At this year’s Greenbuild Conference and Expo, held Nov. 4–7 in Los Angeles, bio-based building materials took the spotlight — both on the show floor and in one of the conference’s most crowded sessions.

International and US experts in hemp-lime construction gathered at the Lower Sioux Community in Morton, MN to celebrate hemp-based building materials at the 13th Annual International Hemp Building Symposium this month. Co-hosted by the Ireland-based International Hemp Building Association (IHBA) and the Lower Sioux Hemp Program, the event featured both scientific research and practical applications of bio-based building materials.

On a chilly Pacific Redwoods morning in April, Joann Kerns, 68, was perched on her garage roof in Eureka, CA filming a crane installing the first 2,000 lb. wall panel for her new hempcrete ADU (accessory dwelling unit) when the operation took a surprising turn.

Homeowners returning to their burned-out homes in southern California are facing the painful consequences of the US construction industry’s reliance on cheap plastics and petroleum-based building materials: Not only are these materials easily combusted in a wildfire, but they leave behind a toxic soup that has polluted waterways and poisoned air quality.

We’re sticking out our neck at HempBuild Mag and trying to predict what will happen in the wonderful and confusing hemp building industry  in the new year.
