C'est pas sorcier - Season 1 Episode 241 Le plastique, ça nous emballe
Le camion de C'est pas sorcier prend la route de la Plastics Vallée. De là, entre Ain et Jura, sortent chaque jour aspirateurs, pare-chocs, lunettes, balles de tennis, robes de haute couture… Autant d'objets qui, tous de plastique vêtus, ont envahi notre quotidien. Fred, Jamy et Sabine nous expliquent la fabrication et le recyclage des matières plastiques. Comment à partir du pétrole brut récupère-t-on les hydrocarbures qui serviront à faire du plastique ? Qu'est-ce que la polymérisation ? Les sacs plastique et les bouteilles de lait sont en polyéthylène. Les stylos à bille et les boîtiers de CD, eux, sont en polystyrène. Quelles sont les différentes familles de plastique ? Comment à partir de granulés de plastique fabrique-t-on des objets ? Pourquoi certains plastiques sont-ils durs et d'autres mous ? Combien de temps le plastique met-il pour se dégrader ?
