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.

As publishers of HempBuildMag.com, we are excited to bring a new and updated edition of the Hemp Building Directory for 2025. 

We are watching the industry grow and expand in this  comprehensive directory of the international hemp building industry in 2025. Our listings cover more than 700 unique companies and experts in 32 different countries in 26 categories.
