Abstract

La présente invention concerne une composition de résine contenant 5 à 50 parties en poids d'une poudre de coquille d'œuf par rapport à 100 parties en poids d'un polymère. La composition de résine selon la présente invention, qui est un matériau respectueux de l'environnement, permet une réduction de coût grâce au recyclage de coquilles d'œuf, qui correspond à un déchet alimentaire, destinées à être utilisées en tant que matière plastique. De plus, la composition de résine selon la présente invention présente une faible charge environnementale étant donné que la quantité de dioxyde de carbone générée pendant l'élimination par incinération est faible étant donné qu'un matériau non combustible au lieu d'une biomasse est ajouté en tant que matériau qui est ajouté pour la réduction du coût. En outre, la composition de résine selon la présente invention présente une excellente disponibilité avec une poudre de coquille et une résine de base, et permet donc de fabriquer un article moulé ayant un bon aspect.
