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
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
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
The world will have to take another look at renewable energy. We need to start thinking visionary and large-scale. Time is over when solar and wind energies had to adapt themselves to their environment. On the contrary, from now on sustainable energy is actively going to create its environment. Thoughts about energy producing landscapes emerge.
Renewable energy sources are by nature ready to harvest anywhere in the world, and therefore not a source of international conflict by themselves. However, they depend in part on critical materials – materials of which the supply is by no means assured, particularly if renewable energy should grow very fast. The most important group of
Geopolitics has long circled around reserves of fossil fuels, the most critical assets in a fossil-based world. But although they will be around for a few more decades, fossil fuels will gradually become less important as a global power factor. What will come in their place? Will energy continue its role in a different form?
Some energy analysts propose that system changes will seriously slow down the advent of sustainable and intermittent energy sources. Grid instability and/or its prevention would add appreciably to sustainable energy costs. But some system changes will propel, rather than slow down the development of renewable energy. New entrants like electric car producers will soon develop
3D printing has the future. It will change the way in which we produce objects – maybe much less in factories and much more in shops around the corner. But so far, biobased materials have been difficult to 3D print. Most 3D printers use heat to melt the plastic or metal to be printed, and
Beautiful short video by @Avantium on #biobased plastics made from plants, wood, and CO2 and why they are so important for the future and health of our planet - the only way is up! youtu.be/pN_SSvDYB80
