"Better Peptides Platform: New Approaches for the Production of Peptides"

The Badische Peptide und Proteine GmbH has developed a new biotechnological process to produce peptides in a more sustainable, larger scale, and more cost efficient way. This company's approach puts nature first and made it possible to generate better and cheaper peptide products in quantities of grams and beyond.

Production requires only the utilization of everyday, renewable starting material; in plain English that means curd soap and starch. In this way, peptides can be produced so cheaply that it they would become accessible for agriculture.

A fan blade in the shape of an owl’s wing

The almost completely silent flight of an owl inspired the developer in the design of their fan blades. They have transferred the properties of owls’ wings into a technical application (bionic), resulting in the characteristic trailing edges of their fan blades.
 
The distinct-looking shape of this edge reduces the fan’s typical noise during operation and became a trademark of Ziehl-Abegg SE. These fan blades have potential applications in heating or cooling systems, heat pumps, or in electronic cooling applications.
 
This example displays the significant potential of bionics for innovative product solutions, which is a core element of the bioeconomy.

"Clean water with renewable raw materials"


A joint project has developed a multi-step process that generates activated charcoal out of fibrous biomass from landscaping activities.

This biomass is first hacked into small pieces and treated with warm water and is then mechanically dried. The extracted liquid can then be used to produce biogas. The dehydrated press cake then becomes biochar as it is pyrolyzed in the absence of oxygen. This biochar then undergoes partial oxidation, becoming activated charcoal. A significant portion of the energy required for the process is made out of the gas created during the pyrolysis process. Once the activated charcoal is used, it can be removed with sewage sludge and thermally revaluated.

The production of this biobased activated charcoal not only replaces fossil and imported raw materials, it also contributes indirectly to the preservation of biodiversity in that it provides utilization options for residue biomass created through landscaping and mowing. This allows regionally created biomass to be implemented in a way that creates value and value chains.

Learning from nature

A native of the Namib, the head-stander beetle has developed a unique survival strategy. It collects dewdrops and is able to direct them towards its mouth due to the special surface texture of its carapace. This characteristic inspired Sto SE & Co. KGaA, who developed the idea into a type of exterior paint that can drain water away in a specific way.
 
Painted facades not only dry in record time, but the paint keeps both the façade and the wall itself dry long-term. Fungus and algae have no chance to take hold. This comes with the benefit of avoiding biocide applications, another advantage over conventional exterior paints.
 
The main goal of the bioeconomy is applying biological knowledge to give innovative products a leg up over their traditional counterparts, just like is the case for this bionic exterior paint.

SafranMatters: We’re bringing robotics to the farm!

The vision of the start-up company Innovation Matters is to optimize laborious agricultural processes with the help of robotics, and to make these processes more efficient, sustainable and economical. Saffron is one of the most valuable spices in the world.
 
Innovation Matters GbR aims to take a holistic approach with “SafranMatters”. Their concept involves planting, maintaining, and harvesting. A prototype of the harvesting machine “Oscar” automatically recognizes saffron blossoms. The cutting head is maneuvered into position and removes the blossom, which falls into the harvest container. The electrically powered machine is very agile and consumes little energy. Oscar would allow any farmer to cultivate saffron in small- or large-scale production. In this way, consumers would have access to a fair and delicious spice. The next steps for the project include optimizing the design and implementing new functionalities, including applications for other plant species.

A bioeconomical material for humans and nature: Using rattan to preserve the rainforest


karuun GmbH has a new interpretation of rattan. An energy efficient technology serves to turn the natural structure of the rattan palm into a globally unique Nature Tech Material, that's both sustainable and economical.

Minimal energy use is required to inject light- and UV-stable pigments into the capillaries of the rattan cane. After that, the canes are milled square, glued together, and pressed into blocks. These blocks display different physical properties depending on how they are cut regarding the grain direction of the fibers within, giving them a wide array of implementation options: as both robust and formable or light- and air-permeable products.

Rattan, as a quickly renewable resource, grows freely from tree to tree like a vine and is sustainably harvested by hand by local farmers.The sustainability of this process is certified via a life-cycle assessment (LCA) and is traceable using an app. The company is also active locally in Indonesia. Through the purchase and usage of rattan by karuun® increases the value of tropical jungles, provides a stable, long-term income for farmers, and creates an incentive for the preservation of forest resources.

Cascade utilization in food production via microgreens and gourmet mushrooms

Food production and feeding the growing global population face a variety of challenges. Limited resources must be used efficiently, which means creating value from residual materials wherever possible. Long transport routes often account for high energy consumption and significant environmental impacts. This is particularly true for fresh, delicate goods which rot quickly and are at risk of adding to the volume of food waste. Intelligent, regional concepts are an advantage here.
 
The entrepreneurial idea of Kleinblatt GmbH is a weather-independent, all year round production of high quality fresh microgreens and gourmet mushrooms for local gastronomies. To reach that goal, Kleinblatt produces using a controlled environmental Agriculture (CEA) concept in the city of Stuttgart. Cultivation of the microgreens begins with a hemp-based growing medium. The residues of used growing medium can then be used as a substrate for the cultivation of the gourmet mushrooms. Mushrooms and microgreens are then sold directly to local gastronomies, to establish regional value creation and short supply chains. Just like that, Kleinblatt contributes to a regional, circular economy and a living bioeconomy.

CO2-neutral fibers and biobased polymers from annual plants
 
Annual plants can be used like wood to produce fibers or chemicals. This process requires investment in large scale plants, high amounts of energy and creates residual material streams contaminated with chemicals. Technical, operational, and economic challenges have limited the production of annual plant-based fibers, until now.


The steam explosion process offers a chemical-free alternative. Heating under steam and high pressure is followed by a sudden decompression, making lignocellulosic material available for later process steps. Fibers365 GmbH processes regionally cultivated annual plants with their “steam explosion” technology to produce fibers from straw and cellulose containing annual plants. The concept consists of a combination of modular “steam fiber units” with biogas plants. Residual materials after fiber extraction are used as substrate for energy production in the biogas plant and therefore provide the energy for the fiber production. A resulting liquid phase can be used as a substrate for biorefineries, fermentative processes, and biofactories. The innovation involves the technical concept and construction, which allows for decentralized steam explosion plants in agricultural areas and in the vicinity of biogas plants. Regional biomass that may otherwise be overlooked can be made into transportable biobased raw materials for industrial purposes.

‘RECOU’ – An ecological packaging material made of grain husks
 
Packaging materials like EPS (Styrofoam) are made from limited fossil resources, and improper disposal can lead to the release of environmentally harmful microplastics. Beyond that, their production requires large amounts of energy and creates CO2. Existing paper-based packing alternatives provide a limited level of cushioning. Therefore, environmentally friendly packing materials whose production is not resource-intensive are needed.
 
PROSERVATION uses grain husks, the outer coating of a cereal grain, to produce formed packing material. Large quantities of these husks are produced as a result of spelt processing. Combined via a biological binding agent, these leftover husks transform into ‘RECOU’ packing material through only a few production steps. This process requires small amounts of energy and the final product is entirely made from natural products. RECOU can be formed into any shape and its physical properties are comparable to petrochemical packing material (such as Styrofoam). Consequently, it offers an ecologically sound alternative for many packing applications. By using agricultural residues as packing material, energy, resource demand, and CO2 emissions can be reduced during the shipping of fragile goods.

Sustainable, regional production of high quality seed oils from side streams
 
Juicing apples, making banana chips, and mashing sauerkraut - from early on, Paul Belthle showed a great interest in the making and processing of foods. At just 12 years old, he received an oil press as a gift. This press would set the stage for the founding of ‘Die Ölfreunde’ (EN: ‘The Oil Friends’), which was established 2019 in the Upper Danube Valley. Regional and sustainable concepts were important to Paul right from the start.
 
Die Ölfreunde produce and sell high quality seed oils from rapeseed, camelina, hemp, and black cumin. The oil seeds are obtained from farmers in the local area, to keep the carbon footprint small. The mechanical cold pressing creates a side stream of nutrient-rich press cakes. These cakes are processed into high quality flours and protein-rich food and feed for humans and animals alike. The family business is already present in retail and is planning to expand. Die Ölfreunde offer consultation to customers at their in-house farm store. Paul guides tours through the operation, where he explains the idea, intention, production, and distribution. Their concept strives wherever possible to strengthen sustainable and regional value creation and supply chains. Die Ölfreunde strive to be an example to young entrepreneurs and a circular bioeconomy.

From plant to paper – Bioeconomy through the entire lifecycle

Biogas plant operators and the manufacturer of fiber and paper products have established a new kind of value chain that follows the product from the field all the way to the shelf. By utilizing steam and pressure, valuable fibers extracted from cup plant can produce recyclable packaging. Biogas, produced from the remaining plant residues, can eventually be transformed on site into electricity or into heat for heat networks and directly marketed.
 
This novel type of business model generates a new income stream for farmers, since the utilization of fiber offers the potential to produce new products right on the farm. It is also becoming apparent that, compared to other energy plants, cup plant is more insect-friendly and more able to improve local humus structure. Another benefit of cup plant is its low maintenance requirements as a perennial plant, since it produces biomass for several harvest cycles after it is established.
 
This serves as a nice example of the bioeconomy, new value networks, and the advantages of coupled and cascade usages as well as the connection of ecology and economy with technological and social issues.

Increasing efficiency for agriculture in Hohenlohe by recycling nutrients from manure

In Kupferzell, an innovative plant concept was developed that could sustainably utilize slurry and manure. This farmer has expanded his biogas plant, the first step in producing green energy, so that it can also recover phosphorus, nitrogen, potassium fertilizer, and other organic soil improvers from biogas digestate.
 
These concentrated manure products are more transportable, marketable, and producible according to demand. Sponsored by the European Union as well as the Ministry of Food, Rural Affairs and Consumer Protection, under the framework of the agricultural European Innovation Partnership “Agricultural Productivity and Sustainability” (“Landwirtschaftliche Produktivität und Nachhaltigkeit” (EIP-AGRI)), this project was funded with 1.3 million Euro. This proves that bioeconomical approaches can contribute to increases in efficiency and resource protection for agricultural areas.

Optimization of nitrogen during lentil cultivation via seeding with rhizobacteria

Growing consumer interest in locally cultivated foodstuffs with high protein content is encouraging the new uses of traditional plant crops. EIP-Agri Project Rhizolinse (Rhizolentil) is investigating the potential of natural symbiosis between lentils and rhizobiaceae.
 
These bacteria convert nitrogen in the air and produce essential nutrients for the plants. By providing suitable soil bacteria, the lentil plants can grow in conditions that promote the formation of root nodules, which have a positive effect on the growth, yield, and quality of the lentil product.
 
This efficient application of biological knowledge can contribute to the revival of traditionally, nutritionally, and ecologically valuable crop varieties in Baden-Württemberg. This project also serves as a good example of the union of ecology and economy in the knowledge-based bioeconomy.
