Повний текст джерелаLa tesis aborda el metabolismo socioeconómico de todas las Comunidades Autónomas (CCAA) españolas entre 1996 y 2010, adaptando las metodologías armonizadas a nivel estatal para su aplicación regional. Siendo escasos los antecedentes de estos cálculos, se plantean una serie de retos metodológicos y conceptuales que es necesario abordar para llevar a cabo la contabilidad de flujos materiales a escalas regionales. Se aborda en primer lugar la elaboración de una base de datos de flujos materiales y el cálculo de los principales indicadores de extracción, comercio interregional e internacional, consumo y productividad en términos biofísicos en el periodo estudiado, donde el boom inmobiliario y la posterior crisis provocan dinámicas muy marcadas de incremento de la extracción de recursos naturales y de importaciones internacionales. Además, se cuantifica el volumen del comercio biofísico entre CCAA desvelando la relevancia del comercio de productos de construcción durante los años de crecimiento económico y una gran disparidad en los valores de los indicadores principales a lo largo de las CCAA. A continuación, se realiza un estudio más detallado de las dinámicas del comercio por tipos de material y analizando el mercado internacional e interregional por separado. Se encuentra una dependencia absoluta de todas las CCAA del mercado exterior para metales y combustibles fósiles y se modelizan los principales roles comerciales de las CCAA en el mercado internacional e interregional para la biomasa y los minerales no metálicos. A pesar de algunas limitaciones metodológicas, se consigue realizar un perfil de la CCAA españolas en cuanto a su rol en el desplazamiento de cargas ambientales mediante el comercio y se cuantifica el peso de los minerales de construcción en estos fenómenos. Destaca el rol de Madrid como región altamente dependiente para todos los materiales y por tanto responsable de una fuerte carga ambiental desplazada a otras CCAA y otros países. Finalmente, se realiza un análisis de la gestión de residuos municipales de las CCAA españolas en cuanto al cumplimiento de los objetivos de reciclaje de la Unión Europea. Se encuentra, al igual que en el caso de la extracción, el consumo y el comercio, perfiles muy diferentes que desembocan en resultados dispares en cuanto a la gestión de residuos municipales. Se identifica la distancia de CCAA a los objetivos europeos y se plantean los mínimos que deberán cumplir en cuanto apolíticas básicas de gestión de residuos para conseguir el objetivo de reciclaje planteado. En todo caso, todas las CCAA españolas estaban lejos de cumplir con la normativa europea, y en particular se incide sobre la necesidad de una política más eficaz de recogida de biorresiduos, una coordinación de las herramientas fiscales y en particular de los impuestos al vertido, y una disparidad en cuanto a tecnologías que hace imprescindible su normalización y la diseminación de las mejores tecnologías disponibles para el conjunto del territorio. En conjunto se concluye que el metabolismo de las CCAA españolas, tanto por el lado de las entradas de materiales como por el lado de la gestión de residuos, presenta disparidades que apuntan a una polarización de las cargas ambientales derivadas del proceso económico. Además, se concluye que la falta de datos sobre variables básicas del metabolismo socioeconómico, con importancia económica y ambiental, sigue siendo un lastre para la investigación orientad a informar a las políticas públicas.
The thesis addresses the socioeconomic metabolism of the whole of the Spanish Autonomous Communities (AC) between 1996 and 2010, adapting the harmonized methodologies at the national level for their subnational application. Since the background of these calculations is scarce, a series of methodological and conceptual challenges are addressed to carry out material flow accounting at subnational scales. First, the elaboration of a database and the calculation of the main indicators of extraction, interregional and international trade, consumption and productivity in biophysical terms is addressed in the period studied. During this period, the housing bubble and the subsequent crisis caused very marked patterns of increased extraction of natural resources and international imports. In addition, the volume of biophysical trade between AC is quantified, revealing the relevance of trade of construction products during years of economic growth and a great disparity in the values of the main indicators across AC. Next, a more detailed study of trade patterns by types of material and analysing the international and interregional and international markets separately is developed. An absolute dependence on foreign metals and fossil fuels is identified and the main commercial roles of the AC in the international and interregional market for biomass and non-metallic minerals are modelled. Despite some methodological limitations, the commercial profile of the AC is calculated and their environmental burden shifting through trade including construction minerals is quantified. Madrid stands out as a highly dependent region for all materials and therefore responsible for a strong environmental burden shifting towards other AC and other countries. Finally, an analysis of the municipal waste management of the AC regarding the fulfilment of the European Union’s recycling targets is carried out. It is found that, as in the case of extraction, consumption and trade, very different management profiles exist, which leads to differing results in terms of municipal waste management. The distance to the target of the AC is identified and the minimum policies required for accomplishing the target are identified. In any case, all AC were far from complying with the European recycling targets. Some measures required to close this gap are a more efficient policy for the separate collection of bio-waste; a coordination of fiscal tools, particularly landfill taxes; and the standardization and the dissemination of the best available technologies. Overall, it is concluded that the socioeconomic metabolism of the AC, both regarding the input side and waste management, presents disparities that points to a polarisation of the environmental burdens derived from the economic process. In addition, it is concluded that the lack of data on basic variables of economic and environmental relevance jeopardises research aimed at informing public policies.

Повний текст джерелаDen begränsade mängden naturresurser som existerar på vår planet har diskuterats under det senaste decenniet aktivt. Återvinning av material blir allt viktigare i dagens samhälle och vi kan se en trend var utvecklingen strävar efter beslut som har rötterna i cirkulär ekonomiskaprinciper. Resultatet av diskussionerna har blivit höga måtsättningar för medlemsländerna i Europeiska Unionen gällande återvinning var målet är att uppnå en återvinningsgrad på 70% innan 2020 för bygg- och rivavfall. Studien använder materialflödes analys (MFA) som metod för att kartlägga och kvantifiera flödnena av bygg- och rivavfall. Materialflödes analysen använder data från årsrapporter och statistik som blivit tillgängligt av HSY (statligt ägt bolag) samt av intervjuerna som utfördes på fältet. För att kvantifiera flödena på basis av den konceptuella modellen avnändes mjukvaran STAN. Avhandlingen strävar efter att ta första steget för att kartlägga materialflöden av bygg- och rivavfall i huvudstadsregionen (Helsingfors). Målet är att skapa en modell som kan användas som botten i framtida undersökningar och att kvantifiera modellen med existerande data för att se ifall målsättningarna stadgade av Europeiska Unionen kommer att uppnås innan 2020. Studien utfördes på cirkulär ekonomi stationen Ekomo för att kunna göra upp modeller för den privata sektorn och den kommunalla sektorn eftersom båda är verksamma på Ekomo. Resultaten av anvhandlingen var följande: Den privata sektorn och staten uppnår en återvinningsgrad på över 90% vilket är väl över stadgan satt av den Europeiska Unionen under året 2017 med en stadig utveckling från året innan med en väldigt liten andel som placeras på soptipp. Resultaten visar en stark utveckling av intresse från hushåll och företag för återvinning eftersom antalet kunder och lastbilar som besökt stationen ökat starkt under de senaste fem åren. Även om målsättningarna inom återvinning är uppnådda finns det ärenden som måste behandlas för att försäkra en fortsatt positiv utveckling. Den privata sektorn upplever att begränsade möjligheter för återanvänd krossbetong minskar efterfrågan på produkten, vilket gör den finansiellt svår att integrera i deras försälning. Buller- och miljötillstånd tvingar för tillfället bolagen att transportera bygg- och rivmaterialet utanför rivmålet, t.ex till Ekomo, för att krossas vilket ytterligare skapar finansiella problem för den privata sektorn. Lösningar för att göra återvinning av riv- och byggnadsmaterial för den privata sektorn lukrativare behövs för att inspirera flera organisationer att ansluta sig till arbete mot ett mera cirkulärt samhälle. Monitorering och snabbare anpassningsförmåga för internationella standarder krävs för att kunna utnyttja cirkulär ekonomiska initiativ på bästa möjliga sättet. För att komplettera avhandlingen skulle det vara intressant att se resultaten av en livcykelanalys (LCA) gällande samma flöden för att identifiera miljörelaterade problem och för att optimera flöden.

Повний текст джерелаFör decennier sedan krävde 1 ton stål 80 kg eldfast material. Medan scenariot har förändrats helt genom åren. Idag behöver 1 ton stål cirka 11 kg eldfast material beroende på stålverk. Eldfasta produkter är vana vid högtemperaturprocesser, till exempel produktion av stål, glas etc. Mängden förbrukade eldfasta produkter har också ökat med ökad efterfrågan på dess produktion. För tillverkning av eldfasta produkter finns det en enorm användning av jungfruliga råvaror men med prisökningen och minskade råvarukällor blir det svårt att fortsätta på det sättet i framtiden. Medan miljöproblemen inom stålindustrin ökar i snabb skala, såsom global miljöförorening, bevarande av naturresurser och den viktigaste ökningen av kostnaderna för deponering. Därför är det nödvändigt att i framtiden uppnå noll slöseri och korrekt användning av material från förbrukade eldfasta anläggningar av ekonomiska och miljömässiga skäl. Detta projektarbete fokuserar på att samla in information om eldfast avfallshantering för stöd till mer hållbar svensk stålindustri. Projektet genomförs i samarbete med KTH Royal Institute of Technology och den svenska stålproducentföreningen Jernkontoret. Detta arbete fokuserar på en undersökning av välkända svenska stålföretag Sandvik Materials Technology (SMT) AB och Höganäs AB. Det vetenskapliga arbetet koncentrerar sig på undersökningen av blandat avfall av MgO-C-tegel, samlat från Mireco AB, upp till en kornstorlek på 20 mm. Tre prover med olika kompositioner och olika kornstorlekar samlades från återvinningsstället och bearbetades för kolreduktion. På flera stigar uppnåddes den maximala kolelimineringen vid en temperatur högre än 800 ° C med en hålltid längre än 5 timmar. Böterna genomgick mekanisk pressning av 40 MPa för att bilda pellets med 16 mm och 32 mm i diameter. De viktigaste spårade elementen i MgO, SiO2, CaO, Al2O3 och Fe2O3 kan användas för applikationer inom jordbruksindustrin. MgO finns i den maximala kvantiteten (70-80%). Genom möjlig utvinning av MgO från böterna kan användas i degelindustrin, byggindustrin och stålindustrin för slaggbildning. MgO i form av tillskott för magnesiumbristjord eller kalciummagnesiumoxid för neutralisering av jordens pH genom balansering av surheten kan användas. Böternas kompatibilitet kan vara till hjälp för att lösa transportproblem och gynna praktiska tillägg till processer. Sammantaget ger detta arbete en hög potential för att använda sådana eldfasta avfallsmaterial för applikationer förutomdeponering med tonvikt på jordbruk

Data compiled on these aspects were analyzed statistically via ANOVA and regression analyses. The results showed that waste percentage values displayed differences among materials. Design-related aspects, skill level and attitude of labor, incorrect calculation of material quantities, contractual clauses and material defects were the most effective reasons for waste within the projects analyzed.

Повний текст джерелаConcern for environmental degradation has been a motivating factor in the efforts to reuse or recycle construction and demolition waste. The intention is not only to reduce environmental desecration, but also to recycle the construction and demolition waste into potential building materials to be reused elsewhere. This study investigated the supply and demand of recycled construction materials in the Western Cape, and aimed to determine the perception held by important stakeholders about these materials. A qualitative analysis of the case study results revealed that poor waste management plans implemented on construction and demolition sites have affected the quality, supply and price of recycled materials. In addition to this it was also revealed that the negative perceptions regarding recycled materials were the major barriers to creating an established secondary market. Inadequate knowledge and experience were major contributors to resistance to change of perceptions. A case study was conducted on Malans Quarries Recyclers in order to determine the supply of raw materials (construction and demolition waste) reaching the recycling plant; the supply of recycled materials to the end user (consumer); and the recycling process that takes place. A sample of fifteen respondents from a variety of large, medium and small construction contractors, as well as consultants and civil engineering companies, completed a questionnaire to determine the demand for and perceptions about these materials. The qualitative analysis of the results of the questionnaires showed that the majority of respondents still preferred to use primary materials over recycled materials. However, it appears that the gap between respondents who prefer to use primary materials, and those who utilize recycled materials, has narrowed in comparison to results obtained in previous studies. It seems that there may be more usage of recycled materials in the future. The results also revealed that tax cuts, could be a good economic incentive to encourage the use of recycled material. The questionnaire results also revealed that the majority of the respondents believed that landfill taxes where not effective in discouraging the illegal dumping of waste, and that the lack advertisements, and difficulties in obtaining recycled materials played a crucial role in the under-use of recycled materials.

Повний текст джерелаSCA Obbola is a papermill that is investing in the future and is expanding its production. The project is called Expansion Obbola and they plan to increase their factory's capacity from 450,000 tonnes kraftliner to 725,000 tonnes. Peab is the contractor for the project, it started in 2018 and is expected to be completed by the year 2023. In collaboration with Peab, a report has been carried out on the Expansion Obbola project to find out how they work to minimize material waste. The report will also look into the current way of dealing with material waste and if the opportunity exists to reduce the amount of material waste even more. The purpose of the report is to get a clearer picture of the material waste on the project Expansion Obbola, to further enable and expand Peab's work with material waste in an efficient, economical and environmentally friendly way. The report also aims to contribute to Peab's future work with material waste in a positive way. During the production of a new building, it is estimated that 30-40% of total cost consists of material costs, which means that if the amount of material waste can be limited, it can contribute to a more sustainable, economical and environmentally friendly way of building. This report resulted in that the situation in project Expansion Obbola is consisting of some difficulties and that it significantly complicates the possibility of reducing the material waste. Pressured time schedule, lack of space and limited guidelines on how to handle material waste are the main difficulties that the project poses but after the completion of this report, it is still considered that there are plenty of development areas for the project regarding material waste. Some of the presented proposals on how to work to reduce the amount of material waste are: Changing the day and time for revision of drawings, increase the cooperation between supervisors, change the wood for casting to a lower quality to spare the environment and expand the collaboration with the designers. The Expansion Obbola project is therefore considered, despite difficult conditions, to have good opportunities to improve its work with material waste and potentially be able to reduce the amount of material that is thrown away unnecessarily.

Повний текст джерелаTyre waste from end-of-life tyres (ELTs), sometimes erroneously defined as a type of waste, in fact represents a renewable energy resource that is highly competitive as replacement fuel to coal in the form of tyre-derived fuel (TDF) or useable as rubber crumb in other products. In this research study, the main utilisation options considered were based on rubber crumbing through ambient and cryogenic processing. Pyrolysis, the so-called ‘holy grail’ of tyre technologies, rubberised asphalt products, TDF options and various other product options from tyre crumb as basis were considered. Although pyrolysis technology is highly commendable and environmentally friendly, it is still a process with too many variants and presents an unstable economic model that is not attractive to entrepreneurs. Rubberised asphalt depends on policy decisions from local and national authorities supporting initial higher spending and allowances on budgets to acquire future savings from the longevity in the product. The policy requirements and the instability that politically-inspired decisions carry with them are contributing to the unattractiveness of this solution to the entrepreneurial fraternity. Through government requiring a certain percentage of asphalt pavements to contain rubber (like in the United States of America (USA)), rubberised asphalt could be a very useful and viable option to produce. In the USA, the Environmental Protection Agency (EPA) recently avoided the return to coal in industrial kilns currently using TDF based on its beneficial carbon dioxide (CO2) emission and cost structures by defining TDF as Reasonably Available Control Technology (RACT) to existing coal-burning industrial kilns. In South Africa, the usage of TDF should be of interest to Eskom and the cement industry. TDF (produced from end-of-life tyres), defined as a renewable energy resource due to its proven biomass component and with its high calorific value, presents higher energy output values in comparison to coal and furthermore presents the industry with lower input costs per ton and reduces the CO2 emission factor. Entrepreneurial intervention involving Eskom and/or the cement industry in South Africa with the utilisation of end-of-life tyres as renewable energy resource is an overdue business opportunity. With more than ten million tyres per year available in South Africa and a stockpile of more than fifty million waste tyres, sustainability of TDF supplies is a reality. TDF is much cheaper per ton than coal and emits approximately 20 percent less CO2 and/or CO2e than low-grade coal to produce the same electricity output. From all the information gathered, it is clear that in countries where coal energy is extensively used, TDF utilisation not only reduces the tyre waste issues, but it also serves as an environmentally-friendly renewable energy resource in electricity production and cement kilns; the industry with some of the highest CO2 emission risks. The final chapter of this report presents a schedule representing the choice of tyre processing and disposal methods ranked by environmental preference and defining the priorities linked to process and product choice.

Повний текст джерелаThe Brazilian National Policy on Solid Waste (NPSW) entered into force in August 2010. Due to its recent implementation, many organizations are still adjusting to new visions that this law proposes in terms of waste management in the country. The supply chain of medical and hospital supplies is also part of this group of organizations that are currently in adaptation, and where new challenges regarding waste management have emerged. Due to the type of waste generated in health activities, this issue becomes important and deserves special attention from the agents of this supply chain. Much of the waste generated in health activities is considered a hazardous waste, and for that reason, the objectives of NPSW, such as reducing the volume and hazard of the waste, can put pressure on those involved in the production, consumption and disposal of this kind of waste. This study therefore aimed to identify the management of the medical and hospital supply chain in the state of Rio Grande do Sul, under the approach of NPSW. To achieve the objectives, different agents were approached, representing the three levels of the chain: 1 - suppliers of medical and hospital material, 2 - hospitals and 3 - companies specialized in the treatment of health waste. In order to enrich the results, governmental bodies were also addressed on their views towards health waste issues. Overall, the aim was to identify the existence or absence of collaboration between agents, the difficulties and opportunities in waste management and finally, the products and processes related to waste issues within this supply chain. The case study method was used and data was collected through interviews with managers of different agents in the supply chain of medical and hospital supplies in the state of Rio Grande do Sul. In total, 17 professionals from 11 health-related institutions were interviewed. As main results, it was possible to identify the absence of cooperation with the suppliers of the chain, and incipient collaboration between the remaining members. It was also possible to identify difficulties, as the increasing disposability of products, poor segregation and lack of adequate treatment for chemical products. The opportunities were presented as a possibility for governmental intervention - that could act as stimulus for the development of less aggressive products and increase the legal pressure on chain agents to comply with the legislation. Among the products and processes investigated, interviewees highlighted products containing raw materials that are less aggressive in their final disposal, reverse logistics and replacement of consumer products for services.

Повний текст джерелаThe Construction and Demolition Waste (C&DW), because of its high volume, brings high environmental social and economical impacts, therefore the worries about its management has grown. This management has always been responsibility of the governments. But with the Resolution 307 of CONAMA (Brazilian Environmental National Council) of July 22nd, 2002, it was transferred to the waste producer, which has to segregate it in four different categories and ship it to be recycled or disposed properly. The proposal is to create a method, based on system approach and operations research, to deal with C&DW management, respecting Resolution 307 guidelines. The proposed method encompasses the creation of a Waste Management Plan, whichconsiders the aspects of the project, to minimize waste generation; the segregation and transport within the construction site; and the final destination of the waste, including a method to control its segregation and shipping. Two construction sites were considered, one that did not have any kind of waste management and one on which the Management Plan was implemented. In addition, it was developed a simulation model using the computer software Arena 7.0, to analyze the Plan under different scenarios of generation, segregation and shipping of construction waste. As a result, a Plan of C&DW Management was proposed and validated, which is economic, social and environmental feasible and legally adequate, to be used by public and private professionals when dealing with the C&DW of their constructions.

The performance of the capitalist system, associated with urban areas, has contributed to the growth of solid waste scattered in urban centers of towns and cities, consisting mainly of materials that can be recycled. The generation of waste has assumed proportions that make this issue a major concern of any government, triggering several actions pertaining to the theme. One of the actions taken by the Rio Claro / SP was the creation of a Cooperative Collectors of Recyclable Material - COOPERVIVA, aiming to reduce the environmental impact generated by this waste and ensure an increase in the useful life of the county landfill, strengthening collective work through the Solidarity Economy and actions for Environmental Education. The actions developed by the cooperative have allowed the insertion of new collectors and increasing demand for recyclable waste collected by the cooperative. The need for collective management, aiming at personal development, the process of collective work of the group, the conditions for educated individuals and their relationship with the local government set up the goal of this work, which aims to propose management strategies more effective in daily life of each member, providing them with a work environment in a more differentiated and solidarity in order to provide an economic benefit and social practices with recognition and importance of the work that each member has developed in the city.
A atuação do sistema capitalista, associada aos aglomerados urbanos, tem contribuído para o crescimento dos resíduos sólidos espalhados nos centros urbanos de pequenas e grandes cidades, constituídos principalmente por materiais que possam ser reciclados. A geração de resíduos vem assumindo proporções que fazem desse assunto uma das principais preocupações de qualquer governo, desencadeando várias ações concernentes à temática. Uma das ações desenvolvidas pelo município de Rio Claro/SP foi a criação de uma Cooperativa de Catadores de Material Reaproveitável COOPERVIVA, com intuito de reduzir o impacto ambiental gerado por esses resíduos e assegurar um aumento na vida útil ao Aterro Sanitário do município, fortalecendo o trabalho coletivo através da Economia Solidária e ações voltadas à Educação Ambiental. As ações desenvolvidas pela cooperativa têm possibilitado a inserção de novos catadores e o aumento na demanda de resíduos recicláveis coletados pela cooperativa. A necessidade da gestão do coletivo, objetivando a valorização pessoal, o processo de trabalho coletivo do grupo, as condições de formação educacional dos indivíduos e sua relação com o poder público local configuram o objetivo desse trabalho, que resultou em estratégias de gestão mais eficazes no cotidiano de cada cooperado, proporcionando-lhes um ambiente de trabalho diferenciado e de maneira mais solidária, a fim de oferecer um benefício econômico e social com práticas de reconhecimento e da importância do trabalho que cada cooperado tem desenvolvido no município através de parcerias estabelecidas entre o poder público local e federal, instituições privadas e não governamentais, embasada na Política Nacional de Resíduos Sólidos (Lei 12.305/2010).

Повний текст джерелаToday, large amounts of fully functional materials are being thrown away within the construction industry of new buildings. This is a hidden problem, as the materials are not documented as leftover materials but in weight together with the other waste. The reason for disposal of materials is the pressure of time in the production; also, that there is no standard process to utilize the fully functional leftover materials when it occurs. Disposal of materials is considered to be easier, which requires less time and resources than by own initiative and commitment to take care of the materials. Recycling by reuse of materials is a huge gain for the environment. Production of materials accounts for the biggest environmental impact in the construction industry. By skipping the material manufacturing process, along with the managing and transportation that it entails, reduction of the environmental impact can be achieved. Recycling by reuse of materials and products implies that the manufacturing process can be avoided and the managing and transportation of materials would be reduced. In order to make reusing of leftover materials possible, a routine needs to be introduced at the companies and the different projects. This routine needs to be practically feasible and within reasonable financial limits.The purpose of this study is to investigate whether it is possible to establish a logistics centre where trading of fully functional material can be done. Environmental and economic aspects have been reviewed and compared with each other. Leftover materials and products will be gathered in a warehouse and then distributed for sale and reuse. A review of the costs and revenues that the logistics centre includes has been carried out in the form of a calculation. Interest and demand have been investigated as well. To motivate commitment to the reuse of materials, connections have been made between sustainable development, circular economics and environmental goals. The study has been carried out in cooperation with Skanska and is delimited to production of new residential buildings in the Stockholm area. The collected information is based on interviews and site visits. People that are involved in the production management of different projects have answered questions about their own experience regarding leftover materials, waste management, order and planning of materials, but also their own thoughts and opinions regarding potential solutions to the problem. Site visits have been carried out on a waste facility, various Skanska projects and a rental unit that Skanska itself operates. The answers from these interviews and the information from the site visits have been compiled and analysed.

Pese a los esfuerzos de buscar fuentes alternativas para subsanar el déficit energético, aún existen millones de personas que sufren la falta de accesibilidad a fuentes de energía moderna, situación que se debe a los altos niveles de pobreza bajo los cuales se encuentran inmersos. Junto a este inconveniente se suma el enorme incremento de residuos agrícolas en las comunidades andinas. Residuos que provienen de las actividades agrícolas, y que podrían ser perjudiciales para el medio ambiente si no se toman medidas adecuadas. Lamentablemente, en muchos países en desarrollo donde se generan grandes cantidades de estos residuos, se sabe poco sobre sus posibles riesgos y beneficios si no se gestionan adecuadamente. Uno de los enfoques más interesantes para abordar esta problemática, es el desarrollo de la gestión sostenible de los residuos orgánicos agrícolas de la región, transformándolos en recursos para la generación de energía renovable (biogás) y fertilizantes orgánicos (digestato). Esta solución permitiría dar una valorización energética a los residuos de la agricultura de la zona, sobre la cual basan su economía, y a la vez contribuiría a una mayor gestión de los residuos evitando el incremento de la contaminación ambiental. Con la finalidad de contribuir al desarrollo energético y mejorar el paradigma de la gestión de residuos en el área andina de Guaranda (Ecuador), la presente Tesis Doctoral aborda la evaluación del potencial bioquímico de metano (BMP) de los residuos orgánicos agrícolas de la región. Se realiza una cuantificación sistemática de la producción de biogás mediante la transformación bioquímica de residuos orgánicos agrícolas, que comprenden: sustratos principales (residuos de estiércol de vicuña, llama y cuy, y residuos de matadero de ganado vacuno) y cosustratos (residuos de paja de amaranto, quinua y trigo). El objetivo general de esta investigación de doctorado se ha llevado a cabo en cuatro fases: (I) Caracterización de la materia prima mediante el análisis elemental y proximal a través de los cuáles se estimó el rendimiento teórico y la biodegradabilidad de los sustratos y cosustratos, (II) Rendimiento de la codigestión de residuos orgánicos agrícolas con mezclas de lodos de aguas residuales en biodigestores batch, (III) Análisis de los efectos sinérgicos y antagónicos durante la monodigestión y codigestión de las materias primas y (IV) Evaluación de la cinética microbiana de la digestión anaerobia mediante los modelos de Gompertz modificado, transferencia, ecuación logística, modelo del cono y Richards modificado. En la caracterización fisicoquímica se determinó que las relaciones SV/ST de los sustratos y cosustratos oscilaron entre 58 y 77% con una relación C/N entre 12 y 102, lo que indicó que estos residuos son materias primas adecuadas para la producción de metano. En todos los ensayos un aumento de la cantidad de inóculo mejoró la biodegradabilidad de los sustratos y por consiguiente la producción metano; así, en la monodigestión se tuvo incrementos de hasta 90% y en la codigestión incrementos del 71%. Todas las mezclas produjeron efectos sinérgicos, donde los mayores porcentajes de metano se dieron cuando las mezclas de residuos de amaranto, quinua y trigo fueron del 50 y 75% de sólidos volátiles. Independientemente de la SIR1:1 y la SIR 1:2 se mejoró la producción de metano de la codigestión al incrementar el porcentaje de cosustrato especialmente de residuos de amaranto y quinua. Los mejores resultados de todos los ensayos realizados se obtuvieron en los biodigestores compuestos por residuos de matadero y residuos de quinua, donde se obtuvieron producciones de metano entre 581 y 555 ml
[CA] L'accés a fonts d'energia moderna en les àrees rurals de la regió andina és un dels factors principals per a disminuir la pobresa ja que el seu accés proporcionaria beneficis ambientals, econòmics i socials. Malgrat els esforços de buscar fonts alternatives per a esmenar el dèficit energètic, encara existeixen milions de persones que pateixen la falta d'accessibilitat a fonts d'energia moderna, situació que es deu als alts nivells de pobresa sota els quals es troben immersos. Al costat d'aquest inconvenient se suma l'enorme increment de residus agrícoles en les comunitats andines. Residus que provenen de les activitats agrícoles, i que podrien ser perjudicials per al medi ambient si no es prenen mesures adequades. Lamentablement, en molts països en desenvolupament on es generen grans quantitats d'aquests residus, se sap poc sobre els seus possibles riscos i beneficis si no es gestionen adequadament. Un dels enfocaments més interessants per a abordar aquesta problemàtica, és el desenvolupament de la gestió sostenible dels residus orgànics agrícoles de la regió, transformant-los en recursos per a la generació d'energia renovable (biogàs) i fertilitzants orgànics (digestato). Aquesta solució permetria donar una valorització energètica als residus de l'agricultura de la zona, sobre la qual basen la seua economia, i alhora contribuiria a una major gestió dels residus evitant l'increment de la contaminació ambiental. Amb la finalitat de contribuir al desenvolupament energètic i millorar el paradigma de la gestió de residus en l'àrea andina de Guaranda (l'Equador), la present Tesi Doctoral aborda l'avaluació del potencial bioquímic de metà (BMP) dels residus orgànics agrícoles de la regió. Es realitza una quantificació sistemàtica de la producció de biogàs mitjançant la transformació bioquímica de residus orgànics agrícoles que comprenen: substrats principals (residus de fem de vicunya, flama i cuy, i residus d'escorxador de bestiar boví), *cosustratos (residus de palla d'amarant, quinua i blat). L'objectiu general d'aquesta investigació de doctorat s'ha dut a terme en quatre fases: (I) caracterització de la matèria primera mitjançant l'anàlisi elemental i proximal a través dels quals es va estimar el rendiment teòric i la biodegradabilitat dels substrats i cosustratos, (II) Rendiment de la codigestión de residus orgànics agrícoles amb mescles de llots d'aigües residuals en biodigestores batch, (III) Anàlisis dels efectes sinèrgics i antagònics durant la monodigestión i codigestión de les matèries primeres i (IV) Avaluació de la cinètica microbiana de la digestió anaeròbia mitjançant els models de Gompertz modificat, transferència, equació logística, model del con i Richards modificat. En la caracterització fisicoquímica es va determinar que les relacions SV/ST dels substrats i cosustratos van oscil·lar entre 58 i 77% amb una relació C/N entre 12 i 102, la qual cosa va indicar que aquests residus són matèries primeres adequades per a la producció de metà. En tots els assajos un augment de la quantitat d'inòcul va millorar la biodegradabilitat dels substrats i per consegüent la producció metà; així, en la monodigestión es va tindre increments de fins a 90% i en la codigestión increments del 71%. Totes les mescles van produir efectes sinèrgics, on els majors percentatges de metà es van donar quan les mescles de residus d'amarant, quinua i blat van ser del 50 i 75% de sòlids volàtils. Independentment de la SIR1:1 i la SIR 1:2 es va millorar la producció de metà de la codigestión en incrementar el percentatge de cosustrato especialment de residus d'amarant i quinua. Els millors resultats de tots els assajos realitzats es van obtindre en els biodigestores compostos per residus d'escorxador i residus de quinua, on es van obtindre produccions de metà entre 581 i 555 ml/g VS.
[EN] Access to modern energy sources in rural areas of the Andean region is one of the main factors to reduce poverty, since its access would provide environmental, economic and social benefits. Despite efforts to find alternative sources to correct the energy deficit, there are still millions of people who suffer from the lack of accessibility to modern energy sources, a situation that is due to the high levels of poverty under which they are immersed. Along with this inconvenience is added the enormous increase in agricultural residues in the Andean communities. Waste that comes from agricultural activities, and that could be harmful to the environment if adequate measures are not taken. Unfortunately, in many developing countries where large amounts of these wastes are generated, little is known about their potential risks and benefits if not managed properly. One of the most interesting approaches to address this problem is the development of sustainable management of agricultural organic waste in the region, transforming it into resources for the generation of renewable energy (biogas) and organic fertilizers (digestate). This solution would allow to give an energetic recovery to the agricultural residues of the area, on which they base their economy, and at the same time would contribute to a better management of the residues avoiding the increase of environmental pollution. To contribute to energy development and improve the paradigm of waste management in the Andean area of Guaranda (Ecuador), this Doctoral Thesis addresses the evaluation of the biochemical potential of methane (BPM) of agricultural organic waste in the region. A systematic quantification of biogas production is carried out through the biochemical transformation of agricultural organic waste that includes main substrates (vicuña, llama and guinea pig manure residues, and cattle slaughterhouse residues) and co-substrates (amaranth straw residues), quinoa and wheat). The general objective of this doctoral research has been carried out in four phases: (I) characterization of the raw material through elemental and proximal analysis through which the theoretical performance and biodegradability of substrates and co-substrates were estimated, (II) Performance of the co-digestion of agricultural organic waste with mixtures of sewage sludge in batch biodigesters, (III) Analysis of synergistic and antagonistic effects during monodigestion and co-digestion of raw materials and (IV) Evaluation of microbial kinetics of anaerobic digestion using modified Gompertz models, transfer, logistic equation, cone model and modified Richards. In the physicochemical characterization it was determined that the VS/TS ratios of the substrates and co-substrates ranged between 58 and 77% with a C/N ratio between 12 and 102, which indicated that these wastes are suitable raw materials to produce methane. In all the tests an increase in the amount of inoculum improved the biodegradability of the substrates and consequently the methane production; thus, in monodigestion there were increases of up to 90% and in co-digestion increases of 71%. All the mixtures produced synergistic effects, where the highest percentages of methane occurred when the mixtures of amaranth, quinoa and wheat residues were 50 and 75% volatile solids. Regardless of SIR1:1 and SIR 1:2, the production of methane from co-digestion was improved by increasing the percentage of co-substrate, especially amaranth and quinoa residues. The best results of all the tests carried out were obtained in the biodigesters composed of slaughterhouse waste and quinoa waste, where methane productions between 581 and 555 ml/g VS were obtained. Regarding the kinetic modelling of the anaerobic digestion process, it was found that all the models fit the experimental values quite well with the predicted ones. In the monodigestion, in all the logistic models, the calculated asymptotes were adjusted very precisely for the specific yield (Me

Повний текст джерелаIn Brazil, management and solid waste disposal are problematic and can have major improvements to compliance with the guidelines of the Brazilian National Policy (PNRS), that points to the principles of the Integrated Waste Management (GIR), which indicates waste treatment and disposal diversification and final disposal as the last alternative. An important tool in the GIR is recycling, which in Brazil is structured based on the work of the waste picker, weakened actor within the Recycling Production Chain, which has no professional capability as the other members. Verifying the situation regarding the responsible delegated to the waste pickers in the future of the solid waste management, and its current condition, in a waste pickers association, It was found that the collectors consider themselves in an unequal position within the chain, and have need of commercial relations improvement. Upon the lack of equivalent professionalism of the waste picker with the other levels, it is clear that the recycling chain is committed at this point. This occurred because the structure of the association was limited in several respects. The PNRS assigns great importance to the collector, that here were not going to collect all the waste, because there is necessary improved in management. There is also the fact that there are some materials that they do not work for its non-viability. It was found that the recycling of certain materials will not occur naturally, requiring some type of intervention.

Formulations containing different proportions of such wastes in a clay matrix used for the production of bricks in a region near the pulp mill, in the north of Brazil, were homogenized, and then uniaxially pressed for the production of samples. The specimens were tested after drying at 110°C and after firing at the temperatures of 900 and 1000°C. Their ceramic properties were measured. The results indicated that it is technically viable the use of up to 10 wt.% of the wastes, still reaching adequate level of properties for the use of these products in the civil construction sector. These results show an important alternative for the destination of such wastes, representing an alternative in the continuous improvement of the environmental management of the cellulose production industries. With the increasing levels of cellulose production in the country, and the ongoing concerns about the environment, reduction in the waste disposal in landfills by incorporating them into new products helps to reduce the impacts on the environment and to reduce the volume of exploitation of mineral deposits.

This study aimed to verify if the recycling cooperatives implant the collectors of recyclable material, socioeconomically or not. The research was based on bibliographical and documentary review on the subject and also the comparative analysis of multi-case study in three recycling cooperatives located in São Paulo. We used to collect data from semi-structured interviews with cooperative members of these organizations and direct non-participant observation. The chosen approach was the analysis of qualitative data with the support of Atlas.ti software. The results will offer suggestions with proposals to managers, companies and policy makers so that the socio-economic inclusion is more effective. The main results of the study showed that the inclusion of collectors of recyclable material is processed with greater emphasis by the economic dimension in which the generation of employment and income become important factors to promote citizenship of these workers. It was observed in the cooperatives eager, but little effectiveness in implementing programs aimed at the social dimension as inclusion factor, in which the categories 'education' and 'health' could have priority in their management. It's worth mentioning that the analyzed recycling cooperatives comply with their proposals to provide access to work and therefore income. However, gaps in the social dimension could be minimized by the most action of public authorities and companies, in partnership with these collective social enterprises, in drafting of strategic plans that seek to actions aimed at increasing access to health and education programs and professional training of collectors
Este trabalho teve como objetivo verificar se as cooperativas de reciclagem inserem socioeconomicamente ou não os catadores de material reciclável. A pesquisa baseou-se na revisão bibliográfica e documental sobre o tema e também na análise comparativa de estudo multicasos em três cooperativas de reciclagem localizadas na capital paulista. Utilizou-se a coleta de dados a partir de entrevistas semiestruturadas com os cooperados dessas organizações e da observação direta não participante. O enfoque escolhido foi a análise de dados qualitativos com o apoio do software Atlas.ti. Os resultados permitirão oferecer sugestões com propostas aos gestores, empresas e formuladores de políticas públicas a fim de que a inclusão socioeconômica seja mais efetiva. Os principais resultados da pesquisa apontaram que a inclusão dos catadores e catadoras de material reciclável se processa com maior ênfase pela dimensão econômica, na qual a geração de trabalho e renda tornam-se fatores preponderantes para promover a cidadania desses trabalhadores. Observou-se por parte das cooperativas muita vontade, mas pouca efetividade na implementação de programas que visem à dimensão social como fator de inclusão, na qual as categorias educação e saúde poderiam ter prioridade em suas gestões. Vale destacar que as cooperativas de reciclagem analisadas cumprem com suas propostas de prover acesso a trabalho e, consequentemente, renda. No entanto, as lacunas encontradas na dimensão social poderiam ser minimizadas pela maior ação do poder público e das empresas, em parcerias com esses empreendimentos sociais coletivos, na elaboração de planos estratégicos que busquem ações direcionadas para maior acesso à saúde e aos programas de educação e capacitação profissional dos catadores de material reciclável

A melhoria nos processos produtivos em busca da eficiência na produção de novos bens e o crescimento populacional acompanhado pela elevação no consumo, ocasionam uma crescente geração de resíduos sólidos. Verifica-se que os problemas ambientais são decorrentes do perfil de consumo que as pessoas passaram a adotar ao longo dos anos, porém há um aumento de preocupação com a destinação adequada dos resíduos sólidos gerados pela sociedade. O reflexo desta preocupação são leis que foram criadas para proteger o meio ambiente. Um marco na legislação brasileira foi a Política Nacional de Resíduos Sólidos, que busca com o apoio dos empreendimentos de catadores de materiais recicláveis, realizar uma gestão correta dos resíduos sólidos urbanos. No entanto, no país, os empreendimentos que realizam a coleta, triagem e comercialização de resíduos sólidos, possuem níveis elevados de rejeitos ocasionados nas atividades internas. Sendo assim, o objetivo deste trabalho foi analisar o gerenciamento dos resíduos sólidos urbanos em dois empreendimentos de catadores de materiais recicláveis localizados na região metropolitana de Porto Alegre/RS para propor, a partir destes estudos, ações voltadas ao aumento da eficiência de triagem dos empreendimentos de catadores de materiais recicláveis instalados em vários municípios brasileiros. Foi possível observar que variáveis externas às atividades dos empreendimentos de catadores de materiais recicláveis, como veículo utilizado na coleta, influenciam nos níveis de rejeitos encaminhados aos aterros. Gerencialmente, a coleta seletiva é mais eficaz para obter melhor aproveitamento dos materiais potencialmente recicláveis. A COOTRE que realiza a coleta seletiva de RSU com caminhão com carroceria e tria com a esteira parada, apresenta eficiência de 97,1% na triagem dos materiais potencialmente recicláveis. Já a COOPERESÍDUOS que recebe RSU procedentes da coleta regular realizada com caminhão compactador e opera a triagem em uma esteira com velocidade de 20m/min, possui eficiência de 15,6% na triagem de materiais potencialmente recicláveis. Cabe considerar, contudo que, embora percentualmente esta eficiência seja bem menor que a da outra cooperativa, em função da quantidade de resíduos coletados nesta forma (regular com posterior triagem) ser muito maior, o resultado financeiro ainda é superior. A efetiva melhoria no processo está na mudança do sistema de coleta, de regular para seletiva, já que na coleta regular realizada hoje em São Leopoldo, 59,7% do total coletado é inadequado à reciclagem de inertes. Estes resíduos nem deveriam passar por qualquer triagem, sendo encaminhados diretamente para área de disposição final.
The improvement in production processes in pursuit of efficiency in the production of consumer goods and population growth accompanied by an increase in consumption, cause an increasing solid waste generation. It appears that environmental problems are arising from the consumption profile that people have adopted over the years, but there is a concern increased with the proper disposal of solid waste generated by society. The reflection of this concern are laws that are designed to protect the environment. A milestone in Brazilian law was the National Solid Waste Policy, which seeks the support of pickers of recyclable materials enterprises, conduct proper management of municipal solid waste. However, in the country, the enterprises that carry out the collection, sorting and marketing of solid waste, have caused high levels of waste in the internal activities. Thus, the aim of this study was to analyze the management of municipal solid waste in two projects of recyclable material collectors located in the metropolitan region of Porto Alegre / RS to propose, from these studies, actions aimed at increasing the enterprises screening efficiency of recyclable material collectors installed in various municipalities. It was observed that external variables to the activities of waste pickers ventures as a vehicle used in the collection, influence the levels of waste sent to landfills. Management, selective collection is more effective for better use of potentially recyclable materials. The COOTRE that performs the selective collection of MSW with truck body and with industry to stop treadmill, shows 97,1% efficiency in the screening of potentially recyclable materials. COOPERESÍDUOS already receiving MSW coming from the regular collection held with compactor truck and operates screening on a treadmill at a speed of 20m / min, it has 15,6% efficiency in the screening of potentially recyclable materials. It is worth noting, however, that although this percentage efficiency is much lower than that of the other cooperative, depending on the amount of waste collected in this way (with subsequent regular screening) be much larger, the financial result is even higher. The actual process improvement lies in changing the collection system regularly for selective, since the regular collection held today in São Leopoldo, 59,7% of the total collected is inadequate recycling of aggregates. This waste should not go through any screening being sent directly to final disposal area.
