Julian Brown, a 21-year-old self-taught inventor, developed Plastoline, a device that uses solar-powered microwave pyrolysis to convert waste plastic into usable fuel. He quickly gained over 1.7 million followers on social media by sharing his journey under the handle NatureJab. In July 2025, he posted alarming videos claiming he was “under attack,” then suddenly went silent, sparking widespread concern and conspiracy theories. Although no one filed a missing person’s report, his mother later confirmed he was safe. Brown’s inventiveness and mysterious disappearance captured public attention, highlighting both his environmental mission and the challenges independent disruptors often face.
Julian Brown: Career and Early Life
Julian Brown was born on September 1, 2003, in Tennessee. Raised by his mother, Nia Brown, he showed an early passion for innovation and problem-solving, telling his mom at age five that he wanted to “change the world”. In high school, he taught himself welding and began experimenting with microwave pyrolysis to develop his plastic‑to‑fuel conversion system.
Brown did not pursue formal engineering education after graduating from Chapel Hill High School in Georgia. Instead, he used trial-and-error and internet resources to improve a functional prototype of Plastoline, a solar-powered microwave pyrolysis machine that converts plastic waste into jet fuel, diesel, and gasoline. In 2020, he introduced his eco-friendly brand NatureJab. Later, he established Jabaroma, a cruelty-free deodorant company, whose sales helped fund his fuel-tech endeavors.
Julian Brown Net Worth
Julian Brown’s net worth is estimated to be between $100,000 and $500,000. He earns an estimated $1.6 to $2.2 million annually through his online platforms and projects, but much of this income is reinvested into his work. A large portion goes toward developing his inventions like Plastoline, maintaining his workshop, producing content, and funding ongoing experiments. He also covers business, legal, and operational expenses. Instead of focusing on personal profit, Julian channels his earnings back into innovation and environmental solutions. As a result, his net worth remains relatively modest despite his high revenue.
So while Julian earns like a millionaire, his actual wealth is still growing. He’s more of a visionary entrepreneur and inventor than a traditional influencer looking to get rich fast.
Julian Brown: Lifestyle & Personal Interests
Julian is not your typical influencer or inventor. He’s a DIY enthusiast who builds his machines from recycled materials. He created his “Plastoline” device – meant to turn plastic into fuel – using scrap microwaves, solar panels, and parts he salvaged himself. Most of his time is spent experimenting, problem-solving, and learning by doing.
Though private in real life, Julian opened up a lot online. He shared his work regularly through videos, updates, and live builds on TikTok, Instagram, and YouTube, earning millions of followers inspired by his creativity and mission.
Despite his online popularity, Julian remains a private and cautious individual, prioritizing his work and well-being over public attention. His recent withdrawal from social media suggests a deeper commitment to safety and focus, reinforcing that for Julian, it’s never been about the spotlight – it’s always been about the mission.
