1. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure
University essay from Lunds universitet/Kemiteknik (CI)Abstract : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. READ MORE

2. MEASURING ECO-EFFICIENCY OF PRODUCTION IN OECD MEMBER COUNTRIES : A STOCHASTIC FRONTIER ANALYSIS
University essay from Umeå universitet/NationalekonomiAbstract : This paper analyzed the eco-efficiency of 27 OECD member countries by using output-oriented Stochastic Frontier Analysis (SFA) model. In the set-up of the model, Gross Domestic Product (GDP) was used as a good output whereas Carbon dioxide (CO2), Sulphur dioxide (SO2) and Nitrogen oxide (NOx) emissions were used as bad outputs.

3. Temperature Dependent Electrical Characterisation of Vertical InAs-InGaAs Nanowire MOSFETs
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : This thesis presents the temperature dependence of InGaAs Nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs) grown at two different temperatures. The two different growths represent one sample having nanowires which have a mixed crystal structure (showing stacking faults) and one sample with nanowires of pure crystal structure (without stacking faults).

4. Photocatalytic activity of titanium dioxide thin films deposited with high power impulse magnetron sputtering
University essay from Uppsala universitet/Fasta tillståndets elektronikAbstract : High power impulse magnetron sputtering has shown a lot of promise as a way of depositing photocatalytic thin films of titanium dioxide at low temperatures, however, the films deposited are often amorphous and display uncertain photocatalytic abilities. This thesis explores the deposition and characterization of photocatalytic thin films deposited with high power impulse magnetron sputtering. READ MORE

5. Recycling of Textile and Plastic from an Interior Vehicle Component
University essay from KTH/Fiber- och polymerteknologiAbstract : På grund av den rådande klimatförändringen och de globala problem som plast orsakar i miljön blir det allt viktigare att dagens linjära materialanvändning ändras till en cirkulär användning. Inom fordonsindustrin har kravet på ökad tillgänglighet och kvalitet på återvunna material identifierats. READ MORE
