LISBON, Dec 19 (Reuters) - Portugal's Galp Energia anticipates to start producing biodiesel and biojet fuel from waste in an industrial-scale unit it is developing at its Sines refinery in 2026, the business, which is primarily an oil producer and refiner, stated on Thursday.

In 2015 Galp got in into a 75%-25% joint endeavor with Japan's Mitsui to invest 400 million euros ($415 million) in the Hydrogenated Grease (HVO) plant, which will have a production capability of 270,000 metric heaps per year.

It will change waste materials, such as used cooking oils, into renewable biodiesel and biojet fuel, likewise understood as sustainable aviation fuel (SAF), utilizing green hydrogen produced by an electrolyser powered by wind or solar power.

Galp stated in a statement it got on Wednesday the 3 reactors to biofuels, which will permit the HVO system to "produce SAF and biodiesel in 2026 ... placing Galp at the leading edge of developing low-carbon options necessary for the energy shift".

Galp is also investing 250 million euros in a 100 megawatt (MW) electrolyser system to produce green hydrogen to power the refinery in Sines. ($1 = 0.9637 euros) (Reporting by Sergio Goncalves
