This means it lends itself to being a fertiliser and a replacement for sand or gravel in landscaping, while the carbonated version (above) can be used as an additive in the production of cement, paper or 3D-printing filaments.ĥ. Olivine, which is one of the most common minerals on earth, is capable of absorbing its own mass in CO2 when crushed and scattered on the ground. They are constructed almost exclusively from recycled plastic and various biomaterials, which the brand says store more embodied carbon than is emitted by the products in their production.Ĥ. American carpet-tile manufacturer Interface is aiming to make its entire product range carbon negative by 2040, starting with the Embodied Beauty and Flash Line carpets that were released this year. Mycelium, a biomaterial that forms the root system of fungi, feeds on agricultural waste and in the process sequesters the carbon that was stored in this biomass.ģ. Start-ups including London-based BIOHM are using mycelium to create building insulation that is naturally fire-retardant and removes "at least 16 tonnes of carbon per month" from the atmosphere as it grows. The material contains biochar, a carbon-rich substance made by burning biomass without oxygen, which prevents the carbon from escaping as CO2.Ģ.
German brand Made of Air has developed a carbon-negative bioplastic that can be used in cars, interiors and cladding. 10 materials that store carbon! Here are some of my favorites, from the Dezeen article.ġ.
