Title: Carbon-Enhanced Manufacturing Supporting Recycling of CO2


Biography: Dominik Rohrmus


Climate change requires answers beyond the pure optimization of resources consumption and energy demand management in areas like manufacturing. CO2 as a supply for new synthetic raw materials and products as well as markets is a long-term approach to establish a green cycle economy. We define green cycles as CO2 sinks. The Siemens green cycle vision for green production and green raw materials opens new manufacturing models and new product markets to provide an answer for the world’s hunger for materials. These materials have a promising future for non-food related components such as electronic parts. Green cycle factories apply the concept of green cycles to the discrete manufacturing industries. The prerequisites are CO2-neutral forms of renewable energy as well as chemistry production technologies, which are synthesizing fuels and materials for manufacturing from CO2 sources which then yield the recycling of CO2. One economic driver is the merging of different energy grids. The focus lies on renewable supplies that fulfill the demands of future manufacturing technologies in terms of additive manufacturing processes which are mainly using carbon materials coming from renewable, biodegradable resources. The transformation process requires new manufacturing systems in a decentralized and mostly digitalized manner. A new additive manufacturing process based on this carbon feedstock is one promising application field with the advantage to transfer the CO2 load into discrete products. Hence, low carbon in the atmosphere can be realized by green cycles, i.e. CO2 recycling and advanced carbon-based materials and manufacturing.
