Bioeconomy

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.

Paper instead of plastic: sustainable packaging with a good conscience

Replacing plastic – for example in packaging – is not that easy but nevertheless urgently needed. In the 3D-Thermocell project, researchers at DHBW Karlsruhe are currently developing new plastic substitute products made of thermoformable paper as a renewable resource, which should be cheap and light and easy to dispose of along with waste paper. The characterisation and application of demonstration models will start soon.

This year's Venice Architecture Biennale sees itself as a "Laboratory of the Future". Bio-composites are not just dreams of the future in architecture. The German Institutes of Textile and Fiber Research (DITF) have developed a sustainable material for support profiles and connecting nodes, which will be on display at Palazzo Mora during the Biennale from May 20 to November 26.

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.

At the Fraunhofer Center for Chemical-Biotechnological Processes CBP in Leuna, Germany, representatives from politics, research and industry opened a novel pilot plant for the mild processing of rapeseed to increase the added-value potential of rape as a raw material.

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.

Roboticists at the Max Planck Institute for Intelligent Systems in Stuttgart have developed a jellyfish-inspired underwater robot with which they hope one day to collect waste from the bottom of the ocean. The almost noise-free prototype can trap objects underneath its body without physical contact, thereby enabling safe interactions in delicate environments such as coral reefs. Jellyfish-Bot could become a tool for environmental remediation.

In collaboration with the project partners CG TEC, Cordenka, ElringKlinger, Fiber Engineering and Technikum Laubholz, the DITF are developing a new fiber composite material (CELLUN) with reinforcing fibers made of cellulose. The matrix of the material is a thermoplastic cellulose derivative. CELLUN made from renewable biopolymers enables the replacement of glass or carbon fibers in the production of industrial molded parts.

FamoS: climate protection on facades

Resource-efficient water management, photovoltaic modules and innovative facade greening - FamoS is all that. By combining proven elements, the ‘facade module with synergy’ makes a valuable contribution to combatting climate change and boosting climate resilience in cities.

Composite materials provide stability in aircraft parts, sports equipment, and everyday household items. However, most of these materials have a poor carbon footprint and are not naturally degradable. A more sustainable alternative has been developed by a team from the University of Stuttgart. This completely bio-based composite material is made of flax fibers and the biopolymer chitosan.

Digital manufacturing processes enable buildings to be constructed with flax and willow

A switch to sustainable and circular construction concepts is needed to significantly reduce greenhouse gas emissions in the construction sector. At the German National Garden Show (Bundesgartenschau) in Mannheim, FibR GmbH, together with researchers from the Karlsruhe Institute of Technology, will be showcasing two innovative buildings made from flax and willow, renewable raw materials that exemplify possible building concepts of the future.

PeePower™ – energy from urine

The objective of the PeePower™ BUGA 2023 collaborative research project is to produce green hydrogen and platform chemicals from wastewater. This fits in nicely with BUGA 2023’s (German National Garden Show) four major themes, namely, climate, energy, environment and food security.

A novel, both environmentally friendly and cost-saving process for the production of carbon fibers from lignin has been developed at DITF. It is characterized by high energy-saving potential. The avoidance of solvents and the use of natural raw materials make the process environmentally friendly.

In February, the Estonian-based startup New Standard Oil successfully commissioned their first industrial-scale prototype for drying and torrefaction of biogenic feedstock operating with superheated steam at atmospheric pressure.

Researchers at the University of Freiburg have examined how mulching at different times affects insect flower-visitors and larvae.

The Tech4Biowaste database will be showcased online by its developers on 30 March 2023

Start for an EU-wide collaborative project: Under the leadership of the French company Fairbrics SAS, 17 project partners from 7 European countries are coming together. The common goal is to produce end products from polyester in a closed cycle using industrial CO2 emissions and to bring them to market maturity. The DITF produce synthetic fibers from plastics of non-fossil origin.

nova-Institute’s take on the recently published EU proposal for a Packaging and Packaging Waste Regulation as well as the new policy framework for biobased, biodegradable and compostable plastics.

On February 16, 2023, Baden-Württemberg’s Minister of Science, Research and the Arts, Petra Olschowski, visited the University of Freiburg. The focus of her visit was on sustainability and the transfer of knowledge. The minister learned all about how the day-to-day running of the university is becoming sustainable, and the wide-ranging climate protection and environmental safety measures. She also visited the livMatS pavilion.
