The concrete studied is beShot Rck30 S5 XC2 D05 CEM II 42,5 R. For the evaluation of impact, the declared unit of concrete is 1 m3. The reference period for the collected data is the year 2022. The total amount of concrete made, in the considered period, is 6 m3. According to EN 15804:2012+A2:2019 and EN 15804:2012+A2:2019/AC:2021 the study spans from “cradle to gate with options”, with the modules: A1, A2, A3, B1, B2, B3, B4, B5, B6, B7, C1, C2, C3 and D. Exclusion of input and output data, i.e. “cut off criteria”, is fixed at 1%, in term of mass, energy and environmental relevance. Thus, a process can be neglected if its contribution is minor to 1% of the total mass, primary energy and total impact. However, all processes for which data are available are considered, even though with a contribution minor than 1%. The production of concrete is modelled by primary data collected in Colabeton S.p.A., Serravalle Pistoiese (PT) the production site for the above said considered reference period. Allocation is avoided, whenever possible, by dividing the system into sub-systems. When allocation cannot be avoided, mass allocation is applied. For the modeling of waste, the “Polluter pays principle” is applied.
