Key Achievements
- Structural resin frame: Cellulose-acetate CAFBLO® served as the load-bearing material—rare in architecture, with few global counterparts .
- Seamless printing: A three-week monolithic print overcame thermal expansions and simplified finishing.
- Regulatory approval: Approved as a temporary structure under Expo's building law—Japan’s first resin architecture to pass this step.
- Biodegradability: Incorporates seed paper finishes and CAFBLO®, ensuring the pavilion naturally integrates into the environment post-use .
- Closed-loop recycling: CAFBLO® pellets are recyclable on-site with no quality loss , reducing transport cost and environmental impact.
Materials & Waste Context
- Globally, only ~9% of plastic is recycled; much of the rest is mismanaged .
- MAC aims to process mixed, contaminated plastic waste on-site—turning chaos into building materials and addressing local housing and pollution challenges.
Community & Future Vision
- MAC fosters local engagement—citizens collect and recycle materials, deepening connection with infrastructure. It acknowledges plastics’ dual nature as essential yet harmful, advocating intelligent control rather than avoidance.
- This path extends beyond Pavilion: we envision automated design-to-print systems, resilient local networks using biodegradable materials, and a manufacturing model rooted in circularity, community, and environmental responsibility.
