Hempcrete, which sounds rather like a made up hippie word instead of an alternative building material, is a fascinating green construction option that uses the hurds, or inner woody core of the hemp stalk (as opposed to the bast fibers, which are used for textiles and cordage), in a mineral matrix, to form a non-toxic, carbon - negative, and energy - efficient material.

GreenBuilt searched for a healthy, durable, climate resilient material that could provide high - quality permanent housing as well as temporary shelter, and hempcrete (a bio-composite made of the hemp plant's inner woody core combined with a lime - based binder) appeared to be a superior option because of its sustainability and carbon sequestration properties, as well as its potential to spur economic development.
