Um dos problemas ambientais com que nos deparamos está ligado à gestão dos resíduos sólidos oriundos das atividades humanas, seja na forma de disposição, no volume na geração, e na ineficiência na reutilização e reciclagem destes. A gestão integrada de resíduos sólidos pauta-se como importante instrumento para que se caminhe em direção a um modelo de sociedade menos agressivo com o meio ambiente. Para buscar esta forma de gestão, no Brasil, a Lei nº 12.305/2010 institui a Política Nacional de Resíduos Sólidos. Partindo deste contexto, tem-se como foco os Planos Municipais de Gestão Integrada de Resíduos Sólidos - PMGIRS. O trabalho tem por objetivo avaliar a situação dos processos de elaboração dos PMGIRS nos municípios da Bacia Hidrográfica Tietê-Jacaré (UGRHI-13). É apresentada uma proposta de avaliação quantitativa e qualitativa dos PMGIRS, visando o cumprimento destes perante à PNRS. Chegou-se em um resultado de que 62% dos municípios afirmam possuir PMGIRS; 9% não possuem; e 29% estão em processo de elaboração. A UGRHI-13 conta com 34 municípios, destes, vinte e um (21) municípios afirmam ter PMGIRS, porém após a avaliação destes, verificou-se que três efetivamente não o tem. Logo, o número de municípios que possuem o PMGIRS é dezoito (18), ou seja, 53% dos municípios da UGRHI-13. Consequentemente, 47% dos municípios não possuem o Plano. Nove (9) cumprem menos que 75% dos requisitos mínimos da PNRS. Apenas dois (2) dos dezoito (18) municípios que efetivamente possuem PMGIRS cumprem em 100% os requisitos mínimos. O cenário positivo para a gestão integrada de resíduos sólidos municipais vem evoluindo, porém ainda enfrenta uma série de obstáculos relacionados à falta e inconsistência de informação e falta de capacitação técnica dos gestores públicos. / One of the environmental problems we face is related to the management of solid waste from human activities, whether in the form of disposal, volume in generation, and inefficiency in their reuse and recycling. Integrated solid waste management is an important instrument for moving towards a less aggressive model of society with the environment. In order to seek this form of management, in Brazil, Law nº. 12,305/2010 establishes the National Policy on Solid Waste. Starting from this context, we focus on the Municipal Plans of Integrated Management of Solid Waste - PMGIRS. The objective of this study is to evaluate the situation of the PMGIRS elaboration processes in the municipalities of the Tietê-Jacaré Hydrographic Basin (UGRHI-13). A proposal for the quantitative and qualitative evaluation of the PMGIRS is presented, with a view to their compliance with the PNRS. It was found that 62% of municipalities claim PMGIRS; 9% do not have; And 29% are in the process of being drawn up. The UGRHI-13 counts with 34 municipalities, of which twenty one (21) municipalities claim to have PMGIRS, but after evaluating them, it was verified that three do not have it. Therefore, the number of municipalities that have the PMGIRS is eighteen (18), or 53% of the municipalities of the UGRHI-13. Consequently, 47% of municipalities do not have the Plan. Nine (9) meet less than 75% of the minimum PNRS requirements. Only two (2) of the eighteen (18) municipalities that effectively have PMGIRS meet the minimum requirements at 100%. The positive scenario for the integrated management of solid municipal waste has been evolving, but it still faces a series of obstacles related to lack and inconsistency of information and lack of technical capacity of public managers.

In Sweden, there are limits to how much leachable substances waste must contain in order to be deposited as hazardous waste. Fly ash from waste incineration often end up over the limit, mainly due to the chloride content. Fly ash is therefore often deposited abroad. The purpose of this study was to investigate the possibility to handle fly ash locally. To clarify how the law is applied, environmental reports and permit documents from ten waste sites with permission to deposit fly ash were studied. In addition, a literature study was made to review the state of knowledge regarding the treatments of fly ash. The treatment methods are numerous, but are at different levels of commerciality. Among the treatments available there are both physical, chemical, biological, electrical and thermal variants. Many of the treatments (except for carbonation and microbial bioleaching) results in chloride levels below the limits. Several are however unrealistically expensive or generate wastewater with high levels of chloride that would need further treatment. Three plants out of the ten holding permits to deposit fly ash, have exemptions from the limit for chlorides. It's however difficult to see a common reasoning for allowing exemptions. In several cases there are sensitive receiving waters downstream from the landfill. One reason to be dispensed despite this sensitivity, may be the guidance that EPA issued. It is not formulated any specific concerns relating to chlorides. One handles therefore often high levels of chloride in the leachate as a dilution problem, not a leaching problem. / I Sverige finns det gränsvärden för hur mycket utlakningsbara ämnen avfall får innehålla för att kunna deponeras som farligt avfall. Flygaska från avfallsförbränning hamnar ofta över gränsen för vad som får deponeras, främst p.g.a. kloridinnehållet, och askan deponeras därför bl.a. i Norge och Tyskland. Syftet med denna studie var att utreda möjligheten att hantera flygaska lokalt. För att klargöra hur lagstiftningen tillämpas har miljörapporter och tillståndsbeslut från tio avfallsanläggningar med tillstånd att deponera flygaska studerats. Dessutom har en litteraturstudie gjorts av kunskapsläget när det gäller behandling av flygaska för att motverka lakning av klorider. Behandlingsmetoderna är många, men har kommit olika långt i att anses som kommersiella. Bland behandlingarna finns både fysiska, kemiska, biologiska, elektriska och termiska varianter. Många av behandlingarna (med undantag för karbonatisering och mikrobiell bioutlakning) gör att gränsvärden för utlakning av klorider klaras. Många av behandlingarna är dock orealistiskt dyra eller genererar avloppsvatten med höga kloridhalter. Av de tio anläggningar som innehar tillstånd till att deponera flygaska, så har tre även dispens för gränsvärdet för klorider. Utifrån den information som finns i tillståndsbesluten är det mycket svårt att se ett mönster vad gäller bedömningen av de enskilda fallen. I flera fall finns känsliga recipienter nedströms deponin. En anledning till att dispens ges trots denna känslighet kan vara den vägledning som Naturvårdsverket gett ut. Där formuleras inte någon specifik problematik kring klorider, utan andra ämnen är i fokus. Man behandlar därför ofta höga kloridhalter i lakvatten som ett utspädningsproblem, istället för ett utlakningsproblem.

Objective knowledge about quantity, composition and physicochemical characteristics of municipal solid waste (MSW) in the Czech Republic will form the basis for decision- making when considering processing facilities or regional waste management systems. As the country continues to streamline its legislation to the European Union's solid waste mandates, the results of these studies were employed by the Czech Ministry of Environment to optimise the national waste management strategy. This doctoral thesis focuses on the composition of MSW, primarily the mixed MSW from three types of households in the Czech Republic (urban, mixed and rural) differentiated by their heating methods and possibility of waste disposal. The respective experimental work and data-collection took place in years 2008 and 2009. Methodology used in the analyses is based on the sieve analysis of mixed MSW within predetermined grain size fraction and on the final manual sorting of the waste by material categories. The physicochemical characteristics were measured according to the standard analysis methods. The composition of mixed MSW in urban and mixed households are similar. Some of the biggest differences were found in the quantities of certain subsample categories, especially fine fraction (matter smaller than 8 mm), between...

Proper consumer attitude towards textile products and optimal post-consumer waste management of textile waste is connected with many benefits. Despite this fact, little research has been conducted on these topics. Textile waste represented mainly by donated textile from households and its material flow in waste streams mirrors the behaviour of our consumer society as well as new technologies in textile and fashion industry. More information about consumer attitude and behaviour toward textile and textile waste is needed to provide suitable waste management processes according to the hierarchy of waste management, such as re-use and energy recovery, and to ensure sustainable development and minimal impact on the worlds wellbeing. This study takes into account not only waste management of textile waste, but also tries to understand all textile issues in a wider perspective. Particularly fashion industry is connected with many negative ethical aspects (e.g. sweatshops), and many environmental issues are connected with overproduction of lower-quality textile products. Proper handling of post-consumer textile products is only one of the product life cycle stages to be solved. The main goal of this study is to discuss the results of a consumer attitude and behaviour questionnaire toward textile and textile waste from households in the Czech Republic. The study also includes partial hypotheses and an analysis of interest groups as other possible sources of information to form proper textile waste management policy tools and strategies.

Subtitle D of the Resource Conservation and Recovery Act (RCRA) requires a post closure period of 30 years for non hazardous wastes in landfills. Post closure care (PCC) activities under Subtitle D include leachate collection and treatment, groundwater monitoring, inspection and maintenance of the final cover, and monitoring to ensure that landfill gas does not migrate off site or into on site buildings. The decision to reduce PCC duration requires exploration of a performance based methodology to Florida landfills. PCC should be based on whether the landfill is a threat to human health or the environment. Historically no risk based procedure has been available to establish an early end to PCC. Landfill stability depends on a number of factors that include variables that relate to operations both before and after the closure of a landfill cell. Therefore, PCC decisions should be based on location specific factors, operational factors, design factors, post closure performance, end use, and risk analysis. The question of appropriate PCC period for Florida’s landfills requires in depth case studies focusing on the analysis of the performance data from closed landfills in Florida. Based on data availability, Davie Landfill was identified as case study site for a case by case analysis of landfill stability. The performance based PCC decision system developed by Geosyntec Consultants was used for the assessment of site conditions to project PCC needs. The available data for leachate and gas quantity and quality, ground water quality, and cap conditions were evaluated. The quality and quantity data for leachate and gas were analyzed to project the levels of pollutants in leachate and groundwater in reference to maximum contaminant level (MCL). In addition, the projected amount of gas quantity was estimated. A set of contaminants (including metals and organics) were identified as contaminants detected in groundwater for health risk assessment. These contaminants were selected based on their detection frequency and levels in leachate and ground water; and their historical and projected trends. During the evaluations a range of discrepancies and problems that related to the collection and documentation were encountered and possible solutions made. Based on the results of PCC performance integrated with risk assessment, projection of future PCC monitoring needs and sustainable waste management options were identified. According to these results, landfill gas monitoring can be terminated, leachate and groundwater monitoring for parameters above MCL and surveying of the cap integrity should be continued. The parameters which cause longer monitoring periods can be eliminated for the future sustainable landfills. As a conclusion, 30 year PCC period can be reduced for some of the landfill components based on their potential impacts to human health and environment (HH&E).

Programa de Pós-Graduação em Energia, Santo André, 2016. / No ano 2010, o Congresso Nacional do Brasil aprovou a Política Nacional de Resíduos Sólidos (PNRS) com o objetivo de buscar soluções aos problemas causados pela geração de resíduos, que vêm afetando a qualidade de vida da população. Além disso, a PNRS propõe uma gestão eficaz que inclui desde a redução da geração dos resíduos até sua disposição final adequada, aprovando a possibilidade de recuperação de energia a partir dos mesmos. Alguns países incluíram a Conversão de Resíduos em Energia do inglês Waste to Energy-WTE, nos seus planos nacionais de gestão de resíduos como tratamento mediante o processo de combustão in natura. O objetivo deste trabalho foi caracterizar as frações combustíveis (matéria orgânica, resíduos sanitários, plásticos, papel/papelão/tetra pak e têxteis) dos Resíduos Sólidos Urbanos (RSU) úmidos gerados no município de Santo André localizado no estado de São Paulo com vistas ao seu aproveitamento energético. As frações combustíveis foram caracterizadas tendo em conta sua composição gravimétrica, analisando suas propriedades densidade a granel, umidade, análise imediata e poder calorífico avaliadas na estação de primavera-verão de 2015, visando sua conversão em energia mediante o processo de combustão in natura. Com o objetivo de obter amostras representativas foi utilizada a norma MODECOMTM para o cálculo do número de amostras para a caracterização dos RSU. Para a determinação de suas propriedades foram usadas as normas ASTM para combustível derivado de resíduos (CDR). De acordo com os resultados obtidos os RSU úmidos gerados no município têm umidade de 51,5%, poder calorífico inferior (PCI) de 7,53 MJ/kg e capacidade de geração de energia elétrica de 565 kWh por tonelada de resíduo incinerado com eficiência de conversão de 27%, características favoráveis para sua conversão em energia mediante sua combustão in natura, oferecendo assim uma opção de tratamento, ao invés da sua disposição no aterro sanitário. / In 2010, Brazil approved the National Politic of Municipal Solid Waste (NPSW) in order to seek for solutions to the problems caused by the generation of waste, that has been affecting the population's quality of life. The NPSW also proposes an efficient management including the reduction of waste generation and the correct final disposition, by evaluating its energy recovery. Currently some countries include in their national management plans, the conversion of Waste to Energy (WTE) using the combustion process. The objective of this work was to evaluate the energy potential of fraction combustible (organic matter, sanitary waste, plastics, paper/cardboard/tetra pak and textiles) of the Municipal Solid Waste (MSW) generated by Santo André, a town located in the state of Sao Paulo. The fraction combustible was characterized taking into account their composition and analyzing their physical (bulk density), chemical (proximate analysis) and thermal (calorific value) properties, evaluated in the spring and summer season, aiming its conversion to energy using combustion process. With the purpose of having representative samples, MODECOMTM methodology has used to calculate the samples number in the MSW characterization. To determinate the physical, chemical and thermal properties in the laboratory, were used the ASTM standards for Refuse Derived Fuel (RDF). According to the results obtained, the MSW generated in the municipality the humidity is 51,5%, lower heating value (LHV) 7,53 MJ/kg and generation capacity in electricity 565 kWh tonne of waste incinerated a conversion efficiency of 27% , showed favorable characteristics to their conversion to energy using mass burning, providing a treatment option, instead of its disposal at the landfill.

An investigation of the variability of engineering properties of municipal solid waste as a function of placement conditions was conducted. Limited data have been reported for the engineering properties of municipal solid waste (MSW) as a function of placement conditions. Wastes have high variability of engineering properties due to heterogeneity in composition and component size; influence from time based effects; and presence of compressible solids. Control of moisture content of MSW at the time of waste placement provides opportunity for increased capacity at a given landfill site due to higher compacted unit weight as well as for control of other geotechnical properties. A laboratory experimental test program was conducted on manufactured municipal solid waste (MMSW) that was representative of waste stream in the United States. Large scale test equipment was used to minimize the effects of scaling on results. The experimental program included compaction, compressibility, hydraulic conductivity, and shear strength testing over moisture contents ranging from 11% to 110%. Baseline compaction curves were developed for different compactive efforts. Similar to soils, the MMSW had bell shaped compaction curves that peaked at a maximum dry unit weight and associated optimum moisture content. The compaction curve generated at modified compactive effort had a maximum dry unit weight of 5.1 kN/m3 and optimum moisture content of 66%. Four times modified compactive effort testing resulted in a maximum dry unit weight of 5.9 kN/m3 and corresponding optimum moisture content of 56%. The compaction curve generated for four times modified compactive effort was used as a baseline for subsequent testing. Compression index was calculated from the strain-log stress curves for total stress conditions and is referred to as apparent compression index. Apparent compression index decreased from 1.1 to 0.34 with increasing moisture content. Secant modulus of elasticity was calculated between 1% and 25% strain and ranged from approximately 200 kPa to 4,800 kPa over the range of tested moisture contents. Tangent modulus ranged from 400 kPa to 6,200 kPa between 1% and 25% strain. Both the secant and tangent modulus peaked between 30% and 56% moisture content. Wet of optimum, the moduli of elasticity decreased with increasing moisture content. The hydraulic conductivity was measured under constant head at a hydraulic gradient of 1 and decreased asymptotically from approximately 1.3x10-2 cm/s to 8x10-5 cm/s as the moisture content was increased to optimum. The hydraulic conductivity of the MMSW increased slightly wet of optimum. The internal angle of friction of the MMSW was measured at 15% shear strain and decreased from approximately 40° to 30° with increasing moisture content. Test results demonstrated that both the molding moisture content and dry unit weight have significant impact on the MMSW geotechnical properties, although it appears that molding moisture content ultimately controls the behavior. Based on the results of the tests it was speculated that, similar to clay soils, increases in moisture content allowed for breakdown of the fabric and physical rearrangement of waste components which in turn controlled geotechnical behavior. Overall trends were comparable for MMSW and soil and included: increased dry density and increased stiffness to optimum moisture content; decreased hydraulic conductivity with increased compaction moisture content; and decreased shear strength with increased compaction moisture content. The results of the test program have environmental and economic implications for design and operation of landfills as well as post closure use.

Following diploma thesis deals with waste-based renewable energy production. Waste is a very heterogeneous mixture consisting of various materials with different origin. This can be either fossil or biogenic. The very substances with biogenic origin are considered renewable energy source with financial support from state. Therefore is nowadays tendency to develop a method, which can determine the biogenic waste ratio. The method, aside possible cheapest price and simplicity, should be also reliable and easy reproducible due to its usage. At the beginning, thesis focuses on the waste-to-energy facilities. Important part deals with legislative side of this topic. The reasons, why Czech Republic is behind with thermal waste treating are stated as well as Czech Republic’s obligations to European Union in the field of biodegradable municipal solid waste. Main part of thesis deals with different methods to determine biogenic waste ratio in municipal solid waste. Step by step are introduces 4 known methods, where especially sorting, balance and 14C methods are described closely. By each method are stated its major benefits and handicaps in case of using. Finally, the computational model, which is based upon balance methods equations, is introduced following with feasibility study of balance method for local conditions. The very end of the thesis brings comparison of each method results, general summary, where are results of this thesis stated and possible trends for future in this area of expertise, as well.
