Material 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.
BIOMATBIOMAT 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.COLUMBUS, OH
Sustainable CompositesRooted in Lancaster County, Pennsylvania, Sustainable Composites upcycles discarded leather scrap into reusable material that can replace traditional leather in products such as luggage and furniture.
