Demand for various products has rapidly increased in developing countries due to rapid urbanization, increase in population, and change in lifestyle, which potentially causes a significant amount of waste shortly. It is expected that, because of the rapid increase in wastes, the current capacity of facilities would not sufficiently meet the requirement of proper treatment and recycling, potentially leading to vital environmental pollution. In particular, Motorcycles are used as major transportation means in Vietnam. The average possession of motorcycles per capita is high, approximately 36% as of 2016, and it is expected to continuously increase due to economic growth. Although there are several informal recycling sectors such as “craft village”, hazardous substances are not adequately treated, causing air pollution and soil contamination in the surrounding environment. Therefore, it is of paramount importance to predict the number of wastes of motorcycles in Vietnam. This study assessed the lifespan distribution of motorcycles in Vietnam through questionnaire survey by using the Weibull distribution and predicted the number of motorcycle wastes and metals contained in obsolete motorcycles in Vietnam in 2019-2030. Considering the increase in the number of scrapped motorcycles and the demand for resources induced by motorcycles, the estimated value might assist policymakers in developing the strategy for efficient motorcycle recycling. |
