On paper it is recycled, but in reality enormous quantities of plastic waste from the Netherlands end up in Asian seas. Researchers from the Leiden Institute of Environmental Sciences charted the fate of plastic food packaging waste from the Netherlands. They published their results on July 8 in the…

Roberto Arciero is part of RESPIRE project (Research Educational and Storytelling Project in Italian Remote Ecosystem), an international and interdisciplinary research team led by Martina Capriotti (University of Camerino) that received the National Geographic Meridian grant. Among the different topics,…

Leiden PhD candidate Jo-Anne Verschoor discovered that nearly twenty percent of the bacterial strains she studied could degrade plastic, though they needed some encouragement to do so. ‘Bacteria are just like people,’ says Verschoor. Her research was published in the journal Communications Biology,…

International trade has played a major role in defining the modern global economy. Trade, however, entangles the environmental pressures of economic sectors, giving the illusion of environmental improvements, while the opposite may be occurring.

Shell, our country's largest company, is constructing a vast plastics plant in the United States. And it is doing so at a time when the European Union, led by the Netherlands, is launching a major pact to combat use of plastic.

On Friday 8 February, the first Plastic Avengers Conference took place in Amsterdam. Initiator Merijn Tinga, the Plastic Soup Surfer from Leiden, brought together ‘independent plastic fighters' to arrive at a manifesto against plastic pollution. The Leiden Advocacy Project on Plastic was also invited…

Nanoplastics influence the behaviour of larval zebrafish, says new research by the Institute of Biology Leiden (IBL) and the Institute of Environmental Sciences (CML). The researchers observed that a certain type of nanoparticles leads to stress reactions in the sugar balance, resulting in hyperactivity…

A political-legal study of rights invocation by pollution victims in China and Indonesia

How does invasive hybridization affect threatened native species?

What motivates citizens to participate in a citizen science project on plastic pollution? And does that motivation change over time? Liselotte Rambonnet tried to answer these and other questions with her research on the Clean Rivers (‘Schone Rivieren’) project. Rambonnet is a PhD student at the Institute…

Merijn Tinga, the Plastic Soup Surfer, launched the Pick Up 10 campaign. This campaign, supported by Google and National Geographic, uses photo recognition to identify and monitor litter through an app.

What are the effects of light pollution from cities and bridges and noise pollution from passing vessels and nearby road traffic on migratory fish passage and spawning in rivers?

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…

Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.

Below you will find an overview of the publications of The Leiden Advocacy Project on Plastic.

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

What is the influence of the 2016 ban on free plastic bags on the environment? Industrial ecologist Stefano Cucurachi received a LUF grant of €75.000 to answer this question.

A group of biology students are working on a solution to the world’s plastics problem by getting bacteria to make biodegradable plastic.

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.

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…

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 a new series of articles, we explore how the humanities study topics related to sustainability. First up: waste. How and why study waste as a humanities scholar? We asked Elena Burgos Martinez, University Lecturer South and Southeast Asian Studies, and Katarzyna Cwiertka, Professor of Modern Japan…

After years of lobbying by environmental activists, a deposit scheme for small plastic bottles is to be introduced on 1 July 2021. One of the leaders in the fight is alumnus Merijn Tinga. The university will have collection points for plastic bottles and is also supporting the Plastic Spotter citizen…

On 17 October 2019, Laure d'Hondt defended her thesis 'Addressing Industrial Pollution in Indonesia. The Nexus between Regulation and Redress seeking'. The doctoral research was supervised by prof. A.W. Bedner and dr. J.A.C. Vel.

The sand on European beaches may look pristine, but in every kilogram of sand there are on average 250 microplastics: fragments smaller than 5mm. These results are part of a study from Leiden researchers with the help of beach-goers throughout Europe.

Leiden academics Remco Breuker and Auke-Florian Hiemstra stand to win the title of Person of the Year.

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 Plastic Soup Foundation and Parley for the Oceans hosted the very first Plastic Heath Summit in Amsterdam on 3 October, covering the most relevant and pressing health concerns surrounding plastics and human health. Beyond discussing the latest findings in the field we asked the urgent question:…

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…
