JAKARTA, July 24 (Reuters) - Indonesia, the world's most significant palm oil producer, is evaluating 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 could increase biodiesel consumption to up to 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 finished in December, so that full implementation of B40 could be performed in 2025," energy ministry senior main Eniya Listiani Dewi stated in a declaration on Tuesday.

The Indonesian Biofuel Producers Association (APROBI) stated the market had the capability to meet B40 demand, with anticipated to rise to 20 million KL yearly next year from 18 million KL now.

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

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

Indonesia's greatest palm oil association GAPKI stated a decline in exports meant there would suffice basic materials to supply the B40 required in the meantime.

But the industry would require to evaluate "which one would be better", GAPKI chairman Eddy Martono said, 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 loads in 2024, a 2.26% boost from in 2015, while exports are expected to decrease by 2.47% to 29.5 million tons as domestic usage increased, driven by biodiesel required.

The ministry had actually tested the biodiesel, combined with 40% of palm oil, on a train for the very first time previously this week, while preparing to test the B40 mix on farming equipment, power plants and in the shipping market, it stated. (Reporting by Bernadette Christina and Dewi Kurniawati
