This study examined various source-separating sanitation systems to evaluate their environmental performance, providing decision-makers with insights for selecting an appropriate system for a newly developed neighborhood in Sweden. A full consequential LCA was conducted to account for resource recovery and substitution. The local wastewater treatme...

The wake topology behind a wall-mounted square cylinder immersed in a turbulent boundary layer is investigated using high-resolution large-eddy simulations (LES). The boundary-layer thickness at the obstacle location is fixed, with a Reynolds number based on cylinder height ℎ and free-stream velocity 𝑢∞ of 10,000 while the aspect ratio (AR), define...

Photovoltaic groundwater pumping has the capacity to reduce carbon emissions of the agricultural sector in South-Asia but necessitates adequate financial and policy plans to develop its potential. To support the design of these plans, a numerical model that utilizes open-access data for simulating the pumping capacities of photovoltaic groundwater ...

A wave energy converter (WEC) comprises many components with distinct functions. The whole WEC system is complicated, as each component is also a complex subsystem. It is challenging to properly model and couple these subsystems to achieve a global simulation of the whole system. This study proposes an FMI-based co-simulation framework to tackle th...

Climate change with global warming represents one of the most significant challenges of our times. Achieving the objective of the Paris Agreement and limiting global temperature increase to 1.5 °C requires greenhouse gas emissions to decline to net zero by the middle of this century followed by negative emissions. CCUS (Carbon Capture Utilisation a...

Artisanal small-scale mining (ASM) significantly contributes to water pollution in many regions of the world, including the Prestea area in Ghana. This study comprehensively evaluates the surface water quality in the Asasre River, Prestea, a tributary of the Ankobra River, heavily impacted by ASM activities. The primary objectives were to analyse t...

The demand for cement has significantly increased, growing by 8% in the year 2022 and by a further 12% in 2023. It is highly anticipated that this trend will continue, and it will result in significant growth by 2030. However, cement production is highly energy-intensive, with 70 to 80% of the total energy consumed during the clinker formation, whi...

The energy sector is essential in the transition to a more sustainable future, and renewable energies will play a key role in achieving this. It is also a sector in which the circular economy presents an opportunity for the utilisation of other resources and residual energy flows. This study examines the environmental and social performance of inno...

The aim of this paper is to present a decision support system (DSS) to capture the complexity of the transition of a national energy system to net zero in the context of multiple sustainability themes. The paper proposes an integrated assessment framework that combines dynamic systems modeling, sustainability indicators, and multi-criteria decision...

Reducing emissions of the key greenhouse gas methane (CH4) is increasingly highlighted as being important to mitigate climate change. Effective emission reductions require cost-effective ways to measure CH4 to detect sources and verify that mitigation efforts work. We present here a novel approach to measure methane at atmospheric concentrations by...
