Is the Rhine-Main-Neckar Greentech Ecosystem prepared to support start-ups along the entire development process from the ideation to commercialization? The developments of novel products and services required in Greentech, specifically in the deep technology sectors of chemistry, green and white biotechnology, and material sciences requires extensive infrastructure. This includes dedicated laboratories, technical equipment, and scale up options like pilot plants, the establishment of which requires cost intensive investment. In chemistry and biotechnology, besides the technical challenges, the regulatory aspects pose a major barrier to the success of start-ups at a certain development stage (Technology Readiness Level [TRL]) and are thus identified as key hurdles for funding new businesses. These and similar hurdles can be addressed while bringing an idea to fruition in a Greentech environment since such ecosystems allow for parallelization of workflows for multiple projects, taking advantage of centralized functions and expertise. In the Rhine-Main-Neckar [RMN] metropolitan area, a united approach from politics, academia, transfer units and technology hubs, accelerators, and industry is being put into place to offer start-ups a tailormade Greentech environment to grow ideas that are urgently required to create a more sustainable economy and combat the climate crisis.
