Biofuels made of waste

Tergy Sagava is a Copenhagen-based start-up company (DTU-Spinout) that generates carbon-negative maritime biofuels and sustainable power by revalorising waste.

Opposite to fuels like methanol, which are only suited for new vessels running on dual-engine configurations, Tergy Sagava’s biofuels also target the reduction of CO2 emissions from the major part of shipping companies’ existing vessels that currently run on fossil fuels (95% of all vessels in operation). That is done by replacing the use of fossil fuels with Tergy Sagava’s drop-in TER-SA Biofuel.

Tergy Sagava exclusively uses plant-based biomass, carefully selected from exclusively fair and residual sources without indirect land use change (iLUC) issues.

“Besides our TER-SA Biofuel, we also generate biogas and carbon-negative biochar, effectively capturing CO2 in the process. With our technology, we capture 10 tonnes of CO2-eq per tonne of biofuel. This means that for every 1 tonne of biofuel produced, we have a carbon-sink of 10 tonnes of CO2,” says Jan Octavio Wilske, Co-Founder of Tergy Sagava.

He continues, “At the moment, we are at an advanced stage of biofuel testing – and the grant from the Vissing Foundation is a help in allowing us to produce higher volumes of our products ahead of our next validation and certification steps. We Power Tomorrow with the Waste of Today.”
