General comment
The dataset is representative for the production processes used in 2019. The data Quality Level, according to Table E.1 of N15804:2012+A2:2019, Annex E, is 'very good'. Allocation of electricity types and amounts to the various manufacturing processes has been provided by Cemcor 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.

Technical purpose
The cement is manufactured at the Cemcor cement factory at Cookstown, Co. Tyrone, Northern Ireland, in accordance with B.S. EN 197-1:2011, Compositions, specifications and conformity criteria 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 1,500°C: limestone, shale, flue dust, gypsum with small amounts of iron oxide. A1. Raw materials supply The main raw materials for the clinker are limestone and shale. The main raw materials for the cements are clinker, finely ground limestone, gypsum, and minor additional constituents (inorganic, comprising no more than 5% of the cement). 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 and shale are quarried on site, crushed to smaller sizes and mixed to create a homogenous mix. 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. 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, for grinding to the final cement, with other constituents. The cement mill grinds the clinker and additions as the mill rotates on its horizontal axis. The clinker is inter-ground with the limestone and gypsum additions, and other minor additional constituents, chromate-reducing agents, and a grinding aid (to increase grinding efficiency).
