UK Average Regen GGBS
Technical purpose of product or process Regen GGBS is produced from granulated blast furnace slag (GBS) by drying and grinding it to a fine powder. The raw material is granulated blast furnace slag (GBS), sourced from the UK and overseas. The GBS is dried and then milled to a fine powder to produce ground, granulated blast furnace slag (GGBS) and transferred to storage silos. GGBS is added at the concrete plants with cement to produce concrete. GGBS is also used to produced blended cements in combination with CEM I cements, CEM II/A-LL and other supplementary cementitious materials (SCMs). Regen GGBS can replace Portland cement in concrete at varying levels, typically ranging from 30% to 85%, with common usage falling between 40% to 50%. This material is known for its durability benefits, offering protection against sulfate and chloride attacks in concrete structures. Additionally, Regen GGBS helps reduce the heat of hydration in concrete, leading to improved long-term durability and reduced risk of cracking. Appearance-wise, Regen GGBS produces a lighter- colored concrete finish compared to Portland cement, enhancing aesthetics and surface. Under normal use, GGBS is not hazardous to the environment. Dust of granulated slag can act as an irritant and cause mechanical irritation to the eyes and respiration system. The GGBS covered by this declaration meets the standard BS EN 15167-1. Performance data for the product is in accordance with the Declaration of Performance with respect to its essential characteristics according to BS EN 15167-1 'Ground granulated blast furnace slag for use in concrete, mortar and grout – Part 1: Definitions, specifications and conformity criteria'. GGBS minimum technical specifications have to answer the criteria listed in EN 197-1: - CaOSiO2MgO > 66 % - (CaOMgO)/SiO2 > 1 - Glass ratio > 66 % Name of ingredient Share of total weight Country of origin Blast furnace slag 100 % various

General comment on data set The Emidat EPD Tool v1.0.0 was used for LCA modeling and calculation. Background data was used from ecoinvent database v3.10. Elementary flows (energy and fuels, ancillary materials and waste) data was collected on production-processlevel. Using the total output of the production process in 2022, elementary flows are assigned to 1 declared unit based on mass. Granulated blast furnace slag (GBS) is a low revenue co-product of the blast furnace iron making process. Economic allocation was used to allocate impacts from the blast furnace process to the GBS, based on the market values of pig iron and GBS in 2022. In addition, the impact of the electrical energy and water used in the granulation process are included in this EPD. All the manufacturing and transport stages from the granulator (at the steelworks) to the factory gate are within the system boundary. This includes all energy, water and emissions from the GBS stockpile, raw material drying and GGBS grinding plant, GGBS storage, loading and dispatch. Environmental impacts of the following processes are considered to be negligible: electricity for quenching, which is a minor part of the energy profile relative to more significant processes (e.g., furnace operations, transportation, or grinding of slag) .

1This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
2The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
