Doosan Enerbility announced on the 16th that it has signed an investment agreement (MOU) with Daegu Metropolitan City for an eco-friendly battery material recycling manufacturing facility. The signing ceremony held at the Sangyeok Government Complex in Daegu was attended by Hong Joon-pyo, Mayor of Daegu Metropolitan City, Jeong Yeon-in, President of Doosan Enerbility, and other officials.

According to the agreement, Doosan Enerbility will establish a high-purity lithium carbonate recovery plant, a core material for secondary battery batteries, on the site of the Daegu National Industrial Complex, adjacent to a large-scale cathode material factory. Daegu Metropolitan City will cooperate administratively and politically by providing ▲land supply ▲permits for infrastructure, construction, and environment ▲support for settlement, finance, and workforce.

Doosan Enerbility developed its own technology to recover lithium from waste batteries in 2021 and completed its demonstration. Last month, it held a board meeting and established a battery recycling specialized subsidiary, Doosan Recycle Solution. Doosan Recycle Solution plans to begin construction of the manufacturing facility in the first half of next year and start recovering lithium by processing about 3,000 tons of raw materials annually from the second half of 2025.

Jeong Yeon-in, President of Doosan Enerbility, said, “We decided to build the manufacturing facility in the Daegu National Industrial Complex, which has good geographical accessibility due to the proximity of a large-scale cathode material factory. Through this agreement, we will quickly apply Doosan Recycle Solution’s lithium recovery technology to contribute to the revitalization of the secondary battery industry.”

The lithium recovery technology developed by Doosan Enerbility involves heat-treating the internal materials of waste batteries, separating lithium using distilled water, and extracting lithium carbonate through crystallization technology. Compared to existing technologies, this process is simpler and more economical, and as an eco-friendly method that does not use chemicals, it has the advantage of significantly improving lithium purity and recovery rate.
