JULIAN Brown is an inventor and influencer who rose to prominence for creating a device that he claims converts plastic waste into usable fuels.

In July 2025, he made headlines when he vanished from social media, sparking concerns among his followers and climate activism groups.

Julian Brown, a notable figure in the energy sector, went offline after July 9, 2025, following a distressing video he uploaded where he claimed to be in danger.

“Something is happening, keep me in your prayers please. SCREEN RECORD THIS. I don’t know,” Julian wrote alongside the video, which depicted him inside a car.

“I’m certainly under attack. I can’t go into so much detail,” he added.

Days before his last video, Julian shared another alarming message claiming that a “secret helicopter” had found him in the middle of “nowhere”.

Despite his inactivity on social media and troubling final post, Julian’s mother Nia has now debunked the speculation that her son is missing.

On July 28, 2025, Nia informed the Daily Mail: “Julian is safe, but due to security concerns, I can’t share further details.”

Atlanta police also confirmed that the agency is not currently looking for a missing person matching Julian’s information.

The Atlanta Police Department told The U.S. Sun, “We are not currently looking into any missing person case related to that name.”

Who is Julian Brown?

Julian Brown is a 21-year-old scientist from Atlanta with 1.8 million Instagram followers.

He is best known for inventing Plastoline — a device that he claims converts plastic waste into usable fuels such as gasoline, diesel and jet fuel.

The invention employs microwave pyrolysis, a method that heats plastic without oxygen, chemically converting it into fuel.

Julian began developing this technology during high school, teaching himself the necessary science without a formal engineering education.

He has a background in welding, which helped him construct prototypes for Plastoline, using salvaged and homemade parts powered by solar energy.

Julian gained significant public attention and amassed millions of followers by sharing instructional videos and updates on his project.

His mission was to address the global plastic problem by creating the device that transforms plastic waste into fuel.

in November 2024, Julian told Canvas Rebel: “Turning plastic to fuel with reactors has been done before, however, I have been working to innovate utilizing microwaves to turn plastic into fuel.

“To date, there is a very niche application of microwave pyrolysis technology at any industrial and continuous operation scales – that is my goal and mission.

“I am most proud of taking the leap of faith into a innovation that is very dangerous, and doing all of the unseen hard work and labor necessary to further this technology.”

Brown added, “I want everyone to know that we are all capable of solving a world problem, no matter the scale.

“We are all seeds full of potential and amazing fears, but our potential must be watered and fertilized into reality with strong faith, hard work and experience.”

He founded a startup called NatureJab to further develop and scale Plastoline, also launching a GoFundMe campaign to raise $1 million to fund commercial-scale production.

On July 29, 2025, Julian’s ‘Support Solar-Powered Plastic to Fuel Invention’ appeal for donations has so far raised $30,897.
