Cool Roof France has found an innovative way to use the 130,000 tonnes of waste oysters produced every year in France.
As heat waves continue to scorch Europe, many of us are looking for cheap and innovative ways to keep our homes or workplaces cool.
While air conditioning often proves effective, its environmental cost contributes further to the climate crisis.
So what if we look into the past and to other parts of the world for inspiration and start painting our roofs white?
“This technology is just pretty old actually, but this is quite innovative to make it so technical,” says Julien Martin Cocher, deputy CEO of Cool Roof France.
But does having a white roof really make a building cooler?
Cool Roof France (CRF) is on a mission to reduce the ambient temperature inside buildings in a sustainable and cost effective way.
Traditional paint is made up of calcium, solvent and water.
“The oyster was at the beginning just to use a waste that we are finding quite easily in the west part of France and to replace this calcium that we are usually finding [in paint],” Julien explains.
Its innovative team of scientists soon discovered that the oyster shell maximises the paint’s performance and makes it more durable.
