Salmy, The Scientific Dog From The National Autonomous University Of Mexico

Juana Villada Martinez, a food chemist who graduates from the National Autonomous University of Mexico and founder of Grupo Vima inclusionnte AC, along with Salmy, a rescued dog approximately 7 years old, collects cooking oil due to their concern about the excessive use and waste of this oil in the pipes to turn it into soap and crafts to avoid a negative impact on the environment. On this mission, Salmy accompanies several people around the university campus on a green cart designed and built with recycled elements, donated by the industrial designer Hermogenes Gustavo Rojas Coca, who is also a professor at the Faculty of Engineering. Merchants and owners of food stores already know that on Fridays, Salmy, together with the team of scientists, comes to them to receive the collected oil. Since February 2024, Juana Villada and Salmy are assigned a space in the Faculty of Chemistry to transform used cooking oil, a task that is not easy because it must be characterized for its treatment and transformation, as canola, corn, or soybean oils behave differently. This task is carried out with the support of Juan Carlos Ramirez Orejel, an academic technician of the laboratories of the Department of Animal Nutrition and Biochemistry of the Faculty of Veterinary Medicine and Zootechnics of the UNAM. In this place, physicochemical studies are conducted to determine its characteristics such as peroxide indices, acidity, saponification, and density. (Photo by Gerardo Vieyra/NurPhoto)
