A relevant approach to limit virgin materials consumption and waste in the construction industry is to use reclaimed construction products. Their sustainability performance depends on various parameters, including the activities needed to reuse them. Currently, the life cycle sustainability assessment (LCSA) of reclaimed products is conducted following various methods and assumptions, which are not always transparently communicated. There is also limited consideration of other sustainability indicators beyond initial cost and greenhouse gas (GHG) emissions. Therefore, we developed a harmonized Excel-based LCSA framework for evaluating and comparing side-by-side the life cycle environmental (LCA), economic (LCC), and social (S-LCA) impacts of reclaimed and new construction products. This chapter presents the LCSA framework and how it can be applied in practice, with the comparative evaluation of a pavement in Oslo, Norway, with new and reclaimed paving stones. The LCSA framework shows it is possible to harmonize the various assessment methods and expand the scope of product assessment from purely GHG emissions to overall sustainability. The results of the pavement assessment show that reuse can bring lower environmental and social impacts, although it currently costs more to the user. The LCSA framework can be tested by experts in one or more life cycle approaches to guide different actors in the reuse value chain (e.g., product resellers and architects).
