Use advice for data set | The EPD covers the product stage analysis A3, A4 + end of life C and D (“cradle to gate” with options). The selected system boundaries comprise the production of input raw materials’ extraction up to the finished product at the factory gate (ready concrete). The product stage contains: Module A1: extraction and processing of raw materials (ash, sand, gravel, additives, water, and cement) and fuels, Module A2: transportation up to factory gate of raw materials and primary fuels, Module A3: concrete production (mixing). Inputs and processes of product system are presented in Figure 1. |
Technical purpose of product or process | Concrete is specified and supplied in accordance with EN 206 with Polish amendment PN-B-06265. Concrete is used for site-mixed structures, precast structures and structural precast products in buildings prefabricated structures and structural prefabricated products in buildings and buildings. The product assessed is a specific 1 m3 of mixed concrete, where the constituent proportions are provided in Table 1 based on average values from 8 plants. Ready-mixed concrete is commonly used in construction for: internal and external walls, roofs, foundations, piles, columns, supports, joists and other elements. More detailed information is available in the respective manufacturer's documentation (e.g. product data sheets available on request). |
General comment on data set | The values determined to calculate A1 (cement) and A3 originate from verified LCI inventory data from cement production plants (ITB-EPD) and 22 concrete production plants. A1 values (raw materials) were prepared considering specific data and Eco invent data for the aggregates and ashes. The allocation rules used for this EPD are based on general ITB PCR A and EN 15804. Each manufacturing plant was subjected to LCI data analysis. The values adopted for the calculations were averaged from 8 plants using a weighted average. As no co-products are produced, the flow of materials and energy and also the associated release of substances and energy into the environment are related exclusively to the concrete mix produced. Cement used is produced in Poland and the weighted average mass of CEM III/A 42,5N-LH/HSR/NA and CEM II A/V 42,5 production was used for allocation. Minimum 99.5% of impacts from the production were allocated to product covered by this declaration. Emissions allocated in cement production are assessed by ITB using EN 15804+A2 (specific EPDs). Calculations for GWP indicator are made considering gross emissions. The indicated gross value includes the CO2 emissions from waste incineration (excluding biomass fraction of fuels). In this assessment, all information gathered from data collection for the production of concrete has been modelled, i.e. all raw materials used, the electrical energy and other fuels used (oil and diesel), use of ancillary materials and all direct production waste. Transport data on input was considered. The machines and facilities (capital goods) required for and during production are excluded, as is transportation of employees. Calculations for GWP indicator are made considering gross emissions. The concrete recipe is based on weighted average data from 8 locations. |
