Unlike the global north, most developing countries have difficulties affording sophisticated industrial machinery. Predictable economic conditions for their funding are just not easy to find. That's why the waste management options I presented in last week's article are not really much of an option outside the OECD. Even for some OECD members, they're far from posing a realistic alternative to the...
Reduce, Reuse, Recycle – the waste imperative is as clear as it can get. What's less clear, however, is what we should we do with the remaining stuff. Even the greenest society is, at a certain point, confronted with the unusable leftovers of consumption. What should happen to these? Treatment of the leftovers is a well discussed question and the answer relies on three big alternatives: incineration, dumping and composting. All three have pros and cons, some of which are apparent, others rather surprising. In this article, let me introduce you to a life cycle assessment (LCA) that analyzes th...
It’s international Students‘ day today. This day has a long history as well as impacts and scale of student movements. As some kind of intellectual nucleus these movements are often a source for fundamental changes. The International Students’ Day has its origin in the late 1930s as Prague university students rebelled against the National Socialists.

In Germany students and pupils from vocational colleges will protest against the current educational system and the bad cond...
It is no secret, that the Earth's resource base is on a declining track. In the 1970s, the Club of Rome started to rivet public attention towards "natural resource restrictions" - we all remember the legendary "limits to growth" (also see its 30-year update [PDF]), a corner stone of sustainable development. Some of the well-established industrialized countries have become a little greener since then. However, in the course of the last 20 years, a number of emerging economies joined us in their hunger for raw materials. As a consequence, we face an increase of resource scarcity. Economically s...
