BIOMAT makes renewable, carbon-negative building materials from hemp and lime, including precast interlocking panels for healthier, more energy-efficient walls. Its hemp-lime material is designed to resist fire, mold, pests and moisture while capturing carbon in the building envelope. Made from hemp, lime and water, the panels offer a natural alternative to traditional stud construction.
Ouros MaterialsOuros Materials is an early-stage materials technology startup developing composite building panels that mineralize captured CO₂ during curing. Its low-temperature process combines ceramics and polymers to make panels designed to be fire-resistant, durable, and easier to machine, while using renewable energy and targeting lower costs than premium alternatives. The company is moving from university research through pilot production, with interior and exterior panels still in the prototyping phase.
Material MaximMaterial Maxim is a collective of specialists organized around the idea that the built environment can become regenerative rather than extractive. It helps global brands and other businesses rethink material lifecycles and develop practical routes toward circularity, using hemp-based solutions as one way to connect carbon reduction with new manufacturing systems.ONEONTA, NY
HempWoodFrom its Murray, Kentucky operation, HempWood manufactures hemp-based composite lumber and building materials, including flooring, panels and furniture components. The company began mass production and order fulfillment in the third quarter of 2019, turning fast-growing industrial hemp into a wood substitute for interior design and construction. Its products are made in the United States and include non-toxic, no-VOC options supported by documented material and safety testing.EDGEWATER, MD
