General comment The data are site-specific data for quantities (raw materials, packaging, waste, energy consumption, distances to suppliers/customers). For the site-specific data, the year 2021 was considered. Data collection was easy as the company is ISO 14001 certified. Generic data extracted from databases were selected on the basis of their geographical, technological and temporal representativeness. The data quality analysis, carried out according to Annex E of the EN 15804:2012+A2:2019, showed a data quality of 'Fair' level or higher.
In this work we have allocated between AMPHIBIA 1.6 and 1.3:
- the electricity consumption data of the membrane factory. The membrane factory also contains a production line not related to the production of
AMPHIBIA. To avoid attributing its consumption to AMPHIBIA products, it was estimated by means of power data and hours of use. The allocations between the different AMPHIBIA thicknesses for the energy consumption attributable to them were then made on a mass basis (kg products);
- the waste produced by the production process from the membrane department: raw material and additive waste, EPDM liner (waste from Amphibia) and water/sludge degassing. Waste was allocated on a mass basis (kg produced) for raw material waste and degassing. On the other hand, EPDM sheaths were allocated on a kg basis (waste). Similar allocation was then replicated for waste transport and end-of-life disposal;
- The amount of waste common to the two processes related to packaging (waste pots, reels, sacks), allocated on a mass basis (kg produced). Similar allocation was, consequently, replicated for the waste transport and end-of-life disposal;
- The amount of ink for printing the AMPHIBIA surface and the solvent used for the cleaning of the printer, allocated on the basis of the m2 products.
Within the Ponzano site, there is also another production department (powder and resin department). With this department the following consumptions are in common:
- Warehouse electricity: allocated on the basis of quantities produced (kg, not considering waste because it is not stored in the warehouse). The warehouse shares the meter with the offices the meter. In order to extrapolate the energy consumption only of the warehouse, an energy analysis was carried out to estimate the consumption of the electricity vector on the basis of the energy uses (lights, forklifts, etc.) present there.
The cut-off criteria are 1 per cent of the renewable and non-renewable primary energy utilisation and 1 per cent of the total mass input of a unit process. The total input flows disregarded per module, e.g. for modules A1-A3, A4-A5, B1-B5, B6-B7, C1-C4 and module D must be a maximum of 5% of energy and mass utilisation.
A cut-off (<1% by mass) was made regarding:
- Instruction sheet inserted in the packaging
- Label attached to the packaging
The cut -off for the process unit 'Packaging' was 0.25% for AMPHIBIA 1.6 and 0.24% for AMPHIBIA 1.3, and for both products <5% for module A3.
