Key Points:The Japan Expo 2025 Pavilion will highlight cutting-edge technology and cultural exhibits, offering a unique experience for visitors.
- A giant wooden ring design mimicking a living organism.
- Integration of biogas technology to convert waste into energy.
- Interconnected interactive zones reflecting continuous cycles.
- Modular structure designed for post-Expo reuse.
- Use of algae and biodegradable materials in the design.
Design Concept: The Organic Ring and Modular Structure
The Japan Pavilion at Expo 2025 is designed as a massive ring constructed from cross-laminated timber (CLT), creating a semi-transparent facade that reveals internal ecological processes. The circular form symbolizes “infinity,” with recyclable materials enhancing sustainability. Gaps in the facade allow visitors to observe biodegradable energy systems and exhibition spaces, emphasizing transparency and interconnectedness.
Table 1: Key Structural Components
| Element | Description |
|---|---|
| Materials | Recycled CLT wood, organic biodegradable materials. |
| Design | Interlocking ring structure enabling natural light and ventilation. |
| Disassembly | Modular panels easily separable for reuse in future projects. |
Sustainability: Biogas Integration and Clean Energy
The pavilion features a biogas system processing approximately one ton of food waste daily from the Expo site. Electric vehicles transport waste to the pavilion, where organic decomposition generates biogas for energy and water for reuse.
“The system is not just eco-friendly technology but an interactive experience demonstrating waste-to-resource transformation,” according to the design team.
Table 2: Waste Processing Stages
| Stage | Description |
|---|---|
| Collection | Food waste gathered via electric trucks. |
| Fermentation | Organic breakdown to produce biogas. |
| Utilization | Biogas powers electricity and heating for the pavilion. |
Interactive Experience: Zones Reflecting Continuous Cycles
The pavilion is divided into three interconnected zones:
- Algae Zone : Showcases algae in furniture, food, and artworks made from diatomaceous earth.
- Technology Zone : Interactive displays on recycling and biogas systems.
- Art Zone : Dynamic water art on diatomaceous earth canvases, symbolizing renewal.
Post-Expo: Reuse in New Contexts
The modular design allows easy disassembly post-Expo, with materials repurposed for buildings across Japan. This minimizes waste and aligns with circular economy principles.
