Although not dictated by Jewish law, many mohels will request that the baby’s parents bury the foreskin. Human flesh is sacred in Judaism; it is not thrown into the trash. Rather, any detached human flesh is buried: “Ashes to ashes, dust to dust” (paraphrasing Genesis 18:27 and Job 30:19). Some mohels, therefore, will wrap the foreskin in aluminum foil or place it in an envelope and give it to the parents with instructions for them to bury it in the ground. Sephardic Jews have a custom of burying the foreskin under a newly planted tree praying that both the tree and the child will grow tall and strong.
