Amazing Lego-Style Hemp Blocks Make Building a House Quick, Easy & Sustainable

These hempcrete blocks are a green building material made with a hemp-lime insulation mixture packed around a biocomposite structural frame. They can be stacked like bricks to build walls up to 30 feet high and they become the insulation and the structure of the building. All you need to do after the walls are built is plaster the inside and outside, and then add windows, doors, and a roof!

The hemp plant sequesters carbon during its growth, and lime, as it dries, reabsorbs the carbon that was released when it was manufactured, which means the hemp-lime mixture is carbon negative (it sequesters more carbon than it creates in its life cycle). Terry Radford from Just BioFiber says that these hempcrete blocks will sequester about 10 tons of carbon per house.
