Sagava has received a €1.3m convertible loan from BioInnovation Institute to advance its waste-to-fuel technology towards commercial application. The additional financing follows €0.5m previously provided by BII, taking the institute’s total support for the Copenhagen-based DTU spin-out to €1.8m.
Sagava is developing a process that turns waste biomass into marine bio-oil, biochar and hydrogen-rich syngas. DTU says the liquid fuel is designed to require no upgrading or refinery step before integration with existing marine infrastructure. The biochar is intended to retain biogenic carbon, while syngas can provide process heat and power.
The commercial test is fuel qualification at scale
A drop-in fuel proposition matters because shipowners can test lower-carbon fuel without replacing an existing engine fleet. It also puts a demanding burden on Sagava’s scale-up: fuel made from variable waste feedstocks must meet consistent technical specifications, secure reliable supply and demonstrate performance on an operating vessel. The company says its modular process has logged more than 1,500 hours of pilot operation, but the next validation step is still ahead.
Sagava is the commercialisation partner in the EU-funded SEAFAIRER project, which is testing rice husk, biowaste screening material and agave residue as feedstocks. The programme is scheduled to run through August 2028 and culminate in a 30-day vessel demonstration at the Port of Valencia. That test is meant to measure fuel performance and emissions while the consortium develops the life-cycle, cost and business-case evidence needed for market entry.
The convertible loan therefore funds a transition from research and pilot work towards a bankable first commercial system rather than an already proven rollout. BII says the capital is intended to mature the six recipient companies’ technologies and businesses and help them attract outside investment.
Sagava’s economics may depend on extracting value from all three outputs. Marine bio-oil addresses shipping fuel demand; biochar can create a durable carbon-removal product; and syngas can offset part of the plant’s energy requirement. The milestone to watch is whether those co-products support competitive fuel economics once the process leaves controlled pilots and encounters real feedstock, certification and vessel-integration constraints.
