Carbon Negative Hemp Concrete

Tradical Hemcrete is a bio-composite, thermal walling material made from hemp, lime and water. What makes it carbon negative? There is more CO2 locked-up in the process of growing and harvesting of the hemp than is released in the production of the lime binder. Of course the equation is more complicated than that, but Hemcrete is still an amazing new technology that could change the building industry.

Who says you can't build schools with hemp? Thanks Roaldgold!
