Systems and methods for recovery of rare-earth constituents from environmental barrier coatings

A system for rare-earth (RE) element collection and recovery, the system comprising:

• an environmental barrier coating (EBC) fabrication and application system for applying an EBC to an object, the EBC applied as feedstock powder, wherein at least some of the feedstock powder does not deposit on the object and mixes with contaminants;
• and
• a collection and recovery system for chemically extracting the RE elements from the non-deposited powder, the collection and recovery system configured to leach the REs from the non-deposited powder into an acid to form an acid solution, perform an oxalate precipitation on the acid solution to form an RE oxalate hydrate, separate the RE oxalate hydrate from the acid solution, and heat treat the RE oxalate hydrate to form an RE oxide having the RE constituents extracted from the non-deposited powder.
