Edgar Castro Aguirre

PhD Candidate, Research Assistant

Edgar Castro Aguirre


School of Packaging


Edgar graduated from Electromechanical Engineering in 2009, and then he worked as a packaging designer in Vitro until 2011. He completed his Master’s Degree at the School of Packaging MSU in 2013. During his Masters studies, he designed and constructed a system to assess the aerobic biodegradation of materials under composting conditions; he also worked on a research project evaluating the effect of biodegradation-promoting additives on the biodegradation of PE and PET in different environments. Currently, he is studying the development and the biodegradation of novel bio-based, biodegradable, and compostable materials. Edgar is also doing a specialization in the Environmental Sciences and Policy Program since he considers vital to translate scientific research findings into solutions for the contemporary environmental issues and actions that benefit both the society and the planet.

Research focus:

Edgar is working on a multidisciplinary research project under the direction of Dr. Rafael Auras. His research seeks to understand if the addition of nanoparticles to biodegradable polymers affects their biodegradation rate and inherent biodegradability, and if the presence of nanoparticles affects the microbial population present in the environment. The overall goal of his project is to assist companies and organizations in making sound decisions about whether or not to use bio-nanocomposites as packaging materials with compostability or biodegradation as their intended end-of-life.
