Life cycle assessment of cost-optimized buttress earth-retaining walls: A parametric study

In this paper life cycle assessments are carried out on 30 optimized earth-retaining walls of various heights (4e13 m) and involving different permissible soil stresses (0.2, 0.3 and 0.4 MPa) in Spain. Firstly, the environmental impacts considered in the assessment method developed by the Leiden Uni...

Firstly, the environmental impacts considered in the assessment method developed by the Leiden University (CML 2001) are analyzed for each case, demonstrating the influence of the wall height and permissible soil stress. Secondly, this paper evaluates the contribution range of each element to each impact. The elements considered are: concrete, landfill, machinery, formwork, steel, and transport. Moreover, the influence of the wall height on the contribution of each element over the total impact is studied. This paper then provides the impact factors per unit of concrete, steel, and formwork. These values enable designers to quickly evaluate impacts from available measurements. Finally, the influence of steel recycling on the environmental impacts is highlighted. Findings indicate that concrete is the biggest contributor to all impact categories, especially the global warming potential. However, the steel doubles its contribution when the wall heights increase from 4 m to 13 m. Results show that recycling rates affect impacts differently.The authors acknowledge the financial support of the Spanish Ministry of Economy and Competitiveness, along with the FEDER funding (BRIDLIFE Project: BIA2014-56574-R) and from the European Institute of Innovation and Technology under grant agreement no 20140262 Low Carbon Strategy in the Construction Industry (PGA_APED0094_2014-2.1-278_P066-10).
