Abstract:
The study was conducted to explore the current status and the economical prospect of the solid waste management at Amin Bazar waste dumping site, Dhaka. A total of 48 waste samples were collected in both dry and wet season to study the physical composition, pH and moisture content of discarded wastes. The wastes were comprised of plastics (6%), paper (3.5%), glass (0.23%), garden waste (8.5%), food stuffs (72.25%), metals (0.16%) and textile products (3.25%). The pH values of the samples were ranges between 6.9-7.8 indicated the neutral condition. Larger portion of the wastes was organic (72%). About 14.38% of waste was recyclable but there is no recycling and composting facility. Proper recycling of the solid wastes at Amin Bazar can be a source of compost and useful metal resources which may contribute in safe and sustainable environmental management.

Abstract:
The article presents an alternative method of recycling of dispersed metal waste, based on a continuous solid-liquid-phase process, implemented in rotary tilting furnaces (RTF). The new proposed method of recycling allows processing wastes with almost any composition and state from metal to oxide and multicomponent wastes (shavings, fine scrap, mill scale, aspiration dust, sludge, etc.). The wastes can be even contaminated with moisture, oil, and organic impurities. The method developed does not require preliminary preparation of the initial materials (cleaning, homogenization, pelletizing, etc.). The finished products are ingots (pigs) for subsequent processing aiming the particular chemical composition or cast alloys of certain brend.

Abstract:
Owing to rising population and increasing energy demand, renewable energy resources become the most convenient and promising solution. Hence, solar power plant investments and photovoltaic module numbers have risen sharply. Turkey is one of the tight followers of the energy trends, thanks to its rising energy demand and economic power. However, the consequences of the massive plant wastes importance in term of economically and environmentally have not been understood yet. Almost 70% of the modules are formed by glass and the rest accumulates economically valuable metal materials, which are silver, aluminium and copper. These three main materials are substantially important in the overall waste. Not only the economic value, but also the environmental impacts of the mining effluents to excavate these metals are causing emission problems. As a chain reaction, the higher energy demand triggers a search for new and renewable energy resources. This is why popularity of solar energy has increased. Solar energy can be absorbed and transformed through photovoltaic modules, which contain glass and three main metals. In order to respond for the production of modules, metals are fundamental. This need triggers the need of metals mining excavations and emissions. In this respect, in the near future, thanks to the rising investments on photovoltaic modules and the CO2 emissions coming from mining, the wastes of photovoltaic modules and the need of recycling will become more important. That is why, in this study it is aimed to present environmental benefits and economic recoveries of recycling photovoltaic module in Turkey.

Abstract:
Waste water from the mining industry is generally extremely complex and contains numerous species which influence the adsorption of the metals to any biomass. A variety of factors need to be addressed before treatment is considered viable. It is also beneficial to establish the binding characteristics of the metal of interest to maximise its interaction with the biomass to be utilised. Azalia filiculaides was investigated in the adsorption of gold(III), lead(II), iron(ID), copper(II) and platinum (IV). In batch studies, the optimum biomass and initial gold(III) concentrations were found to be 5 gIL and 8 mgIL respectively. The adsorption of gold(ID) is principally pH-dependent with optimal removal at pH 2. Lead(II), iron(III) and copper(II) did not compete with gold(III) adsorption under equimolar and simulated effluent conditions. Halides, with increasing affinity for gold (chloride < bromide < iodide), can affect gold uptake with the soft base, iodide, exhibiting the most inhibition (25%) and the hard base, chloride, O%. Mercaptoethanol (soft base) showed no interference in gold(III) adsorption while the presence of sulphate (hard base) and sulphite (borderline base) showed that concentrations in excess of 1 0 mM may adversely affect gold(ill) uptake, most likely due to competition for cationic sites on the biomass. Column studies, better suited to high volume treatment, indicated that a flow-rate of 5 mL/min and an initial gold(ill) concentration of 5 mgIL was optimal. Competitive effects between lead, iron, copper and gold again showed little or no interference. The halides, chloride, bromide and iodide, affect gold(ill) uptake similarly to the batch studies, while the bases mercaptoethanol and sulphate minimally affect gold(III) binding with sulphite severely hampering adsorption (70% inhibition). To optimise gold desorption, preliminary batch studies indicated that a ratio of 1:1 of adsorbentdesorbent was optimal, whilst gas purging of thiourea with oxygen, air and nitrogen decreased gold elution in proportion to decreased amounts of oxygen. A series of desorbents were utilised, in column studies, to optimise and determine the speciation of bound gold. The presence of an oxidant with thiourea enhanced desorption greater than 3 fold when compared with thiourea alone. Thiourea desorption studies, aided by the oxidant, suggest that gold is present in the + I and 0 oxidation states. Ultimately thiourea, perchloric acid and hydrochloric acid was found to be the most optimal elutant for gold (J 00% recovery). For selective metal recovery oflead and copper, pre-washing the plant material with water, utilising an acid (0.3 M nitric acid), pumping in an up-flow mode, and recycling the desorbent six times was found to be optimal elutant for gold (J 00% recovery). Cost analysis of utilising elutant versus incinerating the biomass for gold recovery indicated the latter as the most economical. Over a 5 cycle adsorption and desorption series, acid desorption before each adsorption cycle was found to result in greater than 92% desorption for lead and 96% for copper. Gold recovery was 97% with incineration. A preliminary study with gold effluent (Mine C) indicated that nickel and sulphate was removed in batch and column studies. Gold removal was found to be 100% and 4% in batch and column studies respectively. Adsorption of gold in the effluent study was accompanied by the release ofHt. Modifying the plant material with various reagents failed to identify the primary binding sites and the role of polysaccharides, proteins and lipids in gold(ill) uptake. The mode of gold binding is suggested as being initially ionic, this is very rapid, with the interaction of the anionic complex, [AuCI₄]". with the cationic biomass (PH 2). This eventually leads to the displacement of the chloride ligand(s) initiating covalent binding. Spectral studies of the chemical interaction between gold and the representative tannins indicated the protonated hydroxy groups to be responsible. All evidence suggests that the binding mechanisms of gold are not simple. Preliminary adsorption studies of platinum by Azalia filiculaides were conducted. Batch studies indicated that J gIL biomass concentration, initial platinum concentration of 20 mgIL and pH 2 are optimal, while the column studies indicated a flow-rate of! 0 rnL/min and initial platinum concentration of 20 mgIL as optimal. In the platinum effluent study, platinum showed a removal of 23 % and 2 J % for the batch and column studies respectively. Again adsorption was accompanied by //' release. Azalia filiculaides demonstrated its feasibility in the removal of gold and platinum from simulated as well as waste water solutions. Its potential viability as a biosorbent was demonstrated by the high recovery from synthetic solutions of greater than 99% for gold (2-10 mgIL), and greater than 89% for platinum (20 mgIL).

Abstract:
In this thesis, the bioconversion of palladium and gold solutions and gold-bearing wastes into highly valuable mono- and bimetallic catalysts is described. This process relies on bioreduction; the ability of some bacteria to reduce Pd(II) and Au(III) ions at the expense of an exogenous electron donor with precipitation as zero valent metals. The resulting metallic nanoparticles (NPs) immobilised on the outer membrane and within the periplasm exhibit remarkable catalytic properties, sometimes surpassing commercially available catalyst formulations in terms of activity and/or selectivity. Previous studies in the field have mainly focused on the ability of Desulfovibrio spp. to reduce Pd(II) from both surrogate solutions and reprocessing wastes. The mechanism of Pd(II) reduction in this genus was previously shown to be enzymatic, involving hydrogenases, key enzymes of hydrogen metabolism. In this study, a detailed investigation into the mechanism of Pd(II) reduction by Escherichia coli using a genetic approach confirmed hydrogenase involvement and additionally showed that these enzymes are needed to initiate the formation of Pd(O) nuclei. Genetically engineered strains depleted of all functional hydrogenases lost their ability to produce Pd(O) NPs, which in turn greatly affected the catalytic activity of the resulting bioinorganic catalyst ("bioPd(O)"). Further studies suggested that the nature of the bacterial support also influenced the catalytic activity of bioPd(O) preparations. Seven bacterial strains, representing different Gramnegative and Gram-positive genera, were tested for Pd(II) reduction. Large differences in Pd(II) sorption and Pd(II) reduction ability were observed between strains; the combination of these factors affected the final size distribution of the cell-bound Pd(O) NPs and hence the catalytic activity of the resulting bioPd(O) preparations. Bioinorganic catalysts were shown to be active and/or selective in a wide variety of reactions, including Cr(VI) reduction, hydrogenolysis (reductive dehalogenation), Heck coupling and oxidations. The bioreductive approach was applied to demonstrate Au(III) reduction and recovery using cells of D. desulfuricans and E. coli and the first evidence of the catalytic activity of biogenic Au(O) NPs is presented. Au(III) reduction was slower than Pd(II) reduction and only partially involved hydrogenases which suggested the involvement of an additional different reduction route. However, introducing a bionanocatalyst consisting of lightly pre-palladized cells into the process greatly improved the speed of Au(III) reduction and resulted in the formation of highly ordered AulPd core/shell nanostructures which exhibited catalytic properties not seen with traditional chemical counterparts.

Mestrado em Sistemas Energéticos Sustentáveis
The current project assesses potential molten alloy anodes for Solid Oxide Fuel Cells (SOFC) running on solid waste. A detailed phase diagram study was performed to locate probable anode systems. The molten metal oxide system PbO-Sb2O3 was selected as a possible molten alloy anode for this application. A detailed vapour pressure study of this system was performed. Several cells were fabricated to experimentally assess the electrochemical properties of this system. The work reveals several unexpected limiting features such as the incompatibility between the platinum and the chosen alloy. A second cell was built, this time using rhenium wires instead, preventing such reaction. However, the rhenium wire sublimes under oxidizing conditions (air) and the sealing glass and the chosen alloy system react with each other under long term use. Considering all these issues, a third cell design was conceived, surpassing some obstacles and providing some initial information regarding the electrochemical behaviour. The current project shows that many parameters need to be taken into account to ensure materials compatibility. For the PbOSb2O3 system, the high volatility of Sb2O3 was a serious limitation that can only be addressed through the application of new contact wires or sealing materials and conditions. Nonetheless, the project highlights several other potential systems that can be considered, such as Pb11Ge3O17, Pb3GeO5, Pb5Ge3O11, Bi2CuO4, Bi2PdO4, Bi12GeO20.
Este estudo incidiu sobre potenciais ânodos líquidos de ligas metálicas para células electrolíticas (do tipo SOFC) alimentadas por resíduos sólidos. Alguns sistemas de ânodos possíveis foram identificados através de um estudo detalhado de diagramas de fase. O sistema de óxidos metálicos PbO-Sb2O3 foi selecionado como uma possível liga metálica para esta aplicação. Este sistema foi sujeito a um estudo detalhado de pressão de vapor. Algumas células foram fabricadas para avaliar experimentalmente as propriedades electro-químicas deste sistema. Este trabalho revela imensas características que inesperadamente limitaram este estudo, tal como a incompatibilidade entre platina e a liga metálica escolhida. Uma segunda célula foi construída, desta vez usando um fio de rénio, prevenindo tal reacção. No entanto, o fio de rénio sublima sobre condições oxidantes (ar) e, perante um uso prolongado, o vidro selante e a liga metálica reagem entre si. Considerando todas estas incompatibilidades, um terceiro modelo de célula foi criado, ultrapassando alguns obstáculos e fornecendo alguma informação inicial relativa ao comportamento electro-químico. O presente trabalho mostra que vários parâmetros precisam precisam de ser abordados de modo a assegurar a compatibilidade dos materiais. Relativamente ao sistema PbO-Sb2O3, a elevada volatilidade de Sb2O3 foi uma grave limitação que só pode ser contornada através da aplicação de novos fios conectores, materiais e condições de selamento. No entanto, este projecto destaca outros potenciais sistemas que podem ser estudados, como Pb11Ge3O17, Pb3GeO5, Pb5Ge3O11, Bi2CuO4, Bi2PdO4, Bi12GeO20.

Thesis (BTech (Surface Design))Cape Peninsula University of Technology, 2010
The purpose of this research is to explore and create an understanding of how architectural structures. that adhere to deconstructivist design principles, can inspire the reconstruction of second-hand school fumiture and scrap metal. The planned pieces will continue to create an awareness of sustainability, by designing for reuse. These functional fumiture pieces of low tables and chairs will be handcrafted, appealing to a niche market, or specific spaces and they will act as expressions of contradiction. This research will act as an addition to a body of knowledge, where I will primarily focus on contradicting the traditional form and aesthetic of furniture design. I have decided to create these functional pieces to express a new possible direction of furniture design. The study context is a potential confrontational experience in that I want to challenge the conventional form and aesthetics of fumiture design. These pieces of fumiture will be placed in a niche market where they will exist as one-offs that are not produced for mass-consumption, as they will be individually hand-erafted. These days more and more people are attempting to live in a more sustainable manner by practicing to reduce our consumption of products and resources; reuse that which we have disposed of and forgotten as consumers and to recycle waste products and transform them into a feasible afterlife (Martin, 2010). The theory is focused on Sohaill Inayatullah's theory of "Futures Thinking", and this .theory is further supported by Victor Margolin's study of changing existing situations into preferred ones. The research further reflects on Jacques Derrida's theory of deconstruction, and this research is further supported by the theory of sustainability, by designing for reuse, with a focus on Ezio Manzini. Therefore, my research study is concerned with confronting and challenging the conformity that the form of furniture and its aesthetic adhere to.

Abstract:
AbstractThe future sustainable built environment focuses mainly on environmental conservation and technological innovation and development. However, with infrastructure development, the consumption of raw materials such as cement, gypsum, sand, and stones increases. Therefore, use of industrial waste as raw material in construction shall be proposed as a sustainable and environment friendly alternative. Also, the higher demand for mineral commodities have led to increased mining and hence increased mining waste. The mine tailings being the wastes from rocks and minerals processing, are generally rich in Si, Ca, Al, Mg, and Fe, and also have considerable amounts of heavy metals and metalloids such as Pb, As, Co, Cu, Zn, V, and Cr. When tailings contain sulphide minerals, it may also lead to acid mine drainage. This makes the effective and efficient recycling and reuse of mine waste a major environmental concern. However, the physical, mineralogical and chemical composition of the mine tailings renders it a suitable material for use in civil engineering applications. This paper discusses the use of mine tailings of different origins for different civil engineering applications such as bricks, ceramics, fine aggregates, coarse aggregate and cementitious binders. This approach has a potential to reduce the demand on existing natural resources to face the demands of the exponentially developing infrastructure.

Abstract:
At KAERI (Korea Atomic Energy Institute), radioactive soil and concrete wastes with extremely low level of activity were regulatory cleared in 2008 and large amount of spent drums remained. After generation, drums having good physical integrity reused for packaging radioactive wastes and about 50 tons of drums unsuitable for reuse were stored as radioactive wastes. Having once been used for packaging regulatory cleared radioactive wastes, these spent drums were determined to be regulatory cleared. Before regulatory clearance, steel drums were radiation monitored, washed with pressurized water two times, compacted and stored at a designated area. Based on radiological dose assessment results using a recycling scenario derived from actual situation, the regulatory clearance of steel drums was permitted by the regulatory body. Treatment of the regulatory cleared drums was then committed to a scrap-metal dealer for recycling. In this study, a process of regulatory clearance for spent steel drums and a modified radiological dose assessment model for staff members of a scrap-metal dealer will be discussed.

Abstract:
When decommissioning nuclear installations, large quantities of metal components are produced as well as significant amounts of other radioactive materials, which mostly show low surface contamination. Having been used or having been brought for a while in a controlled area marks them as ‘suspected material’. In view of the very high costs for radioactive waste processing and disposal, alternatives have been considered, and much effort has gone to recycling through decontamination, melting and unconditional release of metals. In a broader context, recycling of materials can considered to be a first order ecological priority in order to limit the quantities of radioactive wastes for final disposal and to reduce the technical and economic problems involved with the management of radioactive wastes. It will help as well to make economic use of primary material and to conserve natural resources of basic material for future generations. In a demonstration programme, Belgoprocess has shown that it is economically interesting to decontaminate metal components to unconditional release levels using dry abrasive blasting techniques, the unit cost for decontamination being only 30% of the global cost for radioactive waste treatment, conditioning, storage and disposal. As a result, an industrial dry abrasive blasting unit was installed in the Belgoprocess central decontamination infrastructure. At the end of December 2006, more than 1,128 Mg of contaminated metal has been treated as well as 313 Mg of concrete blocks. The paper gives an overview of the experience relating to the decontamination of metal material and concrete blocks at the decommissioning of the Eurochemic reprocessing plant in Dessel, Belgium as well from the decontamination of concrete containers by abrasive blasting.

At the end of May 2001, after 6 years of operation, 523 Mg of contaminated metal has been treated. 182 Mg of this material was unconditionally released, having been monitored twice by the in-house health physics department. About 303 Mg of the metal, presenting surfaces that could not be measured due to their shape, were melted for unconditional release in a controlled melting facility. The suitability of the abrasive blasting system was verified, and it was proved that there was no intrusion of contamination into the material surface. The paper gives an overview of the experience relating to the decontamination of metal material by abrasive blasting at the decommissioning of the Eurochemic reprocessing plant in Dessel, Belgium.

Abstract:
The development of cost-effective and green recycling technologies for secondary metal recovery from industrial wastes is one of the new challenges on the sustainable development agenda. By incorporating cost and resource efficiency assessment into the technology innovation process, we aim to improve the sustainability of new recycling technologies by minimizing process waste, improving resource efficiency, thus reducing the recovery process cost. This paper focuses on modeling and assessing the production cost and resource use efficiency for closed-loop nickel recovery from spent hydrogenation catalysts. The engineering economics factors and process variables that affect the profitability and resource efficiency of nickel recovery are identified. They are modeled in cost and efficiency metrics. Model-based scenarios assessment revealed that compared to open-loop nickel recovery, the closed-loop concept delivers more cost-effective and greener recycling solutions. The closed-loop process cost reduction via efficient resource use and process waste minimization is in the range of 18.4% to 24.0% compared to the open-loop process option.

Full text
Abstract:
All incineration and other thermal treatment technologies produce flue gas treatment residues (FGTR) that require specialised treatment and disposal. In the United Kingdom the FGTR arising from municipal solid waste incineration is classified as a hazardous (special) waste. This is primarily due to the irritant properties of chloride, but also due to the content of heavy metals. These wastes must be handled, transported & disposed of in accordance with the Special Waste Regulations 1996 and are disposed into highly engineered landfill sites, which isolate the material from the environment. The low levels of trace elements in the FGTR mean that the recycling of the metallic elements is not economic. Control through stabilisation and encapsulation in a crystalline matrix converts the FGTR primary form from a powder into solid block form. The use of a novel metal matrix encapsulation (MME) process allows low level engineering processes to be employed, increasing a range of reuse options combined with long-term improved storage.

Full text
Abstract:
A decommissioning program “RECYCLE SIMULATOR” should be put into practice in careful consideration of both recycle of non-radioactive wastes and reduce of radioactive wastes in the coming circulatory social system. Nevertheless current support systems for decommissioning planning mainly deal with decontamination, safety storage and dismantlement, so-called the prior part of the total decommissioning process. Authors emphasize the necessity of total planning of decommissioning including recycle or reuse of a large amount of demolition materials and are propelling the development of the multi expert system named “RECYCLE SIMULATOR”. This paper presents an algorithm of the recycling and reusing scenario of demolition materials and a summarized configuration. RECYCLE SIMULATOR for the demolished concrete was developed in 2000 and presented at 10th International Conference on Nuclear Engineering (icone10). Construction of a supporting multi expert system for the totally planning of decommissioning projects is objected by expansive development of the previous version. Main conclusions obtained from this paper are under this. (1) The previouslly developed expert system was advanced in its estimational function toward the satisfaction of decommissiong planners. (2) The applicability of the system was enlarged to all the radioactive and non-radioactive wastes, demolished metal and concrete products, in a corresponding site of decommissioning. (3) Finally decommissiong recycle simulator was completed in a harmonized unification.

Abstract:
Best Practicable Environmental Option (BPEO) and Best Practicable Means (BPM) are concepts well established in the nuclear industry to help guide and inform waste management decision making. The recycling of contaminated metal waste in the UK is not well established, with the majority of waste disposed of at the Low Level Waste Repository (LLWR) at Drigg. This paper presents an overview of the Strategic BPEO study completed by Studsvik examining the options for low level metal waste management and a subsequent BPM study completed in support of a proposed metals recycling service. The environmental benefits of recycling metals overseas is further examined through the application of lifecycle analysis to the metals recycling process. The methodologies used for both studies are discussed and the findings of these studies presented. These indicate that recycling contaminated metal is the preferred option, using overseas facilities until UK facilities are available. The BPM for metals recycling is discussed in detail and indicates that a tool box for processing metal waste is required to ensure BPM is applied on a case by case basis. This is supported by effective management of waste transport and waste acceptance criteria. Whilst the transport of contaminated metal overseas for treatment adds to the environmental burden of metals recycling, this when compared with the production of virgin metal, is shown to remain beneficial. The results of the Studsvik studies demonstrate the benefits of recycling metals, the options available for such a service and challenges that remain.

Abstract:
Building 220 at Harwell was built by the Ministry of Works as a Radiochemical Research and Development facility in the latter part of the 1940’s. The facility has been operational since 1949 and has been extended several times, most notably the Plutonium Glove Box Wing in the 1950’s and the Remote Handling Wing in the 1980’s. Only the Remote Handling wing remains operational, processing Historic Waste which is being recovered from storage holes elsewhere on site. The remainder of the facility is undergoing progressive strip out and decommissioning. In the Plutonium Wing and associated areas the waste ‘fingerprint’ (nuclide vector) consists predominately of alpha emitting radionuclides. Decommissioning and Decontamination (D&D) operations often result in the production of large volumes of scrap metal waste with little or no radioactive contamination. Proving that the waste is clean can be costly and time consuming, as the shape and size of the metallic waste items often means that it is difficult or impossible to monitor all surfaces using conventional hand-held survey meters. This is a particular problem for alpha contamination measurement. Traditional radiological surveying techniques are very labour intensive and involve surveyors checking every surface using hand held instruments and smear sampling the hard to access areas. Even then 100% monitoring cannot be guaranteed. An alternative to traditional methods is the Long Range Alpha Detection (LRAD) technique which remotely detects and measures secondary ionization created in air by alpha particle interactions, allowing extremely low levels of alpha contamination to be measured. A survey system, IonSens®, using the LRAD technique, was developed by BNFL Instruments Ltd (now Babcock Nuclear) which allows rapid surveying of scrap metal for alpha contamination at very low levels. Two versions of this system exist but both essentially comprise a measurement chamber into which scrap metal is placed and sealed while a measurement is carried out. Research Sites Restoration Ltd (RSRL) has purchased an IonSens® system with a single 2m long measurement chamber. This instrument is optimised for clearance monitoring of pipework of up to 150mm diameter. Testing and use of support baskets has enabled the instrument to be used as a clearance monitor for a wide range of metallic waste including hand tools. This paper illustrates how the instrument, and a robust consignment procedure, has been used to justify the clearance of several tonnes of metal wastes for recycling rather than paying for disposal of this material as low level waste.

Abstract:
Most every one of the approximate 90 operating waste-to-energy facilities in North American have a ferrous metals recovery system to extract these metals from the ash stream before the ash is disposed as a waste. Recovery of this ferrous metal obviously reduces the significant landfill disposal cost and associated ash hauling cost for the facility by reducing the volume of materials being disposed. The volume of the ferrous metals stream typically ranges between 1.0 to 4.0 percent of the incoming waste volume. But for facilities which manage hundreds of thousands of materials per year, this relatively small stream of material in many facilities present such a nuisance that the operators at some plants have a penchant not to bother with it for the tenuous value they have received. The value received has been exposed to extreme variations and uncertainty due from the fragmented scrap metal markets, transportation costs, quality of the recovered product (or lack thereof), cost of recovery, and a number of other constraints and issues, some in the control of the facility operator and some not in the control of the operator. As a result, the attention given to this area is also very variable across facilities, even within the same parent company.
