A common sense energy scenario. Part 1: global energy consumption
Two factors are underrated again and again in energy policy: the potential of better energy efficiency (check here) and that of renewable energy. In Paris, world leaders have affirmed their intention to restrict global warming to 2 oC or less. In order for this to become true, global energy consumption needs to level off and
Biobased economy strategy: through specialty chemicals and materials
The European biobased economy strategy should not lead through drop-in chemicals. The key is in Smart, Small and Clever. This is the second of two columns on the European biobased economy strategy, published on 23 October and 27 October 2016. New value chains The present European biobased economy strategy, that heavily depends on biofuels, has
Drop-ins lead the biobased economy astray
Earlier this year, German nova-Institute published another thoughtful document on the biobased economy. It starts out from the observation that ten years of European policy making have not been very successful. The amount of biomass used in the European chemical and plastics industry has stagnated. The only sectors showing growth are the bioenergy and biofuel
Plastic litter: strict regulation is the only remedy
Plastic litter is a curse. According to Joan Hanegraaf, the only solution to this problem is strict regulation and enforcement. Look at Japan, Canada, Singapore. No plastic litter there. One would not even dare throwing a away a stub of a cigarette, for fear of being fined severely. It’s the only way out. We talked
Biobased means thinking in short cycles
Biobased really is a sub-branch of circular, says Daan Bruggink of ORGA architects. The circular economy knows two cycles, technical and biological. The biological cycle of course contains the ‘real’ natural materials: wood, reed, fibre, flax, and so on. Technical materials such as foam are often fossil-based. We should reuse or recycle 100% of these
Teaching sustainability in secondary education
Last year, at the symposium Het Groene Brein Roots!, I met a Programme Coordinator from the teacher training course at Rotterdam University of Applied Sciences, RUAS. He mentioned that he was working on a project on teaching sustainability, in order to integrate sustainability into the secondary education curriculum. At the time, I was also working
Sustainable materials need certification and lobbies
Sustainable materials need to get certified, says Daan Bruggink. The architect is convinced that project developers will switch to more sustainable materials by including them in certification. At present, energy is already drawing much attention, says Daan, and that is why everyone (in the Netherlands) is building energy-efficiently. Similarly, sustainable materials will take a large


















Gaia, and James Lovelock’s gentle revenge
In his book The Revenge of Gaia (2006) James Lovelock reasserts his idea that the earth, living and mineral, is a self-regulating system. A system that is now put to an extreme test by mankind by the vast amounts of CO2 we pump into the atmosphere. Lovelock argues with great mastery of his subject; but
