Join us online Friday, July 23rd Noon – 1PM ET (Boston time. Here is a time converter).

In the last Collective Learning Meeting (CLM) of the 2020-2021 academic year, WPI System Dynamics will host Cissy Amparo Lavadenz-Vargas ( who will present:

Vermicomposting, an eco-san technology to close the loop in Sanitation for developing countries

Short Description: Vermicomposting is a simple and accessible technology to treat organic waste, usually portrayed as clean technology. Nonetheless, the processes and relations that occur in the system are complex and not completely understood. Studies consider the variables are correlated, but the relations are not seen as a whole system. If all the variables are not controlled properly, vermicomposting produces GHG emissions diminishing its benefits. This research focuses on developing a model with system dynamics to elucidate the dynamics of vermicomposting and identify the main parameters to control or calculate GHG emissions.

Question for the Audience: When publishing a paper in the field of System Dynamics, what is the most recommendable approach CLDs or stock and flows? What are the key points when publishing an article in the area?

Biography: I am an Environmental Engineer, currently a Ph.D. student of Environmental Science and Engineering Major at USTB in Beijing, China. My current research focuses on the sustainability of Ecological Sanitation. I am new to the system Dynamics methodology, and I would like to get more insights from experts and practitioners of System Dynamics.

We will record this presentation.
