This is part of it. Early pretreatment methods. Then some organic matter mainly involves some wood, we may just want to soak, desalinate, clean, and then keep water treatment. Because the specific next step must be after the end of this (archaeological) site, we have time to proceed slowly (processing), and this cycle is also very long.
