Pierre-Antoine Guibout est le fondateur de Sargasse Project, un projet de transformation des sargasses en pâte à papier destinée à la fabrication de papier, carton, et plus largement tout objet en cellulose moulée.

Originaire de Bretagne (France), Pierre-Antoine Guibout a mené des études en droit des affaires (université de Rennes) et en droit financier (ESCP et université de Paris XI), ce qui lui a permis de fonder une société de conseils. Juriste fiscaliste, il est aussi l’inventeur d’une pâte à papier à base de sargasses, créée grâce à son expérience des échouements de sargasses sur l’île de Saint-Barthélémy, où il habite depuis 2012.

Pour pérenniser son invention, mieux valoriser la sargasse et allier l’écologie à l’économie, il a créé la start-up Sargasse Project en 2019.

Sven Jense is the founder of Climate Cleanup an entrepreneurial non-profit organization with the mission of restoring the global carbon balance by removing 1500 gigaton of CO2 out of the atmosphere using natural climate solutions (NCS). One of the most promising and scalable solutions is seaweed. Eelco Leemans joined Climate Cleanup to work on marine solutions and how the oceans can help to sequester carbon. Together they are investigating if Sargassum can help.
