Integrated life cycle assessment and life cycle costing of concrete recycling in the Netherlands
Integrating life cycle assessment (LCA) with life cycle costing (LCC) offers the opportunity to simultaneously analyze the environmental and economic aspects of product alternatives, for the integration of which a unified computational has been proposed by Heijungs et al. (2013) [1]. The project aims…

Radio interview with Rene Kleijn about Urban Mining and Plastic Recycling
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.

Tiny clumps recycle themselves into complex structures
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…

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…

A smarter approach to energy and raw materials
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.

A load of old rubbish? What happens to the University’s waste?
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?…

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…
