For promoting material circulation by recycling and preventing global warming caused by CO2 emissions simultaneously, it is essential for recycling factories of end-of-life assembly products to economically disassemble and recover the parts/materials with higher CO2 volumes which can save the CO2 emissions comparing to produce the same virgin parts/materials.This paper proposes a disassembly system design with an optimal environmental and economic parts selection which harmonizes a CO2 saving rate and recycling cost using a Life Cycle Inventory (LCI) database. The first stage is to optimize the environmental and economic parts selection by the integer programming with ε constraint, and the second stage is to carry out the disassembly line balancing for minimizing the number of stations.
