Company profile

researched Aug 2026

STAR'S TECH (Starstech) is a South Korean materials company that upcycles starfish collected as marine waste into three commercial product lines. Its core product, the ECO-ST / ECO-ST1 de-icer, uses porous bone chips obtained from starfish through the company's extraction process as an alternative to calcium chloride and salt, which release chloride ions that corrode metal, damage concrete and kill plants during winter snow removal. The company also sells ECO-SL and states that earlier eco-friendly de-icers failed on performance, price or environmental impact, positioning ECO-ST as addressing those constraints.

A second line, PENELLAGEN, is a cosmetic ingredient based on collagen peptides extracted from starfish, which the company describes as the first collagen ingredient delivered to the dermis layer of the skin using TDS technology. By-products remaining after extraction are commercialized as a natural liquid fertilizer (marketed in Korean as 뢈μ‘₯이 and in English as FERTISTAR), which the company frames as a zero-waste, full-upcycling approach.

The company is headquartered in Mario Tower, Guro-gu, Seoul, with an affiliated corporate research lab in the same building and production plants in Dangjin (Chungcheongnam-do) and Suncheon (Jeollanam-do); its history page also references a Yeosu plant established in 2020. The CEO is Seungchan Yang, and the business registration number is 853-87-00953.

Business model

STAR'S TECH manufactures and sells physical products derived from starfish biomass: the ECO-ST1/ECO-SL de-icers for winter road and infrastructure maintenance, PENELLAGEN collagen ingredient for cosmetics, and a natural liquid fertilizer made from extraction by-products. The company frames its offering around licensed technology rather than commodity product ("Don't buy the product, buy technology"), and operates its own factories in Dangjin and Suncheon.

Latest developments

In 2021 the company established an Eastern European corporation, opened North American de-icer sales including on Amazon, launched a four-kind complex liquid fertilizer, published a CSI-level thesis on Penellagen, registered a Penellagen technology patent, and raised a Series B investment.

β–ΈFull profile β€” market position, technology, go-to-market, geography, history

Market position

The company positions ECO-ST against conventional calcium chloride and salt de-icers and against prior eco-friendly de-icers that it says were limited by performance, price or environmental impact. Korean recognitions include NEP certification, eco-label certification, Excellent Performance Certification, venture certification, selection into the TIPS program, and designation as a Baby Unicorn and First Penguin type startup.

Use of starfish β€” collected as marine waste and cited by the company as a source of annual damage β€” as the feedstock for a chloride-free de-icer, combined with a full-utilization model in which collagen goes to cosmetics and extraction residues to fertilizer, leaving no waste stream.

Technology

The company's process extracts collagen and other substances from starfish; the residual porous bone chips are formulated into the ECO-ST de-icer, avoiding the chloride ions that cause metal corrosion, concrete damage and plant death with calcium chloride and salt. For cosmetics, collagen peptides extracted from starfish are combined with TDS (transdermal delivery) technology in PENELLAGEN to reach the dermis layer. Remaining by-products are converted into liquid fertilizer, giving a zero-waste process. ECO-ST1 technology and Penellagen technology patents were registered in 2018 and 2021 respectively.

Go-to-market

Sales run through Korean public procurement designations for the de-icer, a listed vendor/λ‚©ν’ˆμ²˜ page, direct B2B ingredient supply for PENELLAGEN, and online retail in North America (Amazon and other channels) opened in 2021. The website is published in Korean, English, Japanese and Mongolian.

Public and infrastructure buyers for winter snow-removal (the de-icer was designated an Excellent Product and an Innovative Prototype in the Korean public procurement market), cosmetics formulators purchasing the PENELLAGEN collagen ingredient, and agricultural users of the liquid fertilizer. The company also opened consumer sales of de-icer in North America via Amazon and other channels.

Geography

Headquarters and affiliated research lab in Guro-gu, Seoul, South Korea; factories in Dangjin (Chungcheongnam-do) and Suncheon (Jeollanam-do), with a Yeosu plant established in 2020. An Eastern European corporation was established in 2021 and de-icer sales opened in the North American market the same year.
