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?

A framework for prospective/ex-ante life cycle assessment (LCA) and ecological risk assessment (ERA) of emerging technologies is developed and applied to a case study of III-V/silicon photovoltaic panels.

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.

Some examples of research questions include: What framework of circular strategies should local practitioners use? How should practitioners organize their monitoring of the circular economy activities in the region of interest? What are the main products that have the most circular potential in the…

Co-ordination Action for Innovation in Life-Cycle Analysis for Sustainability: deepening, broadening and leaping forward the LCA methodology.

CMLCA is a software tool that supports the technical steps of the Life Cycle Assessment. The focus of the program is on advanced computational aspects of life cycle inventory calculations.

How to bring together different footprints into an integrated family and what are the synergies? What are the roles of inventory analysis and characterization in measuring individual footprints and how these affect a footprint family? How to benchmark environmental footprints against related planetary…

How can we develop and further improve life cycle impact assessment methods, characterisation factors and normalisation factors?

In-use stocks of products can be considered as intermediaries between human needs and the physical world.

What is the environmental impact of different waste collection systems across Europe? How can the collection be improved when considering collection, sorting, and treatment, as well as use options for secondary materials?

Examining the sustainability aspects of biotechnology, especially those related to the production of ethanol from biomass.

What is the role of the rebound effect in achieving environmental savings from transport eco-innovation? Are traditional definitions of the rebound effect adequate in the context of transformative innovations and multidimensional environmental issues?

A critical look at the impact assessment modelling of metals in Life Cycle Impact Assessment and improvement options.

Decarbonizing the building stock is critical for realizing the climate-neutral target for the Netherlands.

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.

What would be the environmental performance of the Carbon4PUR technology at industrial scale in the future?

De auto die we kopen is gemaakt van duizenden componenten, die weer gemaakt zijn van verschillende typen materialen. Deze materialen zijn op zichzelf weer afkomstig van verschillende plekken, worden naar productiefaciliteiten gestuurd en verzameld tot een product. Zodra de auto afgedankt is, moeten…

Hoe kunnen we onze maatschappij zo inrichten dat de wereld leefbaar blijft voor onszelf en al het andere leven om ons heen? Aan dat vraagstuk werken Leidse wetenschappers samen vanuit allerlei disciplines, van biologie tot datawetenschap en van milieueconomie tot archeologie.
