▼ Ship recycling has been considered as the best means to dispose off an obsolete ship. The current state of art of technology combined with the demands of sustainable developments from the global maritime industrial sector has modified the status of erstwhile ‘ship breaking’ involving ship scrap business to a modern industry undertaking dismantling of ships and recycling/reusing the dismantled products in a supply chain of pre owned product market by following the principles of recycling. Industries will have to formulate a set of best practices and blend them with the engineering activities for producing better quality products, improving the productivity and for achieving improved performances related to sustainable development. Improved performance by industries in a sustainable development perspective is accomplished only by implementing the 4E principles, ie.,. ecofriendliness, engineering efficiency, energy conservation and ergonomics in their core operations. The present study has done a comprehensive investigation into various ship recycling operations for formulating a set of best practices.Being the ultimate life cycle stage of a ship, ship recycling activities incorporate certain commercial procedures well in advance to facilitate the objectives of dismantling and recycling/reusing of various parts of the vessel. Thorough knowledge regarding these background procedures in ship recycling is essential for examining and understanding the industrial business operations associated with it. As a first step, the practices followed in merchant shipping operations regarding the decision on decommissioning have been and made available in the thesis. Brief description about the positioning methods and important preparations for the most feasible ship recycling method ie.,. beach method have been provided as a part of the outline of the background information. Available sources of guidelines, codes and rules & regulations for ship recycling have been compiled and included in the discussion.Very brief summary of practices in major ship recycling destinations has been prepared and listed for providing an overview of the global ship recycling activities. The present status of ship recycling by treating it as a full fledged engineering industry has been brought out to establish the need for looking into the development of the best practices. Major engineering attributes of ship as a unique engineering product and the significant influencing factors on her life cycle stage operations have been studied and added to the information base on ship recycling. Role of ship recycling industry as an important player in global sustainable development efforts has been reviewed by analysing the benefits of ship recycling. A brief synopsis on the state of art of ship recycling in major international ship recycling centres has also been incorporated in the backdrop knowledgebase generation on ship recycling processes.Publications available in this field have been reviewed and classified into five subject categories viz., Infrastructure…

▼ ENGLISH ABSTRACT: In this study, the possibility of titanium recycling in South Africa is explored. Inspired by recent beneficiation processes for the production of titanium from South Africa's vast mineral resources, this study identified the opportunity to create sustainable value from the inevitable influx of scrap, once these beneficiation strategies have been implemented. The objectives were to research all methods capable of recycling titanium, map their process chains, and model them financially. Furthermore, a feasibility framework was to be created, which serves the purpose of showing when each recycling method becomes financially feasible. Finally, a business case was to be created after choosing the best recycling alternative in South Africa at the time of the study. A background study was done at Hansens Engineering in Port Elizabeth, to gain insight into a state-of-the-art waste-to-resource process through their in-house aluminium recycling operations. Eight methods of recycling titanium are identified in the literature review, namely washing and briquetting swarf, precision casting, thermal degreasing, ferrotitanium production, vacuum-arc remelting (VAR), electron beam cold hearth melting (EB CHM), plasma arc cold hearth melting (PA CHM) and mill product production. Each process is modelled financially, by use of a factorial method, which utilises equipment, operating labour, waste treatment, utilities and raw material costs as input variables to estimate total fixed capital investment and total manufacturing costs. A ten-year NPV analysis on each process is done, which is used to conduct the feasibility study, which consists of break-even analysis, scenario analysis, and the creation of the feasibility framework. The break-even analysis determines the yearly volume of scrap required to make each recycling method financially feasible. By use of this, the feasibility framework is created. The break-even volumes are contextualised by use of benchmark components. This is used to represent the break-even points of each recycling method in terms of an amount of components, as opposed to a volume of titanium scrap. The financial feasibility models are also used to perform scenario analysis using pessimistic and optimistic hypothetical swarf availabilities, based on South African titanium trade statistics. Based on the collective feasibility study results, it is found that only two of the eight recycling processes are financially feasible at present, namely washing and briquetting swarf, and precision casting. The best option for recycling titanium at present is identified as precision casting, which shows a positive NPV of R650.55 million and R81.96 million in the optimistic and pessimistic hypothetical scrap availabilities, respectively. Uncertainty analysis is performed on this process through the use of Monte-Carlo simulation. Input variables are varied over probable ranges, or by fitting distributions on historical data, to predict the probability of having a positive NPV… Advisors/Committee Members: Oosthuizen, Gert Adriaan, Bam, Wouter, Stellenbosch University.

▼ Diversion rates of solid waste due to recycling and other efforts vary across communities for multiple reasons. Past research has provided demographic and attitudinal profiles of recyclers and non-recyclers at mainly the individual and household levels with some at the community level. Researchers have found both commonalities and variations in these profiles. Studies have also looked at how the structure of a recycling program influences recycling behavior. The question asked here is how community-level demographic and attitudinal characteristics interact with the structure of public recycling programs to influence aggregate rates of recycling participation and diversion in 40 cities in the western United States. The results of this study provide modest support for my hypotheses that when recycling programs are less convenient, demographics and attitudinal characteristics will explain more variation in diversion of waste at the community scale. Similarly, as recycling programs become more convenient, the roles of demographic and attitudinal factors (recycling friendliness) are expected to decrease. This study found increased recycling program convenience and less visible fee assessment structures were associated with higher rates of recycling among cities regardless of their degree of recycling friendliness. When recycling outcomes were cross tabulated with indicators convenience and fee assessment, low rates were generally found among cities with low program convenience and high rates were generally found among cities with high program convenience. Cities with less convenient programs were more likely to see higher rates of recycling when their underlying demographic and attitudinal attributes reflected characteristics that have been associated with increased recycling activity. However, when program convenience was high (and fee structures less visible) high rates of recycling were found across cities with both favorable and unfavorable demographic characteristics. I use case-specific detailed narratives to explore the factors that influence outcomes among selected cities that did or did not meet my expectations.

▼ Reverse osmosis concentrate (ROC) is considered to be an obstacle in the production of high quality water from water reclamation and desalination plants using dense membrane systems. It normally comprises 10-30% of the feed water of water reclamation plants and 50-75% of the feed water from sea water desalination plants. While coastal water reclamation plants have the opportunity to discharge the RO concentrate directly into the ocean, inland facilities depend on controversial options such as surface water discharge, evaporation ponds, deep well injection and land applications. However, all these options are not sustainable or environmentally friendly. Therefore methods for proper disposal of RO concentrate especially for inland plants are urgently required. Various integrated concentrate treatment concepts have been proposed to minimise waste and maximise water recovery. A key issue in applying the Zero Liquid Discharge principle is the impact of foulants on the concentrate desalinating system, consisting of forward osmosis (FO) and a subsequent crystalliser. This study investigates forward osmosis, which appears to be a promising technology that represents a step towards zero liquid discharge. Organic fouling and inorganic scaling are hypothesised to be the main membrane foulants in FO. Furthermore FO is analysed in the context of removing organic micropollutants from RO concentrate. The following methodology was applied to this study. Two types of flat sheet membranes Cellulose Tricacetate (CTA) and Thin-Film Composite polyamide (TFC-PA) supplied by Hydration Technology Innovation for FO were used. Two model foulants - alginate and humic acid - were used to examine organic fouling of FO membrane. Real RO concentrate from the Sydney Olympic Park Authority’s water recycling plant was used to study fouling and its impact on water flux. Both membranes showed similar trends but permeate flux was higher with the TFC-PA membrane compared to the CTA-NW membrane. Forward osmosis was studied in two ways: FO mode (active layer facing feed solution); and pressure retarded mode (PRO) modes (support layer facing feed solution). The results indicate that alginate is a strong foulant of the PA membrane in PRO mode, and the resulting flux decreased sharply. On the other hand, however, in FO mode only moderate fouling was observed. CTA and TFC (PA) membranes were checked for fouling by humic acid. Approximately 7% TOC was adsorbed on the membrane’s surface resulting in a minor flux decline of 2-4%. Real RO concentrate was tested in concentrations of 38 mg/L (TOC equivalent) with both membranes in FO mode. The TOC adsorption at the membrane surface was low between 2-9%, however a high flux decline was observed with increasing draw solution concentrations. The observed flux decline was about 10-26% for the CTA membrane and 5-55% for the TFC-PA membrane, depending on the DS concentration of 1-4 M NaCl in both cases. Analysis of the inorganics revealed that inorganic scalants were the major contributor to the flux decline.…

▼ The rate of waste electrical and electronic equipment (WEEE) is growing at an alarming rate, especially in countries where markets are saturated with huge quantities of new electronic goods. Printed circuit boards (PCBs) are a substantial portion of the value contained in waste from WEEE although they are only 6% of the total weight. It is reported that WEEE is currently the fastest growing waste stream in South Africa as the general population’s access to electronic goods in the last decade has increased, especially access to mobile phones. PCBs are found in any piece of electrical or electronic equipment and consist of various metals including precious metals such as gold (Au), silver (Ag) and palladium (Pd). It is reported that gold has the highest economic incentive at 15,200 $ per ton of PCBs. The rapid introduction of new and advanced technology into mobile phones has caused mobile phones to have a relatively short life span, 1 to 2 years to be exact. Mobile phones printed circuit boards (MPPCBs) have more Au content compared to computer circuit boards. They contain 350 g/ton Au whereas computer (PC) PCBs contains 250 g/ton. This research project will recover gold from waste mobile phones PCBs pregnant ammonia thiosulphate leach solution using copper cementation. The cementation process is preferred to all the other technologies of metals extraction from solution due to ultrahigh purity metals that can be obtained and to the less consumption of materials and energy. Electronic parts on the PCBs were manually removed using pliers and screwdrivers. PCBs were then cut to smaller pieces of about 2 x 2 m. The pieces were crushed and milled respectively. Some of the particles were recycled back to the crusher to get finer particles. The particles were separated to particles of sizes between 0 and 1350 μm using a shaker. The comminuted fractions of the PCBs were then used in the leaching step. Batch cementation experiments were performed by bubbling N2 in glass reaction vessel with a working volume of 0.5 L. The reactor was connected to a circulating water bath for temperature control. The recovery percentage of gold at various temperatures, agitation speeds and different amounts of copper powder used, was determined while pH was monitored. The temperature was varied at 30 °C, 40 °C, and 50 °C and the agitation speeds at 300 RPM and 900 RPM. Copper powder was added at 0.5 g/L, 1 g/L, and 1.5 g/L. Gold concentrations were measured by atomic adsorption spectrophotometer (AAS). Scanning electron microscope (SEM) and Energy-dispersive x-ray spectrometry (EDS) analyses of the copper powder after cementation (precipitates) were used to determine the surface morphology and to evaluate the quantitative aspect of the precipitate. It was found that the recovery of gold from ammonia thiosulphate leach solution was greatly affected by agitation speed. At an agitation speed of 900 rpm, 40 °C and 0.5 g of Copper powder, 96% of the gold was recovered from the leach solution. The cementation rate increased as temperature was elevated… Advisors/Committee Members: Aziz, M (advisor), Ojumu, T.V., Prof (advisor).

▼ Geopolymers and alkali activated materials are deemed as the sustainable alternative to Portland cement-based binders. Despite extensive reference on the cradle-to-gate environmental benefits, end-of-life impact of geopolymers remains largely overlooked. The present thesis aims to address this by investigating the recyclability of fly ash-slag based geopolymer concretes as aggregates in Portland cement mixes. The relationship of matrix composition and recyclability was investigated by fabrication and testing of geopolymers to be recycled (Source Concretes), chemical and physical properties of crushed geopolymers (Recycled Aggregates-RA) and their effect on Portland cement mixes (Fresh properties and cement hydration, Mechanical Properties &Microstructure, Durability & Long-term Properties). The Source Concretes comprised 3 fly ash-slag geopolymers with varying percentages of sodium and silica (S-Standard, HA-High Alkali, HS-High Silica) and one Portland cement mix (PC). Porosity of RA was mainly affected by crushing and the distinct carbonation mechanism of geopolymers, but not by mechanical and physical properties of Source Concretes. Ion Exchange Chromatography indicated leaching of Na⁺ above 150mg/l and K⁺, SO₄⁻³ and Ca⁺² below 100mg/l after 24 hours, depending on RA type. Two series of concretes, slump categories S1 and S3, with 20% recycled aggregates were fabricated. Aggregate replacement by volume was found to provide more consistent mixes. The kinetics of cement hydration were not altered, but according to Vicat needle test presence of Na⁺ and Ca⁺² on leachate delayed setting by 2-3 hours. Overall the strength reductions exhibited from S3 concretes were within expected limits. Concretes with HA and PC RA exhibited similar strength development across series by having significantly low early strength. It appeared that leached elements Na, K and S were uniformly incorporated in the hydrated paste and SEM imaging revealed variety of C-S-H morphologies and hydrates at 7 days. No clear correlation between an RA type and specific hydrates or a distinct effect on strength was found though. The evidence strongly suggested that ITZ between the old geopolymer and the new Portland cement paste was the governing factor for concrete strength. No element migration took place at later stages through the ITZ. Porosity of concretes was not affected by RA. Concrete with 20% crushed HA geopolymer and glass aggregate did not show signs of alkali silica reaction after 15 months, when evaluated against a positive control mix and the concrete prism method threshold. The findings of this thesis demonstrated recyclability of fly ash-slag based geopolymer concrete. The effects of recycled crushed geopolymers were comparable to those of Portland cement recycled aggregates. Further research on long term aspects and field testing is required.

▼ Companies are no longer judged on financial performance alone, but rather on their Triple-Bottom Line, which accounts for social and environmental measures as well. This leads companies to investigate the sustainability of their operations and their products. Between the increasing cost of virgin raw materials and customers demanding post-consumer product content, manufacturers have begun looking at recycled material options. This paper addresses a procurement issue facing a polystyrene packaging manufacturer considering its optimal purchasing strategies between two suppliers one providing virgin material, the other offering recycled material. A single-period scenario is modeled where each supplier sells product with a known yield distribution at market pricing. The manufacturer must choose whether to sole-source or dual-source, as well as determine how much material to purchase from each supplier to meet deterministic demand. Our results indicate that there is a range of prices from the recycled material supplier where dual-sourcing will lead to higher manufacturer profits compared to sole-sourcing. We show, based on the procurement strategy, the optimal quantities to purchase to maximize manufacturers expected profit. We then investigate the area of supplier development and how the manufacturer can improve their expected profit by investing in their suppliers quality improvement effort. The questions addressed are how much the manufacturer would be willing to invest and how they ensure the proper return on their investment. This paper determines the expected increase in profit for the manufacturer from yield improvement projects at a supplier, which therefore becomes the upper threshold for investment. We also find that a company can err in their project acceptance criteria if they have an approval process that views project acceptance myopically rather than holistically. Lastly, we develop a systematic and comprehensive approach to the supplier selection process. We utilize the fundamental concepts behind W. Edwards Demings Plan-Do-Study-Act improvement cycle and apply them to the supplier selection process. We also present analytic and numerical study results that can be used in conjunction with contractual mechanisms to not only overcome issues such as free riding, but to also incentivize suppliers to engage in supplier development projects they may not have otherwise undertaken.

▼ This project investigated the potential for the regeneration of fibres from cotton-based waste garments. The project focused on the preparation of the cotton waste pulps and assessed the suitability of the prepared material for regeneration of ReCell fibres. Mechanical processes have been developed to degrade the fabrics into a fibrous pulp potentially allowing easier fibre dissolution and purification in the fibre regeneration processes. Wet degradation and dry degradation methods were evaluated and the optimal method identified. It was established that the wet deconstruction method could produce fibres with longer length and lesser degradation of the cellulose than the dry deconstruction method. The pulp produced by wet deconstruction methods could be formed into sheets which were stronger than the pulp produced by the dry deconstruction methods. Although the cotton pulp reclaimed by the wet deconstruction methods requires extra energy to dry, it is still the most attractive processing route since the pulp will be transported to the fibre spinning plant in the form of dry cellulosic sheets.Methods for stripping off the easy care finishes in order to increase dissolution of the cellulosic garments were optimised. The stripping performance was assessed by fibre degradation, contents of the easy care finishes, and solubility of the stripped fibres in selected solvents. It was established that a combination of acidic and alkaline treatment can effect the removal of all easy care finishes and enable efficient dissolution of the pulps for fibre making. ReCell fibres were produced from 100% reclaimed material and a blend of reclaimed cotton pulp and wood pulp and structural and mechanical properties were characterised and compared to the existing Lyocell fibres. It was established that for easy separation of non-cellulosic material from the cellulose-based waste garment pulp the fibres must be modified to avoid formation of tufts. Fibre enrichment by gravity separation was recommended as a pre-requisite process prior to wet cyclone separation and the optimisation of the process was recommended for future work. ReCell processing of dyed waste garments, fibre spinning, fabric construction and wet processing of ReCell fibres have been recommended for future work. The results from this project will be used for pilot tests and later commercial production of ReCell fibres by Lenzing Company. Commercial production of ReCell fibres will contribute to the reduction of economic and environmental challenges caused by textile wastes. Moreover, the findings have identified a potential reduction of pressure on raw material for fibre production by providing an alternative source of material for regeneration of cellulosic fibres.

▼ Composite materials are widely used in various sectors such as aerospace, automotive and wind energy. Global increase of demand, particularly for fibre reinforced plastic (FRP) composites, unavoidably lead to high volumes of manufacturing and end of life waste. Currently, the most common disposal route for composite waste is through landfill. However, current and impending legislations such as Directive on Landfill of Waste (1999/31/EC) and End of Life Vehicle (ELV) Directive (2000/53/EC), have limited the amount of composite waste permitted for landfilling. In addition, production of virgin composite materials requires higher energy input in comparison to other counterpart materials such as steel and aluminium. This calls for an urgent need for composite waste to be recycled and reused in close loop and cross sector applications. The composite materials have a heterogeneous nature. Thermoset matrixes, which are used in most high grade applications, have three dimensional cross-linked structures which make melting and remoulding impossible. Such complex nature requires appropriate composite recycling technologies, a number of which are currently under research and development. At this early stage it is important to select and develop sustainable solutions in terms of economic performance and reduced environmental impact. Unfortunately at present, there is limited high integrity environmental related data in literature to help assess the life cycle benefits of composite recycling. This information is vital in exploring environmental credentials of composite recycling processes, and to ensure resource efficient use of manufacturing and end of life composite waste. The work reported in this PhD thesis deals with the investigation of energy demand of composite recycling processes. Composite waste and demand in the UK market was captured through Sankey diagrams. The diagrams, combined with environmental footprints of virgin material and recycling processes, were used to identify resource benefits of composite recycling initiatives. Furthermore, environmental data for mechanical recycling of glass fibre composites was derived through new and novel bottom up process science inspired mathematical energy modelling approaches. It was found that the process specific energy demand is dependent on the processing rate. The effects of key process variables in mechanical recycling on process energy demand and recyclate quality were also investigated. This study highlights the importance of selecting the right conditions for running recycling processes and generating recyclate with a high market value. Potential of new recycling techniques, namely high voltage fragmentation, was also assessed. Performance of the method, which was originally developed for fracturing rocks, was compared to the mature mechanical recycling process. The final part of this study used a life cycle assessment method to evaluate end of life options for an automotive composite product with the highlights on positive environmental impacts of recycling… Advisors/Committee Members: Mativenga, Paul.

▼ This dissertation describes the use of lipophilic molecules as solubility promoters for the development of homogeneous recyclable catalysts, the facilitation of efficient purification in organic synthesis, and the preparation of highly soluble nanoparticles in nonpolar solvents. Several polyisobutylene (PIB)-bound were used as catalysts. PIB-bound cobalt(II) MPc was synthesized and used as an effective and recyclable catalyst for nitroarene reduction. The result showed that the catalyst was effective and recyclable for at least 10 cycles. The use of a PIB-bound iron(II) MPc for aerobic oxidation of ethyl phenylhydrazinecarboxylate and the use of a PIB-bound chromium(III) MPc for the rearrangement reaction of an epoxide to an aldehyde are also discussed. Octadecyldimethylchlorosilane was used as a silylation reagent and a purification auxiliary. A procedure using heptane phase selectively soluble octadecyldimethylsilyl groups to facilitate separations and silyl reagent regeneration was developed. Alcohols and alkynes protected by these groups were shown to be phase-selectively soluble in hydrocarbon solvents, allowing these compounds to be purified by a simple liquid/liquid extraction. Applications of using the octadecylsilyl protecting group in a Grignard synthesis and Sonogashira reaction were studied. Highly heptane-soluble iron-oxide nanoparticles were synthesized using PIB-supported ligands. These PIB-supported ligands were synthesized and grafted to nanoparticles to prepare heptane-soluble PIB-modified magnetic nanoparticles as magnetically susceptible oils. These magnetic oils were dissolved in poly(alpha-olefin)s and molten polyethylene to prepare magnetically susceptible polymeric nanocomposites. Using the magnetic oil to remove heptane from water is also discussed. The work was also extended to explore strategies that can solubilize silica nanoparticles in heptane.

▼ This study sought to establish factors influencing recycling of solid waste in urban areas within Machakos County. The aims of the study were; to ascertain how technical factors influence recycling of solid waste in Machakos County, to determine how financial factors can affect recycling of solid waste in the Machakos County, examine the influence of stakeholder involvement on solid waste recycling in Machakos County. The target population for this study was Machakos county‟s employees in the solid waste management department, NEMA officials, public health officials and MOH. The study employed a descriptive survey design and interview guide to key informants and the target population was 122 individuals drawn from different sub-counties in Machakos County. A stratified sampling technique was used. It comprised of all the respondents who were targeted. There was collection of primary data using questionnaires. Analysis of the data collected from the pilot study done was analyzed using SPSS 21 and Microsoft Excel. The study found that financial factors played a role influencing recycling of solid waste in Machakos County. Technical factors such as lack of professional personnel and equipment had an association to recycling solid waste. Stakeholder involvement such as informal sector, community based organizations, donors and NGO‟s have an influence on recycling of solid waste. The researcher examined the data and demonstrated the results in tables. The recommendations in this research centered on factors influencing recycling of solid waste in Machakos County, Kenya were, strict enforcement of by-laws and policy, more budget allocation and proper waste allocation systems which are as follows: The County government should allocate enough budgets for provision of SWM services within the county. The county should facilitate proper waste management activities so as to reduce, reuse and recycle solid waste in the county‟s environment. Additionally, the County should advocate for good recycling activities of the solid wastes to add value by converting the solid wastes to useful products. Besides, it should develop market for the solid waste materials by putting in place good policies for disposing the materials. The county should enforce regulations while at the same time promoting campaigns which will reduce disposal of solid waste in the county. It will be important to publicize training manuals, best practices and also provide useful technical and financial assistance which will encourage better solid waste recycling and reusing practices.
