Materials, recyclate & CO₂
Making sustainability measurable
Sustainability only creates real impact when it is measurable. At Interalu, we focus on transparency — from material choices and recycled content to CO₂ emissions across the full life cycle of our climate‑control ceilings. Not to make claims, but to show where impact truly matters.
Long lifespan (>50 years)
Designed for reuse
Measurable CO₂ impact
Certified & verified
Recyclate & circular sourcing
Interalu’s commitment to circularity extends beyond product design. We carefully select suppliers and materials to reduce environmental impact while maintaining performance and quality. Every choice is evaluated across the full life cycle.
- Belgian suppliers where possible, European partners where needed
- Steel containing at least 15% recycled content
- Clips produced with 37% post‑industrial recyclate
- Continuous research into recycled PE‑RT piping

EPD‑based product data
CO₂ emissions & impact
Facts – Local production (Wilrijk, 2021):
- Scope 1 emissions: 88.25 t CO₂ eq
- Scope 2 emissions: 109.60 t CO₂ eq
Facts – Product impact:
- SAPP ceiling: 26.7 kg CO₂ eq/m²
- Easy‑KlimaPlus: 19.7 kg CO₂ eq/m²
Key takeaway
Local production represents only ±2% of the total CO₂ footprint of our climate‑control ceilings.
What is XCarb®?
XCarb® is ArcelorMittal’s global programme for low‑carbon and carbon‑reduced steel production. It focuses on reducing CO₂ emissions in steelmaking — the largest contributor to a ceiling’s environmental footprint.
