Families of the 157 Ethiopian Airlines disaster victims are being given bags of scorched earth from the crash site in places of their loved ones' bodies.
Officials have delivered sacks of earth intended for them to bury because the identification process is going to take such a long time.
Two grieving families spoke out about the situation and an Ethiopian government official also confirmed the deliveries of soil.
"The soil came as it became impossible to identify bodies and hand over remains to family members," one family member said.
"We will not rest until we are given the real body or body parts of our loved ones."
Forensic DNA work has begun to identify the remains but it may take six months to establish each of the victims of the crash, who came from 35 different countries.
However, authorities say they will issue death certificates within two weeks.
On Sunday an aircraft hangar in the Ethiopian capital Addis Ababa was filled with the white roses as aviation staff gathered to remember the two pilots and six crew who died in the incident.
Weeping women held slender single stems in their shaking hands.
Banks of the flowers, traditionally used to mark the passing of lives, were placed in front of a row of empty coffins at the ceremony.
"Our deep sorrow cannot bring them back," an Orthodox priest in a traditional black turban and black robes told the crowd.
Multiple agencies are working to establish the cause of the disaster, while Interpol and Blake Emergency Services, hired by Ethiopian Airlines, will work with Ethiopian police and health officials to identify the bodies.
A number of countries have grounded the type of plane, a Boeing 737 Max 8, involved in the crash.
Boeing said it supports the grounding of its planes as a precautionary step but reiterated "full confidence" in their safety.
