Research on the Recycling Model of Waste Mobile Phone Based on System Dynamics

Mobile phone replacement is accelerating, the waste of mobile phone will not only cause a lot of waste of resources, after the simple landfill, the heavy metal infiltration into the soil, rivers and groundwater, but also soil and water pollution, bring serious harm to the animals and plants in contact with the soil and water. Efficient and standardized recycling of increasingly used mobile phones has become an urgent social problem to be solved. The emergence and continuous improvement of “Internte plus” recycling mode of used mobile phones make it possible to solve this problem. On the various influence factors of recovery efficiency, and their relations on the basis of the analysis of building “Internte plus” old cell phone recycling model of system dynamics model, using Vensim software to draw causal loop diagram and in view of the old cell phone recycling price, information security and logistics cost effect on the recovery mode efficiency is analyzed. Research shows that information security is the most important factor affecting the efficiency of “Internte plus” waste mobile phone recycling model.
