Refuels are renewable fuels that can be produced in different ways. When they are mixed and processed such that they meet the existing fuel standards, they are suited for all types of combustion engines. This is the result of the latest vehicle and fleet tests within the project “reFuels – Rethinking Fuels” at Karlsruhe Institute of Technology (KIT). Compared to fully fossil fuels, refuel mixes allow for a CO2 reduction by 25% at least. Moreover,…

The EU funded research project HyFlexFuel recently succeeded to produce biocrudes via hydrothermal liquefaction (HTL) from a variety of biomasses, including sewage sludge, food waste, manure, wheat straw, corn stover, pine sawdust, miscanthus and microalgae in a pilot-scale continuous HTL plant at Aarhus University (Denmark).

Microorganisms are the oldest, most abundant, and most diverse life forms on earth and offer enormous potential for biotechnological applications. To date, however, only a fraction of them could be isolated and cultivated. The “MicroMATRIX” research project, funded with € 1.5 million by the German Federal Ministry of Education and Research and led by Karlsruhe Institute of Technology (KIT), aims to shed more light on the microbial darkness.

The final report including comprehensive fact sheets of 25 applications is now available online in German and English.

From being thrown away to becoming a recycled product - Stuttgart start-up produces healthy snacks

Throwing away food? The Stuttgart-based start-up Zero Bullshit Company is declaring war on food wastage by making nutrient-rich products largely from food industry leftovers. The three food technologists who created this transparent brand are looking to develop more than just delicious and nutritious products.

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.

Freiburg researchers have studied how changing their diet could influence the ecological footprint of Germans.

Population growth and the increasing standard of living make our society face big ecological challenges: Climate change, littering of the seas, dwindling agricultural areas, resource scarcity. Bioeconomy aims at replacing fossil by regenerative resources and at using advanced and sustainable technologies based on biological knowledge and principles.

The BioSinn project found products and applications for which biodegradation at the end-of-life is a real option. 25 fact sheets answer technical and regulatory questions for each application. The market volume of these applications was also estimated: in Germany it is about 170,000 tonnes, in the European Union about 1 million tonnes per year!

Protecting the global climate is an undertaking that presents both industry and society with a major task. It will not be possible to achieve the climate targets simply by limiting global emissions, by saving carbon dioxide (CO2). This is because there will continue to be unavoidable CO2 emissions that will nevertheless have to be compensated.

European project with participation of the University of Hohenheim investigates how unprofitable fields can be used sustainably while adding value with renewable raw materials.

PLAFCO – a sustainable plastic substitute made from paper

Plastic is indispensable: it is cheap and practical and found in many disposable products such as drinking straws, disposable tableware or even packaging like bonded beverage cartons or bags – and it has a disastrous effect on the environment. The start-up company Plafco Fibertech Oy has developed a sustainable plastic substitute made of paper that could replace many disposable plastic products in the future.

Agrivoltaics enables the dual use of arable land: Photovoltaic modules, which are mounted on a structure, generate renewable electricity and underneath agricultural crops grow. The approach increases land efficiency and could mitigate conflicts over the use of arable land in the future. A new guideline provides up-to-date information on the technology, its potential and the current state of development.

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.

University of Hohenheim project contributes to maintaining valuable biotopes: Autonomous robot to help prune fruit trees so they stay healthy.

Microbiologists at the University of Tübingen modify bacteria to produce climate-neutral and rapidly degradable bioplastics.

Bioplastics make wood cycles more sustainable

Innovative technologies and bacteria can transform wood residues into sustainable bioplastic packaging. Before bioplastics are broken down into CO2 and water in an environmentally friendly way, they can thus lead lives as products in the cosmetics industry, for example.

Sustainable bioenergy

Biomass from forestry and agriculture along with residues from industry and households can contribute to our energy and raw material shift. Sustainable, regenerative biomass-based energy can become part of the energy mix of the future within the framework of a bioeconomy.

Urban agriculture - 23/04/2020

alphabeet – the green-fingered smartphone

Given the challenges faced by modern agriculture, it is vital to raise people’s awareness of how to change their approach to food. The founders of the Stuttgart-based start-up company farmee GmbH see urban agriculture as the key to making this change possible. The company has developed “alphabeet”, an app designed to encourage consumers to produce their own food. After all, only those combining knowledge and practical experience can be expected…

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.

Clean water thanks to microplastics

He swam the entire length of the River Rhine to draw attention to the contamination of rivers and oceans with plastic waste. After completing his mammoth swim, Prof. Dr. Andreas Fath decided to kill two birds with one stone and do something useful with microplastics. At the Furtwangen University of Applied Sciences campus in Villingen-Schwenningen, Fath is working on a filter system made of plastic waste that can be used to remove pollutants from…

Environmentally friendly alternative to fossil natural gas: methane from biomass

In cooperation with the research unit of the German Technical and Scientific Association for Gas and Water (DVGW), KIT researchers have built a pilot plant in which biogas produced by fermenting residual organic materials can be upgraded to synthetic methane (synthetic SNG). Biobased methane is not only a sustainable energy source for the heating and transport sectors, but also opens up new opportunities for temporary storage of renewable…

The alternative: “bioplastics”

Plastic waste takes years to decompose and pollutes the environment. Nevertheless, plastics are an indispensable part of everyday life. It is therefore all the more important to find a meaningful alternative that is sustainable, environmentally friendly and has better properties and more functionality than conventional plastics. In addition, such an alternative should not be dependent in any way on fossil resources.

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.
