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

摘要

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) [1]. In this study, the overview and characteristics of lifespan data of EEE included in the database was reported.
