Led by Sandra Pascoe Ortiz, a chemical engineering professor at the University of the Valley of Atemajac, scientists at the Universidad del Valle de Atemajac in Guadalajara, have successfully create biodegradable plastic from the juice of the prickly pear cactus.

The researchers trim cactus leaves, and then put them into a juicer and create a bright green liquid. After it’s mixed with other natural materials and processed, it later undergoes a process that transforms the cactus juice into a biodegradable plastic.

Currently it’s being made as prototypes at Oritz’s lab and the process takes 10 days to make. Extensive research is still needed to test the efficiency and to scale up the production of the plastic alternative.

The non-toxic plastic takes one month to biodegrade in soil, and a week in water. The project was supported by a scholarship for graduate students awarded by the National Council of Science and Technology in Mexico.

The bioplastic created from the cactus juice is nontoxic if it’s eaten. “The cactus of this species contains a large amount of sugars and gums that favor the formation of the biopolymer,” says Professor Sandra Pascoe Ortiz, the lead researcher.

Dr. Pascoe Ortiz hopes the bioplastic can replace most single-use plastic products in the world. “I hope the cactus-based plastic will help reduce the impact of solid waste in Mexico and around the world,” stated Pascoe Ortiz.
