Artificial spider silk, imitating ‘the toughest material on earth’
Spider silk combines properties that are very difficult to achieve for man-made materials. It is claimed to be 340 times stronger than steel; we are also told that a net woven from spider silk threads 1 cm thick would be able to stop a Boeing 747 in full flight. And yet, spider silk is just
Geopolitics of information, the next conflict zone
In four earlier articles we came to the conclusion that geopolitics of fossil, mineral and agricultural resources will become less important. But a new geopolitical dimension quickly rises to the forefront: geopolitics of information. Information becomes less reliable. People create their own worlds with social media, which leaves less and less space for generally shared
Artificial silk: the next biotechnological frontier, about to be crossed
For a long time, silk has figured as a proverbial example of nature’s skills: strong and breathable, and soft to the skin as no man-made material could achieve. But we are about to cross this border: artificial silk has been synthesized, or at least materials very close to it; it may come to the market
Young farmers and the lack of large-scale agricultural innovation projects
Last week I visited a network meeting focusing on rural development. This focus area lies at a somewhat greater distance from direct bio-based developments, but nevertheless will be impacted by the bio-based economy. One of the participants mentioned the lack of larger scale agricultural innovation projects. The reason I attended this meeting was that I
The role of chemistry in the reduction of plastic waste
In a first article, we proposed that plastic waste should no longer exist in ten to fifteen years from now. This ambitious goal needs to be tackled from two sides: plastics design on the input side, and dedicated processing on the output side. In both processes, chemists play a major role. And industry should show
Plastic waste: let’s put an end to it in 10 to 15 years
Mankind needs to set a clear goal: plastic waste should no longer exist in ten to fifteen years from now. This ambitious goal needs to be tackled from two sides: plastics design on the input side, and dedicated processing on the output side. Circular design concepts and professional reprocessing, including clever collection schemes, should help
Geopolitics of phosphate in a biobased economy
The impact of mineral, fossil and agricultural assets as a weapon in international politics will gradually become smaller, we concluded in three articles. Substitution of critical materials and the development of new technologies play a crucial role in this process. But the geopolitics of phosphate might be an exception. For there is no alternative to
Doughnut economics, or why economists should learn more about technology
One of today’s economic bestsellers is Doughnut Economics, written by the British economist Kate Raworth. Her book is an outright attack on the dominant neoliberal economic theory. Permanent growth is impossible! In growing permanently, we will transgress social and ecological boundaries! I saw her on TV and right away asked myself how her project could
