Ensuring the Sustainability of Steel Sheet Piles
Environmental Product Declarations and Life Cycle Assessments
Life Cycle Assessment (LCA):
LCA analyzes a product's environmental impact throughout its entire life cycle, from raw material extraction to reuse or recycling.
Environmental Product Declaration (EPD):
An EPD documents environmental impacts based on an LCA, enabling transparent communication by manufacturers. ArcelorMittal’s EPDs are independently verified.
ArcelorMittal Sheet Piling EPDs:
- EcoSheetPilee™ Plus: 100% steel scrap, 100% renewable electricity.
- EcoSheetPilee™: 100% steel scrap.
- Cold-formed sheet piles: 11% steel scrap.
- Hot-rolled sheet piles: 15% steel scrap (pending).
Production Routes:
The secondary production route (electric arc furnace) uses steel scrap and is more environmentally friendly than the primary route (blast furnace). EcoSheetPilee™ products use European steel scrap, reducing emissions and conserving resources. Renewable electricity cuts emissions by 30%. GWP Comparison: The chart shows the Global Warming Potential (GWP) of different production routes based on EPDs.
