From Waste to Worth: Green Oceans Pioneers Eco-Amiable Solutions
In a groundbreaking move towards sustainability, Green Oceans, a dynamic startup based in Tongyeong, gyeongnam, is revolutionizing the management of marine fisheries by-products. Spearheaded by CEO Moonpia, the company is transforming discarded oyster shells, of which South Korea produces over 200,000 tons annually, into a range of innovative, eco-friendly upcycling products. This commitment to marine environment preservation and resource recycling has earned Moonpia the prestigious Minister of Maritime affairs and Fisheries award.

Calcium Carbonate: the Key to Innovation
at the heart of Green Oceans’ innovation lies calcium carbonate, the primary component of oyster shells. Leveraging this abundant resource,the company has developed a diverse portfolio of eco-conscious products,including:
- art education supplements
- Plastic filling materials
- Multi-use containers
- Architectural boards
- Artificial leather fabrics
This innovative approach not only addresses the environmental challenge posed by oyster shell waste but also creates valuable materials for various industries. The global calcium carbonate market is projected to reach $32.7 billion by 2027, highlighting the critically important economic potential of this resource.
Collaborations Drive Sustainable Growth
Green Oceans’ success is further amplified thru strategic collaborations. The company supplies eco-friendly artificial leather materials to major domestic corporations, facilitating the progress of new, sustainable products. This has opened doors for applications in diverse sectors, including diaries, shoes, and fashion accessories, transforming what was once considered waste into valuable industrial materials.
The growth of Green Oceans is thanks to the cooperation of various institutions and local residents.
