Arblaster, Thomas (author)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,...master thesis 2024

Deroo, Pepijn (author)For over 50 years, hydrazine has been the industry standard for monopropellant propulsion systems, widely used in satellite attitude and orbit control systems. However, hydrazine’s toxicity necessitates expensive handling procedures and may lead to a future ban of the propellant in Europe. This has motivated the development of novel...master thesis 2024

Verkammen, Marnix (author)With a continuously growing number of satellites in orbit, it becomes increasingly important to assess their impacts on the Earth's environment in a standardised manner. While interest in Life Cycle Assessment (LCA) for space missions has gained in strength in the past few years – particularly in Europe – no consensus has yet been reached on a...master thesis 2023

Arblaster, Thomas (author)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...master thesis 2023

Żarnowska, Agata (author)The current impact of the aviation industry on climate change poses little choice for aviation companies but to invest in sustainability. One way to do this is to develop and implement sustainable innovations in aircraft. However, the question is how it can be validated whether an innovation is sustainable. To do so, this research uses...master thesis 2023

Fadul Bonamusa, Mikel (author)Aiming to comply with the Paris Agreement, the reduction of Europe’s GHG emissions in the energy sector is a must. Due to the intermittency of renewable sources, energy storage technologies are essential to this plan. Offshore Low Head Pumped Hydro Storage (LH PHS) is presented as an alternative to partly solve this problem. Considering that its...master thesis 2023

Papavasileiou, Maria (author)Aviation is an important sector and one of the key contributors to today’s economy. With a forecasted annual growth rate of 4.4%, the sector is expected to expand even more in the coming years. This expansion is however followed by the environmental burdens aviation causes to the environment. Following the anticipated growth of the aviation...master thesis 2022

Boyce, Johanna (author)Using the IEA Ammonia Roadmap aligned with the IMAGE electricity scenarios, an extensive database was produced allowing for prospective LCAs across three storylines from 2020 to 2050 (SSP2-Base, SSP2-RCP26, SSP2-RCP19). The scenarios correspond respectively to 3.9, 2.0, and 1.5°C of global warming in 2100 (vs. pre-industrial levels). Regionally,...master thesis 2022

Kumar, Sanjay (author)The goal of this graduation project was to investigate if 3D printing could serve as a promising alternative for manufacturing spare parts needed for the re-manufacturing of diesel injection pumps. This project was conducted under the EU ReCiPSS project, along with the support of Robert Bosch GmbH. The proposition was investigated on three...master thesis 2022

van Bodegraven, Martijn (author)The capture of carbon dioxide before or after it is emitted has been regarded as a crucial mitigation pathway to prevent the rapidly increasing accumulation of CO2 in the atmosphere. The valorisation of the captured CO2 into value added products such as methanol provides an additional economic incentive to continue developing these technologies....master thesis 2021

Nijman, Marit (author)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...master thesis 2021

Gurdal, Irem (author)With the current trend in emissions, the pH levels of the oceans are expected to decrease from 8.1 to 7.8 by the end of the century. In combination with the other stressors, it is projected that OA will have a wide range of impacts on marine life and its services to humanity. The representation of these implications is limited in environmental...master thesis 2021

Lensen, Sietske (author)Life Cycle Assessment (LCA) models are inherently uncertain due to the model structure interacting with the model inputs and modeling choices. The methods of sensitivity analysis (SA) aim at retracing the causes of the uncertainty of the results of a model. This work takes apart the methods of uncertainty propagation, SA, and LCA, and identifies...master thesis 2021

Ingemarsdotter, E.K. (author)The concept of a ‘Circular Economy’ (CE) has been gaining traction in business, policy, and academia. It envisions an economy powered by renewable energy in which the value of products and materials are preserved for as long as possible. ‘Design for Circular Economy’ is emerging as a research field as well as a branch of sustainable design...doctoral thesis 2021

van Sice, Corrie (author), Faludi, Jeremy (author)Metal additive manufacturing (AM) is revered for the design freedom it brings, but is it environmentally better or worse than conventional manufacturing? Since few direct comparisons are published, this study compared AM data from life-cycle assessment literature to conventional manufacturing data from the Granta EduPack database. The...journal article 2021

van Lier, Stefan (author)This research focuses on identifying and evaluating ways to improve the sustainability of solid waste management (SWM) in semi-public spaces using the Efteling theme park as a case study. To the best of the author’s knowledge, this study is the first to apply an integrated waste management approach to optimize SWM in this context. The approach...master thesis 2020

van Wijnen, Wouter (author)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,...master thesis 2020
