Preface: Establishing assembly and production facilities has traditionally constituted the possibility for companies to avoid high import duties, or a possibility to establish themselves in free-trade areas. Purpose statement: This thesis is intended for companies that explore their possibilities to establish an assembly plant in Brazil. The aim is to try to interpret and to create an understanding concerning which factors can have an influence when relocating production activities abroad. Research method: The basis for this study has been internal information from Tetra Pak along with literature. The study has been carried out as case study based research where interviews and articles have formed the basis for the gathering of data. Results: For companies that want to establish long-term production, Brazil possesses the prerequisites required. However, not all areas in Brazil are adequate for establishing an assembly plant – industries are mainly concentrated to the federal states of São Paulo and Rio de Janeiro and these are therefore the areas best suited for production activities.

This thesis involved Tetra Pak and corrugated cardboard suppliers in China at various locations to understand how this industry looks like, the reasons for inconsistent quality and analysis of the current state of whole industry, and recommendations for improvement. As innovation can bring competitive advantage to companies, our thesis focused upon making extended value of material flow from Tetra Pak and suppliers. The aim of this project is to investigate how strategic intelligence can create value and strengthen Tetra Pak business relationship with its customers in big emerging markets like China. Theoretical framework creates a foundation for how to structure the efficiently utilize intelligence in the decision-making process for a MNC. Another aspect of the thesis was to examine supply network management process and the supplier relationship development in China, as well as the strategic, social, macro economy aspects that influence change management in medium and large organizations. Corrugated cardboard industry in China is still in a transitioning to a mature market. One conclusion drawn from the trip to China is that the dairy producer should start emphasizing visual control on quality, and less concern on price. They should see their suppliers as long term partners but not just treat them as providers. Because it is fundamentally undercutting the ability of the organization to improve what it provides to customers through better quality and productivity. It hinders efforts from reducing cost. Finally, the research problems we focus throughout this thesis will be answered after the analysis. Moreover, we will provide some suggestions about corrugated industry and our case company-Tetra Pak.

Ionic liquids (ILs) were studied as solvents for electrochemical reactions with the intent to devise metallurgical processes for Al, Mg and Ti that are less energy intensive and operate at lower temperatures than current industrial practice. Tetra-alkyl phosphonium ILs are on the low end of the IL cost spectrum and are regarded as understudied compared with imidazolium and pyridinium ILs. They are also known to be more thermally stable. The density, viscosity and conductivity of the phosphonium ILs and metal salt-IL mixtures were measured. The conductivity of the phosphonium ILs tested were found to be roughly an order of magnitude lower than imidazolium ILs; this is attributed to the relatively large cation size and localized charge. Linear density-temperature functions are presented. The viscosity and conductivity temperature relationship was modeled using the Vogel-Tamman-Fulcher (VTF) equation. The electrochemical window of A10341'14,6,6,610 was studied on a Pt substrate over a wide range of A1C13 concentrations using cyclic voltammetry (CV). It was found that the tetra-alkyl phosphonium cation is on the order of 800 mV more electrochemically stable than the 1-ethyl-3-methyl imidazolium (EMI+). Cathodic and anodic polarization of Al in A1C13-[P14,6,6,6]C1 (Xmc13 = 0.67) was studied at temperatures ranging from 347 to 423 K. The Butler-Volmer equation was fitted to the plots by varying the kinetic parameters. The cathodic reaction was found to be diffusion limited and the anodic reaction is limited by passivation at lower temperatures. The overpotential required for electrodissolution of Al was found to be higher than for electrodeposition. Aluminium was electrodeposited using both an electrowinning setup (chlorine evolution anode reaction) and electrorefining setup (Al dissolution anode reaction). The deposits were characterized in terms of morphology, current efficiency and power consumption. A variety of deposit morphologies were observed ranging from smooth, to spherical to dendritic, and in some cases, the IL was occluded in the deposit. The current efficiency and power consumption were negatively impacted by the presence of H2O and HCl present in the as-received ILs and by C12(g) generated by the anode reaction in the case of the electrowinning setup. HC1 was removed by cyclic polarization or corrosion of pure Al, resulting in current efficiencies above 90%. Aluminium was electrodeposited using the electrorefining setup with anode-cathode spacing of 2 mm at power consumption as low as 0.6 kWhr/kg-Al. This is very low compared with industrial Al electrorefining and Al electroplating using the National Bureau of Standards bath, which require 15-18 kWhr/kg-Al and 18 kWhr/kg-Al, respectively. However, due to low solution conductivity the power consumption increases significantly with increased anode-cathode spacing. Titanium tetrachloride was found to be soluble in [P14,6,6,6]Cl and increases the conductivity of the solution. Attempts to reduce the Ti(IV) included corrosion of titanium metal, corrosion of magnesium metal powder and cathodic polarization. Despite a few attempts, the electro-deposition of Ti was not observed. At this point, titanium electrodeposition from phosphonium based ILs does not appear feasible.

This study reports on an electrochemical capacitive properties of nickel tetraaminophthalocyanine (NiTAPc), nickel tetraaminophthalocyanine incorporated with Nickel oxide (NiTAPc-NiO) and nickel oxide incorporated with multi-walled carbon nanotubes (NiO-MWCNT), using three different techniques known as successive ionic layer adsorption reaction (SILAR), electrodeposition and dip-dry. This study also reports on the effect of undoped polymer of poly-pyrrole on NiTAPc. The physical properties of the synthesised materials were investigated using SEM and EDX and the electrochemical properties were investigated using cyclic voltammetry (CV), charge-discharge (CD) and electrochemical impedance spectroscopy (EIS). The supercapacitive properties of NiTAPc film on nickel foam showed a maximum specific capacitance of 416.0 Fg-1, a maximum power density of 15.50x103 WKg-1 and a maximum specific energy of 66.0 WhKg-1. The NiO-MWCNT film on nickel foam gave a maximum specific capacitance of 1034.0 Fg-1, a maximum power density of 10.41x103 WKg-1 and a maximum specific energy of 132.0 WhKg-1. The NiTAPc-NiOE film on nickel foam was found to possess a maximum specific capacitance of 1117.0 Fg-1, a maximum power density of 20.48x103 WKg-1 and a maximum specific energy of 119.0 WhKg-1. The NiTAPc-NiOE-S film on nickel foam gave a maximum specific capacitance of 1279.0 Fg-1, a maximum power density of 26.96x103 WKg-1 and a maximum specific energy of 114.0 WhKg-1. Finally, the NiO mixed with an oxidant (NiOS-ox) film on nickel foam gave a maximum specific capacitance of 1403.0 Fg-1, power density of 14.44x103 WKg-1 and a maximum specific energy of 147.0 WhKg<sdup>-1. In addition, the electrodes were found to be very stable even after repetitive cycling. These electrodes have clearly proved that they may be suitable for use as potential supercapacitors. Further research is necessary to fully explore their supercapacitive behaviour in single cell (2-electrode)systems.
