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,...

Prospective life cycle inventory datasets for conventional and hybrid-electric aircraft technologies

Hybrid-electric aircraft represent a promising solution for the urgent need to decarbonize short-haul flights and bolster aviation sustainability. Nevertheless, the realization of hybrid-electric aircraft demands rigorous environmental impact analysis, given the substantial investments, time, and research required for technology development....

Redesign of Ultrasound Gel Bottle: A Systematic Sustainable Solution for the Radiology Department at the Leiden University Medical Center

Radiology department at the Leiden University Medical Center (LUMC) aims at preventing ultrasound gel waste of leftover ultrasound gel in the bottle and reducing the waste of plastic gel bottles. The study identified a critical environmental issue – the excessive use of disposable plastic ultrasound gel bottles in hospitals – and undertook a...

Data implementation matters: Effect of software choice and LCI database evolution on a comparative LCA study of permanent magnets

Life cycle assessment (LCA) databases and software evolve. We analyzed to which extent software and evolving life cycle inventory databases affect the comparison of technology alternatives, using a comparative LCA on permanent magnets as a case study, with two selected software tools: CMLCA and Brightway LCA. We migrated the system models...

Recovering critical raw materials from end-of-life multi-junction III-V/silicon solar cells: A criticality assessment of gallium, indium and silicon for large scale production of multi-junction III-V/silicon solar cells and an assessment of the environmental impacts and economic feasibility of recycling end-of-life multi-junction III-V/silicon solar panels

This thesis studies the criticality of gallium, indium and silicon for a 1GWp production of III-V/silicon solar cells and assesses the environmental impacts and economic costs \& benefits of a recycling process for these solar cells. III-V/silicon is an emerging solar cell technology, that is expected to enter the market in between 2025 and...

Sustainability criteria and the bio-based materials sector in the Netherlands

Fossil fuels will run out in the foreseeable future. Out entire economic system is build upon fossil fuels and building up another base for this economic system is challenging. The only alternative for making materials that normally are derived from fossil fuels is the Bio-Based Economy. Materials in this way get made from biomass, such as sugar...

A Visual Life Cycle Analysis - for architects and policymakers

The impact of urbanizing 400 million people in China in 20 years - a comparative analysis of common structural materials with bamboo as a promising alternative for (semi) high-rise developments. Transport, End of Life scenarios and Lifespan are essential factors in a Life Cycle Analysis (LCA). The Building Energy Use itself is becoming less...
