Microorganisms degrade biobased turf infill - 17/10/2023

Eco-friendly artificial turf: a sports pitch that’s good for people and the environment

There are thousands of artificial turf pitches in Germany. They are extremely practical, but often not at all environmentally friendly. When it rains or the pitch is used, plastic particles from the rubber granules can be released into the envronment, where they remain. Researchers at the University of Stuttgart along with the company TECNARO are now developing an artificial turf with an infill that biodegrades as soon as it leaves the pitch.

Doubling food production, saving water, and increasing carbon storage capacity – this may sound paradoxical, but would be theoretically feasible. Reaching this goal, however, would require a radical spatial reorganization of land use. This is the conclusion of researchers from Karlsruhe Institute of Technology (KIT) and the Heidelberg Institute for Geoinformation Technology (HeiGIT) of Heidelberg University.

Researchers at the University of Hohenheim are working on an alternative to fish consisting of microalgae. Advantage: Microalgae have high quality ingredients and also contribute to carbon storage.

Preventing waste from instant meals - 05/10/2023

EDGGY: edible packaging film made from eggshell waste

Many instant meals such as ramen soups have both a protective outer packaging and individual ingredients in small plastic sachets. To prevent this environmentally harmful waste, five students at the University of Hohenheim have developed a sustainable film based on eggshells and plant proteins that dissolves in hot water and is edible.

Researchers at the University of Freiburg quantify the amount of material needed to enable people to live without poverty. 1.2 billion people live in poverty. To lift them out of it, an average of about six tons of raw materials are needed per person and year – in particular minerals, fossil fuels, biomass and metal ores. This is the result of a study by researchers from the Chair of Sustainable Energy and Material Flow Management.

Germany has the most active market, Southern Europe wants more variety, and people in Poland find dairy substitutes too expensive, according to a recent study by the University of Hohenheim.

Konstanz chemists develop mineral plastics with numerous positive properties from sustainable basic building blocks and, together with biologists, demonstrate the material's excellent microbiological degradability.

What impacts do agrochemicals have on the ongoing global insect decline? Biologists at the University of Konstanz have found out that aversive learning is impaired in bumblebees exposed to glyphosate. Their study is published in the journal Science of the Total Environment.

Can biosurfactants increase microbiological oil degradation in North Sea seawater? An international research team from the universities of Stuttgart und Tübingen, together with the China West Normal University and the University of Georgia, have been exploring this question and the results have revealed the potential for a more effective and environmentally friendly oil spill response.

As the world's population continues to grow, the construction industry faces the challenge of using fewer resources and switching to sustainable materials. Scientists from the Universities of Stuttgart and Freiburg are developing new interdisciplinary approaches to construction for the future.

Insightful study with participation from the University of Konstanz warns of human-induced impacts on the marine ecosystem.

7591 red deer, 3443 roe deer, 4876 wild boar, 36 wolves, 16 lynxes and 227 red foxes: These are the results of the first standardised monitoring of wildlife populations in ten large protected areas in Germany. It was carried out by scientists at the University of Freiburg led by Prof. Dr. Marco Heurich and Dr. Christian Fiderer from the Faculty of Environment and Natural Resources.

Reinventing ‘wood’ with programmable bacteria

Conserving wood by producing furniture and other objects from wood-based materials with the help of microorganisms? That is exactly what a team of researchers from the University of Freiburg and the Leibniz Institute for New Materials (INM) in Saarbrücken is working on in the DELIVER project. The aim is to create a database of materials with a broad range of controllable properties for various applications that can be produced from wood waste.

Team of Freiburg researchers shows how information about the quantity of absorbed light passes from the leaves to the roots. Plant growth is driven by light and supplied with energy through photosynthesis by green leaves. It is the same for roots that grow in the dark – they receive the products of photosynthesis, in particular sucrose, i.e. sugar, via the central transportation pathways of phloem.

Daisies, peas, canola, etc.: Researchers at the University of Hohenheim want to replace gluten protein with new alternatives. Instead of ovens, 3-D printers would be possible

Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. An international team of plant biologists has demonstrated that it is based on the activity of a certain factor, the target of rapamycin (TOR) protein.

Diatoms as a biorefinery - 05/05/2023

Microalgae: sustainable chemical production in a mini factory

Renewable raw materials that can be used as alternatives to fossil resources already exist. However, to turn them into everyday products, plant oils and other renewable raw materials not only have to be extracted, but often have to undergo complex chemical processing. Researchers at the University of Konstanz have now converted microalgae cells into tiny refineries to produce and upgrade raw materials, creating a supply of sustainable chemicals.

Sustainability is a major challenge in the food and packaging industry. Plastic packaging is being replaced by organic-based and biodegradable materials, but it must still fulfill high functional requirements. A team of researchers at the University of Hohenheim has developed a new coating system that is both water-impermeable, heat-resistant, and mechanically durable as well as being suitable for consumption, and biodegradable at the same time.

Milana will strengthen the research of the Cluster of Excellence Living, Adaptive and Energy-autonomous Materials (livMatS) in the field and work closely with scientists from the Freiburg Center for Interactive Materials and Bioinspired Technologies (FIT) and the Freiburg Materials Research Center (FMF).

Ready-made meals are ideal for quickly satisfying hunger. However, the quick snacks produce a lot of environmentally harmful plastic waste. To tackle this problem, the student team EDGGY from the University of Hohenheim in Stuttgart rolled up its sleeves and developed edible packaging made from eggshells and other plant-based raw materials. And even better: they simply dissolve in the hot water and can be eaten as an additional protein boost.
