Research On E-waste Reverse Logistics Network Design Under Low Carbon Policy

With the rapid development of electronic information technology and the frequent updating of electronic products,a lot of discarded electronic products have been produced.The most discarded ones are mobile phones.There are a large number of harmful substances in these discarded electronic products.If harmful substances are directly discharged into the natural environment,it will seriously pollute the natural environment and indirectly harm human health.Reverse logistics refers to the activities of waste products from the consumer end to the original production end,including recycling,sorting,warehousing,testing,reprocessing,secondary sales,secondary manufacturing and harmless treatment,etc.It wil ultimately realize the potential use value of waste products.Nowadays,China has gradually realized the importance of reverse logistics activities for the disposal of electronic waste,and relevant government departments have promulgated a series of relevant laws and regulations in a timely manner,mainly starting from the aspects of economy and policy,further standardizing,perfecting and integrating electronics.However,it is still in the initial stage of building a reverse logistics system.This paper takes the e-waste reverse logistics network as the main content of the research and taking the recycling of discarded mobile phones in the Yangtze River Delta region as a case,combining quantitative and qualitative analysis with cases as a research method.On this basis,we established the reverse logistics recovery network in the context of abandoned e-waste under three low-carbon policies(carbon cap,carbon tax,and carbon trading).the most important of our job is Focusing on the selection of nodes and the impact of the amount of traffic between nodes on the reverse logistics network and establishing a dual-objective network optimization model that considers profit and carbon emissions,then use the LINGO simulation software to solve the cases under three low-carbon policy scenarios.We find that the carbon emissions of the entire reverse logistics network have been reduced and the reduction effect is more significant under the carbon limit policy scenario.Othe than that,we find the profit of the entire reverse logistics network has increased and the increase effect is more significant under the carbon tax policy scenario.Finally we find that the third-party recycling companies operate more flexibly under the carbon trading policy scenario,taking the profit and carbon emissions into accoun,thereby achieving a dynamic balance between the two.Based on this,we can consider the profit and carbon emissions to achieve a dynamic balance between the two.In this paper,we can provide important theoretical and empirical support for the rational use of waste electronic products based on the mathematical model under the constraints of low-carbon policy constructed.This can fully exploit the potential value of waste electronic products,which is of great significance for the recycling of natural resources.First,the reuse of waste electronic products can avoid pollution to the natural environment;Secondly,companies can choose their own carbon emission measures based on their previous carbon emissions;Finally,this paper also provides complementary recommendations for countries to develop low-carbon policies.At last,this paper summarized the relative results and conclusions and proposes the future research direction and research prospects for the shortcomings.
