The Hanoitimes - Cast iron slag is still considered solid waste to be treated and buried in Vietnam.
The Vietnam Steel Association and the Vietnam National Cement Association on October 5 in Hanoi jointly organized a workshop on the status of processing and promoting the use of cast iron slag in Vietnam.
Addressing the workshop, Vice President of the Vietnam Steel Association Nguyen Van Sua said that Vietnam’s iron and steel industry has developed rapidly in recent years. Currently, there are ten blast furnaces operated across the country.

He said that cast iron slag is still considered solid waste to be treated and buried in Vietnam. This practice not only has an adverse effect on the environment but also costs and occupies a certain area of land for the treatment of the cast iron slag.
Sua added that in many nations around the world, cast iron slag is considered a resource, and has been studied and widely used in the construction field. Recycling cast iron slag is not only beneficial for the environment but also contributes to the country’s sustainable development.
Currently, there are only some enterprises that pay attention to recycling and using cast iron slag. Using cast iron slag in cement production brings economic and environmental efficiency, Sua stressed.
"State management agencies should have right policies to deal with cast iron slag, consider it as a by-product in Vietnam’s iron and steel industry to promote the use of cast iron slag,” Sua told Hanoitimes.
Emphasizing the effectiveness of cast iron slag reusing, Chairman of the Vietnam National Cement Association Nguyen Quang Cung also said that Vietnam’s iron and steel industry can make use of this product to improve production efficiency and protect the environment.
