TU Delft self-healing bio-concrete nominated for European Inventor Award

News - 21 April 2015

Researcher Henk Jonkers from TU Delft and his bio-concrete have been nominated for a European Inventor Award, an initiative of the European Patent Office (EPO). 


Building with concrete that is able to heal itself? It might seem like a far cry, but if microbiologist and inventor Henk Jonkers from the TU Delft has anything to do with it, this will soon be reality. This Dutch researcher has developed the bio-concrete of the future, inspired by nature: concrete with bacteria embedded in it. 
Jonkers: ‘What makes this limestone-producing bacteria so special is that they are able to survive in concrete for more than 200 years and come into play when the concrete is damaged. For example, if cracks appear as a result of pressure on the concrete, the concrete will heal these cracks itself.’ 
Numerous applications are possible for this invention and it has currently been translated into three products to be launched on the market this year: self-healing concrete, repair mortar and a liquid repair variant. 



Henk Jonkers and his bio-concrete of the future have now been nominated for a European Inventor Award, an initiative of the European Patent Office (EPO) (including a short film). The tenth edition of this event, at which the Inventor Awards will be presented, will take place in Paris this year. Benoît Battistelli, the president of the EPO, says the following about the Jonkers nomination: ‘This innovation is clearly looking towards the future. Bacterial concrete will extend the service life of bridges, streets and tunnels and give a completely new perspective to concrete production.’
