JAKARTA, July 24 (Reuters) - Indonesia, the world's greatest 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 said.

If carried out, the B40 required might 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 ended up in December, so that full execution of B40 might be brought 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 fulfill B40 demand, with set up capability expected to increase to 20 million KL every year next year from 18 million KL now.

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

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

Indonesia's biggest palm oil association GAPKI stated a decline in exports implied there would be enough basic materials to supply the B40 required for now.

But the industry would require to evaluate "which one would be better", GAPKI chairman Eddy Martono said, referring to the possibility an increase in exports would make providing the domestic market less feasible.

Indonesia's palm oil output is approximated to reach 54.4 million heaps in 2024, a 2.26% increase from last year, while exports are expected to decline by 2.47% to 29.5 million lots as domestic usage rose, driven by biodiesel required.

The ministry had tested the biodiesel, combined with 40% of palm oil, on a train for the first time previously today, while preparing to check the B40 mix on agriculture equipment, power plants and in the shipping market, it said.
