Joint project: PARNES
Tires are indispensable elements of mobility. Because of their unique properties, they are produced out of rubber. Other organic materials (e.g., carbon black or oils) are added to the rubber while mixing the different components. During the mixing process volatile organic components (VOCs) can be produced along a mixer line and further processing (e.g., tire curing presses). Since there is currently no known material that can replace tire rubber, it is necessary to minimize the emission of VOCs during tire manufacture as far as possible. The task of the project applied for funding is the development of a sustainable and resource-saving treatment of exhaust gases containing VOC. The technologies used to date (regenerative combustion, possibly with prior concentration of the exhaust gases) do not meet these requirements. Not only do they cause direct carbon dioxide emissions using fossil fuels, they also prove to be operationally disadvantageous or vulnerable in industrial practice. The approach applie d for funding is process-integrated, uses material flows that are already used in the mixing process as adsorbents, does not require fossil fuels and avoids the operational problems of previously used technologies. With the process, the costs for energy and CO2 certificates, for example, can be significantly reduced.
