"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 , 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,"
An upcycled de-icing product derived from starfish skeletons melts ice faster than rock salt and reduces chloride pollution that damages roads, bridges, and vehicles. The Northern Pacific sea star is harvested in Korea, where government purchases total 3,000–4,000 tons annually to protect shellfish aquaculture; Stars Tech upcycles about 10% of that material, extracting porous calcium carbonate structures that store and release chloride. The technology originated in high school research on natural pore structures and ion release. ECO-ST costs $465–$650 per ton versus $100–$150 for rock salt, but simulations show substantial lifecycle ROI when infrastructure, reapplication, and ESG benefits are included. ECO-ST is available on Amazon in the U.S.
