Newer non-stick coatings are often made with naturally occurring elements such as silicon and oxygen, rather than PTFE and PFOA. It is important to check labels, though, instead of going with marketing hype.  The precise nature of the coatings is typically proprietary and writing to manufacturers often reveals some dirty little secrets of non-stick cookware. For example, there are some product marketed as PFOA-free but which aren’t PTFE-free; the coating is still PTFE, just applied with a water-based solvent instead of PFOA.  Ecolution, for instance, has a bakeware range that uses their proprietary Free + Clear surface coating made without BPA, PFOA, and PTFE. However, Ecolution also has a cookware range that uses PFOA-free Hydrolon non-stick coating, which appears to still be PTFE-based. For anyone with a pet bird in the house, getting these confused could be deadly.
