Kajima said the company has developed a technology to artificially grow algae that grows in waters around Japan.

According to company representatives, he managed to multiply a single algal cell hundreds of times and then planted the seedlings in waters south of Tokyo.

Carbon sequestration in coastal ecosystems, known as blue carbon, is gaining attention as a way to advance decarbonization.

In Japan, coastal seagrass thickets have been reported to be decreasing due to backfill work and rising seawater temperatures.

“Our firm is a construction company. That means we have to work ecologically. Blue carbon is one way we contribute,” said researcher Yamaki Katsunori from Kajima.

He says the company will work with fishing cooperatives and nonprofits to restore algae beds based on research results.

As reported by Ukrinform, Japanese researchers claimed to have discovered phytoplankton in Arctic waters that can produce and accumulate a substance similar to that found in gasoline and diesel fuel.
