Sustainability must be evaluated across three lifecycle stages:
Paper honeycomb
- Renewable raw material
- Lower manufacturing energy
- Biodegradable potential
Aluminum honeycomb
- High recyclability (~100%)
- Long lifecycle reduces waste frequency
- Energy-intensive production but circular reuse potential
Sustainability interpretation
- Paper → low-carbon production model
- Aluminum → circular economy model
Modern green building systems often value recyclability and lifespan, giving aluminum a strong sustainability position in long-term infrastructure.
