In order to unlock this Trophy, you must commit suicide by detonating a Recycler Charge at your feet.
This can be achieved as soon as you obtain a charge. Simply find a corner, or if possible a small room without much furniture or any objects and throw a Recycler Charge into the corner, aiming to get as close as possible to the detonation. For complete certainty that this worked, aim to be killed by the detonation.
Once you have been completely converted into organic materials you will have met the requirements, unlocking the Trophy.
