Glued in batteries can be replaced, and frequently are, and if nothing else refurbishing companies exist. Refurbishing fails however if there isn't any software support for the hardware, and that's what causes a phone to become e-waste. The old school swappable batteries had batteries that died in negligible time and had to be discarded regularly, mechanical failure on the mounting bracket/clips to support the battery swap on the other hand send the device to the trash because they can't be fixed.
