Manufacturing

HVO (Hydrotreated Vegetable Oil) is a drop-in renewable fuel that can replace fossil diesel in road vehicles, marine vessels, and aircraft without modification to engines or infrastructure. The mainland facility is designed for an initial production capacity of 270,000 tonnes per year, with a pathway to expand to 500,000 tonnes as regional SAF demand grows. Feedstocks are sourced from sustainable waste streams: used cooking oil, agricultural residues, and palm processing by-products. Hydrotreatment processing uses green hydrogen produced on-site and heat from the geothermal system, achieving a carbon intensity reduction of 80–90% compared to conventional fossil diesel on a life-cycle basis. The HVO plant creates approximately 400 direct jobs.

SYSTEM 3E is a perlite-based modular building system licensed from Poland — a proven construction technology that uses expanded perlite, a volcanic mineral with exceptional thermal insulation and fire resistance properties, as the primary structural and insulation medium. The Mentawai facility operates under exclusive licence for the Indonesian and Southeast Asian market, occupying 20 hectares of the manufacturing district. The facility is designed to produce up to 100,000 modular building units per year using locally available materials supplemented by process minerals from the brine valorisation plant. The most significant initial customer is the Mentawai One programme itself.

The seaplane manufacturing facility is operated as a joint venture between Jekta Switzerland SA and Delta Aerospace, establishing Indonesia's first dedicated amphibious aircraft production centre. The facility focuses on next-generation electric and hybrid-electric seaplanes — aircraft configurations purpose-designed for the island-to-island and coastal routes that define travel across the Indonesian archipelago, the Philippines, the Maldives, and the Caribbean. Aircraft produced here are operated here, creating a built-in development and certification environment. HVO biofuel produced on-site supplies the hybrid-electric test fleet. Approximately 750 direct jobs are created across manufacturing, avionics assembly, quality assurance, test operations, and after-sales service.
