On February 11, 2026, a groundbreaking partnership was announced at Suncheon City Hall in South Korea, signaling a bold new direction in the fight against climate change. LG Electronics, in collaboration with Suncheon City and the Seoul National University Blue Carbon Project Group, signed a Memorandum of Understanding (MOU) to jointly develop blue carbon ecosystems and accelerate carbon neutrality efforts. The centerpiece of this initiative? An innovative material called 'Marine Glass,' set to be deployed across 1,500 square meters of the Suncheonman tidal flat—a UNESCO World Natural Heritage site renowned for its ecological richness.
So, what exactly is Marine Glass, and why does it matter? According to reports from Straight News and Munhwa Ilbo, Marine Glass is a functional glass material that transforms into mineral ions when it comes into contact with water. This transformation allows it to supply essential minerals, at controlled rates and quantities, directly to seaweed and halophytes—salt-tolerant plants that thrive in coastal environments. By providing these minerals precisely where and when they’re needed, Marine Glass aims to supercharge the growth of these marine organisms, which play a crucial role in capturing and storing atmospheric carbon dioxide.
Blue carbon, the term for carbon captured by oceanic and coastal ecosystems, has become a hot topic in climate science circles. Tidal flats, salt marshes, and seagrass meadows all act as natural carbon sinks, helping to offset greenhouse gas emissions. The Suncheonman tidal flat, with its unique biodiversity and vast stretches of halophyte colonies, is an ideal testing ground for this innovative approach. LG Electronics’ pilot project will focus on verifying both the growth of halophytes and the efficiency of carbon absorption after the application of Marine Glass.
What sets Marine Glass apart from other mineral supplements? Flexibility. The material can be customized in type, quantity, and shape to suit various environmental conditions. For instance, in areas where water currents are particularly swift, Marine Glass can be manufactured as heavy spherical beads or flat chips, preventing the mineral content from dispersing too quickly. This adaptability ensures that minerals remain available to the plants for longer periods, maximizing their growth and, by extension, their carbon-capturing potential.
LG Electronics has invested heavily in proprietary technology to precisely control the dissolution of mineral components in Marine Glass. As Kim Young-seok, head of the company’s HS Functional Materials Business Office, stated, "We plan to strengthen our competitiveness through this new material business." He further emphasized the dual mission of the project: "Contributing to environmental preservation and carbon problem solving while developing a sustainable new material business." (Straight News).
The MOU signing ceremony brought together key figures, including Kim Young-seok and Suncheon Mayor Noh Kwan-gyu, underscoring the collaborative spirit of the venture. The agreement doesn’t stop at the current pilot project. The three parties have outlined plans to expand their cooperation to include the creation and conservation of blue carbon ecosystems, the formation of new halophyte colonies, and the establishment of long-term ecological management models within the Suncheonman tidal flat. The ambition is clear: to turn this corner of South Korea into a model for sustainable blue carbon management that could inspire similar efforts worldwide.
This isn’t LG Electronics’ first foray into blue carbon innovation. In late 2025, the company partnered with Busan Metropolitan City to launch a similar pilot project in the Nakdong River estuary salt marsh wetlands, applying Marine Glass to boost halophyte growth and carbon absorption. These early efforts have paved the way for the Suncheonman project, demonstrating LG’s commitment to scaling up its new material research and development (R&D) activities.
Marine Glass is just one component of LG Electronics’ broader push into glass powder-based functional materials. Since 2013, the company has been steadily building a portfolio of innovative products leveraging the unique properties of glass powder. Notable examples include 'Purotec,' an antimicrobial and antifungal material that can be added to plastics, paints, and rubber to suppress odors and contamination caused by microbes, and 'Mineral Wash,' a functional laundry material that can replace conventional surfactants in detergents, offering potential benefits in water and power savings. According to Straight News, LG Electronics has filed 420 patents related to glass powder technology, underlining its leadership in this niche but rapidly growing sector.
The collaborative approach doesn’t end with Suncheon City and Seoul National University. LG is also working with the National Water Industry Cluster Project Group and the Korea Water Forum to verify the laundry performance and resource-saving effects of Mineral Wash-based detergents. These partnerships reflect a broader strategy to nurture new business-to-business (B2B) ventures and foster innovation across multiple sectors.
The Seoul National University Blue Carbon Project Group, for its part, is actively pursuing new business opportunities and joint technology development to invigorate the domestic and international blue carbon industry. Their expertise in marine ecology and ecosystem management is expected to play a pivotal role in ensuring the scientific rigor and success of the Suncheonman pilot project.
Why does all of this matter? As the world grapples with the escalating impacts of climate change, innovative solutions that harness natural processes to sequester carbon are gaining traction. Blue carbon ecosystems, though often overlooked compared to forests and terrestrial carbon sinks, hold immense promise. The Suncheonman initiative stands out not just for its technological ingenuity, but for its collaborative, cross-sectoral approach—a model that could be replicated elsewhere as nations seek to meet their carbon neutrality targets.
For LG Electronics, the move represents a strategic pivot toward sustainability and long-term competitiveness. As Kim Young-seok succinctly put it, "We will contribute to environmental preservation and solving carbon issues, while further developing a sustainable new material business to strengthen our competitiveness."

As the Marine Glass project gets underway in the Suncheonman tidal flat, all eyes will be on the results. Will this novel material deliver on its promise to boost halophyte growth and turbocharge blue carbon capture? If successful, it could mark a turning point in the way industries, governments, and academia join forces to tackle the climate crisis—one tidal flat at a time.
