Five years ago, we visited the outstanding horticultural company Koppert Cress in Monster near The Hague in the Netherlands. Then already, general manager Rob Baan told us that horticulture should concentrate on fresh produce for a healthy diet; with ingredients … Read more
We know that plants grow faster in CO2-rich environments. Horticulturalists enrich the atmosphere in their greenhouses with CO2 to ensure better productivity. Can we imagine fast growing plants that would capture CO2 from the air, and on a large scale? … Read more
‘Again and again, new products fascinate us: the smartphone, the airplane wing that can be glued, new medicines,’ says Ton Schoot Uiterkamp, ‘but we do not think in terms of chains and generally ignore the indirect effects of these inventions. … Read more
Why cannot we lift all barriers for the use of bioenergy? Because the energy sector is much larger than the food sector. The 20 billion tons of fossil fuels that mankind uses each year, is equivalent to 40 billion tons … Read more
Since the turn of the century, there is a discussion raging on the limits to biomass use for energy purposes, in order to control man-made CO2 emissions. After having been greeted with enthusiasm at first, bioenergy is now met with … Read more

In the entire discussion on biotechnological rejuvenation, very few researchers ask the question why this should be a goal worth pursuing. In a series of articles (July 25, July 28 and July 31) we explore the potential of biotechnology to … Read more
Biotechnology has now reached the point that some researchers target rejuvenation as their goal, ultimately in humans. With a slight hint of immortality behind the horizon. But if we look more carefully, they are still far removed from those targets. … Read more
What will come after healthy aging? In biotechnology, advances have been so swift over the past few decades, that some scientists have started thinking of ways to tackle aging itself, that ultimate and fatal disease of mankind. Even with some … Read more
Imitating nature’s engineering secrets at the nanoscale could lead to a host of useful applications, like energy saving materials. Biomimicry, also called bionics, uses structures found in nature to solve everyday problems. A well-known example is the Velcro strip, which … Read more

The strongest biomaterial ever has been assembled recently by Swedish, American and German researchers; it consists of cellulose, properly speaking of carefully parallel oriented cellulose nanofibrils (CNFs). The material is stronger than steel, even stronger than spider silk, regarded as … Read more
In February, BP published a new Energy Outlook. The main difference with previous outlooks lies in its renewable energy forecasts. The previous ones were scandalously low. The company partly redressed this state of affairs, and even confessed that it had … Read more
These days, my inbox is overflowing with messages from concerned scientists warning that mankind cannot pursue economic growth forever; that it should deviate quickly from such a course, in order to prevent global environmental disaster. But as much as I … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
