1" Qual-Pex+ 'Easy Lay' pipe

Data quality: The data collection took place in 2024. Data flows have been modelled as realistically as possible. The data quality assessment is based on the principle that the primary data used for materials and processes occurring at the production site is selected in the first instance. Where this is not available, other reference data is selected from appropriate sources. The following five criteria have been assessed for all generic datasets used in this LCA study: • Time-related coverage: All datasets are from Ecoinvent 3.9.1 (2021), ensuring data is less than 5 years old. • Geographical coverage: European datasets (RER) were prioritized to match the primary supply chain. Where unavailable, global data (GLO) was selected as the best alternative. • Technological coverage: Each dataset reflects the most typical technology available in the market during the dataset's reference period. • Completeness: All datasets include full upstream and downstream process chains to ensure completeness. • Uncertainty: Ecoinvent datasets include inherent uncertainty values, with precision levels averaging ±5% for primary material processes. Allocation: In accordance with EN 15804+A2, Section 6.4.3.3, the following allocation principles have been applied in this study: • Waste allocation: Any waste generated during the production process was allocated based on mass. For instance, production waste such as pipe cuttings and off-spec material was modelled as waste output. • Recycling and secondary material Use: Recycling processes have been modelled using a conservative approach. Recycled content is accounted for within the material production stages, while recycling credits for recovered material at the end of the pipe’s life are included in Module D. These allocation rules ensure compliance with EN 15804+A2 guidelines and provide a fair representation of environmental impacts throughout the product’s life cycle. Cut-off criteria: Exclusions The following elements are excluded from the scope of this LCA study in accordance with EN 15804+A2: • Commuting of employees to and from the production site • Machinery used within the facility (e.g., forklifts, maintenance equipment) • Office-related activities such as IT equipment, administrative energy consumption, and staff facilities • Capital goods and infrastructure (e.g., building construction and maintenance of the factory) These exclusions are considered immaterial and are unlikely to significantly affect the overall results.
