The iconic Great Circle structure from Expo 2025 in Osaka, initially set to be demolished and used for firewood, will instead be repurposed as construction material in two Japanese cities.
The Great Circle, designed by Japanese architect Sou Fujimoto, was unveiled as the largest wooden structure in the world at Expo 2025 in Osaka, encompassing an area of around 60,000 square meters. Initially, there were plans to demolish this impressive structure and convert it into wood chips for fuel. However, after public outcry and discussions about sustainability, stakeholders decided to reuse the wood from the Great Circle. The recycled material will now be utilized in construction projects in two separate cities in Japan.
The decision to repurpose the wood is significant not only for environmental reasons but also as a reflection of contemporary architectural practices that stress sustainability. The design of the Great Circle emphasized eco-friendliness and economic balance, utilizing various types of local timber such as cedar and cypress sourced from renewable resources to limit the carbon footprint. Returning the used material to the construction cycle highlights a growing awareness of resource conservation.
The transformation of what was once considered waste into valuable construction material sets a precedent for future projects. It demonstrates an evolving mindset where the lifecycle of architectural materials is increasingly scrutinized, ensuring that magnificent creations like the Great Circle contribute positively to their environments both during and after their initial use.
