| Abstract In the present study, the software Aspen Plus® was used to analyse two different systems for CO2 recycle in a SFE process for extraction of more polar compounds using ethanol as co-solvent, the most common co-solvent used due to its environment-friendly nature. The extraction process of β-ecdysone from Brazilian ginseng roots was considered as example in the computational simulations. The first CO2 recycle system, named Recycle A, considered the compression of the CO2 separated in the second flash to the recycle pressure assumed at the first flash tank, its cooling to 25 °C and recirculation, while the second recycle system, named Recycle B, considered the cooling and pumping of the CO2 separated in the second flash, its heating to 25 °C and... |

| Many current water planning and management problems are riddled with high levels of complexity, uncertainty, and conflict, so-called “messes” or “wicked problems.” The realization that there is a need to consider a wide variety of values, knowledge, and perspectives in a collaborative decision making process has led to a multitude of new methods and processes being proposed to aid water planning and management, which include participatory forms of modeling, planning, and decision aiding processes. However, despite extensive scientific discussions, scholars have largely been unable to provide satisfactory responses to two pivotal questions: (1) What are the benefits of using participatory approaches?; (2) How exactly... |
