Nova Pangaea Completes 72-Hour SAF Endurance Trial at Teesside

Nova Pangaea Technologies (NPT) has completed a 72-hour continuous endurance trial of its REFNOVA technology at its Teesside demonstration plant in the United Kingdom, validating a process that converts waste biomass into bioethanol for Sustainable Aviation Fuel (SAF) production.

Announced in a press release on August 24, 2026, the milestone demonstrates a scalable alternative to hydroprocessed esters and fatty acids (HEFA) derived from used cooking oil. The HEFA pathway currently dominates the SAF market but faces supply constraints and escalating costs as competition intensifies across biofuel sectors.

Scaling waste-to-fuel technology

During the trials, the Teesside facility processed up to three tonnes of softwood residues per day, maintaining stable operation for up to 72 hours. The successful run follows initial smaller-scale tests conducted in early 2025 that proved the viability of the REFNOVA process outside laboratory conditions.

NPT Chief Executive Officer Stewart Stewart stated in the press release that the trials validate the technology and will support investor confidence as the company moves toward constructing its first commercial plant.

To date, NPT has raised over £21 million from investors including International Airlines Group (IAG), Mercia Ventures, and UK government grants. The company plans to conduct further trials in 2027 to refine the design of its commercial-scale facilities.

Project Speedbird and UK SAF mandates

The technological validation directly supports Project Speedbird, a joint initiative between NPT, LanzaJet, and British Airways. Backed by the UK government’s Advanced Fuels Fund, the project aims to develop domestic SAF production capabilities using agricultural and wood waste. Under this initiative, NPT plans to construct four UK facilities to produce bioethanol.

The push for domestic production aligns with the UK SAF Mandate, which requires 3.6% of jet fuel supplied in 2026 to come from sustainable sources. This requirement scales to 10% by 2030 and 22% by 2040.

Speaking to SAF Investor, Stewart emphasized the urgency of diversifying feedstocks amid rising demand and geopolitical supply chain shocks.

“Nova Pangaea’s tried and tested technology offers a genuine alternative. By tapping into the plentiful supplies of waste biomass, we can boost SAF production, enhancing our energy security, and building a new domestic industry that generates jobs and revenues while reducing fossil fuel emissions,” Stewart told the publication.

AirPro News analysis

We view the successful endurance trials at Teesside as a necessary step toward breaking the aviation industry’s reliance on used cooking oil and waste animal fats. While HEFA-based SAF has proven the viability of drop-in replacement fuels, the limited global supply of waste oils creates a hard ceiling on production capacity.

Unlocking agricultural and forestry waste as a feedstock opens a significantly larger volume of raw material. The International Air Transport Association (IATA) estimates that available waste biomass in Europe and the UK could yield 30 million tonnes of SAF by 2030. Beyond volume, the REFNOVA process generates biochar as a byproduct. This creates a carbon-negative fuel lifecycle, which will become increasingly valuable to airlines as regulatory frameworks tighten around lifecycle emissions accounting.
