Product description
Adfil Microfibers are used as secondary reinforcement in concrete matrices and is added in a rate of 0.5-1 kg/m³ of concrete depending on the application. Typical application areas are foundations, floor slabs and precast concrete elements. The construction fibers are embedded in the concrete for the entire lifetime of the concrete structure.
Products included:
Adfil®Sinta M2219, F19, F38, M3019, FDS2219
Interpretation
Polypropylene production is the dominant contributor to the global warming potential (GWP), due to its crude‑oil‑based production and associated carbon‑intensive processes.
In contrast, all other raw materials and manufacturing processes contribute less than 10% to GWP for Adfil Microfibers: Adfil®Sinta. Electricity and packaging drive the modest impacts in Module A3 but remain minor relative to the polypropylene granulate used in Module A1.
Given this imbalance in contribution, Saint-Gobain Construction Chemicals should prioritize supplier collaboration and engagement specifically on polypropylene feedstocks. Improving data quality, pushing for lower‑carbon PP sources, transitioning to alternative chemistries where feasible, or encouraging supplier‑level decarbonization (e.g., renewable energy, energy efficiency, or lower‑impact crude oil inputs) would yield the most meaningful reductions in the product’s overall GWP.
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
