Abstract:
As the plastic industry continues to grow globally, with plastic materials contained in a vast quantity of consumer products, the management of the resultant waste has become one of the greatest challenges of our time. Greater than 8 million metric tons of plastics were estimated to enter the world’s oceans as of 2010, with an even larger amount remaining on land. The associated ecological and health effects of plastic waste disposal are many, and existing solutions can only tackle small portions of the waste.China and Indonesia top the current list of contributors to ocean contamination with

In the first part, the current industrial plant was presented with all necessary process data. Furthermore, all the key equipment used for the waste gases treatment or for the utilization of waste heat was identified. In the mai

Abstract:
High temperature corrosion of the heat exchanger materials is the important factor that limits the efficiency of various energy systems. The problem becomes more serious when fuels containing alkali metal, heavy metals, chlorine, and sulphur are used. In combustion systems utilizing biomass and municipal solid waste, the steam temperatures are kept lower than 450"C in order to avoid the corrosion problems. This results in low overall plant efficiencies (e.g. 25 - 30%). Therefore, methods to prevent or control high temperature corrosion in these plants must be investigated.

Abstract:
Swine production represents approximately 40% of the world's meat production, and swine wastes contain high concentrations of organic matter, nitrogen (N) and phosphorus (P). Swine production is intensifying as meat demand increases and concentrated animal feeding operations (CAFOs) are becoming increasingly common, making it difficult to treat the waste generated. A system for holistic treatment of swine waste produced in CAFOs was investigated in this study that sustainably generates energy and recovers N and P as saleable fertilizers. The system uses anaerobic digestion (AD) for methane pro

In order to answer modern challenges, which come from increasing needs in energy forprivate persons and industries as well as in order to decrease negative environmentalimpacts, caused by the processes of energy generation, it is important to constantly searchfor untapped energy efficiency potential. Moreover, nowadays, energy efficiency hasbecome one of the prerequisites of successful market competitiveness for any type ofindustry on local and global levels.An energy audit is an instrument, which can be used for understanding how the energy isused and identify possible energy-saving opportuni

Abstract:
High grade energy, which is primarily derived from hydrocarbon fuels, is in short supply; therefore alternative energy sources such as renewable and recycled energy sources are gaining significant attention. Pyro-metallurgical processes are large consumers of energy. They in return generate large quantities of waste heat which goes un-recovered. The overall theme of this research is to capture, concentrate and convert some of this waste heat to a valuable form. The main objective is to characterize and develop heat pipe technology (some of which originated at McGill) to capture and concentrate

Abstract:
This research project aims to explore the hypothesis that a Community Technology approach can be considered appropriate for reclamation and recycling activities, and to investigate the opportunities for reclaiming and recycling domestic wastes viably at a 'community' scale. A framework is first established to define a Community Technology approach, and then used to assess the compatibility of reclamation and recycling technologies to this approach. 'Community '-scale reclamation and recycling in Britain, together with some examples from the USA, is examined and the 'state of the art' for both

Abstract:
<p>The energy system in Uganda is largely based on biomass and especially wood. The high demand for wood results in fast reductions of the available wood stocks. This thesis is focusing on biomass waste as a supplement to the existing energy carriers. This thesis includes agricultural residues from the main cash and food crops in Uganda, as well as municipal solid waste (MSW) in Kampala. The available biomass waste resources are mapped, the energy content is examined and possible ways of utilization is discussed by using material flow analysis, MFA. The MFA flow schemes are provided for all th

Abstract:
Considerable work has been done on the mechanical properties of coconut-fibre enhanced concrete. The primary test variables were the fibres weight fraction, and fibres aspect ratio. The addition of coconut-fibres significantly improved many of the engineering properties of concrete, notably torsion, toughness and tensile strength. The ability to resist cracking and spalling were also enhanced. However, the addition of fibres did not improve the compressive strength, as expected, due to difficulties in compaction which consequently lead in increase of voids. When coconut fibre was added to plai
