20.500.12556/DiRROS-23873 Potential for improving the environmental sustainability of natural aggregates production (Slovenian case study) The environmental performance of natural aggregates for concrete and road construction, extracted from a dolomite quarry, was investigated. Environmental hotspots were identified, and potential optimization measures to further reduce the environmental footprint were proposed. The natural aggregates extracted from the dolomite quarry have relatively low GWP and a low environmental footprint in general. The GWP of 1 tonne of natural aggregates used in concrete production is 1.13 kg CO2 equiv., while for 1 tonne of aggregates used in road construction, it is 0.97 kg CO2 equiv. The dolomite rock in the quarry in question is tectonically fractured, such that very intensive extraction is not required, taking into account the blasting of the rock and further processing. The use of non-road mobile machinery is already optimized. Additional reductions in environmental impact could be achieved by powering the screening process exclusively with electricity from renewable sources, such as a photovoltaic system. In this context, integrating on-site battery storage systems might present a promising solution for addressing the seasonal mismatch between solar energy generation and processing demands. rock extraction global warming potential environmental impact optimization sensitivity pridobivanje naravnega kamna potencial globalnega segrevanja okoljski odtisi optimizacija občutljivostna analiza true false true MDPI Angleški jezik Slovenski jezik © 2025 by the authors Neznano 2025-10-15 08:10:58 2025-10-15 08:30:00 2025-10-24 03:55:12 0000-00-00 00:00:00 2025 0 0 str. 1-18 iss. 19, [article no.] 10856 Vol. 15 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-10-09 620.1/.2 2076-3417 10.3390/app151910856 253115139 https://doi.org/10.3390/app151910856 0 b7f7c908-a98d-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35411 RAZ_Turk_Janez_2025.pdf RAZ_Turk_Janez_2025.pdf 1 7CCDFF2A11796CCCCDD008892B10878D 21be515bcf08de2afce526bdd12fb99d2a22fcbb0bf518c349bc1be86727bc86 d97404c5-a98f-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35412 Zavod za gradbeništvo Slovenije 0 0 0
