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

If executed, the B40 required might increase biodiesel consumption to up to 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 completed in December, so that complete execution of B40 might be brought out in 2025," energy ministry senior official Eniya Listiani Dewi said in a statement on Tuesday.

The Indonesian Biofuel Producers Association (APROBI) said the industry had the capability to meet B40 need, with set up capability anticipated to rise to 20 million KL each year next year from 18 million KL now.

"However we will require more basic materials to meet B40 demand," Ernest Gunawan, the secretary general of APROBI told Reuters on Wednesday.

The biodiesel industry would require 13.9 million metric loads of unrefined palm oil to produce 16 million KL biodiesel next year, from the approximated 11 million lots needed this year, he included.

Indonesia's biggest palm oil stated a decline in exports indicated there would be sufficient raw materials to supply the B40 mandate in the meantime.

But the market would need to evaluate "which one would be more important", GAPKI chairman Eddy Martono said, describing the possibility a boost in exports would make providing the domestic market less viable.

Indonesia's palm oil output is approximated to reach 54.4 million tons in 2024, a 2.26% boost from in 2015, while exports are anticipated to decrease by 2.47% to 29.5 million loads as domestic intake rose, driven by biodiesel required.

The ministry had actually checked the biodiesel, combined with 40% of palm oil, on a train for the first time previously today, while preparing to evaluate the B40 mix on agriculture machinery, power plants and in the shipping market, it said. (Reporting by Bernadette Christina and Dewi Kurniawati
