Dans le cadre de son engagement \u00e0 acc\u00e9l\u00e9rer l’utilisation de technologies durables dans la NTT INDYCAR SERIES, Bridgestone Americas (Bridgestone) a d\u00e9velopp\u00e9 un tout nouveau pneu de course dont le flanc est constitu\u00e9 de caoutchouc naturel d\u00e9riv\u00e9 de l’arbuste du d\u00e9sert, le guayule.<\/strong><\/p>\n

Bridgestone a fait les d\u00e9buts en comp\u00e9tition de ces pneus Firestone Firehawk alternatifs de course \u00e0 guayule lors du Big Machine Music City Grand Prix \u00e0 Nashville du 5 au 7 ao\u00fbt.<\/p>\n

\u00ab L’introduction du caoutchouc naturel guayule dans la plus importante s\u00e9rie de courses \u00e0 roue ouverte d’Am\u00e9rique t\u00e9moigne de la confiance que nous avons dans cette technologie et de son potentiel en tant que source \u00e9volutive, durable et nationale de caoutchouc naturel, une mati\u00e8re premi\u00e8re essentielle \u00bb, a d\u00e9clar\u00e9 Nizar Trigui, directeur de la technologie et pr\u00e9sident de groupe, Solutions Businesses, Bridgestone Americas, Inc. \u00ab Cette \u00e9tape importante repr\u00e9sente notre engagement \u00e0 r\u00e9aliser un avenir plus durable pour les pneus, la course et la mobilit\u00e9 \u00bb<\/p>\n

De la ferme \u00e0 la piste<\/strong><\/h2>\n

Bridgestone utilise la course automobile comme terrain d’essai pour d\u00e9montrer les performances de ce mat\u00e9riau en caoutchouc, qui fait l’objet de recherches approfondies depuis plus de dix ans. Le guayule est cultiv\u00e9 et trait\u00e9 dans les installations de R&D de la soci\u00e9t\u00e9 en Arizona et fabriqu\u00e9 en pneus de course Firestone Firehawk alternatifs dans son usine de production de pneus de course \u00e0 Akron, Ohio. Les pneus de course Firestone Firehawk, dont les flancs sont en caoutchouc naturel d\u00e9riv\u00e9 du guayule, ont \u00e9t\u00e9 pr\u00e9sent\u00e9s au Pit Stop Challenge de l’Indy 500 en mai 2022, avant de faire leurs d\u00e9buts en comp\u00e9tition en tant que pneu de rechange au Big Machine Music City Grand Prix. Bridgestone pr\u00e9voit incorporer du caoutchouc naturel de guayule dans un plus grand nombre de ses pneus de course en 2023.<\/p>\n

Les bienfaits du guayule<\/strong><\/h2>\n

Le guayule est un arbuste ligneux tol\u00e9rant \u00e0 la chaleur qui prosp\u00e8re dans le sud-ouest d\u00e9sertique de l’Am\u00e9rique. Cet arbuste peut \u00eatre cultiv\u00e9 avec les \u00e9quipements de culture en ligne existants, ce qui permet aux agriculteurs de r\u00e9aliser des \u00e9conomies.<\/p>\n

Bridgestone pense que le caoutchouc de guayule peut avoir un effet \u00e9conomique positif tout en contribuant \u00e0 r\u00e9duire l’\u00e9nergie et les autres impacts environnementaux associ\u00e9s au transport du caoutchouc provenant de l’\u00e9tranger.<\/p>\n

Bridgestone a lanc\u00e9 son initiative de recherche sur le guayule en 2012 en posant les premiers jalons d’un centre de traitement et de recherche sur le guayule \u00e0 Mesa, en Arizona. Aujourd’hui, l’entreprise exploite le centre de recherche de Mesa, ainsi qu’une ferme de guayule de 287 acres \u00e0 Eloy, Ariz. \u00c0 ce jour, Bridgestone a investi plus de 100 millions de dollars dans ses efforts de commercialisation du guayule, franchissant des \u00e9tapes importantes comme la production du premier pneu contenant du caoutchouc naturel d\u00e9riv\u00e9 du guayule en 2015 et l’expansion continue de son programme de s\u00e9lection mol\u00e9culaire du guayule. Bridgestone vise \u00e0 commercialiser l’utilisation du caoutchouc de guayule dans les pneus d’ici 2030.<\/p>\n

La neutralit\u00e9 de carbone<\/strong><\/h2>\n

Guayule fait partie du plan de Bridgestone visant \u00e0 atteindre la neutralit\u00e9 de carbone et \u00e0 fabriquer des pneus \u00e0 partir de mat\u00e9riaux 100 % renouvelables d’ici 2050. L’entreprise recherche activement une s\u00e9rie de solutions pour soutenir le recyclage des mat\u00e9riaux provenant des pneus en fin de vie et promouvoir le remplacement des mat\u00e9riaux non renouvelables tels que l’huile, la silice et le noir de carbone vierge dans les pneus neufs.<\/p>\n

L’initiative du pneu de course Firestone Firehawk guayule s’aligne sur l’engagement Bridgestone E8, qui consiste en 8 valeurs de type Bridgestone commen\u00e7ant par la lettre \u00ab E \u00bb (\u00e9nergie, \u00e9cologie, efficacit\u00e9, extension, \u00e9conomie, \u00e9motion, facilit\u00e9 et autonomisation) pour r\u00e9aliser une soci\u00e9t\u00e9 durable. Le lancement du pneu de course en guayule s’aligne sur les engagements de la soci\u00e9t\u00e9 en mati\u00e8re d’\u00e9motion, d’\u00e9cologie et d’\u00e9nergie.<\/p>\n
