3 Master X-Seed 150 Created with One Click LCA PRODUCT AND MANUFACTURER ABOUT THE MANUFACTURER The Master Builders Solutions brand brings all of our expertise together to create chemical solutions for new construction, maintenance, repair and renovation of structures. Master Builders Solutions is built on the experience gained from more than a century in the construction industry. The know-how and experience of a global community of construction experts form the core of Master Builders Solutions. We combine the right elements from our portfolio to solve your specific construction challenges. We collaborate across areas of expertise and regions and draw on the experience gained from countless construction projects worldwide. We leverage global technologies, as well as our in-depth knowledge of local building needs, to develop innovations that help make you more successful and drive sustainable construction. The comprehensive portfolio under the Master Builders Solutions brand encompasses concrete admixtures, cement additives, solutions for underground construction, waterproofing solutions, sealants, concrete repair & protection solutions, performance grouts, performance flooring and solutions for on- and offshore wind energy. PRODUCT DESCRIPTION Master X-Seed admixtures are hardening accelerators that boost the hydration process of early age cement. Master X-Seed 150 is added to concrete in order to accelerate the strength development of the concrete mix across all temperature ranges. Master X-Seed consists of synthetically produced crystalline particles suspended in aqueous solution. Master X-Seed is introduced in small amounts (0.5-5 % by mass of the cement content) to concrete in order to accelerate the hardening process. Master X-Seed 150 is optimized for all kind of concretes, especially for structural precast and pre-stressed elements as well as ready-mix concrete.

4 Master X-Seed 150 Created with One Click LCA PRODUCT LIFE-CYCLE SYSTEM BOUNDARY This EPD covers the life-cycle modules listed in the following table. Product stage Assembly stage Use stage End of life stage Beyond the system boundaries A1 A2 A3 A4 A5 B1 B2 B3 B4 B5 B6 B7 C1 C2 C3 C4 D x x x MND x MND MND MND MND MND MND MND x x MNR x x Raw materials Transport Manufacturing Transport Assembly Use Maintenance Repair Replacement Refurbishment Operational energy use Operational water use Deconstr./demol. Transport Waste processing Disposal Reuse Recovery Recycling Modules not declared = MND. Modules not relevant = MNR. MANUFACTURING AND PACKAGING (A1-A3) The environmental impacts considered for the product stage cover the manufacturing of raw materials used in the production as well as packaging materials and other ancillary materials. Also, fuels used by machines, and handling of waste formed in the production processes at the manufacturing facilities are included in this stage. The study also considers the material losses occurring during the manufacturing processes as well as losses during electricity transmission. Master X-Seed hardening accelerators are delivered as aqueous solutions in intermediate bulk containers (IBC) with 1140 kg product. For larger applications the product is delivered in bulk by tank trucks. The IBCs consist of plastic containers (typically HDPE) surrounded by a metal cage (typically steel) supported by an integrated plastic pallet (typically HDPE). Empty containers can be reused or recycled. TRANSPORT AND INSTALLATION (A4-A5) Transportation impacts occurred from final products delivery to the batching plant (A4) are not considered. During concrete manufacture, hardening accelerators are usually added along with the mixing water. Health and safety measures (eye protection, hand protection, possibly respiratory equipment and body protection) are to be taken and consistently adhered to in accordance with the information on the safety data sheet and conditions on site. This scenario is not considered in the LCA for module A5. The treatment of packaging waste (IBC) is covered in the A5 module. PRODUCT USE AND MAINTENANCE (B1-B7) This EPD does not cover the use phase. Air, soil, and water impacts during the use phase have not been studied. PRODUCT END OF LIFE (C1-C4, D) The building deconstruction (demolition process) takes place in C1 module which considers energy for dismantling, particulate matter emissions from dismantling and handling. After the demolition, the admixture is transported to the end-of-life processing (C2 module) where all the impacts related to the transport processes are considered. For precautionary principle and as worst-case scenario, disposal is the only end of life scenario considered. This is modelled by landfill process (module C4) where admixtures end their life cycle.

6 Master X-Seed 150 Created with One Click LCA LIFE-CYCLE ASSESSMENT CUT-OFF CRITERIA The study does not exclude any modules or processes which are stated mandatory in the reference standard and the applied PCR. The study does not exclude any hazardous materials or substances. The study includes all major raw material and energy consumption. All inputs and outputs of the unit processes, for which data is available for, are included in the calculation. There is no neglected unit process more than 1% of total mass or energy flows. The module specific total neglected input and output flows also do not exceed 5% of energy usage or mass. No cut-off was applied in the LCA calculation. All raw materials used were taken into consideration. Manufacture of machinery, buildings, and other infrastructure was not included in the LCA. ALLOCATION, ESTIMATES AND ASSUMPTIONS Allocation is required if some material, energy, and waste data cannot be measured separately for the product under investigation. In this study, as per the reference standard, allocation is conducted in the following order; 1. Allocation should be avoided. 2. Allocation should be based on physical properties (e.g., mass, volume) when the difference in revenue is small. 3. Allocation should be based on economic values. All inputs of materials and utilities for production of Master X-Seed 150 were considered. Packaging: typical intermediate bulk containers (IBC) were assumed, consisting of 20 kg steel cages, 21 kg HDPE integrated pallet and 15 kg HDPE "bottle" (the holding volume) containing a total of 1140 kg of Master X-Seed product. Furthermore, it was assumed that the bottle is not reused; for the steel cage and integrated HDPE pallet 10 use cycles were assumed. The production of Master X-Seed 150 does not involve any co-products. Therefore, no allocation was necessary. Allocation used in environmental data sources is aligned with the above. AVERAGES AND VARIABILITY This EPD is product and factory specific and does not contain average calculations. LCA SOFTWARE AND BIBLIOGRAPHY This EPD has been created using One Click LCA EPD Generator. The LCA and EPD have been prepared according to the reference standards and ISO 14040/14044. Ecoinvent and One Click LCA databases were used as sources of environmental data.
