The smell of death continues to permeate the area, prompting people passing by on a nearby highway to cover their noses. Recovery workers combing through the debris use face masks to block the stench.
Hundreds of people looking for their missing relatives have been waiting by the nearby school where bodies are taken to be identified.
Authorities have sent some of the remains to a Dhaka hospital for DNA testing, BSS reported. Those that remain unidentified are buried.
The industrial disaster here is among the worst ever, ranking behind the 1984 chemical leak in Bhopal, India, which the Indian government said killed more than 15,000 people, many of whom were residents rather than workers.
In his 2008 book "Understanding Global Security," Peter Hough, a senior lecturer in international politics at Middlesex University in Britain, lists just 2,500 deaths in Bhopal, but said Thursday that that number included only fatalities just after the incident.
After Bhopal, he cited 1,549 deaths in a 1942 mining disaster in Hineiko, China; 1,082 deaths in a 1998 oil pipeline fire in Nigeria; and 1,060 in a 1906 mining explosion in Courrieres, France.
Though it is too late for the Bangladesh incident to be included in the soon-to-be-published third edition of his book, the building collapse will doubtless enter history books, he said.
"It's a classic case of a developing country being prepared to cut corners to feed a demand via globalization," he said in a telephone interview. "I'm sure it will be seen alongside other notable disasters. It is already up there in the top five."
