| BioBTX | Aromatics are very important chemical building blocks for a wide range of important materials. BioBTX replaces oil for biomass & waste as a resource for the production of aromatics and thus enables the production of sustainable materials. BioBTX developed a unique and commercially attractive integrated catalytic pyrolysis process thatmaximizes BTX yield and minimizes operational costs. Without biobased aromatics the options for sustainable materials are very limited; with biobased aromatics however, it is possible to achieve truly green materials for our society. We want to change the world; we want to make our future green. This is why we develop technology for the production of biobased aromatics. | $45.8M | Venture - Series Unknown | Jun 03, 2024 |  |
