Rubber (Hevea brasiliensis) is a crop widely grown in the Magdalena Medio region in Colombia. To obtain natural rubber, coagulants are used to solidify latex, being formic acid being the most used. However, coagulating substances have consequences in those who manipulate them and in the environment. In the present work, two extraction methods, one conventional (use of formic acid) and the other non-conventional (use of citric acid), were compared. Formic acid stood out for its speed, although it is more expensive than citric acid. The two methods generated sheets of similar elasticity. Citric acid, on the other hand, produced better results in elasticity and environmental impact; its use is recommended for the extraction of latex, for the Magdalena Medio region.
