For centuries, in the Arkachan Bay, the astroculcher has been practiced, which creates some of the best mallus in the world. But this department faces an important challenge: as the Astrioticist Benjamin Leeron explained, most oysters die before collected: “From the collection of oysters I categorized yesterday, I had 50% of death, which was already significant. But some of my colleagues face 80-90% of losses.”
This death produces thousands of tons of shell waste per year. Instead of viewing them as garbage, the Regional Marisco group collects and reuses them.
“We are looking for new exit to continue to increase the additional value of production,” says Mathiyu Kapasel, director of the regional Marisko committee of Akwitin’s Arkacha. “With actual repetition at the local level, we are trying to create innovative projects with local delivery chains as possible.”
An innovative application Professor David Grakoire belongs to the University of PAU and pays T’L’Nongour. They have created an environmental concrete based on crushed sea bombs instead of traditional sand and gravel, combined with cement without the clinker that releases 75% less CO₂ than regular construction cement.
“They are in fiber by nature,” Professor Gracoire explains. “Regular concrete, when it is compressed, scattered, there is a concrete, and it will gradually break and maintain its shape. Another significant advantage is that the concrete is very aesthetic. When it is polished, the bombs are found, so a substance that represents a locally grown.”
Breaking bombs on sea food
Toon to Billet, the highest sand dumping audience in Europe, is already walking on paths made with this oyster -based concrete, which is available at a distance of 20 kilometers from that place. The 100 -mereters of catwalk, which receives millions of tourists every year, is the right place to prove the life of the object in serious situations.
“We have a true circular economic approach by recycling the waste produced in this area, which helps the public highlight this approach because this place is very popular among the audience,” says Professor Gracoire.
The group now expands its tests to the most difficult environment. On the French Atlantic coast, in the historic Puerto de Zokova, they are experiencing with low carbon motor, which contains processed oyster bombs to strengthen the centenary stone walls of the port.
It is not a trivial task to create a combination of severe coastal conditions. “With high waves, the water level will be above me, so the material will sink in two or three hours. The following waves must be set up at that time to resist,” Professor Grakoir explains.
There is still growing trusty applications. In the Internetal Zone, located behind the seventeenth century fortress of Sokova, researchers have dozens of small concrete blocks made with oyster tiles to examine how the sea life is communicated with these materials.
“If this new biological concrete has a significant colonial – equivalent or better than the natural substrate – we can conclude that there may be a benefit to the use of this concrete.” This is like an external mini -laboratory, ”says Elsa Pianelo, a biologist who works in the project.
If they succeed, these products can become a synthetic reef construction blocks, which are favorable to marine biodiversity, while helping to protect the rise of itching and sea level.
Net heritage
In the meantime, the Spanish Mediterranean coast, the old fishing nets charge a second life for a project funded with the European Fund. In Kandia, the company’s gravitational wave is related to collecting rejected networks with local fishermen, otherwise, the sloping of a landscape or sea will end.
“This is a very criticized field, so whenever you approach them, there is a good mood to be part of the solution,” says Ignacio Marte, responsible for the general problems of public resources and gravitational waves.
These durable marine plastics are characterized by waterproof, sun resistance and significantly durable solid plates. The finished product includes design office tables, street banks and stadium seats.
“When they realize that the coating directly creates this connection with this turquoise or sea -like sea -like sea that takes you directly to the sea,” says Mary Haro, responsible for the gravitational wave supply and circular economic chain.
From oyster shells to fishing networks, European researchers are turning marine waste into tomorrow’s bricks.
