Nanotechnology allows for larger 3D structures

Using the "DNA-origami-technique" researchers can fold single DNA strands into a three-dimensional double-stranded structure. Biophysicist Hendrik Dietz, Professor of Biomolecular Nanotechnology at TU Munich, is an expert of this field and has now developed a new way to make the tiny DNA origami structures larger by transfering viral construction principles to DNA origami technology. This enables him and his team to design and build much larger structures than before – now on the scale of viruses and cell organelles.

Transforming plants into bio-factories

Plants produce a number of metabolites with diverse functions. Many of these metabolites are not only useful to the plant itself, but also have positive effects in humans and animals. However, the extraction of these compounds in sufficient quantities from the naturally producing resources is often laborious and costly. While some metabolites can be produced in bacteria, so far none can be manufactured in plants themselves.

3D skin models to reduce allergens

The skin is the largest organ of the human body and fulfils a number of vital functions. However, the skin is also under constant “attack” – by the sun, water or allergens in clothing and cosmetics. In order to minimise or even exclude allergens in such products, they are tested on skin models in cell culture. For a better understanding of skin physiology the Mannheim University of Applied Sciences (MUAS) and BRAIN AG are developing a new three-dimensional skin model with the aim to provide new insights for health care and cosmetic applications.

Precious single cell oils born of waste water

Today, the strategic alliance ‘ZeroCarbonFootprint – ZeroCarbFP’ is exploring the ways in which this hidden potential could be recovered. The twelve participating partners in the alliance, which officially began work in 2013, are hunting for microorganisms that can use the carbon-rich wastes as substrates and in the process convert them into valuable building blocks and substances for industry.

Making methanol from biomass

Methanol is one of the chemical industry’s most important source materials. It is colourless, flammable and smells of alcohol, and the starting point for manufacturing paints and varnishes as well as fuel. In 2015, the global demand for methanol was about 65 million tonnes. However, this compound of carbon monoxide, water and oxygen is produced mainly from finite resources such as mineral oil, natural gas or coal.

Bio-lubricants from chip frying oil

No plant and no motor can run without lubricants. The metalworking industry is especially dependent on grease and oil. However, most lubricants consist of mineral oil of fossil origin. Recently, though, bio-lubricants made of sunflowers or rapeseed have been entering the market. They can certainly compete with mineral oil based products. But to date they are no more than niche products. The problem: Bio-lubricants are generally more expensive. Also, using these plants directly to make lubricants denies the foodstuffs industry of valuable raw materials.

Using chitin to strengthen textiles

Insects, worms, and crabs are already a delicacy in many countries, and due to their high protein content they are also more and more appreciated as a healthy alternative food source in Germany. Although they’re still rarely seen on the menu of our restaurants, they’re gaining a lot of momentum with scientists for one simple reason: their shells contain chitin, the second most common polysaccharide on this planet – surpassed only by cellulose.

nova-Institut (2017): Market study on biobased polymers

The turnover with bio-based polymers increased from €11 billion in 2014 to nearly €13 million in 2016.
These and more results are available in nova-Institute’s market study “Bio-based Building Blocks and Polymers – Global Capacities and Trends 2016 – 2021”. The study gives an overview of the biobased world market with latest data on capacities and applications. Additionally it shows real data for 2016 and a forecast for 2021.

Liquid wood conserves resources

In 1998, Tecnaro GmbH was set up in Pfinztal as a spin-off from the Frauenhofer Institute for Chemical Technology (ICT) with the aim of bringing a new kind of medium to market. Since its foundation, it has been developing, producing and selling premium thermoplastic materials made from liquid wood. Together with Helmut Nägele, Jürgen Pfitzer has been managing the company in Ilsfeld-Auenstein, Baden-Württemberg, since 1998.
