At the Marathon EXPO held at the Nagoya Women's Marathon 2021 and the Nagoya City Marathon 2021, we offered earth-friendly aroma stones to 500 people who visited our booth and posted it on SNS with hashtags.
This aroma stone, a recyclable and sustainable material made of 100% natural material, is made by ceramics that harden with CO₂. One stone absorbs CO₂ equivalent to about 3.8 500ml bottles. By absorbing and immobilizing CO₂, its emissions are reduced by 70% compared to the conventional manufacturing method.
