The Bio Diesel Fuel Project by Komatsu, Adaro and United Tractors : Opening Ceremony Held for Pilot Plant

Komatsu Ltd. (President and CEO: Kunio Noji) ("Komatsu"), PT Adaro Energy Tbk (President Director: Garibaldi Thohir) ("Adaro") and PT United Tractors Tbk (President Director: Djoko Pranoto) ("UT") have jointly been advancing the Bio Diesel Fuel*1 (BDF) Project since 2009.

In March this year, the construction of a BDF refinery plant (production capacity: 1.2 tons/day) and an analysis laboratory to ensure the quality of BDF was completed at the Adaro coal mine, and the production of European Standard (EN 14214)-based BDF from Jatropha*2 has begun. After confirming the performance of an engine using the refined BDF on bench test, the project staff members began test operations of a Komatsu-made HD785 dump truck (payload: 90 tons) which is deployed at the mine. To mark a full-scale startup of this project, the three partner companies held a joint opening ceremony of these new facilities on May 31.

This project calls for the production of BDF f rom Jatropha and other plants at the Adaro coal mine in Kalimantan, Indonesia, and the use of BDF as the fuel to run Komatsu-made HD 785 dump trucks in operation at the mine. Ultimately, PT Adaro Indonesia, Adaro's wholly owned subsidiary engaging in mine operations, will plant Jatropha and other plants on the reclaimed land and adjacent areas of the mine, build a BDF supply-chain capable of sustainable local production and consumption, and achieve mine operations with less environmental impact than that of the current mine operations.

The three partner companies will continue to promote this project in order to operate dump trucks on a scale of 100 units in and after 2012. Given that 20% of the currently used mineral diesel fuel will be replaced with BDF to operate them, approximately 8,000 tons of BDF will be used annually and contribute to the reduction of approximately 20,000 tons of CO2 emissions which are roughly equivalent to 10% of CO2 emissions generated by Komatsu manufacturing plants in Japan.


*1 BDF is an alternative fuel to mineral diesel oil, produced from vegetable oil or waste food oil. Popular feedstock plants are soybeans, rapeseed and palm. It is regarded that BDF will not increase the amount of CO2 in the air because the feedstock plants absorb CO2 from the air while they are growing.

*2 Jatropha is considered as one of ideal feedstock plants that produces oil from its inedible seeds and grows even on dry and less fertile soil.
