Product Description

This EPD covers a next-gen concrete mix designed for ultra-low carbon emissions using:

  • Circular Materials (30% by mass): Replaces a full 30% of the cementitious binder with circular materials—primarily recycled aggregates and ISO certified recycled polypropylene fibres. This diminishes the need for high-carbon cement, utilizing construction waste in compliance with circular economy principles.
  • Eco Elite Cement (70% by mass): A proprietary cementitious binder for 90% fewer CO₂ emissions compared to ordinary Portland cement (CEM I).

Environmental Performance – Potential CO₂ Emission Reduction

Potential CO₂ Savings:

  • 30% circular materials reduces emissions by ~30% for this portion of the binder.
  • Eco Elite Cement (70%) yields a 90% reduction vs. Portland cement.
Example Calculation:

Standard Portland cement: 850 kg CO₂/tonne
Emissions from 70% (if not replaced): 595 kg CO₂
Emissions from 70% Eco Elite (90% less): 59.5 kg CO₂
Emissions from 30% circular (assuming 50% less): 127.5 kg CO₂
Total for binder: 187 kg CO₂
Reduction vs. 100% CEM I: 78%

Reduction Achieved at Scale

For a real project (5.5 m³ foundation):

Traditional concrete emissions: 4,686.62 kg CO₂e Low-carbon concrete emissions: 328.06 kg CO₂e Reduction: 92.99%
CO₂ reduction per 5.5m³ is equivalent to the annual absorption of 430 mature trees.
Potential 4.3 carbon credits earned (value: ~€215 at €50/credit).

Environmental Performance – Global Warming Potential (GWP)

This EPD's life-cycle analysis is based on EN 15804 (cradle-to-gate with end-of-life scenario):

  • Module A1-A3 (Product Stage): Extraction & processing of raw materials, transport to site, and manufacture.
  • Module C (End-of-Life Stage, Option): Demolition, transport, processing for recycling/landfill/disposal.
  • A1-A3: Massive GWP reduction via circular materials and Eco Elite Cement
  • C: Concrete can be designed for reuse or crushed for aggregate recycling, supporting circularity at end of life.
  • Overall: Full LCA pending; estimated GWP as low as 60 kg CO₂e/m³

Verification of Abatement Calculations & Issuance of Certificates

Independent Verification: Third-party assurance of life-cycle abatement results. Example providers include:

  • Bureau Veritas
  • SGS
  • DNV
  • ERM CVS
  • Local Green Building Certification Bodies

Carbon Registry & Certificate Issuance: Verified results may be registered on international platforms for tradable carbon credits:

  • Verra VCS Registry
  • Gold Standard
  • Emerging Regional/National Registries
  • Specialized Carbon Trading Platforms
Note: Choose providers with expertise in EPD/LCA methodologies, ISO 14064, and construction sector materials.

Conclusion

Eco Burial Chambers' Low-Carbon Concrete demonstrates the power of combining circular materials and ultra-low carbon cement to deliver up to 93% CO₂ emissions reduction. Credible EPDs backed by third-party verification and carbon credit registration offer a practical pathway for the construction sector to embrace a low-carbon future and monetize sustainability achievements.
