PremiAL Wins Circularity Award
From Reuters
LIXIL took the top prize in the Circularity category of the Reuters Global Sustainability Awards 2026, which recognises companies putting recycled material into production at industrial scale. At the centre of the win is PremiAL R100: 100% recycled aluminium that cuts manufacturing CO₂ by around 80% versus virgin-ingot profiles.
A finalist in 2025, PremiAL is now the winner — and LIXIL was also shortlisted for the Business Transformation Award.
“We are incredibly honored to receive this recognition from Reuters.” Satoshi Yoshida, Executive Officer, LIXIL Housing Technology.
