Plastic Waste to Hydrogen Fuel

May 17 , 2026 14 hrs 0 min 16 0
  • Scientists developed new methods to convert plastic waste into hydrogen fuel using sunlight through a process called photoreforming.
  • Photoreforming is a photocatalytic process where sunlight and catalysts break down plastics to produce hydrogen and industrial chemicals.
  • Researchers from the University of Cambridge and the University of Adelaide developed systems using plastic waste, solar energy, and safe catalysts for clean fuel production.
  • The process can convert plastics like polyethylene and polypropylene into hydrogen, syngas, acetic acid, and liquid fuels.
  • Hydrogen is an important clean fuel used in industries such as refining and ammonia production.
  • Global plastic production is more than 400 million tonnes annually, but less than 10% to 18% of plastic waste is recycled.
