What does it do? Founded in 2022, Green-DA recovers oil from frying-batter waste discarded by restaurants and food factories, converting it into feedstock for bio-based fuels. It runs the full SAF feedstock value chain, from collection and pre-treatment to refining, quality control, and supply.

The numbers: Green-DA posted 8.9 billion KRW in revenue in the first half of this year, a roughly 1,000% jump from the same period a year earlier. It now serves about 2,500 clients and holds the ISCC EU and ISCC CORSIA sustainability certifications needed to enter European and global aviation markets.

What's the endgame? The company plans to expand its collection network, upgrade production infrastructure, and hire technical talent. "This investment recognises Green-DA's technology, feedstock sourcing edge, and global growth potential," said chief executive officer Hwang Kyu-yong, adding that it aims to "leap into a global climate-tech company."

The signal: A quick re-raise backed largely by returning investors — plus a bank and corporate venture arm — points to steady conviction in SAF supply. As airlines face tightening carbon rules, feedstock suppliers with certified value chains are positioning early for a market that hinges on scarce, verified raw material.
