    Microalgae - high-quality products for domestic agriculture?

    Algae are aquatic organisms that flourish in a huge variety of species. But that's not all: they are also small green mini-factories that can produce all kinds of valuable materials. All they need is water, light, CO2 and a few nutrients that can be recycled from biogas or sewage treatment plants. Researchers have now determined the optimal framework conditions and practicability of process methods for agricultural algae cultivation.

    Valuable materials of all kinds - produced automatically in living cells

    In future, algae could be used to produce practically everything that still requires petroleum, including plastics, fuels, medicines and food. Algae are also climate savers par excellence, because they bind ten times more CO2 than terrestrial plants. Festo, a company based in Esslingen, Germany, has developed a high-tech bioreactor that can be used to automatically cultivate the small green biofactories - and that do so a hundred times more…

    Algae as microscopic biorefineries

    Fossil raw materials are limited and not available and extractable everywhere in the world – as we are becoming acutely aware of right now by the example of fossil fuels and rising energy prices. Renewable raw material sources will therefore play an increasingly important role in the future: as energy sources, but ideally also as suppliers of building blocks for more environmentally compatible chemicals and materials.

    Pilot project RoKKa uses wastewater to produce fertiliser and raw materials

    The Ministry for the Environment, Climate Protection and the Energy Sector is funding the new research project RoKKa which is used to prove the viability of recovering raw materials from wastewater. This adds a crucial function to the scope of a conventional sewage treatment plant. Together with the operators of the sewage treatment plants in Erbach and Neu-Ulm, the project partners demonstrate the positive contribution towards climate protection…

    The REDWine project and climate change

    In the EU project REDWine, the CO2 produced during wine fermentation is captured and used to produce algae biomass. Novis GmbH from Tübingen supplies the complete system for CO2 utilisation. The aim of the project is to reduce the share of global warming caused by wine production in a way that is economical for producers.

    Magnetised algae as microrobots for medical and environmental purposes

    Algae, for most of us, is something that lives in water courses that we occasionally find unpleasant. However, that is to do them a wrong. These extremely versatile and frugal organisms might in future prove to be extremely important. Scientists at the University of Stuttgart are investigating how algae can be used as microrobots in biomedicine and environmental remediation.

    Residues from biogas plants as feed for algae

    Algae are frugal organisms. They require only light, water, minerals and carbon dioxide to be able to produce biomass. These properties will now be exploited economically in a two-year research project. Dr. Stefan Sebök from the University of Hamburg plans to study the holistic utilisation of degradation products of a biogas plant in Wallerstädten by linking them to land-based algae cultivation.

    Perspectives on the bioeconomy

    The sustainable economic system known as the bioeconomy is based on two main pillars: the use of renewable raw materials rather than fossil raw materials, and biobased innovations. The aim of the bioeconomy is therefore not only to replace fossil raw materials, but also to develop completely new products and processes. In so doing, it contributes to and creates the conditions for a closed circular economy. Baden-Württemberg has the skills…

    Biomass from algae and the wholesale market – a promising replacement for fossil raw materials

    Funding renewable energies is one of the EU’s key objectives. Biomass such as algae and organic waste are particularly promising because they are not in competition with food production. Scientists at the Fraunhofer IGB in Stuttgart ferment biomass from wholesale market waste and algae. They use a cascade process to obtain valuable materials and the biogas methane. Their aim is to close material cycles and achieve high efficiency and flexibility…

    Biogas from unicellular green algae

    Microalgae are among the most promising sources of sustainable, carbon-neutral biofuels for the future. They are already being used as feedstock for producing biogas, biodiesel, bioethanol and kerosene, but the associated production methods consume a great deal of energy and are rather costly. Dr. Nikolaos Boukis from the Karlsruhe Institute of Technology (KIT) is working on the development of a sophisticated, thermochemical process with an…

    Producing chemicals sustainably using microalgae

    Many chemicals in lubricants and washing powder are produced from fossil fuel. However, as fossil fuel is limited and reserves are slowly but surely running out, finding suitable substitutes is essential. This is the only way to ensure that much needed working materials continue to be available in the future.

    Ioanna Hariskos: Biogenic calcification as a role model for industry

    Emiliania huxleyi, a calciferous microalga of global importance, is one of the major calcite producers in the world’s oceans. It forms calcium carbonate discs that are barely discernible under a light microscope. This biogenic calcite differs from fossil calcite primarily by its filigree three-dimensional structure. Ioanna Hariskos and other scientists from the Karlsruhe Institute of Technology (KIT) produce highly complex biogenic calcite…
