Analyzing the environmental sustainability of packaging for household appliances: A test case

Nowadays, packaging represents around 35% of the total municipal solid waste yearly generated. This paper aims at analyzing a methodology to support the redesign of a sustainable packaging for the household appliances. The approach considers the environmental impacts related to geometrical parameters and materials. In particular, here the test case is focused on the packaging for kitchen hoods. Through the proposed method, based on the use of virtual prototyping tools, an eco-design approach has been identified to analyze the main environmental impacts. A packaging redesign has been performed to reduce waste and increase the use of the components from the perspective of the circular economy. This study has been performed in accordance with the international standards ISO 14040/14044, by using a Life Cycle Assessment (LCA) from Cradle to Gate. The integration with a CAD tool has been considered to redefine the packaging shape, materials, and internal composition, keeping the same standard requirements (performance, security, etc.). LCA software SimaPro 8.5 has been used to carry out the life cycle assessment, and ReCiPe method has been chosen for the life cycle impact assessment (LCIA). A comparison has been proposed between a traditional packaging for household appliances and a new solution which integrates an interior part in molded pulp. The results show the possibility to cut down the environmental impacts of approximately 15% by a redesign with a molded pulp interior and avoiding EPS structures.
