Hempcrete, a.k.a. hemp concrete or lime hemp concrete is one of the 25,000 applications of the miraculous hemp plant. It is a light-weight material that was hitherto used only for non-structural purposes or as an in-fill material for timber-stud walls. The material is used widely in E.U. for its superior thermal comfort, light weight, hygrothermal behaviour and energy efficiency. Another hallmark feature of hempcrete is its carbon-negativity. Being a bio-aggregate material, hempcrete has the capability to store carbon dioxide. It has been proven that hemp + pure lime has the capability to store approx. 700 kg of CO2 per cubic metre of hempcrete, which is more than even the self-weight of the product! Hempcrete is also resistant to decay, mold, insects and rodents. It has been used in Ellora Caves to preserve paintings from decay. Amazingly, hempcrete also gains strength with time, improving its durability.
