Bioeconomy

New EIT Food project aims to use computer models to optimize bakery processes in order to minimize food waste, energy consumption, and CO2 emissions. Prof. Dr. Bernd Hitzmann: "With the help of simulations, we want to optimize the processes in bakeries, which leads to higher economic and ecological efficiency. This not only reduces production costs for bakeries, but also helps to slow the progress of climate change".

New biomaterials developed at the University of Bayreuth eliminate risk of infection and facilitate healing processes. These nanostructured materials are based on spider silk proteins. They prevent colonization by bacteria and fungi, but at the same time proactively assist in the regeneration of human tissue. They are therefore ideal for implants, wound dressings, prostheses, contact lenses, and other everyday aids.

A viscous biopaste that is easy to process, solidifies quickly and is suitable for producing even complex structures using the 3D printing process has been developed by a research team headed by Prof. Dr. Marie-Pierre Laborie from the Chair of Forest Biomaterials at the University of Freiburg. The wood-based biodegradable synthetic could potentially be used in lightweight construction, amongst other things.

What alternatives to conventional agriculture exist to produce carbohydrates for food and feed? Scientists at Heidelberg University performed model calculations for artificial sugar production with a view towards synthesis of other carbohydrates such as starch.

Time for climate protection is pressing. One approach to tackle this challenge is to use the greenhouse gas CO2 as a raw material for chemicals. The researchers of the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB, together with partners from science and industry, were able to produce a value-added terpenoid dye from CO2 adsorbed from air by a combination of electrochemical and biotechnological conversion.

In Sumatra, small-scale farmers in particular play a key role, according to a study on the conversion of rainforests into monocultures and their effects Oil palm plantations as far as the eye can see. In addition to a dramatic loss of many animal and plant species, such plantations often lead to massive environmental problems.

Packaging protects products during transport and storage. In order to develop sustainable packaging and conserve resources, Henkel developed an evaluation tool that quickly and reliably checks plastic packaging for recyclability. The tool has now been expanded to include common materials, so that packaging made of paper/cardboard, glass, aluminum and tinplate can be analyzed in addition to plastic. Fraunhofer UMSICHT tested the software tool.

A soft material that heals itself instantaneously is now reality.

Since the beginning of 2019, the Fraunhofer Institute for Biomedical Engineering IBMT has been working on a comprehensive characterization and humantoxicological assessment of nanocellulose along its life cycle in the BMBF-funded joint project "NanoCELL" under the coordination of Postnova Analytics GmbH, in order to achieve a reliable risk assessment and safe use in environmentally friendly packaging materials.

Qualitative soil fertiliser - 10/07/2020

How natural cycles can be closed with wood ash

Recycled material instead of waste: wood ash is good for soil and plants - if the quality is right. The German Federal Quality Association for Food Ash ensures reliable wood ash standards with its certifications. The RAL-Dünger label for fertilisers provides the necessary certification for natural wood ashes to be used in the circular economy.

A report recently published by the Bio-based Industries Consortium (BIC) and Zero Waste Europe (ZWE) shows that with only 16% of the biowaste potential being used, the biowaste management still remains an untapped potential for the European Union to further transition to a Circular Economy. Both organizations jointly produced a first-of-its-kind report estimating the current and future availability of bio-waste in the EU27.

The Witzenhausen Institute and the University of Bayreuth conducted a very interesting study, analysing the compost of several German industrial composting facilities for possible plastic content deriving from compostable biowaste bags. The field study concluded that compostable bags, certified according to the European standard EN 13432, do not pose any challenges to the quality of the compost.

Coffee capsules: wood instead of aluminium

In Germany alone, around three billion disposable coffee capsules made of aluminium and plastic are sold every year. This creates a gigantic waste problem, as only a small proportion of the capsules can be recycled. Fully compostable wooden coffee capsules might be a solution to this problem. The capsules have been developed by a start-up company called rezemo, which also has other biobased packaging solutions in the pipeline.

Perspectives of methane as energy source - 18/06/2020

New technologies for using biogas as a balancing energy

The microorganisms in biogas plants do a great job biologically converting CO₂ and hydrogen, which are primary fermentation products, into methane. Biomethane has a great future as an energy source. Scientists at the University of Hohenheim are investigating new ways to produce and use biomethane.

Degradable biopolymers - 29/05/2020

Bioplastics make wood cycles more sustainable

Innovative technologies and bacteria can transform wood residues into sustainable bioplastic packaging. Before bioplastics are broken down into CO2 and water in an environmentally friendly way, they can thus lead lives as products in the cosmetics industry, for example.

Drought and weather fluctuations threaten agriculture in Germany often in spring already. An increasing number of farmers is forced to irrigate fields artificially. Water resources, however, are limited. Precise information on the state of plants and soils helps farmers take effective measures against damage caused by drought and to enhance irrigation efficiency.

The “Rhizo-Lentil" EIP-AGRI project - 20/05/2020

NovoCarbo turns plant waste into biochar

NovoCarbo GmbH produces biochar from plant residues such as wood chips, nutshells and manure. Different feedstocks, and the way these materials are processed, create biochars with different properties. This makes biochar suitable for different uses, including as a soil conditioner, in biogas plants or as bedding for stables and cowsheds. The Rhizo-Linse project is currently investigating whether biochar is also suitable as inoculant carrier for…

The combustion of conventional fossil fuels accounts for a large share of global CO2 emissions. A great deal of criticism is levelled against cruise and merchant ships for polluting the environment with sooty waste gas and toxic heavy fuels. Researchers at the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT in Oberhausen have been looking into alternative climate-friendly fuels.

Global population is increasing, crucial resources become scarcer. Producing enterprises today have to take the right steps for a sustainable future. On their behalf, scientists of KIT study how the production process may be improved by autonomous production control, reduction of wear parts, or principles of resource-efficient production. Their know-how is presently being pooled in the new research focus “Sustainable Production.”

Electronic devices are still made of lifeless materials. One day, however, “microbial cyborgs” might be used in fuel cells, biosensors, or bioreactors. Scientists of Karlsruhe Institute of Technology (KIT) have created the necessary prerequisite by developing a programmable, biohybrid system consisting of a nanocomposite and the Shewanella oneidensis bacterium that produces electrons.

For hundreds of millions of years plants have had the ability to harness carbon dioxide from the air using solar energy. The Max Planck research network MaxSynBio is on the trail of building artificial cells as sustainable green bioreactors. The research team led by Tobias Erb from the Institute for Terrestrial Microbiology in Marburg has now succeeded in developing a platform for the automated construction of cell-sized photosynthesis modules.
