Researchers at Rensselaer Polytechnic Institute (RPI) in the United States have developed a hemp-based alternative to steel rebar. Researchers believe that the new option can avoid corrosion while reducing carbon emissions from construction, according to a report published by Dezeen.
Hemp rebar can be used to hold concrete structures in the same way as steel and other currently used rebars, but with a lower environmental impact because of its longer lifespan and hemp’s effectiveness at sequestrating carbon dioxide.
