One of my favorite site is Inhabitat- It is one of the top sites for green building and design. Here is one of their posts on Hemp Walls:
Buildings account for thirty-eight percent of the CO2 emissions in the U.S., according to the U.S. Green Building Council, and demand for carbon neutral and/or zero footprint buildings is at an all-time high. Now there is a new building material that is not just carbon neutral, but is actually carbon negative. Developed by U.K.-based Lhoist Group, 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. Read the full articles here…
