Environ 95 % des peintures sont fabriqu\u00e9es \u00e0 partir de dioxyde de titane (TiO2<\/sub>). Ce dernier est un ingr\u00e9dient essentiel qui permet de produire des peintures durables pour l\u2019int\u00e9rieur comme l\u2019ext\u00e9rieur. Les peintures repr\u00e9sentent environ 50 % de la consommation mondiale de TiO2<\/sub>. Les peintures de haute qualit\u00e9 formul\u00e9es avec une forte teneur en TiO2<\/sub>\u00a0ont l\u2019empreinte environnementale la plus faible, car celles-ci ont la plus grande opacit\u00e9, ce qui signifie qu\u2019il faut moins de couches de peinture pour obtenir le r\u00e9sultat souhait\u00e9.<\/p>\n

Les peintures et les rev\u00eatements sont les principaux domaines d\u2019application du TiO2<\/sub>. L\u2019AMRT a travaill\u00e9 en \u00e9troite collaboration avec le Conseil europ\u00e9en de l\u2019industrie des peintures, des encres d\u2019imprimerie et des couleurs d\u2019artistes (CEPE) afin de garantir une harmonisation entre la m\u00e9thodologie et le contenu des bases de donn\u00e9es de l\u2019ICM.<\/p>\n

La Commission europ\u00e9enne a identifi\u00e9 l\u2019analyse\u00a0du cycle de vie\u00a0<\/a>(ACV) comme \u00e9tant le meilleur cadre pour \u00e9valuer les impacts potentiels des produits sur l\u2019environnement et a cr\u00e9\u00e9 la Plateforme europ\u00e9enne sur l\u2019analyse du cycle de vie (EPLCA), qui d\u00e9veloppe la m\u00e9thodologie pour l\u2019empreinte environnementale des produits de l\u2019UE (PEF) et h\u00e9berge diverses bases de donn\u00e9es. Le CEPE fournit les donn\u00e9es relatives aux produits chimiques pour peintures en collaboration avec Ecomatters, qui fait l\u2019objet de contr\u00f4les de conformit\u00e9 rigoureux de la part de la Commission europ\u00e9enne. Gr\u00e2ce \u00e0 la coop\u00e9ration avec le CEPE, en 2023, les donn\u00e9es de l\u2019ICMT pour le TiO2<\/sub>\u00a0ont \u00e9t\u00e9 enti\u00e8rement int\u00e9gr\u00e9es dans cette base de donn\u00e9es selon la derni\u00e8re norme EF 3.1.

En 2015, le CEPE a demand\u00e9 \u00e0 Ecomatters d\u2019\u00e9valuer les peintures utilis\u00e9es pour rev\u00eatir les murs et plafonds int\u00e9rieurs, les murs ext\u00e9rieurs, ainsi que les garnitures et rev\u00eatements int\u00e9rieurs et ext\u00e9rieurs pendant toute la dur\u00e9e de vie d\u2019un b\u00e2timent. Les r\u00e9sultats ont montr\u00e9 que les peintures de haute qualit\u00e9 formul\u00e9es avec des niveaux \u00e9lev\u00e9s de pigment TiO2<\/sub>\u00a0ont le PEF le plus bas par rapport aux peintures de qualit\u00e9 inf\u00e9rieure formul\u00e9es avec une faible teneur en TiO2<\/sub>\u00a0et une teneur \u00e9lev\u00e9e en diluants.<\/p>\n

Les peintures formul\u00e9es avec une forte teneur en pigments TiO2<\/sub>\u00a0ont la plus grande opacit\u00e9. Cela signifie que moins de couches de peinture sont n\u00e9cessaires pour obtenir la m\u00eame couverture. L\u2019utilisation de pigments TiO2<\/sub>\u00a0dans les peintures contribue \u00e9galement \u00e0 les rendre plus durables, ce qui permet de prolonger leur dur\u00e9e de vie.<\/p>\n

L\u2019utilisation de peintures \u00e0 haute opacit\u00e9 et durabilit\u00e9 pour d\u00e9corer un produit permet de r\u00e9duire le besoin de red\u00e9coration pendant la dur\u00e9e de vie du produit, ce qui contribue \u00e0 r\u00e9duire son empreinte environnementale globale.<\/p>\n

Le graphique montre que les peintures \u00e0 forte teneur en TiO2<\/sub>, qui conf\u00e8rent une grande opacit\u00e9 et une longue durabilit\u00e9, ont un PEF total inf\u00e9rieur \u00e0 celui des peintures \u00e0 faible teneur en TiO2<\/sub>.<\/p>\n
