SEOUL, July 15 (Korea Bizwire) — South Korean builder SK ecoplant Co. said Thursday it was launching a drive to recycle waste incineration ash as a construction material.
The company joined hands with CMD Group, a specialist in the manufacturing of eco-friendly construction materials, to promote technological cooperation and to produce block aggregates made of recycled incineration ash.
SK ecoplant will provide incineration ash generated from its incineration facilities, while CMD Group will mix it with concrete to manufacture large wall blocks and sidewalk blocks.
After going through technology and safety reviews, these products will be used on SK ecoplant’s construction projects.
According to the Korea Environment Corp., South Korea’s waste incineration facilities were processing about 9.1 million tons per year as of 2020. The amount of incineration ash generated stood at about 2.2 million tons.
After conducting tests using various exothermic chemical reaction materials, the two companies found that pollutants and bad odors were removed and compressive strength was greatly increased.
