Promotores: Prof.dr.G.R. de Snoo and Dr. R. Heijungs

To contribute to the body of knowledge aiming at a better coverage of ecosystem service assessment in LCA studies, this thesis dives into the challenges of incorporating existing ecosystem service methods within the impact assessment phase of the conventional LCA framework.

The upscaling of Life Cycle Assessment (LCA) data is recognized as one of the main challenges in the ex-ante LCA of emerging technologies. This challenge arises since industrial-scale system specifications for these technologies are unknown and industrial data is lacking.

This thesis discusses several questions regarding the double ramification cycle as a Chow class on the moduli space of stable n-pointed genus g curves using tools from so-called logarithmic geometry.

LCA has become an important method to study environmental impacts of human activities. Still, there are several methodological issues in LCA that can adversely affect the results reliability.

A difficulty of studies on chemical kinetics are the reaction time scales and detection of their intermediates.

Enhancing social inclusion through developing methods and analytical tools for understanding and reasoning about such phenomena based on sensor data.

Researchers at LED3 are working together with biopharmaceutical company Galapagos to develop software for use in early drug discovery (funded by NWO). This software is able to design molecules with several simultaneously optimized characteristics and will also take prediction reliability into consideration…

Ce livre est une étude pionnière portant sur l’analyse conceptuelle et la traductibilité des termes de maladie dioula jusqu’ici non abordées par les recherches antérieures. Le Dioula est une langue mandé parlée au Burkina Faso. L’étude présente les représentations de la santé, de la maladie et du corps…

Mycorrhizas are symbiotic associations between soil fungi and most plant species.

Three major cosmology-focused missions are planned for the next decade: the Euclid space telescope, the Vera C. Rubin Observatory in Chile, and the Nancy Grace Roman Space Telescope.

The authors provide an approach for eliciting population’s preferences in order to calculate weights for use in the optional weighting step in Life Cycle Assessment.

How can an effective ‘Safe and Circular by Design’ method be developed for practical application in a designer’s context, particularly for the initial stages of product design, incorporating Safe-by-design strategies, LCA/LCT, risk assessment and ethics?

The car we buy is made out of thousands of components, which are produced using different types of materials. These materials need to be sourced from different places, sent to production facilities and assembled. Once the car is dismissed, the components need to be taken care of by either reusing, recycling…

Leiden University is 444 years old, and to celebrate 220 cyclists took to the saddle on 11 May and followed the new 44.4 km route around Leiden, The Hague and the surrounding area.

The research aims at achieving a European consensus on a harmonized LCA approach/framework to be applied in E-mobility sector. The research will focus on needs and gaps in current LCA practices in E-mobility and try to provide solutions for them based on the rich knowledge and experience represented…

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

Although the weather in the Netherlands will always be unpredictable, June might be the month to say with certainty that the temperatures will be pleasing enough for a ride on your bicycle. Aside from the benefits for your (mental) health, you will also make a positive impact on the environment. Start…

What mismatch of socioeconomic and environmental values is preventing Circular Collaboration in Dutch housing renovations?

The objective of this project is to fundamentally improve our understanding of the ways in which science progresses. Empirical studies have used bibliographic metadata to provide relevant insights, but these studies have failed to tell us how science progresses. Supported by computational advances and…

Advances in the field of high-performance Nd-Fe-B permanent magnets, by re-engineering their microstructure to make them more powerful while reducing rare earth content.

There is a need for alternative methods to replace, reduce and refine (3R) animal experimentation. Combining experimental data from high-throughput in vitro studies with in silico modeling is a promising approach to unravel the effect of chemicals on living cells and to gain a better understanding of…

Development & demonstration of low environmental impact innovation and optimization practices in pharma production.

The transition to electric vehicles (EVs) reduces vehicle emissions to combat climate change. EVs raise concerns regarding the production of lithium-ion batteries and related emissions; while batteries can also provide energy storage services for the electricity system.

Michiel Pronk defended his thesis on 30 March 2016

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.

Freshwater biodiversity has been threatened by eutrophication due to excessive nutrients in the environment. Releasing the freshwater species from such pressures requires efforts from industry and manufacturers to avoid emissions to vulnerable and high-risk regions.
