Recycled concrete is now used in many different applications and scientific studies have shown that they have performances similar to concretes which use natural gravel [1, 2]. With the aim to evaluate the environmental impacts of recycled concrete, a life cycle impact assessment (LCIA) has been performed and results compared with those of normal This study is the result of a project involving the “Claie-aux-Moines (GCM)” gravel mining company and the Canton of Vaud to determine whether the impacts of transporting materials are significant for three different concrete production processes. Two relevant environmental indicators in building environment showed that the recycled concrete have relatively less impacts than normal concrete. This study also demonstrated that the material origin should be taken into account in the LCIA as transport distances have a non-negligible influence on the impacts. These findings suggest that recycled concrete could be an alternative solution to normal concrete as it contributes to reduce environmental impacts of buildings and preserve natural resources by reusing recycled gravel resources.
