Biodiesel fuel (BDF) is attracting attention as an energy source that contributes to reducing greenhouse gas emissions,
which are considered to be the cause of global warming, and contributes to reducing environmental impact.
From the perspective of creating a recycling-oriented society,
we can manufacture biodiesel fuel using plant-based waste cooking oils as raw materials,
and use it as a substitute fuel for regular diesel oil or heavy oil.
Biodiesel fuel
Biodiesel fuel differs from petroleum and other fossil fuels
because it is made from waste cooking oils, making it environmentally friendly.
Since the plants used as raw materials for biofuels absorb CO2 from the atmosphere as they grow,
they don't introduce additional CO2 into the atmosphere, thereby contributing to a reduction in environmental impact.

Product lineup
FKB5
B5 diesel
|
A fuel mixture of 5% biodiesel fuel with regular diesel. In addition to reducing CO2 emissions by approximately 5%, it also meets the mandatory standards for diesel fuel under the Quality Control Act*, and can be used in the same way as diesel fuel. |

---|---|---|
FKB30
B30 fuel
|
By mixing 30% biodiesel fuel with regular diesel, CO2 emissions can be reduced by approximately 30%. It is used for off-road applications only, but is characterized by a high CO2 reduction rate. |
|
FKB100
B100 fuel
|
Uses 100% biodiesel fuel and is excluded from CO2 emission calculations. It can be used as an on-road and off-road diesel fuel and heavy oil alternative. |
|
FKBxH
Bio-heavy oil
|
A mixture of biodiesel fuel and heavy oil that is used as a heavy oil alternative. It is mainly used as a fuel for industrial boilers and as a marine fuel. |
* Quality Control Act: the Act on the Quality Control of Gasoline and Other Fuels. The purpose of the act is to establish quality standards and labeling obligations for fuels such as gasoline and diesel, and to prevent the leakage of non-compliant fuels.
Case studies

Using B5 diesel fuel in our own delivery trucks
We aim to reduce CO2 emissions from our warehouses and transportation vehicles by 50% (approximately 2,600 tons) compared to emissions in 2019.
Industry | Transportation |

Customer | Suntory Logistics |
Oil used | B5 diesel |
Application | Delivery trucks |

B100 fuel was used at the construction site for a large expo.
The customer is working to reduce construction-related CO2 emissions by 75% by 2030, with FY2013 as the base year.

Customer | Konoike Construction |
Oil used | B100 fuel |
Application | Generators and crawler cranes |

We delivered B5 diesel fuel for use at construction sites by a major general contractor.
The general contractor will achieve a 42% reduction in CO2 emissions within its Group by FY2030, with FY2020 as the base year (approximately 60,000 tons).

Fuji Kosan's functions and delivery process
Our functions range from waste cooking oil collection to refining, mixed manufacturing, and supply of biodiesel fuel.
We propose necessary functions according to customer needs.

Circular economy
Regional energy recycling
using waste cooking oil
We collect waste cooking oil, the raw material for biodiesel production, through our partner companies, refine it, and supply it as biodiesel, thereby forming a cycle of resource circulation.
This is called "circular economy." The purpose is to avoid waste and make good use of local resources.
