The Grachtwacht (Canal Watch) conducts research on urban wildlife and the impact of plastic on nature. With our clean-ups, we not only collect waste, but also data. This way we try to find out the source of the waste and turn off the tap on shore. This way there is structurally less plastic in the c…

At the entrance of the Van Steenis building you may now visit an exhibition on material culture. Unexpectedly, it does not display pottery or tools, but building materials. And recent ones at that! Check out the exhibition on Legos lost at sea, conceived and assembled by PhD candidate Maia Casna. ‘These…

Mapping out the problem of plastic pollution requires a lot of data over a large area. That's why scientists are increasingly turning to volunteers for help, also known as citizen science. But what are the challenges for a researcher when he or she involves the public in research in this way? Four Leiden…

Plastics are an intrinsic part of our society. Annually, 400Mt of plastics are produced of which roughly 40% is discarded within a year.

Microplastics are small pieces of plastic found in the environment. At CML research have been conducted in the distribution of these plastics on beaches around the world using citizen science. In addition, CML is conducting in depth case-studies in the Caribbean and along the Dutch coast. Follow-up…

Auke-Florian Hiemstra is the Leidsch Dagblad Person of the Year 2022.

The world is becoming clogged with plastic, with tiny plastic particles found everywhere, from the oceans’ depths to the mountain tops, soil, plants, animals and even inside us. The question is: what harm, if any, are they causing? In a new article on The Conversation, environmental scientists Meiru…

Nanoplastics can accumulate in developing hearts, according to a study by biologist Meiru Wang from Leiden University. Her research on chicken embryos sheds new light on how these tiny plastic particles pose a threat to our health.

This paper focuses on the legal and institutional assumptions of Fritz Scharpf's famous thesis of an asymmetry between positive and negative integration in the EU. Taking issue with a number of arguments forwarded in the lead piece for this debate section, it questions the relevance of the thesis to…

The Court of Justice of the European Union is facing renewed scrutiny after expanding the reach of Article 2 TEU in Commission v Hungary.

This year Leiden University exists for 444 years! This will be celebrated together with the residents of Leiden and The Hague during various activities. One of these is scientists and residents doing research on plastics and psychology together.

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…

Four Master's students Science Communication & Society made two podcasts on the theme Plastic for the end project of their study programme. With the podcasts, they helped the Institute of Biology Leiden (IBL) to draw attention to plastic pollution. And that was harder than it seemed. 'Be sure to test…

In this project we ask: how does pollution manifest as part of different practices, both socially and materially.

Join the Pipe is a project committed to reduce plastic waste and to provide people both in the Global South and in the Global North with drinkable water.

How dangerous are micro- and nanoplastics? Do they affect the environment? What harm can they do to our bodies? Questions that we can now finally answer because of Fazel Abdolahpur Monikh. Together with his colleagues, he developed a method to detect and quantify nano-sized plastics. Their paper has…

The cargo lost at sea as a result of the MSC Zoe disaster should be considered environmental pollution and information about it should be made public. This was the case made by Leiden Law School’s Leiden Advocacy Project on Plastic (LAPP). Following their investigation, the government has finally decided…

From where litter ends up to which languages are spoken in Leiden and The Hague: over 50 interesting, surprising, complex and entertaining questions were sent in for the Citizen Science project to mark our 444th anniversary. Not one but two Citizen Science projects will be starting this year in Leiden…
