Circular bioeconomy: an uneasy marriage of concepts, so far
Two concepts, the bioeconomy and the circular economy, have much in common but seem to belong to different universes. Proponents of the circular economy treat the bioeconomy as a fringe phenomenon, that circles around biodegradation; whereas the bioeconomy does not sufficiently value resource efficiency. Inadequate concepts will result in inadequate policies, like stimuli for biofuels
Sustainability and moralism, keep them apart
Are sustainability and moralism always connected? Proponents of sustainability often suggest (rather than openly say) that it is immoral to pursue non-sustainable development paths – to put the future of mankind at risk, indeed that of the entire planet. With climate change as the proverbial example. But sustainability and moralism are not intrinsically connected –
Bio concrete and other construction materials from local resources
As global housing programs are gearing up, the world will need a staggering amount of construction material over the next few decades. This will put a strain on resources, and produce a lot of CO2; unless we discard the present one-size-fits-all approach to materials use (on the basis of Portland cement) and develop local and
Cloning monkeys: slippery slope or dead end?
Last January, the news that a Chinese team of scientists had cloned macaque monkeys drew a lot of attention. Discussion was quick – too quick – to focus on the question if cloning monkeys could lead to cloning humans. But the real question might be: what is the goal of this research? And are there
New materials as a source of inspiration for the fashion industry
Textiles made from pineapple leaves, self-massaging clothes, dresses made from fungi… During Material Xperience 2018 (13-15 March, Ahoy Rotterdam), fashion professionals can enjoy the marvel and the opportunities of many new materials. Trends in new materials for fashion According to the organizers of Material Xperience, there are some important trends in the fashion industry. The
Omega-3 fatty acids produced from corn by marine algae
Omega-3 fatty acids have attracted a lot of attention from protagonists of healthy diets, and from the food industry as well – view their ads. Fatty fish like salmon and sardines are important natural suppliers of these substances to the human diet. But an increasing share of fish comes from fish farms; and much of
Self-healing concrete in full development
Concrete degradation is one of the most costly problems of our time. Concrete will always crack, although less so if well-designed and well-constructed. Cracks will allow water and air to enter into the structure and eventually reach the steel reinforcement. When this erodes, it swells, causing more cracks. Concrete degradation of our infrastructure now requires
Organic is not a good hallmark of quality – this is why
The many ways in which mankind can produce natural compounds with biotechnology, impresses me. Smells, tastes, maybe texture in the near future, remember the synthetic burger, they are excellently produced by the bioreactor. One would expect that food industry would use this to introduce a new product line of industrially prepared AND healthy and qualitatively
