US: Hempitecture has inaugurated a hemp-based insulation plant in Jerome County, Idaho. The plant employs five people and produces insulation using hemp grown in Montana. The producer hopes to supply its flagship HempWool thermal insulation and other acoustic and continuous insulation products to major green building materials markets, including Denver, Los Angeles and San Francisco. It began developing hemp-based insulation in partnership with the University of Idaho with a US$207,000 grant from the Idaho state government in 2021.

Hempitecture CEO Mattie Mead said "We are ushering in the future of truly sustainable building materials."

US: Knauf Insulation is celebrating the 20th anniversary of the beginning of operations at its Shasta Lake glass wool insulation plant in California. Local press has reported that the company increased its capacity by 70% over the past two decades. Today, the Shasta Lake plant employs 156 people. It has implemented sustainable practices in its production, including the use of ECOSE Technology plant-based binders in the place of petrochemical alternatives. It also recycles 600,000 glass bottles daily, constituting 50% of its glass consumption. This presented the plant with difficulties when Covid-19 lockdowns reduced local waste glass generation.
