London-based design consultancy and materials library Material Driven has published an excellent piece with one of the most succinct explanations of the Made of Air material and how it is produced that we've read:
"In the context of climate change, and the growing awareness that the building industry contributes heavily to global emissions–the process of creating concrete alone accounts for an estimated 5 percent of human-caused carbon dioxide (CO2) emissions annually–there has been tremendous momentum to create carbon-negative materials and products. From green cement to substitutes for wood-based particle boards, to advanced self-healing materials (which either reduce CO2 generated over their lifetime or sequester it for their healing process)–carbon negativity is the motto of the day in architecture and construction."
"One such carbon negative material–tangible, scalable, and versatile–is Made of Air. The radical and new biochar-based material is robust, thermoplastic, and is composed of 90% atmospheric carbon. The dense, smooth, fire-retardant material presents itself as a sustainable alternative for use in construction, interiors, furniture and more."
"The starting point for Made of Air is waste biomass. Biomass is an organic material which comes from plants and animals. Throughout its lifetime biomass absorbs CO2 from the atmosphere, as well as sunlight, storing energy from the sun. Transforming this absorbed, fixed CO2 into a useable form is the next step. This waste biomass is baked to a stable form of carbon by pyrolysis, in an oxygen-free oven environment. This form of carbon is then mixed with a biodegradable binder to yield a moldable and carbon negative material. After being shaped into products for building facades or interiors, at the end of its lifecycle, the material can be shredded and sequestered in the earth. This cycle can be repeated continually, allowing for more and more atmospheric carbon to directed to the earth."
