Muhammadi qau cleaning lakes from algae and creating a biomass for heating.

its very similar to initial flocculation techniques use in water treatment facilities. the key to it is timing. dont move so fast as to agitate the algae.

Looks like a DAF!!!

There are a number of things you can do. Bury it in a desert where it will sequester carbon for many, many years. Or burn it for energy, which returns the atmospheric carbon back to the atmosphere.

Gasification for a more efficient fuel usage plus the creation of biochar to sequester carbon and promote nitrogen fixation (terra preta), some species could be used as food for wildlife ecosystems and fish farms.
