The deceased, whose identity has not been released, was from the Blanchardstown area near Dublin.
It is understood he was known to police and his remains were identified by fingerprints on the Garda database.
Investigators said he suffered a gruesome death before his body was chopped up and dumped.
Police were called to a wooded area called The Mayne in Clonee on Friday afternoon, after the arm was spotted by a passerby near a stream.
Gardaí said the area was "immediately sealed off for full technical examination".
The remains were removed to the morgue at Our Ladies Hospital in Navan for full forensic examination.
The scene of the discovery was secured overnight and a search operation started on Saturday morning.
Specialist search teams, including the Garda Water Unit and the Garda Dog Unit, were involved.
They found further human remains which were removed to James Connolly Memorial Hospital, Blanchardstown, for a post-mortem.
"Investigators await the results of the post-mortem to determine the nature and direction of this investigation," Gardaí said on Saturday night.
"An Garda Síochána will not be releasing the name of the deceased until all family members have been notified," they added.
"An incident room has been established at Ashbourne Garda Station to investigate all the circumstances surrounding the discovery of this body."
The scene remains sealed off and further searches will be carried out on Sunday.
Police have appealed to anyone who may have witnessed any suspicious or unusual activity involving people or vehicles over the past number of days or weeks, in the Kilbride/The Mayne area, close to the Porterstown Road, Clonee, Co Meath, to come forward with any information.
