General comment The EPD covers products extracted and processed at the Pagiriai Gravel Quarry in Vilnius (Lithuania), which
provided data for the period January - December 2024. The data collection has been done internally and
thoroughly. The data is based on yearly production amounts and extrapolations of measurements on specific
machines and plants. The EPD covers raw material supply, product production and end-of-life in Europe
geographical scale. Aggregate production involves excavating, washing (group 1-2), and crushing (group 3) the
sand and gravel. The site is powered by residual mix energy, additionally diesel for mobile machinery use.
Background data was sourced from the ecoinvent 3.11, and One Click LCA databases. No poor or very poor data
was found during the assessment of relevant data using PEF method (EN 15804:2012+A2:2019, Annex E, only E.2).
The data quality assessment is done in accordance with EN 15941:2024 and is assessed in terms of precision,
completeness, representativeness, consistency, and sources of data. Overall, the data quality can be described as
good. The EN 15804 reference package used is based on EF 3.1.
Allocation is required if some material, energy, and waste data cannot be measured separately for the product
under investigation. In this study, as per EN 15804, 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.
The allocations in the Ecoinvent 3.11 datasets used in this study follow the Ecoinvent system model ‘Allocation,
cut-off, 15804:2012+A2:2019. The methodological choices for allocation for reuse, recycling and recovery have
been set according to the polluter pays principle (PPP). Scenarios included in the LCA are based on realistic
scenarios which are currently in use and are representative for one of the most likely scenario alternatives. The
environmental impacts of capital goods (e.g., production equipment, recycling machinery) and infrastructure (e.g.,
recycling facilities, transportation systems) have not been included in this assessment.
The study does not exclude any modules or processes that are mandatory according to the Standards and PCR. No
hazardous materials or substances are excluded. All major raw materials and energy inputs, as well as emissions
and outputs from the unit processes for which data is available, are fully included in the calculation. In line with
the PCR, the total excluded input and output flows do not exceed 5% of energy use or mass across the life cycle.
