Abstract: Beijing relies on energy-saving supermarkets to carry out "green recycling" of waste home appliances, promotes environmentally friendly recycling of waste products through publicity of green consumption, guides home appliance sellers to carry out green recycling and participate in the construction of reverse logistics systems, and establishes a "green consumption plus green recycling" model with sellers as the main body. During this period, the global unified identification system (GS1 system) coding technology was introduced to design two-dimensional code identification, and the "one machine, one code" traceability management was implemented for the service and process of the recycling of waste household appliances. Based on the construction practice of the "one machine, one code" traceability system in the green recycling of energy-saving supermarkets, summarizes and sorts out the evolution process of the management model, and evaluates the operation of the recycling system based on the "one machine, one code" traceability system effects from the aspects of environmental protection recovery rate and recovery cost. It is concluded that the "one machine, one code" traceability system can help improve the management effect of the waste home appliances recycling system in Beijing. The technical system can be further developed and improved according to the specific conditions of different cities, thereby assisting the transformation of waste home appliances recycling systems in more regions upgrade.
