Abstract: The transaction volume of cosmetics is surging, as e-commerce advances rapidly in the context of the Internet and big data, resulting in a large amount of packaging waste that is difficult to recycle. To address the contradictory issues between the high cost of recycling and processing and the low recycling value in the plastic recycling and processing system for cosmetic bottles, reducing the cost of recycling and processing to within target cost range, and improving recycling efficiency to promote the recycling of cosmetics bottles, this paper applies the first creating method to the design idea generation of a plastic recycling and processing system for cosmetics bottles. We first analyzed the unmet needs of the recycling party, established an Extenics model of the contradictory problem, and determined the functional affair-element, the property characteristic-element and the substantial characteristic-element of the recycling system. We then performed extensible analysis and extension transformation on the conjugate part, obtained multiple schemes, judged whether the contradictory problem was solved or not, and used the dependent function of superiority evaluation method to derive the optimal creativity and deepen it. Using the superiority evaluation method, it was calculated that creativity S₃ has the highest degree of superiority, the actual cost of recycling and processing was lower than the target cost after the enterprise assessment, and the contradiction problem was solvedand the creativity has been adopted by the enterprise. Finally, we verify the validity of the application of the first creating method in the design of plastic recycling and processing system for cosmetic bottles.
