A database and characterization of existing lifespan information of electrical and electronic equipment

Lifespan of product is essential information for material flow and stock accounting (MFA/MSA) as well as discussing possible contribution of product lifespan extension to waste prevention and materials/energy savings. There are a number of literatures on actual lifespan distribution of products in our society; however, existing information is not well organized. The authors created a database named LiVES (Lifespan database for Vehicles, Equipment, and Structures) by reviewing existing lifespan data of various types of product including electrical and electronic equipment (EEE). In this study, the overview and characteristics of lifespan data of EEE included in the database was reported.
