Why in news
A Yale University doctoral student developed a chemical engineering method to re-engineer PFAS molecules to facilitate their destruction and removal from industrial waste.
Background
Susanna Maisto developed a method to react PFAS with octanol, doubling their molecular size and making them insoluble in water. This process allows for the separation and easier destruction of 'forever chemicals' from industrial waste streams.
Facts for Prelims
- S&TPFAS (Per- and polyfluoroalkyl substances) are known as 'forever chemicals' due to their persistence in the environment.
- S&TThe Yale research involves chemical re-engineering to make PFAS insoluble in water for easier separation.
- FactThe method specifically targets the removal of PFAS from industrial waste streams to prevent environmental contamination.
For Mains
Q. Discuss the environmental and health risks posed by 'forever chemicals' (PFAS) and evaluate the importance of chemical engineering innovations in mitigating industrial pollution.
Dimensions to cover in your answer
- persistence in food chain
- industrial waste management
- technological intervention
- regulatory frameworks
Keywords: forever chemicals · industrial waste · chemical engineering · environmental remediation · bioaccumulation
