Abstract:

Biological wastewater treatment is typically aerobic and an energy intensive process, mainly due to the required aeration. Alternative sustainable processes are sought, such as Microbial fuel cells (MFC) where electrogenic bacteria can degrade organic matter present in the waste stream while simultaneously generating electricity. MFCs represent an emerging technology which may deliver the capability to reduce the pollution potential of low strength wastewaters (< 1500 mg COD l-1) while generating electricity which could be used to self-power the process. Waste streams high in volatile fatty ac

Stabilization and electrical contacting of redox enzymes with electrodes are fundamental requirements for the development of bioelectronics devices such as biosensors and EFCs. In the present work, we show that glucose oxidase (GOx) stability could be increased by immobilization with Nafion. The immobilization process affected GOx conformation but was not detrimental to its activity, which was maintained for over 120 days. The GOx/Nafion system was interfaced to a carbon cloth electrode and assembled in a prototype EFC fed with glucose. Polarization and power density curves demonstrated that G

This thesis examined the economics of producing high value bio-ingredients such as chitin and carotenoprotein from shrimp processing waste in Newfoundland. The shrimp waste in the province was estimated to be at least 37000 tons annually.

The economic engineering approach was employed to estimate the production cost of chitin and carotenoprotein at the laboratory and pilot scale levels.

Abstract:

This thesis reports the properties of bio-oil-based fuel mixtures. For bioslurry fuels, the interaction between biochar and bio-oil results in changes in fuel properties and the redistribution of inorganic species. For glycerol/methanol/bio-oil (GMB) fuel blends, the solubility and fuel properties are improved upon methanol addition but other impurities in crude glycerol worsen the solubility with limited impact on properties. It is also possible to integrate the GMB blends production into the biodiesel production process.

Abstract:

The aviation industry is growing rapidly and the carbon dioxide emissions from the industry are following in the same manner. Biofuels made from edible feedstock have had an impact on lowering the emissions but at the same time an impact on increasing food prices. There are a few alternative fuels on the market today (TF-SPK, HEFA-SPK) which work in a blend with the petroleum based fuels, reducing the emissions from the aircrafts. Biofuels from next generation biomass, also called advanced biomass, such as algae and lignin, seem likely to be a good substitute for the first generation biofuels.

Crude glycerol (CG) improves the ignition and cold flow behavior of slurry fuels while has limited effect on fuel properties.

Biomass is one of the renewable energy resources that has carbon in its building blocks that can be processed into liquid fuel. Napier grass biomass is a herbaceous lignocellulosic material with potentials of high biomass yield. Utilization of Napier grass for bio-oil production via pyrolysis is very limited. Bio-oil generally has poor physicochemical properties such as low pH value, high water content, poor chemical and thermal stabilities which makes it unsuitable for direct use as fuel and therefore requires further processing.

Abstract:

Uno de los retos actuales de la ciencia y la tecnología es el desarrollo y utilización de fuentes de energías limpias, sostenibles y seguras, con el fin de sustituir el uso de combustibles fósiles. La energía solar, única alternativa viable, puede convertirse y almacenarse en forma de enlaces moleculares, mimetizando el proceso de fotosíntesis de las plantas, para la obtención de combustibles u otros productos de valor añadido. Para ello se requieren materiales semiconductores que puedan absorber y transformar la energía solar en energía química de manera eficiente. En la presente tesis doctor

Abstract:

Increasing plastic consumption has created an alerting problem with waste disposal of the mixed waste plastics once the recyclable fractions have been recovered. The percentage sent to landfill of the generated mixed plastic waste amounts to one third of the total. Liquid fuel recovery from mixed plastic waste is possible using pyrolysis as a tertiary recycling process. The focus of this study was to obtain useful liquid product recovered from the pyrolysis of a variety of commercial mixed plastic waste utilising a pilot scale fluidised bed reactor of 1kg/hr processing capacity. The influence

Abstract:

An innovative current collection architecture for micro-tubular solid oxide fuel cells (SOFC) has been developed. A nickel wire is coiled around a thin carbon composite rod in order to fabricate cell supports. Different carbon composites such as pencil leads and carbon fibres were investigated. The cell support was then coated with ceramic slurries based NiO/YSZ and YSZ for anode and electrolyte, respectively, by successive dip coatings. Effect of thermal behaviour, porosity, amount of binder and dip coating parameters were conjunctly analysed to produce anode and electrolyte crack-free layer
