The social and environmental dimensions of global value chains
(Doctoral theses at NTNU;2018:341, Doctoral thesis, 2018)As the economy has become more globalized, labour and environmental impacts have been redistributed throughout the globe. Today, the complexity and fragmentation of global value chains mean that the distance between ... -
The Social and Environmental Sustainability in Photovoltaic Module Supply Chains
(Bachelor thesis, 2023)Behovet for fornybar energi øker raskt, og solenergi er i ferd med å bli den raskest voksende energibransjen i verden. Kina har majoritetsmarkedsandel for hele forsyningskjeden for solcelle paneler, fra utvinning av kvarts ... -
The socio-economic impacts of introducing circular economy into Mediterranean rice production
(Journal article; Peer reviewed, 2019)A novel bio-fertilizer technology that utilizing paddy rice residues (bran and husk) through composting was assessed in the context of life cycle assessment application to circular bio-economy. The bio-fertilizer can recycle ... -
The Sono-Hydro-Gen Process (Ultrasound Induced Hydrogen Production): Challenges and Opportunities
(Journal article; Peer reviewed, 2019)Producing hydrogen using sound waves offers tremendous opportunities, which could lead to a clean, affordable and reliable energy source. Introducing high-frequency sonic waves to liquid water could provide ... -
The spinodal of single- and multi-component fluids and its role in the development of modern equations of state
(Journal article; Peer reviewed, 2016)The spinodal represents the limit of thermodynamic stability of a homogeneous fluid. In this work, we present a robust methodology to obtain the spinodal of multicomponent fluids described even with the most sophisticated ... -
The Swedish Footprint: A Multi-model Comparison
(Journal article, 2018)Sweden has a large per capita carbon footprint, particularly compared to the levels recommended for maintaining a stable climate. Much of that footprint falls outside Sweden's territory; emissions occurring abroad are ... -
The swing adsorption reactor cluster (SARC) for post combustion CO2 capture: Experimental proof-of-principle
(Journal article; Peer reviewed, 2018)This paper presents the first experimental demonstration of the novel swing adsorption reactor cluster (SARC) for post combustion CO2 capture. The SARC concept combines a temperature and vacuum swing for sorbent regeneration. ... -
The techno-economics of biocarbon production processes under Norwegian conditions
(Journal article; Peer reviewed, 2017)This work deals with techno-economic analysis studies in the context of production of various grade biocarbon for utilization as reducing agents in metallurgical industries. A detailed process design was developed for wood ... -
The transition in settling velocity of surfactant-covered droplets from the Stokes to the Hadamard–Rybczynski solution
(Journal article, 2017)The exact solution for a small falling drop is a classical result by Hadamard and Rybczynski. But experiments show that small drops fall slower than predicted, giving closer agreement with Stokes’ result for a falling hard ... -
The transition to renewable energy technologies-Impact on economic performance of North Rhine-Westphalia
(Journal article; Peer reviewed, 2019)The economic impacts of the German Renewable Energy Act (EEG) are of considerable importance for the discussion of the energy transition in Germany (Energiewende). The Energiewende implies structural changes of the energy ... -
The uncertainty of consumption-based carbon accounts
(Journal article; Peer reviewed, 2018)Consumption-based carbon accounts (CBCAs) track how final demand in a region causes carbon emissions elsewhere due to supply chains in the global economic network, taking into account international trade. Despite the ... -
The Use of Active Grids in Experimental Facilities
(Chapter, 2019)Active grids allow for the turbulence in experimental facilities to be tailored through a broad range of turbulence intensities and Reynolds numbers. This work provides an overview of the active grids that presently exist ... -
The Use of ExPAnD in Cyclic Low Temperature Processes
(Master thesis, 2011)The pinch analysis method has been applied to different processes successfully for heat integration. Since it does not include pressure as a factor in low temperature processes and it has important role in those processes, ... -
The Use of Power Ultrasound for the Production of PEMFC and PEMWE Catalysts and Low-Pt Loading and High-Performing Electrodes
(Journal article; Peer reviewed, 2019)This short review paper highlights some of the research works undertaken over the years by Pollet’s research groups in Birmingham, Cape Town, and Trondheim, in the use of power ultrasound for the fabrication of low temperature ... -
The Use of Ultrasound for the Electrochemical Synthesis of Magnesium Ammonium Phosphate Hexahydrate (Struvite)
(Journal article; Peer reviewed, 2019)With the observed global intensification of the agricultural sector, slurry management has now become a severe problem causing a large amount of pollution due to industrial fertilizers. It is imperative that techniques are ... -
The “Bad Labor” Footprint: Quantifying the Social Impacts of Globalization
(Journal article; Peer reviewed, 2014)The extent to what bad labor conditions across the globe are associated with international trade is unknown. Here, we quantify the bad labor conditions associated with consumption in seven world regions, the “bad labor” ... -
