How Does Neste Company Work?

How is Neste leading the green fuel shift?

Neste transformed from a regional refiner into the world’s leading producer of renewable diesel and SAF, reaching a 5.5 million tons/year renewable capacity by early 2025. Its NEXBTL tech converts waste and residues into high‑quality fuels and feedstocks.

Neste operates three segments—Renewable Products, Oil Products, and Marketing and Services—leveraging proprietary conversion tech and global refinery expansions to capture demand driven by mandates like the EU ReFuelEU Aviation rule. See strategic pressures in Neste Porter's Five Forces Analysis.

Neste decarbonizes hard-to-abate sectors by converting waste and residues into drop-in renewable fuels using its proprietary NEXBTL technology, supported by integrated feedstock sourcing and global refining hubs.

Feedstock-flexible refining

NEXBTL processes over 10 feedstock types; ~90% of inputs are waste and residues such as used cooking oil and animal fats, minimizing food-versus-fuel risks.

High GHG reduction

NEXBTL-based products can cut lifecycle greenhouse gas emissions by up to 90% versus fossil fuels, enabling immediate carbon reductions in transport and aviation.

Global refining footprint

Three major hubs in Porvoo, Singapore, and Rotterdam form an integrated production network; Singapore is the world’s largest integrated SAF facility as of 2025.

Vertical integration into sourcing

Acquisitions of feedstock aggregators in the US and Europe create a supply moat, reducing exposure to volatile spot markets and securing feedstock for scaling renewable diesel and SAF.

The Neste business model delivers drop-in renewable diesel, sustainable aviation fuel, and feedstock for chemicals, generating revenue from fuel sales, SAF contracts, and intermediate products while supporting customers' ESG targets.

Operational advantages and value chain impacts

Neste’s combination of NEXBTL technology, waste-centric sourcing, and global refining enables fast decarbonization without infrastructure overhaul, strengthening its position in the circular economy.

• Robust feedstock network lowers price and supply volatility risk
• Drop-in products allow immediate adoption by airlines, shippers, and petrochemical users
• Vertical integration improves traceability and sustainability compliance
• Scale in SAF production supports growing aviation decarbonization mandates

Neste’s revenue mix is dominated by Renewable Products, which in recent years accounted for roughly 70–80% of comparable EBITDA; key monetization is sale of renewable diesel and SAF to corporate customers, distributors and airlines, supported by Marketing & Services and legacy Oil Products cash flow.

Renewable Products

Sale of renewable diesel, HEFA and SAF to airlines, distributors and large corporates. SAF contracts prioritized due to regulatory demand and higher margins.

SAF Capacity Target

Targeting 1.5 million tonnes annual SAF capacity to serve ReFuelEU and global airline demand, capturing price premiums vs conventional biofuels.

Oil Products

Refining and sale of fossil fuels and chemicals generates multi‑billion euro sales annually and funds renewable investments; operations remain volatile with commodity cycles.

Marketing & Services

Retail network of over 1,000 service stations in the Nordics and Baltics provides fuel retail, convenience sales and margin diversification.

Renewable Polymers & Chemicals

Licensing and supply agreements for bio‑based plastic precursors with global brands generate fee and supply revenues outside transport fuel markets.

Feedstock & Value Chain

Revenue stability tied to feedstock sourcing, with increasing use of waste and residue oils to improve margins and meet sustainability criteria across the Neste business model.

Key monetization moves align with regulations and customer contracts while leveraging technical differentiation and scale.

Monetization Levers

Revenue generation focuses on high‑margin SAF contracts, integrated sales channels and downstream licensing to capture value across the Neste value chain.

• Prioritise SAF sales to airlines under ReFuelEU demand starting 2025
• Use Oil Products cash flow to finance renewable capacity build‑out
• Expand renewable polymers licensing to diversify income
• Scale feedstock sourcing of waste/residues to protect margins

Neste’s recent strategic expansion and technology focus have driven rapid growth in renewable fuels and SAF, securing scale, feedstock flexibility, and market access across Europe, Asia and North America. Key investments and agile commercial responses have reinforced its low-carbon positioning and cost competitiveness.

Major Capacity Expansions

The €1.6 billion Singapore refinery expansion doubled site capacity and added dedicated SAF lines, lifting Neste's global renewable production capacity significantly.

North American Footprint

The Martinez Renewables joint venture with Marathon Petroleum established a strategic US base, unlocking benefits from California LCFS and federal tax credits for SAF and renewable diesel.

Economies of Scale

Scale from recent projects has reduced unit costs and improved utilization; Neste reported a 2025 production capacity exceeding 3 million tonnes of renewable products annually across its network.

Brand & Sustainability Leadership

Neste ranks consistently high in sustainability indices and Corporate Knights listings, reinforcing premium positioning for low-carbon fuels and SAF.

Operational and commercial resilience has been tested by market swings; a 2024 dip in renewable margins prompted a sharpened sales mix toward SAF and accelerated cost-efficiency programs to protect margins and cash flow.

Competitive Edge & Strategic Capabilities

Neste’s competitive advantage stems from proprietary refining technology, broad feedstock acceptance, and an integrated global value chain that supports regulatory and commercial benefits.

• Technology: proprietary NEXBTL-based processes enable conversion of low-quality residues into high-quality renewable diesel and SAF, lowering feedstock costs and carbon intensity.
• Feedstock flexibility: ability to process waste oils and residues versus competitors reliant on high-grade vegetable oils improves margins and sustainability metrics.
• Market access: investments in Singapore and Martinez increase geographic reach and allow capture of policy incentives like LCFS and US tax credits.
• Commercial agility: in response to 2024 margin pressure from higher US supply, management shifted sales mix to SAF and enacted cost programs to sustain profitability.
