Though hempcrete is healthier for both a building’s occupants and the planet, high costs and lack of research stand in the way of widespread acceptance.
Hempcrete, a building material made from the woody core of the hemp plant, could revolutionize sustainable architecture and engineering. If, that is, we can overcome a number of frustrating barriers that stand in the way of widespread implementation.
Made from just a few simple ingredients (often just hemp hurds, water, and lime), hempcrete is resistant to numerous hazards, including pests and fire. Hempcrete buildings even become carbon-negative over time as the walls absorb the carbon dioxide that’s exhaled by occupants.
