Life cycle sustainability of novel monopropellant systems: A comparative LCSA of a LEO minisatellite case study

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...

Consensus-based single-score life cycle assessment for space missions

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...

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...

Measuring the environmental impact of a livestock feeding robot life cycle

The pursuit of sustainability is at the forefront of international conversation in an era marked by urgent environmental challenges. This research aims to shed a light on tools, indicators, and methodologies used to assess sustainability, paving the way for informed decisions, actionable insights, and a brighter tomorrow. <br/><br/>The Paris...

Sustainability Assessment of a Sustainable Innovation for the Aviation Industry: Case Study of Bio Composites for Aircraft Interiors

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...

Life Cycle Assessment of Offshore Low Head Pumped Hydro Storage

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...

Circular Strategies Enabled by the Internet of Things: Opportunities, Implementation Challenges, and Environmental Impact

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...

Comparing environmental impacts of metal additive manufacturing to conventional manufacturing

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...

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,...

A review of Absolute Life Cycle Assessment methods and applications: And their potential for benchmarking absolute product-level contributions to the UN Sustainable Development Goals

As of 2016, governments globally adopted the task to achieve social, economic and environmental sustainability by committing to the targets from the UN Sustainable Development Goals (SDGs). The SDGs incorporate a set of 17 goals and 169 targets accompanied with more than 200 indicators that can guide towards achieving sustainable development by...

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%...

The environmetal impact of a solar powered CO2 to methanol farm

Zero Emission Fuel (ZEF) has the goal to create affordable high-grade methanol, produced from absorbed carbon dioxide and water from the air. The methanol is produced in a solar methanol (MeOH) farm, consisting of 13225 micro-plants which are powered by PhotoVoltaicsolar panels (PV panels). The solar capacity of the solar MeOH farm is 12 MW and...

Sustainable structural design of high-rise: Life-cycle assessment of main load bearing structures of high-rise buildings in the Netherlands

High-rise buildings are a potential solution to the environmental impact caused by the built environment and the increasing demand for space in urban areas. As recent developments focus on reducing the impact by operational energy (OE) (heating, cooling, hot water and ventilation during use phase), impact by the embodied energy (EE) (production,...

Conceptual design of a demountable, reusable composite flooring system: Structural behaviour and environmental advantages

There is currently increasing interest in making a transition towards a circular economy, to improve resource efficiency and to reduce harmful emissions to the environment. The European Union adopted a Circular Economy package in 2015, while the Dutch government introduced a programme to achieve a circular economy by 2050. The construction...
