General comment
hydraulic binder not compliant with EN 197-1Scope and type:
The type of this EPD is Cradle-to-Gate A1-A3. All major steps from the extraction of natural
resources to the factory gate are included in the environmental performance of the manufacturing
phase, except those that are not relevant to the environmental performance of the product. The
software SimaPro is used to perform the LCA. The background databases used is EcoInvent 3.6

LCA process diagram according to EN 15804 7.2.1Representativeness:
This EPD is representative for the Ecocem Dunkirk production facility.Calculation rules:
Data quality
Data flows have been modeled as realistically as possible. Data quality assessment is based on the
principle that the primary data used for processes occurring at the production site is selected in the
first instance. Where this is not available, other reference data is selected from appropriate sources.
Data collection period
The dataset is representative for the production processes used in 2021.
Methodology and reproducibility
The process descriptions and quantities in this study are reproducible in accordance to the reference
standards that have been used. The references of all sources, both primary and public sources and
literature, have been documented. In addition, to facilitate the reproducibility of this LCA, a full set of
data records has been generated.
Allocation
Allocation of emissions from steel production to the purchased GBS are in accordance with the
French regulations mentioned in the NF EN 15804+A2/CN and the economic allocation
recommended by the French government DHUP ΠDepartment of Housing, Urban Planning and
Landscape.Scenarios and additional technical information
A1. Raw materials supply
Emissions from the steel production are allocated onto the blast furnace slag in accordance with the
NF EN 15804+A2/CN and the economic allocation recommended by the French government DHUP
ΠDepartment of Housing, Urban Planning and Landscape.
A2. Transport of raw materials to manufacturer
The transportation of the suppliers to Ecocem Dunkirk is done by truck.
A3. Manufacturing
The production consists of grinding and drying of Granulated Blastfurnace Slag GBS and
depending on the end product also mixing with other purchased materials.Declaration of SVHC:
None of the substances contained in the product are listed in the fiCandidate List of Substances of
Very High Concern for authorisationfl, or they do not exceed the threshold with the European
