Biological carbon sequestration is the storage of atmospheric carbon in vegetation, grasslands, woody products, and oceans. By encouraging the growth of plants, particularly larger plants like trees, biological sequestration removes CO2 from the atmosphere. Thisincludes reforestation, but also enhanced use of fast-growing perennial plants that are then turned into useful materials, e.g. building materials such as bamboo or wood or other carbon negative materials such as bioplastics.
Reforestation is important, and needs to be done on a global scale. But interms of capturing carbon from the atmosphere, this is generally a slow process. By utilizing fast-growing crops that are then turned into useful materials, the process of removing carbon is faster, and carbon negative materials may prove to be key in the future, where every produced material ultimately needs to be sustainable.
