Product lifetimes are a relevant topic of discussion towards establishing a circular economy, particularly in terms of the reduction of environmental impacts by improving product longevity. Various researchers have developed models to estimate actual lifetimes and have reported case studies for some product categories (e.g. electrical and electronic equipment, and vehicles). However, actual lifetimes may not necessarily meet consumers' expectations. Therefore, an integration of the two perspectives—actual and expected product lifetimes—should prove helpful in optimizing product lifetimes. We proposed different definitions of expected product lifetimes from the consumer perspective and then investigated consumer expectations of the product lifetimes of consumer durables according to these definitions. Several types of EEE were examined as case studies, and questionnaire surveys were conducted. We found that expected lifetimes varied according to the definition used. Expected product lifetimes should be measured by using clearly defined terms to analyse the gaps between actual product lifetimes and consumer expectations.

Third generation photovoltaics (3GPV) which include dye-sensitised solar cells (DSSCs); organic photovoltaics (OPV); and perovskite solar cells, are promising green energy technologies in their infancy which hold the promise of low cost energy generation for the future. At this early stage in development, full lifecycle optimisation taking account of all parts of the product lifecycle is required to maximise the resource efficiency benefits associated with the use of these technologies to create a truly sustainable renewable energy technology. Here we examine the advantages of lifecycle optimisation for 3GPV technologies along with key aspects of design; materials selection; manufacturing processes; likely applications of the technologies; and potential recycling and refurbishment strategies. We identify features which are conducive to circular economy and identify barriers to resource efficiency for these technologies, and suggest some potential solutions and priority areas for future research.
