The body of the man found in a recycling plant last summer has been identified as Mark Burke from Dun Laoghaire.
Gardai said they have made contact with the family of the 37-year-old, who was only reported missing recently.
His remains were identified through DNA.
An upper leg and lower leg were first located at the Thornton's Recycling facility in Ballyfermot on July 31.
Further body parts were then found following extensive searches of up to 1,000 tonnes of domestic and industrial waste.
After early investigations, it was believed that the victim was "in all probability" a foreign national, due to surgery to his skull he had at some point in his life.
"Mark Burke was reported missing recently," said a Garda spokesman.
"It is not known when he was last seen. The Burke family have been notified and are requesting privacy. A Garda family liaison officer is liaising with the family."
Detectives have made a fresh appeal for information and have urged anyone, particularly those who knew Mark, who may have information regarding his movements during July 2014, to come forward.
"An Garda Siochana would like to take this opportunity to acknowledge the invaluable assistance provided to the investigation team by Thornton’s and their staff, the numerous persons interviewed in this investigation to date, and the professional assistance being afforded to the gardai by forensic and medical professionals," he added.
