【Unique Technology】
 We have been conducting a research and development of biodiesel technology through ester exchange reaction with direction of Emeritus Professor Shimizu at Kyoto University (as known as the inventor of C-FUEL) and corporation of KRI Co., Ltd before a non-profit organization was established in 1995. After its establishment, we invited some engineers and continuously have made the development effort for our own technology. Since 2009, we have operated the largest plant for biodiesel fuel production in Japan in accordance with the “Zero-Emission Concept,” and have been providing C-FUEL in Japan and EU nations.

【Response from Overseas】
 With competing European plant manufactures, our accumulated know-how on conversion of unstable quality of used cooking oil into the biodiesel fuel was highly evaluated, and we designed and installed the applicable plant for the multiple type of feedstock such as CJO (Jatropha oil), CPO (palm oil), and UCO (used cooking oil) to Petroleum Authority of Thailand (PTT) in 2007. Also, the fuel conversion process of UCO was highly evaluated among environmentally developed nations, and we started to export our biodiesel product “C-FUEL” to Netherland in 2011.

Biodiesel fuel conversion plant in accordance with the “Zero-Emission Concept,” to build such a system aimed at no additional greenhouse gas emission into the natural habitat.

Largest Production Capacity

30,000L/day

The largest biodiesel fuel conversion plant in Japan

Recycling Rate for Used Cooking Oil

97.5%

Up to 97.5% of collected UCO will be converted into biodiesel fuel with less waste and efficient recycle

n Plant Recycling Rate for By-Product Glycerin

100%

Glycerin, by-product of the C-FUEL, is used completely as fuel for on-site boiling equipment


  • The biodiesel fuel produced in our plant is complied with the Japanese Industrial Standards (JIS) stipulated on Feb. 20th, 2008 “automobile fuel – mixing with fatty acid methyl ester.”
    * If correctly performed the used cooking oil was to be collected and stored based on our know-how
  • We are able to produce the biodiesel fuel from the various type of feedstock such as Used cooking oil, Palm oil, Jatropha oil, and other types of vegetable oil.
  • We adopt decompression method in order to reduce oxidation of the fuel at higher temperature.
  • Because it is very high on sealing property due to decompression method, there is no danger of inhaling vaporized methanol or touching directly to the product during its process
