Yes, but before they are recycled, bus batteries will be used for power storage on site. This “second life” can extend the service life of the battery from 12 years on the bus to perhaps 20 or 25 years. Once the battery is no longer suitable for storage, the battery will be recycled and the component metals reused. This technology exists now but is not in mass use as current EV batteries are lasting much longer than was originally thought. Recently a Tesla Model X exceeded 560,000 km / 350,000 mile on its original battery.
