[Problem] To effectively utilize rice straw and rice hulls disposed of in large amounts as agricultural waste. [Solution] The present invention was accomplished by discovering that silica can be recovered with high efficiency by putting heated titanium oxide in contact with a silica-containing plant body. L'invention a pour but une utilisation efficace de la paille de riz et de balles de riz disposés en grandes quantités en tant que déchets agricoles. La présente invention résulte de la découverte que la récupération de la silice est permise avec une grande efficacité par la mise en contact d'oxyde de titane chauffé avec un corps contenant de la silice. 【課題】農業廃棄物として大量に排出される稲わら、籾殻の有効利用。 【解決手段】加熱した酸化チタンをシリカ含有植物体に接触することにより、高効率でシリカを回収できることを見出し、本発明を完成した。
