Plastic elements for the construction sector and industry. Average group - 24 Mix boxes and bags

Harpun plastic elements are high-quality plastic accessories used for leveling, spacing, supporting, and sound reduction in the building sector and industry. They include wedges, flooring wedge systems, adjustment panels, wall brackets, spacers, concrete aids, sound reducers, QuickFix spacers, and terrace supports for the precise installation of floors, windows, doors, and concrete elements, among others. Product description The declared products are manufactured at two production sites in Denmark: Slangerup and Rødding. Data from both production sites have been used for this EPD covering the production in 2024. The declared products represent a weighted average of the two production sites, where the weighting is based on the production volumes in kg in 2024 for each site. This EPD describes the environmental impact for Harpun plastic elements. The EPD covers 187 individual products across 10 product categories: • Wedges (8 products) • Wall brackets (4 products) • Flooring wedge system (15 products) • Sound reducers (10 products) • Adjustment panels (44 products) • QuickFix/QuickFix mini (12 products) • Glass panels (56 products) • Concrete accessories (4 products) • Mix boxes/bags (33 products) • Terrace concept (1 products) The products are grouped into 46 average datasets. EPD Denmark’s rules for grouping have been applied and the averages are based on simple averages. The relationship between individual products, product categories and average groups are presented in the table below. The table also contains information about the weight per sold unit, and the number of pieces in each sold unit, which can be used to convert the impacts of the declared unit (1 kg product) to the impacts per sold unit or per single piece.

Energy modelling principles Foreground system: In A3, the product is produced using a combination of power from Harpun’s own solar installations and a residual mix from the grid. Information about the energy mix in the foreground system: Energy mix EF Unit Residual grid mix 0,703 kg CO2e/kWh Own solar installation 0,031 kg CO2e/kWh Background system: Upstream processes are modelled using consumption/grid mix. Downstream processes are modelled using consumption/grid mix. System boundary This EPD is based on an LCA with the following system boundary: cradle-to-gate with options, modules C1-C4 and D. 100 weight-% has been accounted for. The general rules for the exclusion of inputs and outputs follows the requirements in EN 15804, 6.3.5, where the total of neglected input flows per module shall be a maximum of 5 % of energy usage and mass and 1 % of energy usage and mass for unit processes. In practice, no known processes have been cut-off in the LCA model.
