ClearFrom waste to energy - Photocatalytic anaerobic degradation of microplastics to generate hydrogen
Researchers demonstrated that microplastics can serve as a hydrogen source in photocatalytic reactions under anaerobic conditions.

This dual-purpose approach—pollution remediation plus energy recovery—is an intriguing direction for future research if efficiency can be improved.
