However, rose essential oil is characterized by low oil yield, a complex purification process, and waste material after extraction that is difficult to handle, thus resulting in high production costs. To address the above problems, this study applies TRIZ theory for problem-solving, establishes the root causes in the system by using causal analysis, ideal solution analysis, and functional analysis, and analyzes and solves them by using TRIZ tools such as contradiction matrix, physical contradiction, object-field model, and effect knowledge base, and ultimately arrives at 16 solutions. The above solutions were evaluated for cost and feasibility, and finally, 10 feasible solutions were identified, and a new process route for the extraction of essential oil from Damascus rose with low cost and high waste utilization was further developed and implemented in the project. In the improved new extraction process, the oil-water secondary separation system is designed, the reverse osmosis concentration of pure dew + concentrated pure dew re-evaporation process is introduced, the oil-water separation technology is improved, the essential oils in the pure dew are further extracted, and the post-extraction wastes are made into organic fertilizer, rose soap, and so on, thus improving the yield of the rose essential oils and the comprehensive utilization rate of the products. According to the statistics of the commissioned project, the new Damascus rose essential oil extraction process designed by applying TRIZ theory makes the extraction rate of rose essential oil increase by more than 100%, and the utilization rate of the waste material reaches more than 95%, which creates high economic benefits and further reduces the harm of the production to the environment, and this study provides technical references for the research on the extraction process of essential oils of plants and comprehensive utilization of the waste material.
