Jacob Waddell is the president of the Hemp Building Institute, a nonprofit organization dedicated to researching and promoting healthy and sustainable building practices. The way we construct our built environment has been a major cause of today’s most pressing environmental and health problems. Moving away from conventional construction materials to those that are more natural is a promising solution that’s only now starting to catch on in the U.S. 

Jacob and show host Neil discuss Jacob’s path to working with hemp, including his time studying material science and working with plastics before he had a revelation that he should dedicate his life to the environment. It was at that time that he discovered hempcrete—a construction material made by mixing hemp stalks and lime as a binder. They also dive into the environmental, health, and sustainability benefits of hemp building materials, including how it can be “carbon-negative,” improve indoor air quality, and improve soil quality. Now the challenge is making hemp construction mainstream and affordable, so everyone can share in its benefits. For more information about Jacob’s work, visit hempbuildinginstitute.org.
