Life cycle assessment and life cycle costing of an innovative component for refrigeration units

Abstract

Life cycle assessment (LCA) and life cycle costing (LCC) are innovative tools based on an innovative approach allowing to investigate the environmental and economic burdens of a product or service throughout its lifecycle. Although usually carried out individually, their integration in a comprehensive analysis could provide a substantial asset in every kind of decision-making procedures. In this study, the sustainability of a newly developed component for refrigeration units is investigated by applying these two tools in a cradle to grave approach in different scenarios. Results from the LCA show the huge impact associated with the manufacturing process of the kit compared to the transport. However, the use phase environmental analysis showed an environmental payback period always lower than 10 years. Results from the LCC show that the initial investment cost represents the highest share for the final user. Furthermore, favourable discounted payback periods are generally found, leading to net savings above 270,000 ¿ in the case best-case scenario.
