Plastic pollution presents a global challenge. A new non-catalytic pyrolysis technology, grounded in thermodynamics and quantum mechanics, offers an innovative solution. This process transforms plastic waste into powerful fuels, fundamentally shifting our approach to plastic, waste, and energy.

The underlying principle is that all plastic can be repurposed by converting matter and energy. Driven by a passion for social impact, Andoni leads Petgas, a Mexican startup. Petgas is developing this technology and market to convert plastic waste into clean, potent fuels.
