3D-Thermocell project - 17/05/2023

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.

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.

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.

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.

A tasty dish for chickens: Researchers from the University of Hohenheim in Stuttgart were able to feed the animals the first 50 kilos of protein extract that were obtained from pasture. Yet the plants found in fields and meadows offer much more than a new source of protein for pigs and poultry: They could also constitute an alternative to soy for human nutrition. They also form a basis for organic-based plastics and paper, energy, and…

Festo’s high-tech bioreactor - 10/11/2022

Valuable materials of all kinds - produced automatically in living cells

In future, algae could be used to produce practically everything that still requires petroleum, including plastics, fuels, medicines and food. Algae are also climate savers par excellence, because they bind ten times more CO2 than terrestrial plants. Festo, a company based in Esslingen, Germany, has developed a high-tech bioreactor that can be used to automatically cultivate the small green biofactories - and that do so a hundred times more…

Whether in drinking water, food or even in the air: plastic is a global problem - and the full extent of this pollution may go beyond of what we know yet. Researchers at the Karlsruhe Institute of Technology (KIT), together with partners from the Netherlands and Australia, have reviewed conventional assumptions for the transport of plastic in rivers.

Across the EU, more than 300 billion items of packaging are not recycled every year because they consist of a mixture of different materials. Monomaterial packaging on the other hand is easy to recycle. However, it needs to be coated with ultra-thin barrier layers to protect delicate products just as well as compound materials do.

Project BW2Pro - 29/08/2022

Biowaste to Products: biorefinery transforms biowaste into new products

In 2020, Germany’s population collected over 5 million tonnes of biowaste. Most of this was composted, and some was fermented into biogas. Scientists in Baden-Württemberg think there's room for more. Within the project ‘Biowaste to Products’ (BW2Pro) they want to transform biowaste into new products in a biorefinery. The idea is to produce biodegradable plant pots, mulch material, fertilisers, enzymes and biobased plastics in addition to…

Mini-factories for producing bioplastics - 05/05/2022

Bacteria produce bioplastics: resource-saving and very environmentally friendly

Using living cells as mini-factories to produce plastic from nothing more than water, sunlight and carbon dioxide; plastic that is also 100 percent degradable – it sounds far-fetched but it actually works: researchers at the University of Tübingen have genetically engineered cyanobacteria so that they fill their cells to the brim with polyhydroxybutyrate. The researchers are now turning the idea into reality with the development of pilot plants.

The "carbonauten minus CO2 factory 1" will start production of 4,000 t of CO2-reducing plastic granules annually at favorable prices in summer 2022.

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.

Natural fibers in use - 15/02/2022

Sustainable reinforcement of e-bike battery cases

Ansmann AG from Assamstadt provides mobile energy solutions with a focus on sustainability. The BioBattery project, which was awarded the Baden-Württemberg Bioeconomy Innovation Prize, saw Ansmann AG working with the Fraunhofer LBF in Darmstadt to develop a natural fibre reinforced plastic composite for use in e-bike battery cases.

The annual highlight of the industry is the International Conference on Cellulose Fibres in Cologne (www.cellulose-fibres.eu), where the latest innovations were showcased last week: new cellulose fibre technologies for various feedstocks and a wide range of hygiene and textile products as well as alternatives to plastics and carbon fibre for lightweight constructions.

fischertechnik has set a new milestone with the Animal Friends construction kit, as the building blocks and packaging are largely made of renewable resources and the models depict playful animals in new colours. The company is thereby taking another major step towards sustainability. The bio-based building set recently won the Toy Award, one of the most prestigious awards in the industry.

The HUEHOCO GROUP Holding GmbH & Co. KG, a family-owned company from Wuppertal, North Rhine-Westphalia, has acquired a 5 percent stake in carbonauten GmbH. The start-up is in negotiations with further interested parties from Germany and Japan. With the international metal strip refiner HUEHOCO Group, which has sites on 4 continents, the "minus CO2 factory" has acquired its first industrial partner.

Protection against game damage - 13/01/2022

Sapling protectors made of domestic wood - simple but effective

Young forest plants need protecting against damage and as a result it’s often hard to miss the colourful plastic tree guard sleeves when out walking in forests. These tree guard sleeves are neither pleasing to the eye nor sustainable. Bernd Schairer UG from Albstadt has developed sapling protectors made of wood that contain no plastics, metals or chemicals, do not require removal and disposal, and are produced in a socially responsible way.

Renewable raw materials and the circular economy in the textile industry - 08/12/2021

Outdoor equipment made from cellulose, castor oil and coffee grounds - functional and durable

VAUDE develops outdoor gear made from natural or recycled materials that are harmless to people and the environment while protecting against the wind and rain. The company relies on renewable raw materials, biobased plastics and the circular economy.

In reforestation projects, the seedlings must be protected. So-called growth covers prevent game from feeding on the young plants and help to ensure that they are not prevented from growing by other plants. Previously used sheaths made of plastic and metal are often not removed in time and pollute the environment. The DITF have developed a biodegradable yarn for growth covers from renewable raw materials.
