What if the solution to winter's
infrastructure corrosion and
environmentally benign home sidewalk de-icing was an invasive starfish being thrown back into Korea's coastal waters? Hando Choi, president of
Star's Tech, joins the conversation to explain how one region's invasive species problem can become another's environmental breakthrough. The company developed
ECO-ST, a de-icing product made from starfish skeletons that not only melts ice faster than conventional rock salt but also reduces the chloride pollution that causes billions of dollars in damage to roads, bridges, and vehicles every winter.
Meanwhile, in Korean waters, the Northern Pacific sea star has become such a menace to shellfish aquaculture that the government purchases 3,000 to 4,000 tons annually to control populations. Stars Tech upcycles about 10% of that collected material, extracting the porous calcium carbonate structures that give starfish their shape and their remarkable ability to store and release chloride. The technology began as a high school science project when founder and chief scientist
Seungchan Yang experimented with natural pore structures to control ion release, eventually connecting that research to the negative impacts of conventional deicers while studying at Seoul National University.
The economic case is compelling once you factor in the full cost of ownership. While ECO-ST runs $465 to $650 per ton compared to $100 to $150 for commodity rock salt, salt itself accounts for less than 5% of most winter maintenance budgets. The
Isaac Walton League of America estimates that infrastructure damage from road salt ranges from $30 to $300 per ton used. Stars Tech's simulations based on U.S. municipal data show ECO-ST can deliver up to 5,000% ROI over time when lower infrastructure maintenance costs, fewer reapplications, and ESG compliance benefits are factored in.
ECO-ST is
available on Amazon in the U.S. and Canada, with retail partnerships launching this winter. You can learn more about Stars Tech at
