Use advice for data set The life cycle analysis (LCA) of the declared products covers: product stage – modules A1-A4, end of life – modules C1-C4 and benefits and loads beyond the system boundary – module D (cradle-to-gate with options) in accordance with EN 15804+A2 and ITB PCR A (v 1.6) . Energy and water consumption, emissions as well as information on generated wastes were inventoried and were included in the calculations. It can be assumed that the total sum of omitted processes does not exceed 5% of all impact categories. In accordance with EN 15804+A2, machines and facilities (capital goods) required for the production as well as transportation of employees were not included in LCA.

General comment The data selected for LCA originate from ITB-LCI questionnaires completed by Comrebars Sp. z o. o. and verified during data audit. No data collected is older than five years and no generic datasets used are older than ten years. The representativeness, completeness, reliability, and consistency is judged as good. The background data for the processes come from the following resources database Ecoinvent v.3.10. Specific (LCI) data quality analysis was a part of the input data verification. The allocation rules used for this EPD are based on general ITB PCR A. Production of the Composite bars is a line process conducted in factory of Comrebars Sp. z o. o. located in Stropkov (Slovakia). Allocation was done on product mass basis. All impacts associated with the extraction and processing of raw materials used for the production of the declared product are allocated in module A1 of the LCA. Impacts from the global line production of Comrebars Sp. z o. o. were inventoried and 100% were allocated to Composite bars production. Water and energy consumption (electricity, natural gas), associated emissions and generated wastes are allocated to module A3. Packaging materials were taken into consideration. Minimum 99.0% input materials and 100% energy consumption (electricity, natural gas) were inventoried in a processing plant and were included in the calculation. In the assessment, all available data from production have been considered, i.e. all raw materials/elements used as per formulation process, utilized thermal energy for heating, and electric power consumption. Thus, material and energy flows contributing less than 1 % of mass or energy have been considered. It can be assumed that the total sum of neglected processes does not exceed 1 % of energy usage and mass per modules A or D. Machines and facilities required during production are neglected. The packaging products (stretch film, pallets, etc.) are included.

Technical purpose GFRP composite bars are the answer to the needs of the construction sector in terms of a successor to reinforcing steel, e.g. beams, slabs. For the production of prefabricated reinforced concrete elements. The bars can be used as poles in gardening and as posts for fences in pastures. ComRebars composite bars are not only cheaper per meter by up to 25% (than carbon steel and by up to 50-60% than galvanized and stainless steel), but also significantly reduce the required thickness of concrete. Other advantages of composite bars over steel bars: they reduce material losses during cutting by 90% compared to steel; - more cost-effective transport, logistics, personnel, speed and ease of installation that does not require as much heavy equipment and maintenance; - due to their durability and non-reactivity, they do not require repair, replacement or renovation in concrete; - composite bars are characterized by 2.5 times higher strength than AIIN steel; - are a durable, long-lasting material, resistant to water, including salt water and other aggressive environments, which is why they are used in ports and water infrastructure, where they easily replace several times more expensive stainless steel; - nine times lighter than steel, increasing transport efficiency many times. Composite bars are resistant to chlorides, acids and chemicals, can be used in acidic and alkaline environments. Due to this, they are great for the construction of sewage and in the aquatic environment. They do not create an obstacle to the penetration of electromagnetic waves. They are an electrical insulator and do not conduct electricity - they can be used in magnetic resonance units in medical centers. composite bars have a low thermal conductivity coefficient ?, they are a thermal insulator. composite bars have more than a hundred times lower thermal conductivity compared to steel bars. Below in Table 1, there are produced diameters of ComRebars composite bars covered by EPD. All additional technical information about the product is available on the manufacturer's website. -
