Hydrogen-based fuels for European aviation: A prospective life cycle assessment applying scenario analysis

Through exploratory scenario development, this study delves into the environmental impacts of European commercial aviation. Climate targets and the adoption of alternative aviation fuels (AAF) following ReFuelEU Aviation are assessed, considering e-fuel produced from direct air capture (DAC) and hydrogen aircraft. A novel method is applied,...

Environmental trade-offs of aerostructures: A prospective lifecycle assessment of wing ribs

Emerging in the domain of composite manufacturing, thermoplastic polymers can enable the reduction of process times, costs, and waste. In this study, lifecycle assessment (LCA) is used to evaluate a design for a carbon fibre-reinforced thermoplastic (CFRTP) wing rib, made from carbon fibre and polyetherketoneketone (CF/PEKK). The CF/PEKK rib is...

The environmental impact of structural elements made of concrete compared to timber: A case study of terraced housing in the Netherlands

This research tries to answer the question which construction material, concrete or timber, is best to use during the construction of terraced housing in the Netherlands, based on the environmental performance. Existing studies often do not take all aspects of a design for the comparison into account, or have a bias toward one material. In order...

Sustainable timber structures: Quantitative research evaluating the potential effects of carbon sequestration and cascading strategies in the Netherlands based on a comparison of the Dutch and European life cycle assessment methodologies

To meet the climate goals set by the government, the building sector needs to reduce its contribution to the environmental burden on society. However, the current situation in the Netherlands presents a major challenge to build more to reduce the housing shortage, while at the same time reducing its environmental footprint. Therefore,...

Improving the environmental impact of the washing machine product-service system by Coolblue

In 2019 over 670000 new washing machines(WMs) were purchased in the Netherlands (Statista, 2020). With a WM ownershiprate of 98%, the Dutch people have one of the highest WM ownership percentagesin the world (Laitala et al., 2018). In the traditional business model (BM)these WMs will be used, discarded and recycled. In order...

Including the Effects of Artificial Light at Night on Moths in Life Cycle Impact Assessment

The aim of this research is to implement the effects of artificial light at night on moths in a model that functions as an impact category in the life cycle assessment methodology. The model defines the attraction of moths in a specific region of influence. This attraction might result in multiple direct and indirect effects that could lead to...

A decision support model for analysing the reuse potential of hollow-core slab floor components

This thesis ‘A decision support model for analysing the reuse potential of hollow-core slab floor components’ describes the development of a decision support model to investigate the reuse potential of a structural building component. For this research, the hollow-core slab floor component is chosen as the structural building component to be...

When energy savings become a waste: How the environmental- and energy performance requirements of buildings can stimulate the building industry towards sustainable design of office facades in the Netherlands

The life cycle of a building has a tremendous impact on the environment. This is due to its energy demand, production and transportation of building materials, and its maintenance. Actually, the building industry is one of the most polluting industries that contribute to climate change. In the Netherlands alone, this sector is chargeable for 50%...

Quantifying Life Cycle Environmental Benefits of Circular Steel Building Designs: development of an environmental assessment tool for reuse of steel members in building designs for the Netherlands

The re-use of building components and structural elements is an underdeveloped practice which could be an important strategy in the global paradigm shift towards a circular economy. Steel is one of the most important structural building materials which combines incredible strength, favourable mechanical properties and excellent durability...
