That depends on the type of photo frame. If the wooden photo frame is not painted or treated with varnish, it can be recycled. But the problem arises if it has paint or varnish. It is not possible to recycle wood without removing the external coating. But doing so is not viable more often than not. When it comes to plastic frames, they can or cannot be recyclable. You can check the bottom of the plastic photo frame for the recycling symbol. If there is no symbol, then most likely you will have to throw it in the trash.
