I have synthesized a membrane and used for separation CO2/CH4, now I'm going to investigate of productive impact on Environment with Life cycle assessment attitude via SimaPro software, On what basis do we select a appropriate model in LCA software?
Dear Eshagh,
It depends on two things. The first is the environmental impacts that you are interested in. for example, if you want to quantify water use, you need to choose a method that incorporates water consumption (e.g. Bees+). The second is consideration of the methods that have been previously taken by membrane LCA studies. Adopting similar methodologies will help you have a better comparison among your membrane environmental impacts vs other membranes environmental impacts.
Help you find it useful,
Ramin
Dear Eshagh,
Could you clarify what you mean by "model"? Are you talking about the selection of an impact assessment method (then I refer to the answer of Ramin Ghamkhar). Or are you referring to something else (e.g., system model of your database)?
Cheers,
Paul
Hi Eshagh,
Here, you are dealing with a new process. First you have to model your process in a way it describes the functionality you are looking for. For example, you must define the goal and scope of your assessment. For instance, if you are about to claim that the separation method that you have invented, works better than another conventional method, you are about to conduct a comparative LCA analysis. It significantly affects the boundaries and assumptions you will use, and so, the results. Other options would be cradle to grave, cradle to gate, etc. Most of the the time, you don't want to show the total impact of your product on the environment, but, you just wanted to signify the effect of a change.
Simapro, or any other software will help you to conduct your experiment, but modeling, and the goal and scope, stems form the type of results you are looking for. After successful modeling and obtaining LCIA results, you have to think about the impact assessment methods. Responses of the other fellas about choosing the impact assessment methods were perfect.
Good luck!
