Title

The assessment of E-waste management in Macau with LCA method and emergy analysis

English Abstract

At present, e-waste has become one of the fastest growing waste streams in the world. Due to large generation of e-waste and lack of the related laws and treatment facilities, Macau is currently faced with an urgent need to find methods of dealing with e-waste. Therefore, the aim of this study is to learn the status of e-waste, and look for the suitable methods to solve the potential e-waste issues in Macau. Firstly, the questionnaire survey was carried out to investigate the e-waste status by face to face interview in Macau. Through the survey, we investigated the residents‘ behaviors, estimated the generation, and flows of e-waste in the households. In addition, we also analyzed the residents‘ willing to pay (WTP) for recycling the e-waste in Macau to learn the reasons why they don‘t want to pay and the key factors to influence the WTP. Secondly, the whole life cycle of e-products was evaluated to learn the current environmental performance by Life Cycle Assessment (LCA) method. The desktop PC was chosen as the typical e-product, because it can lead to general observations and information that can be valuable for the entire e-product industry. The recycling technologies in mainland China were chosen as the feasible technologies in Macau by comparing with other three recycling technologies, and were adopted in the trial project which was carried out in 2011-2012. In this part, the basic information of trial project was also introduced to learn the detail of e-waste treatment processes. Finally, the trial project and e-waste treatment enterprises in mainland China were evaluated based on the LCA method and Emergy analysis. Through this part, we can understand the economic and environmental performance of e-waste treatment, and at the same time, the comparison of results will help us to learn the regional iii difference of e-waste treatment. Overall, relevant results could provide decision support to enterprise managers and government sectors, so that they could draw up appropriate laws and policies to promote sustainable development of e-waste treatment in Macau.
