| Abstract |
Product lifetime extension would contribute to establishing a circular economy and reducing the environmental impacts of mass consumption. Showing the situation of the historical change in the product lifetimes with quantitative data is needed for evaluating the contribution of product lifetime extension. The present study observed the historical change in the actual lifetimes of consumer durables in Japan by three different ways; direct observation; model calculation; simple indicator calculation. The average lifetimes of common consumer durables including home appliances, electronics, and passenger cars have been increasing in Japan over the past few decades. To evaluate the trend of the product lifetimes accurately, product lifetimes need to be observed or estimated based on actual data of discarded, collected, or in-use products. A questionnaire survey that relies on respondents' memory would not provide precise results enough to detect the historical change in the actual product lifetimes. Calculating the ratio of the number of in-use products against the sales would generally be useful to understand the common trend in the product lifetimes over the years when the penetration of the products is saturated. The ratio could also be used as substitutes of the average of the lifetime distribution that is approximated by a statistical distribution function. |
