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.

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.

Climate change is causing temperatures to rise and storms to increase. In inner cities, summers are becoming a burden for people. Densification increases the amount of sealed surfaces. Green facades bring more green into cities. If textile storage structures are used, they can even actively contribute to flood protection. The German Institutes of Textile and Fiber Research (DITF) have developed a "Living Wall".

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.

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.

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.

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.

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.

Food of the future: new production methods - 06/09/2023

NewFoodSystems: innovation space for tomorrow’s food

A rapidly growing world population and simultaneously rapidly shrinking arable land – these are just some of the major challenges facing the food industry. But how can solutions be found? Answers are being sought by the bioeconomy innovation space NewFoodSystems. Funded by the German Federal Ministry of Education and Research (BMBF), it is a network where science and industry can come together to develop sustainable food systems of the future.

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.

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.

Molecular biologist Professor Holger Puchta from KIT is granted funding within a Reinhart Koselleck Project by the German Research Foundation (DFG) for work on specific restructuring of plant genomes. Puchta, a pioneer of green genetic engineering, has used molecular scissors in plants for 30 years now. His new project is aimed at using the CRISPR/Cas method to freely combine genes in crops, thus making Gregor Mendel’s dream come true.

Industrial biocatalysis with enzymes is deemed to be a “game changer” in the development of a sustainable chemical industry. Enzymes can be used to synthesize an impressive range of complex molecules. Researchers of KIT have now developed a new class of materials by producing enzyme foams of tremendous stability and activity. The researchers have already filed a patent application on the process to produce enzyme foams.

Rising sea levels due to climate change and artificial irrigation cause soil salinity to increase. This has a negative impact on agriculture, including viticulture. The plants die, yields decrease. Researchers of Karlsruhe Institute of Technology (KIT) have therefore studied a wild grapevine of higher salt tolerance. Their goal is to identify the genetic factors that make the grapevine resilient.

The AlbLavendel project - 20/11/2023

Swabian lavender cultivation: aesthetic and sustainable

Blue-violet, fragrant fields like those in Provence may soon become a common sight in the Swabian Alb. As part of the AlbLavendel project, the University of Hohenheim along with the company naturamus GmbH and the German Institutes of Textile and Fibre Research Denkendorf has started to investigate the cultivation of lavender, the production of essential oils and the use of distillation residues for producing textile fibres in the local region.

Wasser 3.0: #detect|remove|reuse - 31/10/2023

How to sustainably remove and recycle microplastics from water

We all pollute our water with things we use in our everyday lives. In the process, microplastics and micropollutants accumulate in sometimes significant quantities and are difficult to remove. This has increasingly devastating consequences for our health and the environment. Wasser 3.0, a non-profit start-up from Karlsruhe, has declared war on this problem by developing a customisable process to detect, remove and even recycle these pollutants.

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.

Mobile units for processing fruit and vegetables on-site may play an important role in food supply in 2035. The EU’s FOX project investigated the form that such local food chains might take. To this end, Fraunhofer ISI developed future scenarios that could be used to test the viability of business models for regional food processing and distribution.

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.

Autonomous and robust navigation is an essential capability for agricultural robots or machines that are to reach a new level of autonomy to manoeuver safely and reliably in their environment. Fraunhofer IPA will showcase what is currently technologically and economically feasible with live demos at agritechnica, the agricultural trade fair taking place in Hanover from November 12 to 18, 2023.

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.

The European Parliament’s amendments to the proposal for a Regulation on Artificial Intelligence (AI) may be defined as a socio-ecological turnaround compared to the European Commission’s existing draft. The parliamentary draft proposes a series of environmental and climate-related provisions which, in the Oeko-Institut’s view, are feasible and technically achievable. The Oeko-Institut has reviewed these proposals in a Policy Paper.

The Cultivated B (TCB) began discussions with the European Food Safety Authority (EFSA) and officially entered the pre-submission process for novel food approval of a novel or non-farmed sausage product. Subsequent to the official submission, TCB will emerge as world’s first biotech company to apply for EFSA certification for cultivated meat. This is a pivotal first step in the evolution of the cultivated meat market.

Textiles are a given in civil engineering. Until now, textiles made of resistant synthetic fibers have been used for this purpose, having a long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade when it has done its job. Natural fibers, in contrast, often decompose too quickly. The DITF are developing a bio-based protective coating that extends their service life.

What is new is that the IGB takes a systemic approach, focusing on biobased and circular value…

Alternative construction materials: mycelium-based materials - 20/12/2023

Using fungi to create sustainable and economical mycelium-based materials

Most of us see fungi as just food - and possibly pathogens. This is a mistake, because these amazing organisms are capable of much more: they grow on plant residues of all kinds, forming a dense and interconnected structure as they spread. The resulting material can be moulded into desired shapes and be turned into new sustainable and economically attractive products such as leather and polystyrene substitutes or building materials.
