Multiple US hemp-building companies will make a big splash for around 25,000 visitors at one of the largest US construction sustainability expos and conferences later this month in Philadelphia, thanks to collaboration and the generosity of a hemp processing company and a hemp-building non-profit.

Hemp building materials were featured at the SXSW Climate Change conference March 11 in Austin, TX, and the hemp building community came together to raise money to build refugee hempcrete housing in Ukraine.

Hemp-based construction companies have been knocking on the door of events like San Francisco’s Greenbuild Expo for years. But this year, three companies presented their products and networked with the many designers, builders, architects, engineers and city officials attending.
