Outlook on the future of agriculture - 30/11/2020

Agriculture 4.0 – ultramodern and without harmful plant protection products

The demand for organic products is continuing to grow; at the same time nature is being preserved – so why not switch completely to organic farming? The answer is simple: because not everyone can afford it, and with current consumption patterns not everyone would get enough to eat. A cooperative project is researching an an agricultural system that falls between conventional and organic farming.

Approximately 3,000 participants from all over the world are taking part today in the Global Bioeconomy Summit 2020. That Summit takes place from November 16 to 20, guided virtually from Berlin. Germany's partners are ASEAN/Thailand, Japan, Latin America, East Africa and - of particular importance - the EU Commission.

Development of biogenic packaging - 16/11/2020

Sustainable packaging - the devil is in the detail

Modern packaging often boils down to a tick list of biogenic origin and/or biodegradability. But comprehensive sustainable packaging concepts need more than just that. Perishable foods, for example, require special barrier properties. The Albstadt-Sigmaringen University of Applied Sciences is researching packaging concepts for their sustainability.

Packaging of the future

What will the packaging of the future look like, and what will be required of it? Can packaging be biobased, recyclable, sustainable and economic? In Baden-Württemberg, there are various approaches to developing packaging with the above properties from various sources including agricultural residual and side streams as well as municipal waste.

A new future study by the Fraunhofer Institute for Systems and Innovation Research ISI uses four different scenarios to provide insights into how natural resources could be used in agriculture in 2035 and what role digital decision support systems can play for farmers in this context.

EU research project with the participation of the University of Hohenheim searches for new, sustainable food additives and packaging materials from seaweeds and seagrasses.

Products made from bio-based plastics must undergo the same testing procedures as conventional plastic products to access the market of the European Union (EU). Thereby a health risk for consumers is excluded. Plastics intended to be certified as biodegradable or compostable must undergo additional tests.

In a review article recently published in the scientific journal Waste Management, ATB scientists outline the possibility of using insects to efficiently and sustainably recycle food waste. This insect-based bioconversion can help to close material cycles in the food value chain.

Phosphorus recovery from sewage sludge - 21/10/2020

Bacteria help to recycle phosphorus

Biotechnology for the bioeconomy: in something known as the P-bac process, sulphur bacteria extract phosphorus from sewage sludge ash. Phosphorus is one of the key building blocks of life and an essential nutrient for plant growth. When there is not enough phosphorus in the soil, farmers apply it via organic or mineral fertilisers.

The urgency of the ongoing climate change is increasing. There is no doubt that emissions must be drastically reduced at all levels, but that is not enough. To prevent the worst consequences of climate change, additional carbon sinks, so-called negative emissions, are needed. A recently published whitepaper clearly and scientifically substantiates that biochar is a key technology in this fight against climate change.

An interdisciplinary team of scientists at the Max Planck Institutes for Intelligent Systems and Solid State Research has developed a biocompatible microswimmer made of carbon nitride, which they can propel forward through light. The particle can also store solar energy similar to miniature solar cells equipped with batteries, and can thus also swim in the dark using the stored energy.

Germany generates around 38 kilograms of plastic waste per capita each year. Researchers from the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and the Fraunhofer Institute for Process Engineering and Packaging IVV are now working to establish a holistic concept for the sustainable use of biologically degradable packaging materials in the cosmetics industry. The project is focusing on polyhydroxyalkanoates (PHAs).

The European Environment Agency (EEA) recently published its new report “Biodegradable and compostable plastics – challenges and opportunities”. The report highlights many positive aspects of biodegradable and compostable plastics. Unfortunately, its interpretation in several media outlets focused exclusively on the few critical assumptions the report makes regarding consumer perception.

The European Commission (EC) and the European Investment Bank (EIB) have launched a circular bioeconomy fund with a target size of €250m.

The workshop organised by Science Business, a leading publication on European research and innovation, involving BIC and the BBI JU, refined several key policy recommendations to European and national policymakers.

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.
