In the heart of Zapopan, Mexico, a remarkable breakthrough is taking shape — one that could change how we think about plastic forever. Chemical engineer Sandra Pascoe Ortiz from the University of the Valley of Atemajac has discovered a way to turn cactus juice into a biodegradable plastic alternative. Her work could help solve one of the planet’s biggest environmental challenges: plastic pollution.
The key ingredient behind this innovation is the prickly pear cactus (Opuntia ficus-indica) — a plant deeply rooted in Mexico’s culture and ecosystem. Known for surviving in harsh, dry conditions, this resilient cactus is now showing its potential to help the Earth heal from the damage caused by non-biodegradable plastics.

How the Cactus Plastic Is Made
Ortiz’s process begins by harvesting the pads of the prickly pear cactus and extracting their juice. This green, sticky liquid is naturally rich in sugars and plant gums, which act as organic polymers — the same kind of chemical structures that make traditional plastic strong and flexible.
To create the cactus-based plastic, Ortiz blends the juice with non-toxic natural additives and pours the mixture into molds. Once dried, the result is a thin, flexible film that looks and feels like regular plastic — but behaves completely differently when discarded.
While traditional plastics can take hundreds of years to decompose, Ortiz’s cactus plastic biodegrades within weeks. In soil, it disappears in about two to three months, and in water or compost, it can break down in as little as seven days.

Why This Matters for the Planet
Plastic waste is one of the world’s most pressing environmental issues. Each year, millions of tons of plastic end up in landfills and oceans, harming wildlife and ecosystems. Ortiz’s cactus-based material offers a real alternative — one that’s renewable, sustainable, and even edible.
Unlike petroleum-based plastics, this new material is completely non-toxic, meaning it poses no threat to animals or marine life if it ends up in nature. Even more impressive, the cactus plants used in production regrow quickly after harvest, ensuring a steady and renewable supply without the need for deforestation or chemical fertilizers.
“The cactus is abundant, requires little water, and grows naturally in Mexico,” Ortiz explained in an interview. “It’s a plant that can give us everything we need — even a replacement for plastic.”

The Future of Bioplastics
Although Ortiz’s invention is still in the testing and development phase, it has already attracted international attention. Scientists and environmental organizations see it as a promising step toward reducing global plastic dependency.
If scaled up successfully, cactus-based plastic could be used in packaging, disposable products, and even food containers. Businesses around the world are searching for greener materials, and this innovation from Mexico shows that solutions can come from nature itself — and from the dedication of scientists who think outside the box.
Governments and industries are beginning to support bioplastic research, and Ortiz’s work could inspire more eco-friendly startups in Latin America and beyond. With growing awareness of climate change and pollution, innovations like this are crucial for building a sustainable future.

A Greener Tomorrow Grows in the Desert
Sandra Pascoe Ortiz’s cactus plastic is more than a scientific discovery — it’s a symbol of how creativity and environmental responsibility can work hand in hand. By transforming a humble desert plant into a life-saving material, Ortiz has proven that the answers to global problems might already be growing around us.
In a world drowning in plastic, her invention offers hope — a future where our waste no longer harms the planet, but instead, returns to it naturally.
