In addition, Nippon Kaiji Kyokai (Class NK) certified that nitrogen oxygen (NOx) emissions from the vessel during BDF combustion are within emissions limits set by international regulations including the MARPOL Treaty. This is the first certification by Class NK in Japan.

BDF used for the vessel as fuel is fatty acid methyl ester generated through transesterification (Note 1) of collected waste cooking oil with methanol.

BDF is a biomass energy resource, which exhausts carbon dioxide (CO2) during combustion, but the plants that provide its raw material absorb CO2 and reproduce biomass, so CO2 emissions during combustion can be reduced. BDF supplied for the vessel is used by increasing mixing ratio with Class A heavy fuel to more than 30% first time in Japan, which is expected to reduce CO2 emissions by 25-30%.

The MOL Group set a target of achieving net zero GHG emissions by 2050 in “MOL Group Environmental Vision 2.1” (Fig.1) announced in June 2021. It calls for an initiative on “Adoption of Clean Alternative Fuels” (Fig. 2) to achieve this target, positioning biomass as an effective alternative to fossil fuels. The group works continually not only to reduce GHG emissions from its own operations, but also to meet the demands by customers and society at large to protect the global environment.
