A century traditional Australcher faces a hidden challenge on the French coast. Every succulent oyster that reaches our foods and the other does not survive. There is an empty shell that creates the waste mountains that farmers are managed. With the mortality rates that reach 50-90% of some crops, these rejected bombs represent both environmental load and unleashing resource.
Professor David Grakoire and his research team of the University of PAU and Base de Shore transform this marine waste into the construction of the future.
“If we look at the beaches around the world, we will find sea bombs used to make concrete in Senegal, Morocco and many other coastal areas,” Professor Grakoir explains. “The bombs have long been the raw material in traditional construction.”
However, what distinguishes your research is that it completely replaces regular sand and gravel crushed oyster shells, which is the most unusual approach to modern construction.
The science behind this discovery is astonishingly simple. Austra bombs are biomedically made of mallus, which is basically a natural limestone stone that is calcium carbonate. It makes chemically similar with traditional construction, but with unique advantages.
This concrete with shells simultaneously faces many environmental challenges, which begins with the fall of quarries. As Professor Grakoire points out: “We need to retain resources because we do not need regular sand and shortage around the world.”
The benefits are beyond the safety of resources. By attaching these shells with low carbon cement, the resulting concrete often reduces co₂ emission compared to regular production methods.
Another possible advantage is currently tested. “Our material provides more biomanism,” says Grakoire, which is suitable for marine applications, such as favorable regeneration of environmental systems.
Innovation already demonstrates its performance in real applications. Visitors of Europe’s highest sand dune bill, now walking on this oyster -based concrete routes, opposed the use of serious pedestrian use for many years.
This work not only solves a waste problem, but also to create a circular model, in which the waste of an industry will become the bricks of another.
