In the past decades, the demand for concrete production has been increasing along with the consumption of natural aggregates. The process requires large amounts of materials that significantly contribute to the global warming and environmental impacts. This study deals with the life-cycle assessment (LCA) of concrete production process. Concrete mixtures prepared with construction and demolition waste (CDW) at different percentages (10%, 40%, 80%, and 100%) are investigated to compare the environmental and energy impacts related to their production with mixtures made of natural aggregates. In order to perform the LCA analysis, SimaPro© software is used with the life-cycle impact assessment (LCIA) method Eco Indicator 99. The proposed model analyses 24 recovery possible scenarios including total landfill and 85% of recycled materials with a distance from the recycling site of 30, 50, 60, and 150 km. The outcomes highlight the benefits derived by mixtures with CDW in terms of emission and environmental impact.

Abstract

In the past decades, the demand for concrete production has been increasing along with the consumption of natural aggregates. The process requires large amounts of materials that significantly contribute to the global warming and environmental impacts. This study deals with the life-cycle assessment (LCA) of concrete production process. Concrete mixtures prepared with construction and demolition waste (CDW) at different percentages (10%, 40%, 80%, and 100%) are investigated to compare the environmental and energy impacts related to their production with mixtures made of natural aggregates. In order to perform the LCA analysis, SimaPro© software is used with the life-cycle impact assessment (LCIA) method Eco Indicator 99. The proposed model analyses 24 recovery possible scenarios including total landfill and 85% of recycled materials with a distance from the recycling site of 30, 50, 60, and 150 km. The outcomes highlight the benefits derived by mixtures with CDW in terms of emission and environmental impact.
