seen reports of growing Chlorella on hog manure, and then
using it to feed to pigs afterwards. Like any quickly growing
microalga, Chlorella will have a high proportion of protein and
little structural matter (cell walls, etc.).

--Algal biomass is suitable to convert to biogas (methane) by
anaerobic fermentation. The methane, of course, could then be burned.
--No algae are woody; they don't produce lignin.
--There has been some research on growing algae on power plant flue
gas in Japan. When I saw it presented at the Marine Biotechnology
Congress in 1991, it seemed interesting but impractical.
