General comment The values determined to calculate A3 originate from verified Progress LCI inventory data A1 values were prepared considering specific and generic EPDs for the European made glass products . The background data for the secondary inputs come from the Ecoinvent v.3.7 and 3.8 data base.
The alocation rules used for this EPD are based on general ITB PCR A. Production of Bohfalm products is the line process located in Ciele plant (Poland). Allocation was done on product mass basis. The impacts from raw materials extraction and processing are allocated in A1 module of the EPD (including input materials, and energy consumption, transportation, emissions and wastes resulting from the production of glass All company data collected, i.e. all commodities/input and raw materials used, the thermal energy, the electricity consumption and all results of the available emission measurements from the plants were taken into consideration. Minimum 99% of impacts from line production were inventoried and allocated to Bohfalm production. Municipal waste, emissions and waste and energy supply was inventoried for whole production process. Energy supply (gas and was inventoried for whole factory and in a adequate mass based way was allocated to the products assessed. Emissions in the factory are assessed using national KOBiZE emission factors for energy carriers. Data gaps were either filled with comparable data or conservative assumptions, or the data were cut off in compliance with the 1% rule.
99.9 of input materials and 100 % energy consumption (electricity, gas) was inventoried in factory and were included in calculation. In the assessment, all significant parameters from gathered production data are considered, i.e. all material used per formulation, utilized thermal energy and electric power consumption, direct production waste, and available emission measurements. Tires consumption for transport was not taken into account. Ancillary items, precomponents with a percentage share of less than 0.1 % were not included in the calculations. It is assumed that the total sum of omitted processes does not exceed 1 % of all impact categories. In accordance with EN 15804 machines and facilities (capital goods) required for and during production are excluded, as is transportation of employees. Packaging is included.
