“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 car”bon 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.”

wow. that is insane. i saw this other new type of concrete called “hebel” — aerated concrete. it is really easy to bandsaw and even handsaw so, you can cut it to the exact size you need (which normal concrete makes impossible). it is also lighter to ship, easier the handle, etc.
i actually have a sample block of it, if you ever want to see it just let me know.
