Carbon Zero - 10 Examples of materials that store atmospheric carbon

01

Bioplastic

German brand Made of Air has developed a carbon-negative bioplastic that can be used in cars, interiors, and cladding. The material contains biochar, a carbon-rich substance obtained by burning biomass without oxygen, which prevents carbon from escaping as CO2.

02

Mycelium

Some startups, including London-based Biohm, are using mycelium to create building insulation that is naturally fire-resistant and removes “at least 16 tons of carbon per month” from the atmosphere. Mycelium, the biomaterial that forms the root system of fungi, feeds on agricultural waste and, in the process, captures the carbon that is stored in this biomass.

U.S. carpet tile manufacturer Interface is aiming to make its entire product range carbon-negative by 2040, starting with the Embodied Beauty and Flash Line models, which were released in 2021. They are made almost exclusively from recycled plastics and various biomaterials.

04

A fully grown tree can remove 22 kilograms of CO2 from the atmosphere in a year, meaning that this material is carbon negative if sourced responsibly, and the felled tree is offset by new planting.

Wood

05

Household goods company Forust has developed a way to convert sawdust and the natural polymer lignin emitted by the timber and paper industries into 3D printing filament.

Olivine, which is one of the most abundant minerals on Earth, is able to absorb carbon when it is crushed and scattered across the earth.

07

Montreal-based Carbicrete has developed a type of concrete that captures carbon during production, replacing emission-intensive cement that accounts for 8% of all greenhouse gas emissions from the steel industry.

08

Australian company Mineral Carbonation International injects CO2 into industrial wastes such as mine waste, turning it from a gas into a solid that can then be used to make cement bricks and other building materials.

Solar Foods is among a growing number of companies using industrial emissions to produce food and beverages.

Brooklyn-based Air Co uses CO2 to produce vodka. The brand breaks down carbon dioxide using water and a patented catalyst in a reactor to create ethanol, which is then used to distill vodka.
