Do e-waste workers display enhanced effects of adverse health effects due to informal e-waste processing in Nigeria? Is there a difference between the health outcomes of the exposed and the control groups? Are there difference in health effects within and between job groups (collectors, dismantlers,…

Vinasse is a major by-product generated by the sugarcane biofuel industry. It is a source of microbes, nutrients and organic matter and often it is recycled as fertilizer.

Recycling of post consumer plastic waste is problematic in that the environmental benefits are questionable and the costs are significant. It would be better to separately collect the most useful parts through the expansion of the deposit system.

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…

Besides being the author of such a classic work of literature as The Hobbit, Tolkien was also Professor of English Language and Literature in Oxford. How did he incorporate his research in his fiction? An international conference on the subject is being held in Leiden on 18 June.

Nederland Circulair! is organising the week of the circular economy, for the second time. This is a great setting for Leiden University to promote several of the university’s circular initiatives. We will kick off with an initiative by alumna Noortje Schrauwen: Raw material beachcombing.

Manufacturers produce high-end technology mostly top-down with large machinery, but small particles are able to build structures by themselves from the bottom up. A major challenge is that these particles easily clump together. Leiden physicist Daniela Kraft has developed a method to use this phenomenon…

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…

There have been recycling bins in all of the University buildings since 2018. Waste bins were removed from staff offices at the same time. Waste such as paper, batteries and printer cartridges is now collected in separate streams. But the big question is: what happens to the different waste streams?…

What are the life-cycle environmental impacts and risks to human health and ecosystems of a III-V/Si PV system? How can these be expected to change when the system is deployed at industrial scale? What are the most favourable recycling scenarios?

Over the past century, the world population has grown exponentially, as has our need for energy and raw materials. If we wish to continue to live prosperously in the future, we have to radically restructure our economy and consumption. Scientific research shows us how to do this.
