Our ​Technology
​Significant reduction in environmental impact
The coke reduction process, which was performed twice in the conventional method, is shortened to one time with the Kinotech method.

​This method reduces processes that require large amounts of energy and does not use fire.

This significantly reduces costs and CO₂ emissions.

*The energy consumption values ​​of other companies listed here are only estimated values ​​by our company and do not guaranteed accurate values.

It is possible to produce high-purity zinc equivalent to LME Grade, which was difficult to produce using conventional recycle methods.

Additionally, the equipment of the new Kinotech method can be made more compact, so by installing it on-site (inside the electric furnace factory), it is possible to reduce the transportation costs normally required between the electric furnace and the zinc smelting factory.

​CO₂ emissions breakdown
​Since the use of coke and heavy oil in the process has been replaced by only electricity use, CO₂ emissions in Scope 1 have become zero.
​Significant reduction in environmental impact

Expected CO₂ reduction effect in case that the Kinotech method becomes widespread.

Contributing to the Japanese government's greenhouse gas reduction target by 2030.

​Outline of the Kinotech method for producing zinc
Conventional electric furnace dust treatment technology
Currently, the Waelz method is the mainstream for zinc recycling. New factories are being built around the world.
​Uniqueness and superiority of our technology
​Not only it reduces CO2 emissions, but it also contributes to reducing environmental impact by reusing the residue (mainly composed of iron).
If the cost of recycling zinc falls below the cost of producing it from ore, there is a possibility that electric arc furnace dust, which is currently designated controlled industrial waste, will be treated as valuable material. In addition, zinc, which had previously been disposed of in landfills around the world due to non profitability , will now be recovered, providing a solution to the problem of zinc resource depletion. The new Kinotech method, which recovers iron raw materials at the same time as zinc, will promote the flow of zinc recycling while also contributing to measures against environmental pollution caused by landfill.
