JAKARTA, July 24 (Reuters) - Indonesia, the world's most significant palm oil manufacturer, is checking fuel with a view to increasing to 40% from 35% the share of palm-oil blended into biodiesel next year, the energy ministry said.

If implemented, the B40 required might increase biodiesel consumption to approximately 16 million kilolitres (KL) next year, the ministry said, from 13 million KL approximated to be consumed in 2024.

"We hope the trials could be completed in December, so that complete execution of B40 might be performed in 2025," energy ministry senior official Eniya Listiani Dewi stated in a declaration on Tuesday.

The Indonesian Biofuel Producers (APROBI) stated the market had the capacity to fulfill B40 need, with installed capacity anticipated to rise to 20 million KL each year next year from 18 million KL now.

"However we will need more basic materials to fulfill B40 demand," Ernest Gunawan, the secretary general of APROBI informed Reuters on Wednesday.

The biodiesel market would need 13.9 million metric heaps of unrefined palm oil to produce 16 million KL biodiesel next year, from the estimated 11 million tons needed this year, he added.

Indonesia's biggest palm oil association GAPKI stated a decline in exports indicated there would suffice basic materials to provide the B40 mandate for now.

But the market would need to evaluate "which one would be better", GAPKI chairman Eddy Martono stated, referring to the possibility an increase in exports would make supplying the domestic market less feasible.

Indonesia's palm oil output is approximated to reach 54.4 million heaps in 2024, a 2.26% boost from last year, while exports are anticipated to decline by 2.47% to 29.5 million lots as domestic intake rose, driven by biodiesel mandate.

The ministry had checked the biodiesel, blended with 40% of palm oil, on a train for the very first time earlier today, while planning to check the B40 mix on agriculture equipment, power plants and in the shipping industry, it said. (Reporting by Bernadette Christina and Dewi Kurniawati
