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 combined into biodiesel next year, the energy ministry stated.

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

"We hope the trials could be ended up in December, so that full execution of B40 could be performed in 2025," energy ministry senior main Eniya Listiani Dewi stated in a statement on Tuesday.

The Indonesian Biofuel Producers Association (APROBI) said the industry had the capability to satisfy B40 demand, with installed capacity anticipated to rise to 20 million KL annually next year from 18 million KL now.

"However we will require more raw materials to fulfill B40 need," Ernest Gunawan, the secretary general of APROBI told Reuters on Wednesday.

The biodiesel market would need 13.9 million metric lots of crude palm oil to produce 16 million KL biodiesel next year, from the estimated 11 million loads required this year, he added.

Indonesia's biggest palm oil association GAPKI stated a decrease in exports indicated there would be enough basic materials to supply the B40 mandate in the meantime.

But the market would require to examine "which one would be more valuable", GAPKI chairman Eddy Martono stated, referring to the possibility a boost in exports would make supplying the domestic market less feasible.

Indonesia's palm oil output is estimated to reach 54.4 million heaps in 2024, a 2.26% increase from in 2015, while exports are anticipated to decrease by 2.47% to 29.5 million tons as increased, driven by biodiesel mandate.

The ministry had evaluated the biodiesel, combined with 40% of palm oil, on a train for the very first time earlier this week, while preparing to evaluate the B40 mix on agriculture equipment, power plants and in the shipping market, it said. (Reporting by Bernadette Christina and Dewi Kurniawati
