Report: what does our urban mine have to offer?
On 21 January, the Institute of Environmental Sciences (CML) has released two reports on circular economy and urban mining in the Netherlands. In them, together with Statistics Netherlands, they take stock of part of the Dutch ‘urban mine’: how much raw material can we reuse from the electricity grid,…

seinem Leben und Umfeld, seiner Vokalmusik und seinem praktischen Material zum Basso continuo-Spiel
The thesis presents a new perspective on Giovanni Girolamo Kapsperger (ca.1580-1651), who is nowadays only famous for his works for theorbo and lute, his remarkable output of vocal music of all genres being still mostly neglected from musicologists and performers.

Ancient populations pioneered the idea of recycling waste
The circular economy is typically seen as the progressive alternative to our wasteful linear economy, where raw materials are used to make the products that feed today’s rampant consumerist hunger, which are then thrown away. In a fascinating article, archaeologist Maikel Kuijpers reflects on the recycling…

Prehistoric hunters from the North Sea used human bones as weapons
Over the years, many spectacular archaeological finds have been washed ashore on the Dutch coast. Among these a large assemblage of barbed points made of bone and antler from the Mesolithic (11,000-8000 BC). The species used by Mesolithic hunter-gatherers to manufacture their barbed points remained…

Towards a liveable future
Humans have influenced nature since as early as the Ice Age, and over the past century man’s impact has become even greater with our many new technologies and a growing world population. Leiden researchers study this impact and how we can keep it within reasonable limits so that nature can be preserved.…

Ester van der Voet appointed professor of Sustainable Resource Use
The energy transition is already a huge challenge for society, but sustainable use of resources is even more complicated. Yet it is at least as urgent. Ester van der Voet has been working on it for decades, for example within the United Nations. Since February, she is a professor at the Centre for Environmental…

‘We are destroying our own planet' (and Latin America pays the price)
The whole world gets raw materials from Latin America, but at the expense of nature. Håvar Solheim researches the role of organised crime in this environmental crime and Soledad Valdivia researches sustainable urban initiatives in Latin America. What do these university lecturers think the future of…

Difficult message for policymakers from two Leiden reports on circular economy
You should start working now, and the positive results will only be seen long after your term has expired. That is just about the worst thing you can say to politicians and policymakers. Yet that is exactly the message of two recent reports on sustainable resource use from the Centre for Environmental…

Waste Separation
What is better for waste recycling: a plastic, paper or ceramic cup? A bio-based or fossil-based coating? Waste sorting at the source or at a recycling facility? Ask ten experts and you will get ten different opinions. We can all agree on one thing: doing nothing is not an option. Thus, Leiden University…

Invaluable bees and nature’s other services
We depend on nature for so many things: from clean water, wood and food to carbon absorption, water purification and coastal protection, as well as for relaxation, inspiration and identity. Nevertheless, our modern world putting increasing pressure on these ecosystem services. Leiden researchers investigate…

Dutch contribution to the development of African countries in the global value chain
Economies worldwide are increasingly interconnected; trade in raw materials and semi-finished products is increasing. Many products we use in the Netherlands originate abroad, and many products we make in the Netherlands are destined for other countries. Almost all countries around us participate in…

Materials made of self-spinning particles
Materials are either gas, liquid or solid, based on how their molecules respond to temperature and pressure. But what if the building blocks are self-spinning particles instead of ordinary molecules? Theoretical physicists found out what determines the phase of those artificial materials. Publication…

Maikel Kuijpers takes an archaeological perspective on the materials that shape our world
Materials like concrete, steel, plastic and fertiliser shape the world around us, but they’re also extremely polluting. If we want to build a more sustainable society, we can learn a lot from archeologists. How do we relate to these materials? And are there alternatives? Maikel Kuijpers is writing a…
