Chokepoint2026
Neste controls approximately 50–75% of global HEFA-SAF supply at 1.5 million tonnes/year capacity (April 2025), against an estimated global total of ~2 million tonnes/year. A single operational disruption at Singapore or Rotterdam — fire, maintenance outage, regulatory shutdown — would immediately collapse global SAF availability, disabling airline SAF compliance with EU ReFuelEU Aviation mandates and US IRA tax credit programs. The Singapore refinery had a production restart event in 2024. Additionally, active fraud investigations into Malaysian UCO and Indonesian POME suppliers (Indonesian police detained 11 suppliers in early 2025) threaten the feedstock provenance certifications on which Neste's EU RED compliance and US tax credit eligibility (EUR 153M in 2025) entirely depend.

Neste, publicly known as the world's leading sustainable aviation fuel producer, is also one of Europe's largest processors of slaughterhouse waste. Through its 80%-owned Neste Demeter B.V. (formerly IH Demeter, acquired starting 2018) and 100%-owned Walco Foods (Ireland), Neste is a major trader of Category 3 animal fats — the lowest-grade rendering waste from European meat processing, including tallow from cattle, pigs, and poultry that is unsuitable for human or animal consumption. These fats flow directly into Neste's refineries as feedstock for SAF and renewable diesel. An airline buying Neste SAF to meet its sustainability targets is, at some distance, burning rendered slaughterhouse fat. The meat rendering and aviation fuel supply chains are the same supply chain.
The Irish Times ↗Origin2026
Neste began as a state-owned petroleum refinery (Neste Oil) founded in 1948 to secure Finnish energy independence during the Cold War. The renewable fuels pivot began in 2007 when Neste commercialized its proprietary NEXBTL hydroprocessing technology — initially producing renewable diesel from palm oil — at Porvoo. After EU palm oil restrictions tightened, Neste shifted to waste and residue feedstocks, making a series of vertical integration acquisitions: Neste Demeter (European animal fat trader, 80%), Mahoney Environmental (US restaurant grease collection), Walco Foods (Irish animal fat trader), and Crimson Renewable Energy (US UCO). These acquisitions transformed a petroleum refiner into a vertically integrated waste-to-fuel company. The Finnish government retains 44.2% ownership with a Parliamentary floor of 33.4%.
Neste Corporation ↗Capacity2026
Neste's Renewable Products capacity reached 4.1 million tonnes/year in 2025 and is expanding to 6.8 million tonnes/year by 2027 via the EUR 2.5B Rotterdam refinery expansion. The Singapore refinery (2.6M t/yr total, 1M t/yr SAF-capable) is the single largest renewable fuels refinery in the world. The Porvoo conventional crude oil refinery (currently ~10M t/yr crude throughput, 100+ petroleum products) is planned for full transformation to renewables and circular solutions refining by the mid-2030s, ending conventional petroleum operations. The total EUR 5B+ investment commitment across Singapore, Rotterdam, and Porvoo represents the largest bet on regulatory SAF mandates by any single company.
