The Mighty Nopal Cactus

Two students from the Mexican university UNAM have won a prize for making a bioplastic straw from mango and the baba (for non-Mexicans this is a type of “slime” similar to that produced when cooking okra) of the nopal cactus.

This cactus is amazing. Apart from being a potential foodstuff of the future it is also capable of producing a non-toxic biodegradable plastic potentially capable of replacing single use plastic bags……

……..and can be made into a powder which can filter toxic metals and bacteria from polluted drinking water.
