Researchers at the University of Cambridge have created a new green chemistry process that transforms difficult-to-recycle plastics into clean hydrogen fuel and valuable industrial chemicals. The method uses solar energy together with sulfuric acid recovered from old car batteries, creating a more sustainable recycling system.
The process focuses on condensation plastics such as PET, commonly used in food and drink packaging. Scientists developed a one-pot reaction system that both breaks down plastic waste and produces hydrogen in a single step. This approach could significantly reduce waste while generating clean energy at the same time.
A major innovation is the use of recycled battery acid instead of newly produced chemicals. Researchers also designed a molybdenum-based catalyst that remains stable under acidic conditions and works efficiently with sunlight. The system can additionally support chemical reactions important for pharmaceutical manufacturing, further improving its industrial value.
Scientists believe the technology could contribute to a circular economy by reducing both plastic and battery waste while supporting sustainable hydrogen production. Although more testing is needed before large-scale industrial use, the discovery is considered an important advancement in green chemistry and renewable energy research.
