Julian Brown, a metro Atlanta native in his early 20s, gained international attention as a climate-focused innovator. A self-taught inventor and certified welder, he spent over five years developing Plastoline, a solar‑powered microwave pyrolysis reactor that transforms plastic waste into usable fuels like gasoline, diesel, and even jet fuel—positioning him as a key figure in sustainable innovation The Times of India+14The Financial Express+14The Economic Times+14.

Under his brand NatureJab, he promoted Plastoline across social media, accumulating approximately 1.7 million Instagram followers and millions of likes on TikTok, using the platforms to highlight his eco‑tech mission and raise funds via a GoFundMe campaign (goal: $1 million; raised: ~$18,208)

On July 9, 2025, Brown shared a deeply unsettling Instagram message. He stated he was dealing with “very, very odd stuff,” asserted he was “certainly under attack”, and urged followers to “keep your eyes open” and “SCREEN RECORD THIS.” He also warned, “I know I don’t have long to live.” That post marked his last known online activity The Times of India+12The Economic Times+12Hindustan Times+12.

Since then, Brown has disappeared from all public platforms. His followers report his absence for nearly two weeks, and speculation has grown intense—some suggesting possible surveillance, black helicopters, or targeting due to the disruptive nature of his invention

🛠️ Plastoline: How It Works

• Employs microwave pyrolysis in oxygen-deprived conditions to decompose plastic into fuel.
• Powered by solar panels installed in Brown’s backyard—designed as an eco-friendly alternative to traditional recycling, with lower carbon emissions The Times of India+12The Economic Times+12The Economic Times+12The Economic Times+1The Economic Times+1.
• Plastoline fuel was reportedly tested at a Washington lab and appeared to burn cleaner than standard diesel, according to technicians
• Brown is recognized as a 776 Foundation Climate Fellow, and through NatureJab he solicited plastic waste and financial support publicly, even sharing his PO Box and CashApp handle for donations and testing materials The Economic Times+6Hindustan Times+6Hindustan Times+6.
• After the final cryptic post, online speculation swirled that major fossil fuel interests might view his technology as a threat. However, no official confirmation from law enforcement or media outlets about his disappearance or whereabouts has surfaced to date

🧠 Why It Matters

Julian Brown’s disappearance raises major concerns—especially given the potential societal and environmental impact of his invention. His story highlights:

• The power of grassroots innovation and independent inventors.
• The vulnerability of activists and disruptors in grassroots tech movements.
• The need for transparency and urgency in safety investigations.
