Julian Brown, the 21-year-old inventor of Plastoline, has been confirmed safe following a cryptic disappearance that sparked global concern. Brown, celebrated for developing a solar-powered microwave pyrolysis reactor that transforms plastic waste into fuel, vanished from public view after posting a 9 July 2025 Instagram video warning, “keep me in your prayers.” The post triggered speculation across social media, with fans fearing threats linked to his groundbreaking work.
Plastoline’s potential to challenge the $4 trillion global oil industry has drawn both admiration and suspicion. In a March 2025 Bold Journey interview, Brown acknowledged the stakes, stating, “This technology has major implications for all of humanity, only in the right hands.” Online discussions quickly turned to corporate sabotage theories, with one X user posting, “The Government never likes when humans find other ways… they either make them go missing or kill them.”
On 28 July, Julian’s mother Nia Brown told the Daily Mail, “I can confirm Julian is safe, but in the best interest of his security, I’m not able to provide more information.” Her statement, though reassuring, offered little clarity. No law enforcement agencies have confirmed an investigation, and Newsweek reports that neither the FBI nor local police are involved.
The lack of official updates has left a vacuum filled by internet conspiracy theories. A viral X thread noted a white podcaster referring to Brown in the past tense. Others cited a 2024 explosion involving Plastoline that left Brown injured, further fueling fears that he may be targeted.
While there’s no evidence of foul play, Julian Brown’s silence continues to spark concern. Until he reemerges publicly, questions around his safety—and the future of Plastoline—remain unresolved.
