Samsung Electronics has established three principles to ensure that Galaxy Note 7 devices are recycled and processed in an environmentally-friendly manner.
First, devices shall be considered to be used as refurbished phones or rental phones where applicable.
Second, salvageable components shall be detached for reuse.
Third, processes such as metals extraction shall be performed using environmentally friendly methods.
Those 2 million+ recalled Note 7 units has to go somewhere and since the only exploding part of the Note 7 is the battery, it makes sense for Samsung to recycle components of the phones and extract precious metals that can be use again.
