To answer your question, ferric chloride with copper is difficult if not impossible to recycle. When you neutralize the ferric chloride to precipitate the copper, you also precipitate the iron. The sludge makes it difficult to separate the copper from the iron. There is a company you can contact to get more information. This company does provide recycling of ferric chloride. The companies name is Phibrotech and the contact person is Phil Edelstein. He can be reached at 800-223-0434 or at his e-mail pedelstein@phibrochem.com. You may call him and provide him with the details and they should be able to help you. A third option was suggested as switching the etching solutions to sulfuric acid/hydrogen peroxide. This is recyclable and a company by the name of Onyx Environmental will take the sulfuric acid/hydrogen peroxide. They can be reached 800-255-5092.
