Why? carbon goes into the seaweed, seaweed gets turned into bioplastic which contains that carbon. Bioplastic is used and then discarded into a composter. Composter degrades the bioplastic, the carbon (and other nutrients) are in the compost that is created?

Composting does not sequester carbon. Yes it would replace mineral carbon, but that is not what sequester means.
