JAKARTA, July 24 (Reuters) - Indonesia, the world's most significant palm oil producer, 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 stated.

If implemented, the B40 required might increase biodiesel usage to as much as 16 million kilolitres (KL) next year, the ministry stated, from 13 million KL approximated to be consumed in 2024.

"We hope the trials could be ended up in December, so that complete implementation of B40 might be brought out in 2025," energy ministry senior main Eniya Listiani Dewi said in a declaration on Tuesday.

The Indonesian Biofuel Producers Association (APROBI) stated the market had the capacity to satisfy B40 need, with set up capacity anticipated to increase to 20 million KL yearly next year from 18 million KL now.

"However we will require more raw 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 lots of unrefined palm oil to produce 16 million KL biodiesel next year, from the estimated 11 million heaps required this year, he included.

Indonesia's greatest palm oil association GAPKI said a in exports meant there would suffice raw products to provide the B40 required in the meantime.

But the industry would require to examine "which one would be more important", GAPKI chairman Eddy Martono said, describing the possibility a boost in exports would make supplying the domestic market less practical.

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

The ministry had actually evaluated the biodiesel, mixed with 40% of palm oil, on a train for the first time earlier today, while preparing to evaluate the B40 mix on agriculture equipment, power plants and in the shipping industry, it stated. (Reporting by Bernadette Christina and Dewi Kurniawati
