Mitigating suspended-sediment environmental pressure in subsea engineering through colliding turbidity currents

Turbidity currents have extensively been explored in quiescent environments. However, during several underwater activities (e.g., dredging and deep sea mining), generated turbidity currents could travel in opposite directions and interact with each other, which could largely influence their hydrodynamics and sediment transport capacity....

Sustainability Integration in Engineering Practice: A Comparative Life Cycle Assessment Study for the Case Study of a Wing Rib

Having seen exponential growth in demand for air travel, the aviation industry has found itself trying to find a balance between economic growth, technological development, and environmental sustainability. This saw a shift in attention towards materials such as fiber reinforced composites, predominantly thermoset in the past with higher...

Reducing the environmental impact of distribution centres: Designing green-enveloped biobased alternatives to compare with reference steel and concrete designs

The climate emergency calls for a global shift towards a low-carbon economy, to preserve natural resources and biodiversity, while limiting global warming and its consequences. This project focuses on the impact of distribution centres, intended for the storage of commercial goods. Warehouses are characterised by large flexible spaces and simple...

Mirror, mirror on the wall which is the greenest of them all? A critical comparison of chemo- and biocatalytic oxyfunctionalisation reactions

This review article critically compares two widely used types of catalysis, chemo- and biocatalysis, and provides insights on their greenness according to specified parameters. A comparative analysis of the environmental impact of chemo- and biocatalytic oxyfunctionalisation reactions based on published experimental data reveals that both...

High-quality reuse of materials in the building sector: A Research into the possibilities for reuse of monolithic- and hollow core slab floors coming from office buildings with a construction date between 1970 and 1990 in the new construction of serial housing

Waste generation is one of the main environmental problems and is a result of the current linear economy. Materials/elements are used whereafter they are wasted which is a problem considering the finite material supply on earth. Therefore, the current linear economy needs to move towards a circular one in which materials are reused and thus kept...

Comparative life cycle assessment of thermoplastic and thermosetting CFRP in aerospace applications

This work quantifies and compares the environmental impact of a thermoset CFRP aircraft skin panel to that of a thermoplastic CFRP panel. This comparison is done using a cradle to gate life cycle assessment including impacts from raw material extraction, manufacturing and end of life. In addition, a hotspot analysis was performed to identify...

Minimizing Environmental Impact of Cruise Flights using Meta-heuristic and Optimal Control Optimizations

Aviation has a negative impact on the environment. As the number of flights is expected to increase, the total environmental impact of aviation will continue to worsen. New solutions are required to mitigate these effects. Aircraft Trajectory Optimization For Environmental Impact (TOFEI) can help reduce the impact of aircraft pollutants while...

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,...
