Abstract:
In the current state of huge waste production and energy crisis, there is a need to find additional alternate energy resources and options for waste management. The present study was designed to measure the potential of different fruit wastes to serve as substrate for lipid accumulation in oleaginous bacteria. For this purpose, three novel bacterial strains (AF3, KM1 and KM10) isolated from the crude oil samples were systematically compared for their lipid accumulation potential using three types of waste including orange waste (OW), mango waste (MW) and apple waste (AW). Using waste as sole substrate, it was observed that maximum lipid accumulation by each strain was above 20%, which confirms that the bacteria belong to the oleaginous group. However, each bacterial isolate represented differential accumulative capacity with varying organic matter removal efficiency. Maximum lipid accumulation was achieved by KM10 (>25%) with AW as substrate, and KM1 (>24%) with MW as substrate; however, AF3 represented only 21% lipid accumulation using AW as substrate. Similarly, the maximum removal efficiency was recorded for KM10 in AW, followed by OW, where >60% and >50% of volatile solids (VS) removal, respectively, were achieved over the period of 7 days of incubation. This showed that the oleaginous strains also exhibit excellent waste treatment efficiency. The 16s RNA gene sequencing results showed that these KM1 and KM10 strains were Serratia surfactantfaciens and Serratia liquefaciens. In the end, a circular economy model was presented to highlight the significance of the mechanisms, which offers dual benefits over the linear economy model. Overall, the findings of the present study revealed that the novel oleaginous strains not only provide considerable lipid accumulation, but are simultaneously capable of low-cost waste treatment.

Abstract:
A tourist attraction serves as a recreational vacation destination for both locals and foreign tourists. Tourism is therefore encouraged to grow as a result of this condition. However, there is an accumulation of plastic waste in tourist attractions. According to NatGeo's research, plastic waste was found at Kedonganan Beach, Bali, in 2019. A projection indicates that in 2050 there will be an accumulation of 12 trillion plastic wastes if the accumulation of plastic wastes is not prevented. The lack of care and awareness between the community, government and managers makes tourist attractions polluted. The amount of waste also makes the community around the tourist attractions directly affected. Therefore, it is necessary to educate about the prevention of plastic waste accumulation. Through, animated video media becomes an intermediary media for delivering information. This animation can help realize how important it is to preserve nature, especially tourist attractions to the community.

Abstract:
Earth is constantly subjected to dramatic changes due to uncontrolled human activities and this has led to climatic variations associated with global warming resulting in unparalleled greenhouse gas emissions. One of the major causes is solid waste accumulation by human activities ranging from agricultural to industrial activities. The relation between solid waste and climatic change had forced scientists to propose a solid waste management plan to reuse, recycle and create energy from solid waste preventing its accumulation and subsequent pollution. When we consider human activities which are environmentally hazardous; plastic waste accumulation, agricultural wastes disposal and fossil fuel burning holds prominent positions. Plastic wastes. The accumulation of plastic wastes and agricultural wastes pose serious problems of disposal. Plastic wastes are often incinerated or left to be dumped in landfills. Similarly, agricultural wastes are also burnt, releasing a lot of toxic gases into the atmosphere. A common solution to curb both the problems is to streamline the production of bioplastic using agricultural waste (mostly lignocellulose) as a substrate. The third major environmental threat is the increased motor vehicle emission leading to air pollution associated with health threat. The extent of risk ranges from carcinogenic and noncarcinogenic health effects. Carbon dioxide emission by the increasing use of fossil fuels by ever increasing world population not only depletes the resource but also will result in anthropogenic climate change. Therefore, utilization of lignocellulosic waste material as raw material for monomers for bioplastic as well as for bioethanol production can be considered as a productive approach to address all the three problems mentioned above. In addition utilization of fermentation residue after bio products extraction can be used as a soil enriching agent. The intention is converting lignocellulosic waste to zero waste.

Abstract:
Purpose. To analyze the situation with the generation, utilization and accumulation of industrial wastes, to develop the mathematical model of forecasting and, using this model, to identify the main trends in forming and accumulating waste for next years and current threats. Methodology. In the scientific research presented in the article, general and special methods of cognition were applied. For the use of the indicated methods complex approach was applied. Complex use of methods of regular supervision, comparative analysis, content analysis, and logical generalization, quantitative and qualitative comparison allowed not only determining the range of industries that make a major contribution to the formation of existing industrial wastes, but also proving that the main polluter is the extractive industry. Complex use of methods of scientific abstraction and mathematical formalization allowed not only creating a mathematical model for the formation of forecasts for industrial wastes for subsequent periods but also strengthening their relevance by highlighting the colored noise and predicting trends in the coming years. Findings. The results of quantitative and qualitative analysis of the annual increase in industrial waste by industries prove the mono-sectoral impact on the formation of the crisis situation. Threats have been detected of multiplicative year-on-year growth of waste accumulated during operation in specially designated places and facilities and annual growth of accumulation of dangerous industrial waste of IIII classes. The created mathematical model allowed carrying out forecasting of volumes of formation and utilization of industrial waste. Due to this, further analytical studies have shown that the volume of waste generation in recent years is twenty times as much as the volumes of disposal. There has also been a catastrophic decrease in the rate of dangerous waste disposal and outpacing the growth of total waste accumulation. Originality. As a result of the analysis, it is found that the trend of recent years to increase waste generation has been formed due to the extractive industry and quarry development. Threats of a crisis situation formation as a result of the reduction of dangerous waste utilization and the multiplicative year-on-year growth of the total accumulated wastes have been established. During the research, a mathematical model was developed for the analysis of waste generation and utilization and forecasting of their volumes. Practical value. The results of quantitative and qualitative analysis of the annual increase in the volume of industrial wastes by industries prove the mono-sectoral impact on forming of the crisis situation. The application of the developed mathematical model of forecasting of volumes of waste formation and utilization provides new opportunities for the analysis of the situation and introduction of advanced methods of waste management.

Abstract:
Sites for the accumulation of solid municipal waste on the territory of settlements affect the densification of buildings, the reduction of the area of recreational areas, the shortage of car parking spaces. Solid municipal waste accumulation sites are a reserve of land resources. With optimal planning of placement, modern technical equipment, the accumulation sites of solid municipal waste can be reduced. The article discusses the experience of work on the creation of a "Geoinformation database on information about the sites of accumulation of solid municipal waste in the territory of the city of Novosibirsk." Planning of optimal and environmentally safe placement of solid municipal waste accumulation sites has been carried out. Examples of digital models of the location of solid municipal waste accumulation sites on the territory of the city of Novosibirsk are shown. The description of the information contained in the geoinformation database of solid municipal waste accumulation sites is given. It is concluded that the geoinformation database on the data on the sites of solid municipal waste accumulation is a new information product, which contains information on the qualitative, quantitative and spatial characteristics of the sites of solid municipal waste accumulation. Thanks to the possibility of combining data on solid municipal waste accumulation sites with an electronic map of the city, a new original geoinformation product has been created that allows planning the location, as well as requirements for land plots on which solid municipal waste accumulation sites will be located. The logistical tasks of organizing garbage collection will be solved.

Abstract:
Improving the hydraulic performance of waste stabilization ponds (WSPs) is an important management strategy to not only ensure protection of public health and the environment, but also to maximize the potential reuse of valuable resources found in the treated effluent. To reuse effluent from WSPs, a better understanding of the factors that impact the hydraulic performance of the system is needed. One major factor determining the hydraulic performance of a WSP is sludge accumulation, which alters the volume of the pond. In this study, computational fluid dynamics (CFD) analysis was applied to investigate the impact of sludge layer geometry on hydraulic performance of a facultative pond, typically used in many small communities throughout the developing world. Four waste stabilization pond cases with different sludge volumes and distributions were investigated. Results indicate that sludge distribution and volume have a significant impact on wastewater treatment efficiency and capacity. Although treatment capacity is reduced with accumulation of sludge, the latter may induce a baffling effect which causes the flow to behave closer to that of plug flow reactor and thus increase treatment efficiency. In addition to sludge accumulation and distribution, the impact of water surface level is also investigated through two additional cases. Findings show that an increase in water level while keeping a constant flow rate can result in a significant decrease in the hydraulic performance by reducing the sludge baffling effect, suggesting a careful monitoring of sludge accumulation and water surface level in WSP systems.

Abstract:
Waste, that is any matter whether gaseous, liquid or solid or any combination thereof, originating from any residential, commercial or industrial area identified as undesirable or superfluous by-product, emission, residue or remainder of any process or activity tends to be a hazard to the environment. Waste is generated in all processes which transform materials from one state, form or medium to another. The management of waste in the Sedibeng District Municipality is a very complex problem. There are many reasons for this and these include: the diverse and voluminous waste stream; progressive accumulation of waste in the environment; large numbers of unpermitted waste disposal sites; the severe shortage of hazardous waste disposal sites and shortage of personnel in local municipalities qualified to implement existing legislation. The accumulation of waste in the district not only poses a serious and growing threat to health and quality of life, but also causes infrastructural damage such as the blocking of storm water drains and sewer by litter which ultimately leads to costly road and pavement destruction and increase in maintenance costs. The objective of the study was to investigate waste management activities in the Sedibeng District Municipality and to explore best practices as strategies for recommendations. The Sedibeng District Municipality comprises three local municipalities namely the Emfuleni, Lesedi and Midvaal Local Municipalities. Due to the fact that the Municipality forms part of the industrial hub of the Gauteng Province, there has been an excessive influx of the people into the district and, as a result, more houses had to be built and more normal urban services such as electricity, sanitation, water and waste, had to be provided. The study intended to investigate different waste management strategies that are employed by the three local municipalities that could help reduce the impacts and volumes of waste that are generated by residents before such waste could pollute the environment. A further objective was to explore possible waste reduction mechanisms such as recycling that can help reduce waste volumes before they reach the disposal site. Arising from the problem statement on waste management for this study, it is important that the locus of this study be directed towards the solution of the problem on waste management activities in the Sedibeng District Municipality The following hypothesis was accordingly formulated: Waste management strategies and practices as currently practised in the Sedibeng District Municipality are obsolete, outdated and inadequate to attain a cleaner environment and as a result, there is a need to explore the development of more cost effective strategies in waste management. Comparative study of the different strategies that are employed in the three local municipalities as well as the challenges they face when providing the required service, were made. Similar study was applied to the achievements that are recorded as findings of the study. The challenges and success stories highlighted in the study were found through the use of questionnaires that were distributed to respondents in the three local municipalities. Questionnaires for the study were compiled for both councilors and municipal officials. The research instruments for the study included questionnaires, interviews and consultations with members of the community. Further technique was participant observation, the researcher being responsible for the provision of refuse removal services to the Evaton and Sebokeng communities. Amongst others, it was found that: discrepancies existed in the waste management processes and these include the following: • There was a serious problem of personnel shortage in municipalities as a result of financial constraints that led to nonreplacement of personnel who went on retirement, resigned or died; • Existing equipment do not compliment the growing population figures as well as the sizes of the municipality and as a result, residents opted to dump waste at their backyards as an alternative procedure for disposal of waste from their homes, and • Problems attributed to illegal dumping increase each day and their resolution will be a function of implementation of compliance with legislation. • Community awareness of refuse collection schedule is at minimum, a situation which leads to illegal dumping of waste, and • Tariff on refuse removal is deemed to be prohibitive to African residential areas. The study ends with recommendations for management action on waste, and for further research.<br>Thesis (Ph.D. (Public Management and Administration))--North-West University, Vaal Triangle Campus, 2010.

Abstract:
Thesis (MTech (Agriculture))--Cape Peninsula University of Technology.<br>During the past years government regulations concerning winery effluent became stricter to protect the environment. Wineries are continually improving wastewater management and finding appropriate ways to reduce cellar effluent. Due to water scarcity in South Africa, it could be a huge advantage if winery effluent could be used as irrigation water for vineyards. If the industry can re-use the untreated wastewater, it will not only save a huge amount of irrigation water, but it will also be able to get rid of the vast amount of cellar effluent. Grape production plays a major role in agriculture worldwide. The world production of grapes worldwide in 2013 was 751 MgL. South Africa is the 9th biggest wine producer in the world with 10 X 10HL of wine. In the earlier years of wine production in South Africa, the small volumes of winery wastewater did not have a negative impact on the environment but with the increased volumes over the last years, the possibility of contamination of the soil and the environment has increased. Government decided to regulate the irrigation of cellar effluent with the National Water Act of 1998 as approved by the Department of Water Affairs (DWAF). There are different ways to get rid of cellar effluent. One successful way is by constructed wetlands where plants are used to break down minerals which could be detrimental to the environment. This is a successful way to get rid of cellar effluent but could take up to six weeks before the mineral contents can be broken down by the plants. Another way is to use bio-reactors to break down the contents of the cellar effluent, but this is expensive. Wastewater consists of important nutrients needed for plant growth such as macro-nutrients like N, P, K and micro-nutrients like Fe, Zn, Mn and Cu and a substantial amount of organic matter. If cellar water, just like domestic wastewater is used for irrigation the farmer can save water when he uses less fertiliser, because of the high nutrient content in the cellar effluent. If cover crops such as oats (Avena sativa L. cv. Pallinup) in winter and pearl millet (Pennisetum glaucum (L.) R. Br.) in summer can be used to remove excess cations, as well as unwanted chemicals such as toxic metals from the soil, it may result in effluent water with a higher chemical oxygen demand (COD) level than the current legal limitations that can be used to irrigate the vineyard. The aim of this project was, therefore, to determine the ability of oat and pearl millet cover crop to remove excess minerals from the soil irrigated with augmented water at different COD levels, without a negative effect on growth and yield of the vineyard or wine quality. Field trials were carried out in a Cabernet Sauvignon/99 Richter vineyard established on a sandy soil at the Goudini Cellar near Rawsonville.

Abstract:
Elevated levels of trace elements in the environment are of great concern because of their persistence, and their high potential to harm living organisms. The exposure of aquatic biota to trace elements can lead to bioaccumulation, and toxicity can result. Furthermore, the transfer of these elements through food chains can result in exposure to human consumers. Sea-fill or coastal fill sites are among the major anthropogenic sources of trace elements to the surrounding marine environment. For example, in the Maldives, Thilafushi Island is a sea-fill site consisting of assorted municipal solid waste, with multiple potential sources of trace elements. However, there is limited data on environmental trace element levels in the Maldives, and although seafood is harvested from close to this site, there is no existing data regarding trace element levels in Maldivian diets.

Abstract:
En aquesta Tesi hem investigat sis canyons submarins situats als marges continentals català central (canyó submarí del Foix) i del nord (canyons submarins del Cap de Creus, la Fonera i Blanes), i del sud de Califòrnia (canyons submarins de Santa Mònica i Redondo), amb la finalitat d’aprofundir en el coneixement dels processos de transport sedimentari que s’hi produeixen, de les seves resultants morfosedimentàries de detall, i del paper que juguen en la transferència i acumulació de deixalles d’origen antròpic. Per assolir allò que preteníem hem utilitzat dades de batimetria de multifeix i de sísmica de reflexió de molt alta resolució adquirides amb mètodes ara ja convencionals, des de vaixells en superfície, i amb un vehicle subaquàtic autònom (AUV), i també imatges obtingudes in situ amb un vehicle subaquàtic operat remotament (ROV). Els resultats assolits han estat publicats en tres articles que formen el cos d’aquesta Tesi, els quals resumim breument en els paràgrafs següents. L’estudi morfomètric detallat del canyó del Foix ha permès il·lustrar la complexitat de les xarxes de drenatge dels talussos de marges continentals passius, comparables en certa mesura a les xarxes fluvials. El principal element que contribueix a la complexitat morfològica, i també a la jerarquització, de les lleres que conformen els sistemes de canyons submarins són els xaragalls de vessant, l’evolució dels quals a hores d’ara resulta de l’acció subjacent de fluxos gravitatius i de les interferències provocades per l’acció de l’home sobre el fons, en especial per la pesca de ròssec. La modelització de la xarxa de drenatge i la seva parametrització morfomètrica subseqüent permeten quantificar i analitzar objectivament la forma, la mida, el patró de desenvolupament i la capacitat de transport del conjunt de lleres que conformen un sistema de canyó submarí i, per tant, discriminar les rutes de transport principals. L’estudi d’altíssima resolució de la geomorfologia i el recobriment sedimentari més superficial dels canyons submarins de Santa Mònica i de Redondo, a Califòrnia, ens ha permès resoldre el significat de les formes de fons observades i interpretar els processos responsables del seu desenvolupament. Destaquen especialment una successió d’ones de sediment rítmiques al fons del canyó de Redondo i un conjunt de cicatrius erosives al curs inferior del canyó de Santa Mònica. Pel que fa a les ones de sediment, l’anàlisi acurada d’aquestes formes de fons sedimentàries ha permès provar la seva migració ascendent, només explicable per l’acció de corrents de terbolesa, les quals a més de transportar sediment també n’intercanvien amb la llera del canyó, fet determinant del tipus d’empremta generada. Hem identificat els tipus de deixalles presents als canyons del Cap de Creus, la Fonera i Blanes, analitzant-ne també llur distribució i abundància. A partir d’aquestes observacions hem mirat d’escatir quins són els processos hidrosedimentaris responsables del transport de les deixalles cap als trams intermedis i distals dels canyons investigats. A partir de la categorització de les deixalles, hem aproximat els seus orígens i vies d’entrada al medi marí, que té lloc al llarg de la línia de costa en el seu conjunt, comptant també amb l’acció del vent, i puntualment per les desembocadures fluvials, i mar enfora per efecte de l’activitat pesquera i de la navegació recreativa i de transport de mercaderies. Els plàstics, lleugers i fàcils de transportar per la dinàmica marina, i les restes d’arts de pesca, resultants de l’aprofitament històric intensiu dels recursos vius de la zona, són els tipus de deixalles més abundants. La interacció entre deixalles i organismes és ambivalent, doncs hem observat que tan pot ésser perjudicial com beneficiosa. On més gran és l’acumulació de deixalles, si més no en nombre d’ítems, és preferentment a profunditats superiors als 1.000 o 1.500 m, segons el canyó considerat. D’acord amb els patrons de distribució observats i els processos hidrosedimentaris que ocorren al marge català del nord, considerem que les cascades d’aigües denses de plataforma i els grans temporals de llevant són els principals causants de la transferència de deixalles canyó avall. Aquesta interpretació se sosté per la capacitat d’aquests processos per resuspendre, remobilitzar i transportar de manera altament eficient i en grans volums aigua densa, sediments i, pel que es veu, substàncies estranyes com les deixalles des de la plataforma continental fins la conca profunda, a més de 2.000 m. Els tres articles de la nostra Tesi proporcionen una visió més amplia i més transdisciplinar dels processos hidrodinàmics que operen als canyons submarins, de les morfologies generades i dels efectes colaterals d’aquests processos en l’actual periode Antropocè, caracteritzat per l’abast de la petjada humana arreu del planeta. En aquest aspecte concret, el de la petjada humana als fons marins profunds, és de plena aplicació la idea de que “no per poc conegut, és menys rellevant”. Per tant, la nostra Tesi també conté un crit d’alerta front al caràcter estès de l’impacte antropogènic a l’ambient marí. En aquest marc, conèixer el funcionament dels canyons submarins assoleix encara més transcendència, doncs no es tracta només de Geologia, o de Sedimentologia, sinó que va molt més enllà.<br>In this PhD Thesis we have investigated six submarine canyons located in the central (Foix submarine canyon) and north (Cap de Creus, la Fonera and Blanes submarine canyons) Catalan continental margins, and in the continental margin of Southern California (Santa Monica and Redondo submarine canyons). Our main aim has been to improve the understanding of sediment transport processes within the canyons, unveil the resulting morphologies, and illuminate their role in the transfer and accumulation of marine litter. Our dataset was obtained by means of state of the art high-resolution multibeam bathymetry and seismic reflection systems from surface vessels and an advanced autonomous underwater vehicle (AUV), jointly with an underwater remotely operated vehicle (ROV) that provided in situ seafloor imagery. The main results obtained have been published in three scientific papers that form the core of this PhD Thesis, which are briefly summarized in the following paragraphs. The detailed morphometric study of the Foix Canyon has shown the complexity of drainage networks on the slopes of passive continental margins, which are comparable to some extent to fluvial networks. The modelling of the drainage network and their subsequent morphometric parameterization allow to objectively quantifying and analysing the shape, size, pattern of development, and the transport capacity of all channels that make up a submarine canyon system and therefore discriminate major transport routes. The high-resolution analysis of the geomorphology and sediment cover of the Santa Monica and Redondo submarine canyons, in California, has allowed understanding the significance of the observed bedforms and subsequently interpreting the processes responsible for their development. We have identified the types of litter present in Cap de Creus, Fonera and Blanes canyons, also analysing their distribution and abundance. Plastic, which is lightweight and easy to carry by ocean dynamics, and lost or dumped fishing gear resulting from intensive historical exploitation of living resources in the area, are the most abundant types of litter. The interaction between organisms and litter is ambiguous, as it has been observed to be both detrimental and beneficial. Litter accumulation is larger, at least in number of items, at depths in excess of 1.000 or 1.500 m, depending on the canyon considered. According to the observed patterns of distribution and the hydrosedimentary processes occurring in the northern Catalan margin, dense shelf water cascading and severe coastal storms appear as the main transferring mechanisms of litter down-canyon. The three papers in our PhD Thesis provide a broader and more multidisciplinary vision of the hydrodynamic processes operating in submarine canyons, the resulting morphologies and the side effects of these processes in the present Anthropocene epoch, which is characterized by the long reach of the human footprint over the entire planet. Therefore, our PhD Thesis also conveys a warning message against the pervasive character of the anthropogenic impact on the marine environment. In this setting, knowing the functioning of submarine canyons becomes even more relevant as it goes much beyond than just Geology or Sedimentology.

The historical of the industrial and productive processes, which culminated with the neoliberal globalization (around forty years ago), lead the planet to an unprecedented level of devastation, a period during which, contradictorily, there was more talk about nature and the environmental challenge. As such, due to the tragic effects of the historical and social processes of the relation between the capitalist society and the environment – seen as a political, social, economic and cultural totality -, the following research has, as a general objective, to apprehend the mediations between the great and catastrophic environmental tendencies and the policy regarding solid waste in the city of Ponta Grossa/PR, given the current crisis regarding such waste in the city. The goal is to identify and comprehend the way in which this local policy does or does not incorporate the discourse for global rationality. The theoreticalmethodological nucleus of this research was built from the propositions of the worldsystems theory, which were developed through contributions of its main adepts, such as the American sociologist Immanuel Wallerstein; its proposer, Italian political economist Giovanni Arrighi; and the Brazilian thinkers Theotonio dos Santos and Carlos Walter Porto-Gonçalves, who, without abandoning the critical theory and the dialectic method of Marx and his classic categories such as mediation, contradiction, totality and history, promote the reconstruction of some of these categories and take up other new ones to form the central nucleus of their theoretical approach. For the treatment and analysis of the researched data, the qualitative method was utilized. As an instrument of research, the semi-structured interview was utilized, directed at the managers responsible for the policy regarding solid waste in the city of Ponta Grossa/PR. This research, however, inserts itself into a wider proposal within the environmental debate, discussing the rationalities that underlie the relations of the human being with nature, and understanding the environmental challenge not just as an economical and technological one, but, above all, as an ethical, social, and political challenge.<br>A presente pesquisa se inscreve no debate político que tem por tema o meio ambiente, a relação sociedade-natureza, os desafios socioambientais globais e a superação de uma contradição histórica entre economia capitalista e equilíbrio da vida humana e dos demais seres bióticos. O histórico dos processos industriais e produtivos, que culminou na globalização neoliberal (há cerca de 40 anos), conduziu o planeta a uma devastação sem precedentes em toda a história da humanidade, período em que, contraditoriamente, mais se falou da natureza e em que o próprio desafio ambiental se colocou como tal. Desta forma, em razão dos trágicos efeitos dos processos históricos e sociais da relação entre sociedade capitalista e natureza - vista como totalidade política, social, econômica e cultural - o presente trabalho tem por objetivo geral apreender na crise contemporânea dos resíduos sólidos no município de Ponta Grossa/PR as mediações existentes entre as grandes e catastróficas tendências ambientais globalizadas e a política municipal de resíduos sólidos, procurando identificar e compreender a forma com a qual esta política local incorpora ou não o discurso da racionalidade global. O núcleo teórico-metodológico desta pesquisa foi construído a partir das proposições da teoria sistema-mundo, desenvolvidas através das contribuições de seus principais adeptos, como o sociólogo estadunidense Immanuel Wallerstein, seu propositor, o economista político italiano Giovanni Arrighi, e os pensadores brasileiros Theotonio dos Santos e Carlos Walter Porto-Gonçalves, que, sem abandonarem a teoria crítica e o método dialético de Marx e suas clássicas categorias como mediação, contradição, totalidade e história, promovem a reconstrução de algumas destas categorias e se apropriam de outras novas para formar o núcleo central de sua abordagem teórica. Para o tratamento e análise dos dados pesquisados utilizou-se o método qualitativo. Como instrumento de pesquisa, utilizou-se a entrevista semi-estruturada dirigida aos gestores responsáveis pela política de resíduos sólidos no município de Ponta Grossa/PR. Este trabalho, portanto, insere-se numa proposta mais ampla dentro do debate ambiental, discutindo as racionalidades subjacentes às relações do homem com a natureza e compreendendo o desafio ambiental não apenas como um desafio econômico e tecnológico, mas, sobretudo, como um desafio ético, social e político.

Abstract:
Abstract Condensation in the exhaust gas system of an incinerator burning low activity radioactive wastes led to numerous corrosion developments and rapid failure of the discharge filters. The problem was traced to insufficient reheat of the exhaust gases following scrubbing. Rust particulate and moisture loaded the filters, leading to water accumulation, chloride cracking of the filter housings, and plugging and tearing of the filter media itself. To mitigate the problem, the exhaust gas temperature was increased, thermal insulation was installed on the ductwork, and the interiors of the ducts and new filter housings were lined with a protective coating.

Abstract:
Abstract Radioactive waste is stored in carbon-steel double-shell tanks at the Hanford site. The waste is transferred between the tanks and other assets using transfer lines that consist of carbon steel encased carrier and casing pipes. Recent inspection data of the transfer lines have shown extensive corrosion on both interior of the casing and exterior of the carrier pipes. The visual inspections have shown presence of extensive amount of corrosion products near the pipeline risers and beyond. It has been hypothesized that the corrosion is predominantly due to the high humidity conditions driven by raw water accumulation used during hydrotesting and by water accumulation due to the cold fingering effect. Drying of the transfer lines could lead to corrosion mitigation. Experimental studies were conducted to understand the effect of environmental conditions, especially, relative humidity and temperature, on the initiation of corrosion and mitigation of pre-existing pitting corrosion. The experimental conditions are selected based on the seasonal temperature changes, and relative humidity conditions ranging from 30 to 100 percent. The experimental data were used to determine the operation parameters that could mitigate the corrosion.

Abstract:
Every day, human activities generate large amounts of solid waste. To ensure the quality of the environment, waste must be further treated to prevent it from accumulation in landfills. In the case of materials that cannot be recycled or reused, such as municipal solid waste, burning in waste incineration plants to generate heat or electricity appears to be the appropriate solution of such waste disposal. However, combustion processes generate residues, such as bottom or fly ash, which must be stored. Fly ash generally contains heavy metals and other contaminants. If it is disposed in landfills, the contained substances may pollute the environment with dust, leach into the soil, and contaminate the groundwater. Therefore, it is important to find an alternative way to dispose fly ash, such as incorporation into building materials, which must provide sufficient and save immobilisation of heavy metals. The objective of the presented research was to utilize fly ash from waste incineration plant and diatomaceous earth in magnesia-based composites in the form of microfillers. The investigation focused on the determination of the material properties of the hardened composites with emphasis on the ability to immobilise heavy metals. Incorporation of fly ash and diatomaceous earth resulted in increased porosity and water absorption. The mechanical strength was also affected and reduced by the incorporation of both microfillers. On the other hand, the immobilisation test showed that the heavy metals contained in the fly ash were safely immobilised in the material and thus they are not able to be further released into the environment. In this way, hazardous waste can be safely treated and reused, and the amount of waste in landfills can be reduced.

Full text
Abstract:
Abstract Borescope visual inspections of buried pipe-in-pipe slurry transfer lines in the tank farms at the Hanford Site revealed corrosion and standing water in the annulus space between the encasement and primary pipes. Both the primary pipe and encasement were constructed from schedule 40 seamless carbon steel (ASTM A106 Grade B). Three encasement sections were cut from the transfer lines, and corrosion analysis was performed to assess the level and possible causes of encasement interior surface corrosion. The solid debris/material collected from the pipe interior surface was predominantly corrosion products, but it also contained a small amount of soluble fluoride, chloride, nitrate, acetate, and sulfate that could have facilitated the corrosion process and increased the corrosivity of the water. One of the three encasement sections had the deepest and most severe pitting corrosion induced by the standing water and the presence of O2 for possibly over a decade. The maximum pit depth was about 23% of the wall thickness on the interior surface. Residual water used for hydrotesting the lines may have remained in the annulus since the beginning of transfer line service, initiating corrosion. Water and corrosion product accumulation at the later stage of corrosion and the presence of bacteria at the bottom of the transfer line exacerbated corrosion. The other two of the three encasement sections had less corrosion.

Abstract:
The objective of our research is to screen and search for suitable plant species for phytoremediation of mercury-contaminated soil. Currently our effort is specifically focused on mercury removal from the U.S. Department of Energy (DOE) sites, where mercury contamination is a major concern. In order to cost effectively implement mercury remediation efforts, it is necessary now to obtain an improved understanding of biological means of removing mercury and mercury compounds. Phytoremediation is a technology that uses various plants to degrade, extract, contain, or immobilize contaminants from soil and water. In particular, phytoextraction is the uptake of contaminants by plant roots and translocation within the plants to shoots or leaves. Contaminants are generally removed by harvesting the plants. We have investigated phytoextraction of mercury from contaminated soil by using some of the known metal-accumulating plants since no natural plant species with mercury hyperaccumulating properties has yet been identified. Different natural plant species have been studied for mercury uptake, accumulation, toxicity and overall mercury removal efficiency. Various mercury compounds, such as HgS, HgCl2, and Hg(NO3)2, were used as contaminant sources. Different types of soil were examined and chosen for phytoremediation experiments. We have applied microscopy and diffuse reflectance spectrometry as well as conventional analytical chemistry to monitor the phytoremediation processes of mercury uptake, translocation and accumulation, and the physiological impact of mercury contaminants on selected plant species. Our results indicate that certain plant species, such as beard grass (Polypogon monospeliensis), accumulated a very limited amount of mercury in the shoots (&lt;65 mg/kg), even though root mercury accumulation is significant (maximum 2298 mg/kg). Consequently, this plant species may not be suitable for mercury phytoremediation. Other plant species, such as Indian mustard (Brassica juncea), a well-studied metal accumulator, exhibited severe chlorosis symptoms during some experiments. Among all the plant species studied, Chinese brake fern (Pteris vittata) accumulated significant amount of mercury in both roots and shoots and hence may be considered as a potential candidate for mercury phytoextraction. During one experiment, Chinese brake ferns accumulated 540 mg/kg and 1469 mg/kg in shoots after 18 days of growing in soils treated with 500 parts-per-million (ppm) and 1000 ppm HgCl2 powder, respectively; no visual stress symptoms were observed. We also studied mercury phytoremediation using aged soils that contained HgS, HgCl2, or Hg(NO3)2. We have found that up to hundreds of ppm mercury can be accumulated in the roots of Indian mustard plants grown with soil contaminated by mercury sulfide; HgS is assumed to be the most stable and also the predominant mercury form in floodplain soils. We have also started to investigate different mercury uptake mechanisms, such as root uptake of soil contaminant and foliar mercury accumulation from ambient air. We have observed mercury translocation from roots to shoot for Chinese fern and two Indian mustard varieties.

Full text
Abstract:
During storage, spent fuel and other waste forms accumulate alpha-decay damage (and He). The dose rates and the temperatures experienced during storage are lower than during in-pile operation: however, the duration of the storage is much longer (of the order of up to a few hundred years if extended interim storage concepts are considered); if final disposal in the repository is considered, the time interval in which radiation damage accumulates is open-ended. In order to simulate within timeframes suitable for laboratory experiments long-term accumulation of alpha-decay damage, the so-called alpha-doped materials can be used, i.e. materials loaded with short-lived alpha-emitters (like e.g. Pu-238, U-233, etc.). The question is often posed if the accelerated accumulation of decay damage and He obtained using alpha-doped materials does cause some artefact related to the rate of accumulation rather than by the integrated dose. This work presents evidence that, at least within the range of alpha-activities considered, there is no dose rate effect. By comparing property evolution as a function of accumulated dpa for alpha-doped materials with activities of ∼1010 and ∼108 Bq/g, respectively, the same trends and levels of alteration are observed. In particular, macroscopic properties like hardness (measured by Vickers indentation) or swelling (evolution of lattice parameter derived from XRD), and microstructural formation and accumulation of defects in the lattice of the alpha-doped material are investigated, showing a remarkable similarity of behaviour vs. dpa independently not only from the dose rate, but also from the composition (namely, Pu and U are considered).

Abstract:
The need for automobiles is increasing each day and the usage of these vehicles also increased the waste production. Rubber tyre is the one of the main wastes generated when it comes to automobiles. Since rubber is an elastomeric material, it is hard to recycle. So, the accumulating tyre waste is a matter of concern and it leads to various ecological properties. Incorporating a percentage of shredded tyre in concrete to coarse aggregates can reduce the waste accumulation. Since shredded tyre is a light weight material its addition in concrete can reduce the weight of concrete. This study compares the strength characteristics of normal concrete with lighter-weight concrete in which tyre trash is used in place of the coarse aggregate.

Abstract:
In the proposed work, an optimization model of transportation of municipal solid waste (MSW) of the urban agglomeration carried out by the waste processing and disposal complex is formulated and investigated. The complex includes waste processing plants, landfills and transport enterprises. Optimization here means minimizing the costs (fuel, time, finance) for the transportation of MSW from their accumulation sites (garbage sites) to processing points (waste processing plants) and landfills (landfills).
