Wastewater treatment plants as biorefineries: the RoKKa project

RoKKa, a joint project coordinated by the Fraunhofer IGB, is testing methods for recovering raw materials such as phosphorus and nitrogen compounds to produce fertiliser from municipal and industrial wastewater in a climate-neutral way. These new methods are being investigated under real conditions at wastewater treatment plants in the Ulm area with a view to developing them into sustainable biorefineries.

InBiRa: Insect biorefinery turns food leftovers into new products

Insect larvae can convert food leftovers and waste into secondary raw materials for technical products and cosmetics. Researchers are looking to establish an insect biorefinery for this purpose at the Fraunhofer IGB in Stuttgart. The InBiRa project is financed with a total of 3.8 million euros in EU and Baden-Württemberg state funding.

The Ministry of the Environment, Climate Protection and the Energy Sector is funding the KoalAplan project, which extends the functional scope of a wastewater treatment plant. The project, based in the Stuttgart district of Büsnau, aims at recovering raw materials from wastewater and is therefore making a positive contribution to climate neutrality, as the products obtained replace fossil raw materials and energy-intensive processes.

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…

Making important raw materials for fine chemicals out of carbon dioxide really works. As part of the Max Planck collaborative project eBioCO2n, a team of researchers from Fraunhofer IGB have successfully performed a first ever fixation of CO2 via a multi-enzyme enzyme reaction driven by electricity yielding a prospective intermediate for the chemical industry. The process for electro-biocatalytic CO2 fixation was recently published and is…

Climate-friendly circular economy - 11/11/2021

CO2 from the air as a raw material for chemicals

A Fraunhofer team has successfully produced a dye using CO2 adsorbed from the air. The aim is to move towards a climate- and resource-friendly circular economy. Chemicals, as well as fuels, can be produced cost-effectively using this process. How does the technical process work, and what opportunities does it open up?

Carbon dioxide is one of the main drivers of climate change – which means that we need to reduce CO2 emissions in the future. Fraunhofer researchers are highlighting a possible way to lower these emissions: They use the greenhouse gas as a raw material, for instance to produce plastics. To do this, they first produce methanol and formic acid from CO2, which they convert via microorganisms into building blocks for polymers and the like.

The amount of plastic waste increases every year. Some of this waste is due to plastic packaging used to protect food. As part of the “BioActiveMaterials” project, researchers at the Fraunhofer-Gesellschaft have developed an eco-friendly coating for paper packaging. With this, not only is plastic saved, but the coating of plant-based proteins and waxes also extends the shelf life of the food.

Textiles can be coated with the biopolymer chitosan and thus made water-repellent by binding hydrophobic molecules. The good thing is that this can also replace toxic and petroleum-based substances that are currently used for textile finishing. In the last few years Fraunhofer IGB and partners have developed technology to provide fibers with the desired properties using biotechnological processes and chitosan.

The wastewater treatment plant is turned into a vegetable farm, bio-based substances recovered from waste are being utilized to prevent oxidative spoilage in food packaging or provide environmentally-friendly and safe water-repellent coatings on functional textiles. In the EVOBIO project coordinated by Fraunhofer IGB, 19 Fraunhofer Institutes are working on solutions for a sustainable economy.

Germany generates around 38 kilograms of plastic waste per capita each year. Researchers from the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and the Fraunhofer Institute for Process Engineering and Packaging IVV are now working to establish a holistic concept for the sustainable use of biologically degradable packaging materials in the cosmetics industry. The project is focusing on polyhydroxyalkanoates (PHAs).

Time for climate protection is pressing. One approach to tackle this challenge is to use the greenhouse gas CO2 as a raw material for chemicals. The researchers of the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB, together with partners from science and industry, were able to produce a value-added terpenoid dye from CO2 adsorbed from air by a combination of electrochemical and biotechnological conversion.

Producing valuable new products from waste materials - 07/01/2020

A vision: insect biorefineries as components of a sustainable bioeconomy

Eco-friendly and responsibly manufactured products are more in demand than ever before. Specific research is being carried out into materials and applications for a wide variety of uses. The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB is working with Hermetia Baruth GmbH on the vision of an insect biofactory that uses waste materials to produce a wide range of products such as biosurfactants, animal feed or foils.

How can we achieve the internationally agreed climate targets? The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB makes the greenhouse gas CO2 usable as a carbon source for the chemical industry. With a patented catalyst synthesis, screening for the optimal catalyst in high throughput and combined (electro)chemical-biotechnological processes, various concepts are available to CO2 emitting industries.

Textiles: water-repellent thanks to fungal proteins

Outdoor lovers and athletes love them: water-repellent jackets and trousers. However, many consumers are unaware that the chemicals used to functionalise the textile surface often pollute the environment. Organic fluorine compounds (perfluorocarbons = PFC) are usually added to textiles to make them water-repellent. Scientists at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and the Hohenstein Group are researching an…

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…

Energy generation from waste

We are all very aware of what happens when we dispose of waste whether it is industry waste private household waste or CO2. We also know that cost-effectiveness is still given priority over sustainability. As more and more waste is dumped it is increasingly entering the groundwater soil and atmosphere. The ideal solution would enable us to kill two birds with one stone if we could somehow combine the problems related to increasing environmental…
