Lower Sioux Building First US Hempcrete Production Facility.

The Lower Sioux Indian Community in Minnesota is building the first hempcrete production facility in the United States. The community plans to use hempcrete, a construction material made of lime, hemp, and water, to build homes for its members. Hempcrete has been used as a building material abroad for decades but was not permitted in the US until the 2018 farm bill legalized industrial hemp production. Hempcrete is lightweight, self-insulating, nontoxic, and resistant to mold, fire, and infestation. It also has the potential to absorb CO₂ during its growth phase. Efforts are underway to get hempcrete approved for use in commercial construction. [Extracted from the article]
