Concevoir des objets plastiques, de l\u2019engrais et m\u00eame de la bi\u00e8re \u00e0 base de sargasses est possible, assurent certains industriels et scientifiques. Plaie pour les Antilles, ces algues brunes peuvent \u00eatre une aubaine \u00e0 condition d\u2019anticiper leurs \u00e9chouages et de connaitre les techniques.<\/p>\n

Les sargasses passent leur vie \u00e0 la surface de l\u2019eau et sont \u00e0 la merci des courants. Un moment donn\u00e9 elles \u00e9chouent parce qu\u2019elles ont rencontr\u00e9 une terre sur leur passage\u201d, explique Thierry Thibaut, sp\u00e9cialiste des algues \u00e0 l\u2019Universit\u00e9 de Marseille. Depuis f\u00e9vrier, ces algues arrivent par dizaine de milliers de tonnes sur les c\u00f4tes des Antilles. Elles s\u2019amoncellent sur les rivages, et d\u00e9gagent une odeur naus\u00e9abonde.<\/p>\n

Des barri\u00e8res naturelles anti-\u00e9rosion<\/strong><\/p>\n

C\u2019est compliqu\u00e9 mais il existe des solutions a expliqu\u00e9 ce m\u00eame scientifique, responsable de l\u2019Exp\u00e9dition Sargasse Cara\u00efbes. Au Texas par exemple, soumis au m\u00eame ph\u00e9nom\u00e8ne, les Am\u00e9ricains anticipent les \u00e9chouages, un \u00e0 deux mois \u00e0 l\u2019avance \u00e0 partir des mod\u00e8les satellites. Ces derniers se servent de leur tas de sargasses qu\u2019ils recouvrent de sable et de plantes terrestres pour r\u00e9aliser des barri\u00e8res anti-\u00e9rosion.<\/p>\n

De la bi\u00e8re et des objets en plastique<\/strong><\/p>\n

D\u2019autres en font de la bi\u00e8re \u00ab Sargassum beer \u00bb, pr\u00e9cise le chercheur. Certains agriculteurs d\u2019autre part commencent \u00e0 les utiliser dans leur champ comme compost. En Bretagne, la start-up Algopack s\u2019est sp\u00e9cialis\u00e9e dans le plastique \u00e0 partir de ces algues brunes. Elle r\u00e9alise des dalles, des cadres de lunettes, des verres, des urnes fun\u00e9raires. Au d\u00e9part du projet, le chef d\u2019entreprise avait envisag\u00e9 d\u2019utiliser les algues vertes, fl\u00e9au en Bretagne, mais l\u2019algue brune, contient plus de fibres et moins d\u2019eau. Pour un m\u00eame produit, la quantit\u00e9 d\u2019algues \u00e0 traiter est inf\u00e9rieure donc moins co\u00fbteuse.<\/p>\n
