In the Netherlands, Corbion has launched a renewable copolymer for adhesion or controlled release. Dubbed SENTIALL, one of the first applications being pursued is self-healing concreate developed jointly with Delft University spin-out Green Basilisk.
According to Corbion, a team at TU Delft found a way to manufacture a bacteria that, when exposed to oxygen and water, would fill cracks by converting substrates into limestone. By repairing cracks automatically, the durability of concrete structures can be improved while reducing maintenance and repair costs.
“SENTIALL technology offers game-changing functionality in a number of industries,” says Frederik Feddes, vice president Biochemicals at Corbion. “Our collaboration with TU Delft in the development of an enormously important innovation like self-healing concrete shows the kind of innovation this platform makes possible.”
