Differentiation of development technology


Scientific and technological aspects

Economic and industrial aspects

Social Aspect

Contributing to the development of catalyst technology

◾ Contribute to price competitiveness, energy reduction, 

and low carbonization in the petrochemical industry

◾ Vitalize the field of catalyst research with technologies related to 

catalyst restoration, synthesis, and reactor design

 Rare metal recovery

◾ Vanadium-hydrogen production catalyst and nickel battery 

materials can be used directly

◾ Rare earth resources can be secured through the recovery of 

rare earth elements such as lanthanum.

Reduce dependence on resource imports

◾ Through recycling of valuable metals such as rare earths, 

vanadium, and nickel, which are highly dependent on imports.

Can contribute to securing resources and localizing materials

Expansion of high value-added markets

◾ Effect of entering the domestic remanufacturing market worth KRW 1 trillion

◾ Technology export is possible through overseas expansion and commercialization.

Building a sustainable society

◾ Contributes to reducing wastewater and residues generated during disposal

◾ Creating social value through carbon neutrality and eco-friendly businesses that respond to climate change

Professional manpower training and employment effects

◾ Capable of nurturing professional manpower in the field of director, cutting-edge analysis technology, and standardization technology.

◾ Commercialization of the plant has the effect of employing more than 70 people.
