This paper proposes a design support method for increasing the recyclability of electrical and electronic products. The method estimates the recyclability rate and the disassembly time of a product based on its material composition and end-of-life scenario. Sensitivity analysis is conducted on the recyclability rate in order to quantify the impact of design changes in the product’s material composition, mass of components, and end-of-life treatment processes. For the feasibility check of the design changes, we introduce a structural model of the product, which represents the geometric constraints among components to assess their disassemblability. As a case study, the recyclability of a LCD TV with an end-of-life scenario in Europe was evaluated and sensitivity analysis on the TV generated design alternatives that increase the recyclability rate while keeping the disassembly time of the original design.
