Turning local marine’s waste into eco gems

problem

Korea has the world's second-largest oyster production, 80% of which is produced in Tongyeong. However, in order to obtain 40,000 tons of oysters out of 350,000 tons of annual oyster production, as many as 310,000 tons of oyster shells are released as marine by-products, generating nearly eight times as much marine waste. Over the past 20 years, the oyster industry process has remained unchanged, and is now stacked at more than 1 million tons. There is no way to dispose of oyster shells properly, so we are discarding them in East Sea.

mission

GREENOCEANS aims to protect the environment by providing fundamentally sustainable materials at the intersection of Environment, Design and engineering and proposing solutions using aquatic products as materials to help local ocean change become global.

4 Main issues in the oyster industry

Awful Smell

press coverage
Problem
The oyster shells, when discarded, produce a strong and unpleasant odor that can be harmful to the environment and the people living nearby.

Pest breeding

press coverage
Problem
The accumulation of oyster shells can create a breeding ground for pests and insects, which can cause further damage to the environment.

Release of leachate

press coverage
Problem
The oyster shells can release harmful chemicals and pollutants into the environment, which can contaminate the soil and water sources.

Desertification

press coverage
Problem
The accumulation of oyster shells can lead to desertification of the surrounding land, making it difficult for plants and animals to survive.

Why the oyster shell is Eco-gems?

Oyster shells are a sustainable and eco-friendly material that can be used in various applications, such as construction, agriculture, and art. By repurposing oyster shells, we can reduce waste and promote a circular economy.

Oysters purify 5L of water per hour as they grow. It also collects carbon dioxide to purify pollutants in the sea and grow shells up to 200 liters per day.
