Titanium Dioxide Against Vinasse
from Heritage Mezcal Hosted by Chava Periban, Ryan Aycock, Roy Sierra
Vinasse, which are maybe the most offensive byproducts when making mezcal or tequila, can be neutralized in a number of ways. Scientists are always trying to offer more efficient and cost effective options to neutralize this nasty stuff, and one of those experiments was brought to our attention by our brilliant medical correspondent, Ryan Aycock (aka Cocktail MD). The technical specifics of how Titanium Dioxide nanoparticles can neutralize vinasse is not really the main focus of this episode, but we decided to delve into what would happen if this approach were to be adopted by the industry at large. What would all that Titanium Dioxide could possibly mean to the health of those applying it to the vinasse or those in the vicinity of the distilleries? It all may sound very sci-fi and complicated, but this conversation tries to show that every decision has repercussions that may not be incredibly evident right away and that fighting one type of pollution may create other challenges. Finally, this is the full citation of the article mentioned in the episode: Alicia Rodriguez Arreola, Marciano Sanchez Tizapa, Florentina Zurita, Juan Pablo Morán-Lázaro, Rocío Castañeda Valderrama, José Luis Rodríguez-López & Alejandra Carreon-Alvarez (2018) Treatment of tequila vinasse and elimination of phenol by coagulation–flocculation process coupled with heterogeneous photocatalysis using titanium dioxide nanoparticles, Environmental Technology.
