General comment The data quality assessment performed during the analysis was based on the Data quality level and
criteria of the UN Environment Global Guidance on LCA database development.
The data quality information has been provided according to the requirements of EN 15941.
ISO 14044 was applied in terms of data collection and quality requirements. The data concerning
the modules A1 (raw material supply), A2 (transportation) and A3 (product manufacturing) were
provided by Tolnatext Bt. and involved all input and output materials to the plant, the consumed
utilities (energy, water) and the distances and means of transport for each input stream. Data
reliability is considered good for energy consumption, material inputs, material outputs, waste
management and very good for transportation. Proxy had to be applied for two processes (Basalt
yarn and module C1 deconstruction)
This LCA report is based on site-specific data from the manufacturer and is representative for the
production for 2024 January – 2024 December (12-month period). The manufacturing location is in
Tolna, Hungary. However, since the components are delivered by external suppliers, their
production processes are modelled using data from the Ecoinvent 3.10 database.
In case of Glass yarn the characterization factor used is of poor quality in means of temporal
representativeness. In case of Chemicals the characterization factor chosen are of very poor quality
in means of temporal representativeness. However, these datasets are highly relevant in terms of
technological representativeness to the materials.
A1 raw material supply, A2 transportation, A3 manufacturing. All used materials, energy, packaging,
and transportation until the end-of-waste state have been included. The information from
transportation A4 is included in the LCA-calculation, but is excluded from the present EPD, because
the A4 module’s GWP (global warming potential) is below 20% of the GWP of modules A1–A3.
Information from B-module has not been calculated nor included in the LCA-calculations. Modules
C1 – C4 have been included. Module D is also included.
