Founder of NatureJAB · Inventor of Microwave Pyrolysis Reactors
About Julian
Julian Alexander Brown is a self-taught inventor and founder of NatureJAB. At age 15, a documentary on ocean plastic sparked a lifelong mission. By 17, while still in high school, he began building his first microwave pyrolysis reactor in his parents’ backyard.
He never attended college. Instead, he iterated through five generations of reactors (Mark I → Mark V), publicly documenting every success and failure. Today he leads one of the most visible grassroots efforts to turn plastic waste into usable fuel.
NatureJAB Mission
NatureJAB develops continuous microwave pyrolysis systems that convert unsorted plastic waste into high-performance fuel called Plastolene® (110-octane).
The technology is designed to be decentralized, solar-powered, and mobile. The latest unit, Mark V, is a continuous-feed, trailer-mounted reactor that runs on solar energy.
Microwave Pyrolysis
Plastic is broken down into hydrocarbon vapor inside a sealed chamber using microwave energy — no combustion inside the reactor.
Plastolene®
110-octane fuel produced from plastic waste. Successfully tested in trucks, muscle cars, and even a Rolls-Royce with zero engine modifications.
Open Science
Builds are documented publicly. Blueprints and progress are shared with the community. Failures are shown, not hidden.

- Supported by JAB Innovations, a registered 501(c)(3) nonprofit
The Bigger Picture
Julian frames the work clearly: the primary goal is not to create more fuel, but to permanently remove plastic from the environment by converting it into something useful. Uncontrolled plastic pollution lasts centuries. Controlled conversion into fuel, he argues, is a measurable improvement.
The project is community-funded and intentionally independent of traditional corporate structures. Every reactor is built with transparency as a core principle.
