NYK and Nippon Yuka Kogyo Develop New Additive

Nippon Yuka Kogyo Co., Ltd.
NYK
Nippon Yuka Kogyo Co., Ltd., an NYK Group company, and NYK have jointly developed anew fuel-oil additive effective in dispersing sludge* and reducing fuel consumption in VLSFO(very low sulfur fuel oil; sulfur content below 0.5%).
Background
Nippon Yuka Kogyo and NYK have been investigating the properties of VLSFO as one of themeasures to comply with SOx emission requirements,** and in 2019 developed the sludgedispersing fuel oil additive Yunic 800VLS.***
We observed Yunic 800VLS is effective against most of deteriorated compliant fuel oil, andwith taking account into present fuel problem situations, we feel our main target needs to bechanged to reduction of fuel for contribution of environmental protection, from sludge trouble
prevention.
Since we were aware of it, the both companies had been developing Yunic 800VLS “gradeup” version, which is having not only more powerful sludge dispersion characteristics to cover
the rest of stubborn deterioration fuel, but fuel consumption reductions.
About Yunic 800Eco
Yunic 800Eco enhances sludge dispersion and improves combustion. In three fuelconsumption ratio reduction tests conducted with compliant fuel oils in Japan and overseas,
we observed fuel consumption was reduced by up to 1.2% compared to when the additive
was not used, and carbon monoxide (CO) emissions were also reduced.

Future Development
We will continue to work to develop additives that are more fuel-efficient and versatile, while
maintaining the current sludge dispersion effect, and contribute to the reduction of CO2emissions from ships.
In February 2021, NYK released the “NYK Group ESG Story,” which aims to further integrate
ESG into the company’s management strategy and promotes activities that contribute to theachievement of the SDGs through business activities. In March this year, NYK released theupdated “NYK Group ESG Story 2022,” which introduces initiatives for integrating ESG into
the Group’s management strategies set forth in the "NYK Group ESG Story" and provides apartial explanation of the Group’s sustainable growth strategy from a long-term perspective.
To strongly promote ESG management, NYK will actively engage in research anddevelopment for environmental conservation.
