JAKARTA, July 24 (Reuters) - Indonesia, the world's greatest palm oil manufacturer, is evaluating 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 mandate could increase biodiesel intake to up to 16 million kilolitres (KL) next year, the ministry stated, from 13 million KL estimated to be consumed in 2024.

"We hope the trials could be ended up in December, so that full implementation of B40 could be carried out 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 need, with set up capability expected to rise to 20 million KL every year next year from 18 million KL now.

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

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

Indonesia's greatest palm oil association GAPKI said a decline in exports indicated there would be adequate basic materials to provide the B40 required in the meantime.

But the industry would require to examine "which one would be better", GAPKI chairman Eddy Martono said, describing the possibility an in exports would make supplying the domestic market less feasible.

Indonesia's palm oil output is estimated to reach 54.4 million lots in 2024, a 2.26% boost from in 2015, while exports are anticipated to decline by 2.47% to 29.5 million lots as domestic usage rose, driven by biodiesel mandate.

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