Yeah, flotation and water cleaning is a good way. Iirc, you dont need much sulfur in muluna.at least space packs and rocket parts doesn't need any
How do you make Plastic needed for Circuits without Sulfur? You need Sulfuric Acid to convert the wood into cellulose needed for plastic which is needed for Circuits?
easiest way for me was Algae farm. You have a lot of mineralised water from your water production here anyway, and carbon dioxide shoudlnt be a problem. Algae-fiber-methanol-propene- plastic 1
