Sargassum Cleanup 2023

[@LogicalNiko]

The problem with Sargassam seaweed is that it holds heavy metals and contains a decent amount of arsenic. So if you compost it, transform it into fertilizer, or it decay your going to be eventually building up contamination. The feed use is okay, but high quantities cause problems over time, so there is a lot more of it than could be used in that manner. It’s also a massively effective carbon sink. So decomposing tends to lead to methane production, burning it releases a massive amount of CO2. Now there is a viable method if you compress it enough and add some extra weight (rock, clay, etc) you can sink it in very deep cold water and it should take almost a century or more to decompose, so you could use it as a carbon capture method. And since it’s all organic matter, very slow over a long time presents a slow breakdown of arsenic, and slow dispersion of heavy metals, and overall less impact and more nutrients for the extremaphile bacteria that live at those depths.

This is amazing . I am coming to work with you guys. Im going to need a few ships a couple with bailers installed and some crew a contract with royal carribien to keep coco cay beaches enjoyable. Can bales be stacked to create new islands? i'm naming my island stackofsargassumpilekeepout

Nice vehicle. But question is - what are going to do with this after? What is the solution for utilization? And what are useful ingredients you talk about?

[@virek542]

Man könnte das Zeug durch Pyrolyse (zum Beispiel durch konzentrierte Sonnenenergie) in Biokohle verwandeln und diese - zum Beispiel - in Bergwerken deponieren. Damit könnte man jährlich Hunderttausende von Tonnen CO2 aus der Atmosphäre entfernen...

Wrapping the seaweed in plastic....lots and lots of plastic....that doesn't strike me as a particularly good idea for the worlds oceans! There has to be a better solution than that.

God is coming. She's pretty mad
