• Abstract

    All aspects of a product or system's life cycle, from raw materials to disposal extraction, can be evaluated for their effects on the environment using the Life Cycle Analysis (LCA) technique. When considering the environmental impact of recyclable aggregate, such as recycled concrete or asphalt, LCA provides valuable insights into the potential benefits and drawbacks. This study used ISO 14044 (LCA) to assess the effects of matter cleared during recycled aggregate (RA) manufacturing (dry/wet) on acidification potential (AP), ozone depletion potential (ODP), global warming potential (GWP), biotic resource depletion potential (ADP), and eutrophication potential (EP). When contrast to recycled aggregate (dry), wet recycled aggregate had an environmental effect that was up to 16–40% greater. This difference was mostly due to the energy consumption of impact crushers during the construction of wet RA. The use of RA was shown to have an environmental impact that was up to double as large as of utilizing natural aggregate (NA), partly because the manufacture of NA was more energy-efficient and simpler. The usage of RA is made from leftover building waste, whereas the utilization of NA depletes natural resources and results in an ADP that is roughly 20 times greater. When compared to artificial “light-weight aggregate (LWA)” although higher than “slag aggregate (SA)”, RA GWP was less in the life cycle effects evaluation.
