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 … Read more
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. … Read more
It is an unfortunate fact that clothes, even those made of organic, low impact or recycled materials, are often not reused or recycled themselves. The majority end up in landfill or are incinerated. Inspired by the recently launched partnership of … Read more
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 … Read more
In the early days of renewable energy development, its adversaries would tell the world that renewable sources would be hopelessly inadequate. Traditional (fossil and/or nuclear based) systems would be indispensable because we would also need energy when the wind wouldn’t … Read more
The solar industry is in turmoil. The price of solar panels falls continuously and each year demand grows by 30%. This poses a major challenge to an industry that is quite sizeable already, with an expected turnover of some $ … Read more
Solar energy (photovoltaics, PV) is no longer that cute but hardly relevant technology of energy supply – it will evolve into the basis of our entire energy system. The world will have to take another look on PV: adapt itself … Read more
In three columns, I have investigated the question of bee colony collapse and neonicotinoids (neonics), the effect of pesticides on pollinating insects and natural pest predators, and finally the services that biodiversity renders to agriculture and the economy. I observed … Read more
In the first two columns in this series, I pictured the difficulties in establishing the truth on neonicotinoids (or neonics) and their effects on pollinating insects. The stakes are high. Neonics represent one third (in monetary value) of all insecticides … Read more
Neonicotinoids tend to have a detrimental effect on bees and other pollinating species – unsurprisingly so, because these ‘neonics’ (at a much higher concentration) are designed to kill insects. But it appears very difficult to gather solid evidence of adverse … Read more
As the struggle around neonicotinoids in the European Union is nearing a decisive phase, and my mailbox becomes overflown with panicky messages from both sides, I decided to make up my mind as to the truth of bee colony collapse: … Read more
Two factors are underrated again and again in energy policy: the potential of better energy efficiency (check here) and that of renewable energy. In our first column, we saw that important forecasters overestimate demand growth. We foresee global energy growth … Read more
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. … Read more
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 … Read more
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 … Read more
Sustainable construction requires a team, says Daan Bruggink. These ‘construction teams’ (project partnering) are not a new concept, but they are still used far too little. You need each other’s knowledge. The designer is not responsible for the construction and … Read more
Daan Bruggink is one of the standard bearers of sustainable architecture in the Netherlands. If anything, he insists on building based on nature: ‘We at ORGA Architects first consider natural forms,’ he says. ‘Second, we consider natural techniques such as … Read more
At the Bio-Based Products World conference, in March in Amsterdam, two speeches struck me as particularly relevant to our times: that of Tom Domen (Ecover) and of Caroline Laurie (Kingfisher). Both companies are in the consumer market, and seem to … Read more
One of my favourite blogs, grist.org, ran an article this week on a subject so far completely unknown to me: gene drive. A subject of major importance that should be discussed by all our readers. Or would it be another … Read more
Phosphorus is an essential ingredient of life on earth. It is a component of DNA and of bones, and it fulfils a key role in energy transfer in living cells. Yet it was regarded as an evil element after its … Read more
The launch of a new macroeconomic scenario study marked the opening of the ECO-BIO conference in Rotterdam today. Biorenewables fulfil a key role in climate policy and in future economic development, says the LEI/Copernicus report, concentrating on the Netherlands. In … Read more
Roundup, scientifically called glyphosate, is the most widely used and most widely criticised weed killer. Official studies find over and again that the agent is not very toxic to humans and animals; but there is a stubborn undercurrent that links … Read more
We all know the stories about DDT, fifty years ago – but did we learn from them? Not quite, says Ton Schoot Uiterkamp, a retired – but still very active – professor in environmental sciences at Groningen University. He has … Read more
In discussions on genetic modification, the name Monsanto invariably produces much controversy. Both its critics and its proponents can be very emotional. We will argue that Monsanto has taken the wrong turn in green biotechnology. This is the second article … Read more
In preparation for Paris 2015, the new major climate summit, researchers publish many scenarios on the reduction of greenhouse gas production. Over the years, these have become more pessimistic. As the world longer postpones adequate measures, it will have to … Read more
Microplastics are a major source of water pollution. The litter found in oceans and inland waters is dominated by plastics. This litter does not only consist of large items like plastic bottles and bags, it also contains microplastics if only … Read more
Nothing is wrong with genetic modification and its application in agriculture (green biotechnology), says Rudy Rabbinge; agriculture needs innovation, and GM technology is helpful in that because it allows us to operate faster and more precisely. But the business model … Read more
The enormous utility of polyethylene, polypropylene, polystyrene, polyvinyl chloride, and other polyolefins cannot be disputed, but their real cost is debatable. My teenage daughter makes cookies in our kitchen. The ingredients — flour, sugar, chocolate chips, etc. — are always … Read more
A decade ago, in an authoritative scientific magazine, we published a prediction (1) on the synthesis of complicated molecules, primarily medicines. We foresaw the integration of chemo and bio catalysis in a reactor that would also be the catalyst. A … Read more
Sustainability, the word has been used so often that some have been looking for alternatives for quite some time. But fortunately, the sustainability perspective often still inspires people; like in education, in view of the many courses, tracks, masters and … Read more
Last year, Ecover made a courageous decision. It decided to kick out palm kernel oil (widely known for its shaky sustainability) as a feedstock for many of its detergents, and replace it by a bio-equivalent oil produced by engineered algae. … Read more
Energy efficiency is our cheapest energy source, with a very large potential. It has been so for forty years and will probably continue to be so for decades to come. And yet, 99% of energy policy and energy debate is … Read more
How will Europe, the Netherlands in particular, earn its income in twenty-five years’ time, in a sustainable way? How do we prepare for the world of 2040? By green growth, based on the development of sustainable products and services. An … Read more
Members of Parliament. Gladly we present to your commission, on your request, our book Green Growth. Gladly, because we feel that our subject concerns everybody. That subject is: ‘how is the Netherlands, how is Europe, going to earn its income … Read more
They had come to Amsterdam by the dozens, to the Wind Energy Debate, to let themselves be heard. Opponents of wind energy. Their numbers and particularly their zest testified to it that the debate on wind energy has not calmed … Read more
Food supply should have absolute priority, no less so in a biobased economy. Says Rudy Rabbinge, emeritus professor in sustainable development and food security at Wageningen UR. That is why Rabbinge opposes biofuels from agriculture, but accepts biobased high-value products … Read more
Of course, a sustainable energy supply will depend primarily on the use of sustainable energy sources. But their intermittent availability requires major changes in the electrical grid. At all levels in the grid, from the individual household to the national … Read more
At present, we incinerate used car tyres, because recycling is too difficult. A new R&D program TREC, for which Michelin has established cooperation with the biotechnological company of Protéus, will have to change that. Tyre recycling, we can do it … Read more
Some communities declare themselves ‘shale gas free’. Pure symbolism. They know very well that they do not have a say in this. Apparently, they have the (naïve) idea that such a declaration will prevent environmental problems from shale gas recovery, … Read more
Our planet’s temperature rises. There is ample proof for that. CO2 emissions are the main reason, we know that for sure as well. We cannot deny that our wealth and craving for energy have caused this. But we can hardly … Read more
Glocal is the buzzword at Ecover: a term coined from Global and Local. Glocal also is the name of a major Ecover project, together with Forum for the Future, intended to sow the seeds for local production and local circular … Read more
We are at a turning point in the energy transition, particularly as to the contribution of solar power, says Wim Sinke. So far, the instrument for opening up markets was policy, but it has now become price. Solar panels have … Read more
When I was a child we often went on a holiday to France. To get us through the long journey we’d bring along small packages of apple juice, those with three in a wrapping and with shining foil to stick … Read more
As companies strive to be more sustainable, their customers might grow more critical on their performance rather than less, asking questions that were never raised. At least, that is what Ecover experiences. These bottles being made from sugar rather than … Read more
In this series, we discussed three design rules: reduce capital costs and create jobs, be lean on materials flows, and preserve structure. Our last guideline, elegance is beautiful, sums up the former three and enlarges them. Elegance in chemistry means … Read more
A biobased industry should not copy petrochemical industry’s structure: that structure has been optimised for over a century, for this particular feedstock. In order to compete, the biobased industry should particularly be lean on materials flows: it should use all … Read more
‘Often, sustainability is not merely better, but cheaper too. Sustainable technologies lend themselves to local systems with far lesser control costs. That is the basis for a technological transition with which the earth can feed as many as ten billion … Read more
Most people, when talking about a sustainable future for Europe, think in terms of energy supply. That is one-sided. It is true: the energy conflict still deepens, as the incumbent powers start to be challenged just recently, forty years after … Read more
Why on earth do we human beings have so much difficulty changing our thoughts – and our actions? For instance, change from a fossil economy to a green economy, from an inflexible hierarchical command society to a small-scale grass roots … Read more
In fifty years’ time, technology has changed from the bogeyman to the saviour of mankind. Large-scale and energy intensive processes used to be the pinnacle of technology, producing much collateral damage that was merrily cleaned up afterwards (it was all … Read more
