Recycling rates of waste home appliances in Taiwan.
The objective of this study is to provide a calculation of recycling rates of waste home appliances in Taiwan, for the EPA to amend these rates in order to increase the recycling efficiency. The recycling rate is calculated by a formula according to the statistical results obtained through: (1) an estimation of domestic use of home appliances using time series analysis with multiplicative seasonal ARIMA model, (2) a further estimation of generated waste home appliances based upon the estimated domestic use and the corresponding distribution of lifetime span, and (3) a cost analysis of recycling home appliances based on a sampling survey with stratified systematic sampling conducted among collectors and a survey on five recycling plants of waste home appliances. The suggested recycling rates in this study finally used by the EPA show that all of the recycling rates have increased compared with the rates in previous years. This study also implies that amending the recycling rates may only solve some recycling problems temporarily; however, the recycling system of waste home appliances in Taiwan has to be reformed to increase the recycling efficiency for the long term.
