| Abstract |
In recent years, waste electric and electronic equipment (WEEE) pollution problem has caused public concern widely in the world. In China, huge numbers of appliances are sold and discarded each year. It is difficult to carry out reliable estimation of WEEE output using the existing models due to the limited data available in many countries, especially in large developing countries. In order to plan, manage and use WEEE in a sustainable way, accurate forecasting of WEEE generation plays a key role. Based on the quantity of household ownership of appliances in China, several GM (1,1) gray theory models were set up to predict the quantity of household ownership appliances in China. The results indicate that more and more WEEE will be produced. By 2031, the quantity of WEEE will reach 516 million sets, or 13 million tons. By means of the combination of gray relation analyses (GRA) in this research, it was discovered that the realty business has high correlation with Chinese household ownership of appliances. In order to solve the WEEE collection problem, in this paper, it is suggested that the Chinese government issue a kind of WEEE voucher. If the voucher is used successfully in WEEE recycling, it will not only promote a standard recycling system for WEEE, but also can accelerate the extended producer responsibility (EPR) policy implementation in China.
