In a world where we’re drowning in plastic (seriously… 500 billion bottles a year?!), four Dubai students just did something that feels straight out of a sci-fi eco-movie — they turned single-use water bottles into usable 3D-printing filament.Yes. Actual filament. From waste. Dubai really stays doing Dubai things.
🌍 Meet the Eco-Squad Changing the Game
Reem Aly, Shriya Vijay, Vishnu Shyju, and Muhammed Sharfuddin — all engineering students at RIT Dubai — basically looked at a pile of empty bottles and said, “What if we make this… useful?”
Under the supervision of Dr. Wael A. Samad, they spent eight months building a full recycling-to-filament production process that schools and universities across the UAE can recreate.
This wasn’t a giant lab.
This wasn’t a million-dirham setup.
This was: normal campus machines + engineering brainpower + zero chill about plastic waste.
♻️ From Trash to Treasure: How They Did It
The team collected 500 bottles from friends, campus bins, and their own backpacks. Then they:
- Washed and dried every single bottle
- Removed labels, caps, rings — the whole shebang
- Shredded the bottles into PET flakes
- Oven-dried the flakes for five hours at 150–160°C (moisture = enemy)
- Fed them into a filament extruder
- Tuned the filament to the perfect 1.75mm diameter
- Spun out real, usable, 3D-printing material
Translation:
12 bottles → 200g flakes → 30m filament strand
You could literally print a small gadget with yesterday’s water bottles.
🧪 But PET Is Difficult… And They Still Did It
PET (the material in most water bottles) has a super narrow processing window. It melts weirdly. It burns easily. It’s not exactly “user friendly.”
But the team optimised everything — extrusion temperatures, printing parameters, flow rates — and even compared their recycled filament to commercial options like PLA and PETG.
Is it perfect? Not yet.
Is it reusable, functional, and sustainable?
Absolutely.
Their results will soon be published in a research paper titled:
Sustainable Filament Production: Recycling Plastic Water Bottles into High-Quality 3D Printing Filaments.
Because yes, Dubai students are out here publishing sustainability breakthroughs like it’s light work.
🇦🇪 A Small Project With Big UAE Energy
With the UAE pushing sustainability hard — from the Green Agenda 2030 to campus-level eco-innovation — this project hits right in the heart of the country’s vision.
Dr. Samad summed it up perfectly:
Students didn’t just recycle plastic…
They turned waste into opportunity.
And honestly?
That’s the kind of energy the planet needs right now.
