3 Master X-Seed 130 Created with One Click LCA PRODUCT AND MANUFACTURER ABOUT THE MANUFACTURER Master Builders Solutions is one of the leading suppliers of concrete admixtures and underground construction solutions worldwide. With over a century of experience in the construction industry, we leverage cutting-edge technologies, a global community of experts at the core of our business, as well as in-depth knowledge of local building needs to provide innovative and sustainable solutions. PRODUCT DESCRIPTION Master X-Seed 130 contains a suspension of crystals consisting of nanoparticles specially designed to accelerate the hydration of the concrete in its early stages (6-16 hours). The product is based on a unique and innovative grain formation technology where the growth of hydrated crystals of calcium silicate is greatly accelerated. Master X-Seed 130 promotes concrete curing at low, normal and even high heat curing temperatures. Unlike the traditional acceleration methods and thanks to the unique mode of action – the practically barrier-free crystal growth of the grains between the cement grains – an early strength development is accelerated while the microstructure of the concrete acquires equivalent or improved properties. Master X-Seed 130 can affect the open time of the concrete. Works very well where the concrete has a lower starting temperature. Master X-Seed 130 has been optimized for all types of concrete, especially for precast concrete elements in which a high early strength development is an important success factor for the manufacturer. Master X-Seed 130 is a relevant alternative to heat curing and especially the highly accelerated hydration means that binders with a lower clinker content can be used.

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 x 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. Concrete admixtures are manufactured by mixing the ingredients (together) in batch mode, and then poured in containers or pumped into the truck tankers. Most of the products is shipped with tanker trucks to customers. According to the 2022 company data, only 10% is shipped using intermediate bulk containers (IBC). The IBC consists of 20 kg steel cages, 21 kg HDPE integrated pallet and 15 kg HDPE "bottle" (the holding volume). IBC contains a total of 1140 kg of Master X-Seed product. It was assumed that the IBC is reused 3 times. TRANSPORT AND INSTALLATION (A4-A5) Transportation impacts occurred from final product delivery to the construction site (A4) is not modelled. During concrete manufacture, concrete admixtures are usually added along with the mixing water or included in premixed concrete. The material loss during installation is therefore 0% for admixtures. Since 10% of the product is shipped in IBC packaging, the treatment of the packaging waste is as well modelled in A5. 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 admixture becomes an inseparable part of the concrete, and therefore it undergoes a similar end of life scenario. The deconstruction of concrete takes place in C1 module which considers energy for dismantling, particulate matter emissions from dismantling and handling. After the demolition, the debris are transported to the end-of-life processing (C2) where all the impacts related to the transport processes are considered. According to the regional data, 52.7% of the waste concrete is treated to be reused as recycled aggregates (C3) and the rest (47.3%) is treated as inert material for landfill (C4). The benefits and loads of recycled aggregates (from C3) as well as benefits and loads of the packaging (IBC) waste (from A5) are modelled and included beyond the system boundary (D).

6 Master X-Seed 130 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. ALLOCATION, ESTIMATES AND ASSUMPTIONS Allocation is required if some material, energy, and waste data cannot be measured separately for the product under investigation. All allocations are done as per the reference standards and the applied PCR. In this study, allocation has been done in the following ways: Data type Allocation Raw materials No allocation Packaging materials Allocated by mass or volume Ancillary materials Not applicable Manufacturing energy and waste Allocated by mass or volume The following assumptions were made: - Transport distance for packaging waste (A5) and concrete waste at the end-of-life (C2) is considered 100 km as the worst-case scenario. - Consumed energy for demolition (C1) is 0.07 MJ / kg [Source: EUR 29123 EN Model for Life Cycle Assessment (LCA) of buildings]. - End-of-life waste processing ratio for Sweden is considered 52.7% as recycling concrete and 47.3% as landfill (C3 and C4) [Source: Bygg- och rivningsavfall from The Swedish Environmental Protection Agency]. - The steel cage of the IBC is produced from 42.4% steel scrap and 57.6% from virgin material [Source: World Steel in Figures from WorldSteel Association]. - Waste processing ratios for HDPE part of the IBC are 34.6% for recycling and reuse as plastic, 42.0% for incineration with 73% efficiency, and 23.4% sanitary landfill (A5) [Sources: Energy Recovery from Waste Incineration—The Importance of Technology Data and System Boundaries on CO2 Emissions by Eriksson O., Finnveden G. (2017)] - Waste processing ratios for steel cage of the IBC are 85% recycling and reuse and 15% landfill [Source: The Global Life Cycle of Stainless Steel].
