Use advice for data set This LCA covers the Product stage (A1 - A3).
Technical purpose of product or process The cement is manufactured at the Breedon Cement Ireland factory at Kinnegad, Co. Westmeath, Ireland, in accordance with I.S. EN 197-1:2011, Compositions, specifications and conformity criterial for common cements. The main material components of the cement are clinker, ground limestone and gypsum. A small amount of bypass dust is added as well as a chromate-reducing agent to the cement. A grinding aid is also added to assist in the grinding process. The clinker comprises the firing of the following products in the kiln at 1,500OC: limestone, shale, silica clay, silica sand, with small amounts of waste water treatment plant sludge and flue dust. The cement is then bagged in 20kg capacity bags, and supplied to the market via builders merchants. A1 Raw materials supply: The raw materials are limestone, shale, clay, sand for the clinker, and then gypsum, and minor additional constituents (inorganic, comprising no more than 5% of the cement), are added to the clinker to make the final cement product. The CEM II/A-L is then bagged in bags holding 20kg, and then put on the market. A2 Transport: This module covers the impacts of the transport of the raw materials and fuels to the production site. A3 Manufacturing: The main raw materials for clinker, limestone, shale clay and sand, are quarried on site, crushed to smaller sizes and mixed to create a homogenous mix. To this is added crushed shale (clay) and sand. These are then pre-heated before being fed into the cement kiln., where they are burned with a mixture of coal, fuel oil, and alternate fuels: solvents, meat & bonemeal and solid recovered fuel (SRF). The material that emerges from the kiln is clinker. The clinker is then cooled and transported by conveyor belt to the clinker store, and from there to the cement mill, as and when needed. The cement mill grind the clinker and additions as the mill rotates on its horizontal axis. The clinker is inter-ground with additions of limestone and gypsum, and minor additional constituents of by-pass dust, chromate-reducing agents, and a grinding aid (to increase grinding efficiency).
General comment on data set The dataset is representative for the production processes used in 2019. The data Quality Level, according to Table E.1 of EN15804:2012+A2:2019, Annex E, is 'very good' Allocation of electricity types and amounts to the various manufacturing processes has been provided by Breedon Cement Ireland Ltd along with production waste and direct emissions. Allocation of impacts to the products is based on the product composition mass. Flows related to human activities such as employee transport are excluded. The construction of capital assets such as buildings, manufacture of machines and transportation systems are also excluded since the related flows are assumed to be negligible compared to the manufacture of the building material when compared to these systems over a full lifetime of operation. The cut-off criteria of section 6.3.6 of EN15804:2012+A2:2019 have been followed, where 99% of the total energy and materials are included, and the total neglected input flows for the modules reported on in the LCA are less than 5% of the energy usage and mass

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.
