Sustainable carbon black production from Swedish forest material

Carbon black is one of the world's most useful chemicals and is used e.g. to increase wear resistance in rubber, as a black pigment or as a material in various electronic applications. Carbon black is today produced exclusively from fossil raw materials. The main objective of this project is to replace the fossil raw materials with renewable products from the forest, as well as to use electrofuels (hydrogen or plasma) for the heating of the process, in order to contribute to the sustainable production of carbon black. In order to succeed in this, we need to generate new experimental knowledge for how different renewable raw materials, as well as electrofuel exhaust, affect the yield of carbon black and its material properties. Based on the product's material properties, suitable areas of use are evaluated at the same time that techno-economic calculations give the answer to the most profitable alternative from an industrial point of view. The bio-based value chain is then compared to traditional carbon black production from a sustainability perspective.
