SCS Engineers’ Gomathy Radhakrishna Iyer explains, “The structure of PFAs is a carbon and fluorine bond, and that bond is considered one of the strongest in nature. For industry, Chlorofluorocarbons (CFC), a volatile derivative of methane, ethane, and propane, creates problems globally after they’ve been released. Chlorofluorocarbons are strong greenhouse gases and are also responsible for the destruction of stratospheric ozone.
The most publicized of these compounds are those used as coolants in refrigeration and air conditioners, as propellants in spray cans and similar products, and as solvents for industrial purposes. Chlorofluorocarbons are far less abundant than carbon dioxide in the atmosphere. Still, they are 10,000 times more potent as a greenhouse gas and can remain in the atmosphere for more than 45 to 100 years. Reference
Iyer continues, “PFAS has the same kind of carbon-fluorine bond as CFC but linked to several C-F bonds like a chain making them even more inert and hard to degrade. Breaking this bond is what makes finding effective leachate treatments challenging, but certainly possible.”
It takes a savvy engineer to design safe and effective systems. We’re very proud of our Young Professionals like Gomathy – they’re smart and continue learning with the guidance of our VEPs – very experienced professionals.
