Uppföljning av kommunala avfallsplaner : - Ett steg mot en hållbar utveckling?

Nordmar, Malin January 2022 (has links)
The purpose of this study was to investigate how successful the goal and follow-up measures of the municipal waste plans are, but also how the follow-up measures can contribute to achieving environmentally sustainable development in accordance with the national environmental diversity goals. Methods used were a literature study and a questionnaire, which was sent to people responsible for the follow-up of the waste plans. The results of this study showed that a large part of the follow-ups worked well. The national environmental diversity goals were integrated through various activities in the waste plans, for example information efforts regarding minimizing plastic use. It was not possible to see any statistical differences between follow-up frequency and municipality size. However, the common aspect was that an improved structure would improve the goal and measures fulfilment. A part of the survey was to investigate the need for a structured digital system for monitoring the waste plan. In order to function and be adequate, it was important that the digital system was integrated into the company's own operations. A structured digital system for monitoring the waste plan can increase recycling rates. It can contribute to increase the chances of achieving the national environmental diversity goals and reach circular economy.

Handbook of Waste and Network of Re-use

Chavosh, Ardalan January 2012 (has links)
The intelligent handling of waste is a pressing issue today. Up until the 19th century it had been however an integral part of societies especially when it comes to the waste generated by construction and demolition (Bahamon and Sanjines, 2010). After industrial revolution (1750-1850) which opened the gates of mass production and mass consumption followed and supported by two major forces of capitalism and the dramatic increase in world population, the generation of waste accelerated correspondingly and in a global scale. The mass extraction of natural resources on one hand (limited amount of natural resources), and the problems caused by waste landfilling and incineration such as pollution and diseases on the other hand, made us stop this linear extraction-to-waste trend and recognize recycling as a solution. Recycling chiefly addresses a sustainable approach to reduce the negative effects of waste and at the same time involves processing used materials (waste) into new products to prevent waste of potentially useful materials (Eco Cloud), however through recycling not only some energy has to be consumed to make this process run but also some portion of pollution would be generated as a side effect. What is more is that up until today recycling has been neither in many cases economically profitable nor has it been possible to recycle all the amount of waste. For instance In US- as the most consuming society on the planet Earth- only 34% of the municipal solid waste can be recycled and the rest ends up in either landfills or incinerators (EPA,2010). This project is to mainly focus on the definition of a rather comprehensive network (Network of Reuse) which sits right before recycling through which as much as possible of the total amount of waste could be directly absorbed back into the society (with minor changes in some cases) in different scales, the resultants of which would be claimed not to be only less energy consumption and less pollution caused through processing waste (as in recycling) but also avoiding a considerable amount of unrecycled materials from ending up in landfills and incineration. In fact the assumed network-which is simulated by the smart grid model- could be said to be a complementary section added to the existing trend today and is on no account against recycling. Like any other network, the network of reuse is based upon strategies, tools, and policies. The rhizomic growing structure of this network-that is in contrast to the tree structure of recycling- suggests a bottom up movement in handling waste and empowering people while the proposed time-line strategy is assumed to be moving from entertainment towards a coherent business network. In fact the project itself suggests the necessity of more bottom up structures to happen in our future planning. The entire project is highly founded upon research and could be applied in a variety of actual designs and concrete cases. Therefore, in this project no specific site is being addressed directly but the actual need for adding the supposed network is explored.

Evaluation of municipal solid waste illegal disposal in Masvingo City, Zimbabwe: towards a sustainable solid waste management model

Chireshe, Amato 11 1900 (has links)
Municipal solid waste management (MSWM) is a global problem as most local authorities fail to dispose MSW safely. In view of this, the study was aimed at evaluating environmental and health risks associated with municipal solid waste (MSW) illegal disposal as well as constraints faced by Masvingo City in MSWM, with a view to developing an alternative sustainable management model. The study, informed by the philosophy of pragmatism, employed a mixed methods design in which quantitative and qualitative data werecollected concurrently. Questionnaires comprising both close and open-ended questions, semi-structured interviews and site visits were used to collect data. The study population comprised participants from Masvingo City’s residential areas, Masvingo City Council employees, Environmental Management Agency (EMA) officials and informal waste pickers. A sample of 406 participants, comprising 354 residents from high-density, 16 residents from medium-density, 24 residents from low-density suburbs, six council employees, two EMA officials and four informal waste collectors participated in the survey. Concurrent triangulation was employed to analyse data. Basic numerical analysis was used for quantitative data while thematic data analysis was employed for qualitative data. Three main findings which emerged from the study were (a) Land pollution, air pollution, surface water pollution and loss of urban beauty, were the main environmental risks as at least 59 % of the respondents noted the four as environmental risks associated with illegal municipal solid waste disposal (b) Cholera, skin problems and malaria were the main health risks; and, (c) The main constraints related to MSW management were inadequate environmental education, lack of cooperation and participation from waste generatorsand lack of resources by Masvingo City . From the findings, 66 %, 52 % and 49 % of participants noted inadequate environmental education, lack of cooperation and participation, and lack of resources respectively as constraints faced by Masvingo City in MSWM. Basing on the findings of the study, it can be concluded that MSW disposal in Masvingo was a threat to the environment and human health and, as a result, a sustainable MSWM model was developed for Masvingo City. / Environmental Sciences

Spatial distribution of residential solid waste generation in Brazil: estimating residential solid waste generation and CO2eq emissions based on the nominal income, towards the achievement of the Sustainable Development Goals

Redivo, Andre Luciancencov 22 July 2021 (has links)
The generation of solid waste is a natural consequence of human life. Its rate has increase rapidly along the years, mostly due to the population growth, urbanization process coupled to industrialization and economic development. The uncontrolled disposal of solid waste in unsuitable sites, dump sites, has poses a threat to public health and the environment. In this regard Global efforts has been made to rethink municipal solid waste management toward sustainability. Middle- and low-income countries, such as Brazil, should seize the opportunity and centre efforts in the development and strengthen of an inclusive municipal solid waste management, supported by an innovative public policy where all government levels are integrated and focused on resource recovery and recycling through the organization and strengthening of waste pickers, in order to act directly in the income improvement of a marginalized portion of society as a result of the revenue generated by recovered and recycled materials sales, as well as reduce the CO2eq emissions consequent from the disposal of solid waste, among others, hence moving these countries towards the achievement of the SDG goals. In this regard, a well managed inclusive municipal solid waste system requires a reliable data source to support decision makers in the design of public policies with effective actions in the field, otherwise innovative and modern public policies will be filled with fruitless actions, thus, wasting the aptitude of the municipal solid waste management system in help middle- and low-income countries to successfully carry out the SDGs goals. Nevertheless, the estimation methods are a valuable tool for decision makers in middle- and low income countries to outrun the lack of solid waste information and doing so, increase the effectiveness of public polices towards a sustainable and inclusive municipal solid waste system, focused on mitigate negative impacts in the environmental sphere and potentiate the positive outcomes in the public health and human development sphere in these countries. This research proposed an estimate method based on the nominal income which is able to provide a reliable estimate of the residential solid waste generation, as well as its spatial distribution in the municipal level and within the municipal boundaries. The proposed approach has the ability to differentiate spatial distribution of the residential solid waste generation, weighting not just the number of people living in a determined space, but also the purchase power of those people, providing a more accurate view of the issue, which benefits decision makers to design and plan their polices and actions. / Graduate

Análisis de los Beneficios de la implementación del principio de Responsabilidad Extendida del Productor (REP) en los neumáticos fuera de carretera en el Perú / Benefits achieved by implementing the principle of Extended Producer Responsibility (EPR) in off the road tires in Peru

Peña Palomino, Sonia Marisol, Rios Casstell Burgos, Bletsy 03 August 2020 (has links)
En los últimos años los países prestan atención con el cuidado y protección del medio ambiente, por ello se dictaminan normas y leyes que incentiven el buen manejo de los residuos sólidos. En el Perú existe el Decreto Legislativo 1278 Ley de Gestión Integral de Residuos Sólidos, pero la inadecuada disposición de los neumáticos en desuso genera problemas ambientales y de salud. Más aún, no se aprovechan las materias primas de estos bienes para convertirlos en otros productos aplicando la Economía Circular, es decir priorizando la recuperación y valorización de estos productos; lo que conlleva a una reducción en la generación de residuos sólidos. La presente tesis consiste en conocer los beneficios de la implementación del principio de la responsabilidad extendida del productor (REP) en los neumáticos “fuera de carretera”. (OTR por sus siglas en inglés [off the road]). En ese sentido, en el capítulo I se presenta el contexto del problema de investigación, así como la formulación del problema y sus respectivos objetivos. El capítulo II busca contextualizar la situación global, regional y nacional sobre el principio REP en los neumáticos. En el capítulo III se aborda la metodología, los segmentos y categorías referente al tema de investigación. En el capítulo IV se desarrolla los resultados obtenidos y finalmente, en el capítulo V se recaban, interpretan y analizan las conclusiones y recomendaciones de estudio. Asimismo, se detallan las barreras y brechas de investigación. / In recent years, countries pay attention to the care and protection of the environment, so regulations and laws are enacted that encourage the good management of solid waste. In Perú there is the Law 1278, but the inadequate disposal of tires out of use generates environmental and health problems. Furthermore, the raw materials of these goods are not used to convert them into other products by applying the Circular Economy, that is, prioritizing the recovery and valuation of these products; which leads to a reduction in the generation of solid waste. This thesis consists of knowing the benefits of implementing the principle of extended producer responsibility (REP) in “off-road” tires in (off the road]). In this sense, Chapter I presents the context of the research problem, as well as the formulation of the problem and its respective objectives. Chapter II seeks to contextualize the global, regional and national situation regarding the REP principle in tires. Chapter III deals with the methodology, segments and categories related to the research topic. Chapter IV develops the results obtained and finally, Chapter V collects, interprets and analyzes the conclusions and study recommendations. Likewise, the barriers and research gaps are listed. / Tesis

Gör vi allt vi kan eller allt vi vill? : En undersökning om inställning till sortering och minskning av hushållsavfall inom enfamiljshushåll i Örnsköldsviks kommun. / Are we doing everything we know or everything we want? : A study about attitudes towards sorting and reducing household waste in single family households in municipality of Örnskäldsvik.

Lindström, Jenny January 2021 (has links)
The aim of this study is to examine the main reasons for and obstacles to single family households sorting household waste. Focusing on a population between ages 35 and 45 and 65+, it also examines motivating factors, reasons, and obstacles to reduce total household waste. Worldwide, the problem of greenhouse gases and dioxins because of waste is still unresolved. The national environmental legislation state that everyone is responsible to handle their waste in a way that does not harm people or the environment. Previous investigations regarding waste, conducted by waste company Miva, situated in municipality of Örnsköldsvik, show that improvements can be done by the citizens. The current project involves a survey sent to 789 households and answered by 302. Results from the survey combined with eight telephone interviews showed the following: people sort their waste mainly for environmental reasons but sometimes they find it easier not to sort at all, often because of very dirty packaging or simply convenience. Both age groups have the will but do not experience the possibility to reduce their overall waste. Higher waste management cost does not motivate people to improve their recycling habits, but personal feedback seems to be an effective way to reach higher motivation. To reach further improvements and reduce waste the citizens of Örnsköldsvik might need to change their consumption habits and producers take their responsibility regarding packaging. Further research to what impacts consumer behaviour is needed.

Implementation of Green and Lean manufacturing in post processing activities : A qualitative case study at a barrier coating facility

Tagesson, Daniel, Karlsson, Isak January 2021 (has links)
To reach the sustainable development goals of agenda 2030, mankind must continuously work towards developing sustainable industrial processes. The concept of Total Quality Management, Lean/Green manufacturing has been frequently applied separately, but studies indicate that the combination of the concepts can yield synergically benefits from an economic and environmental perspective. The process industry has a continuous flow of residuals which is a potential opportunity to gain a competitive edge through eliminating waste and embracing a circular economy system. The lack of exploring operational methods to achieve better results in relation to waste management and utilization of waste have inspired this thesis. This study has established a chain of events that enable other researchers and managers to find, define, explain and solve problems connected to waste management systems. The results indicate that it is possible to find opportunities within the organization to reuse already procured resources but also that the utility of storage vessels is connected to the overall efficiency of the waste management system. Interestingly, the results also indicate that there is an industrial culture related to the case that hampers the increase of efficiency which can be explained by the cornerstones of Total Quality Management and Lean manufacturing. Lean waste i.e., unused creativity thrives and hampers new ways to decrease cost and lower environmental impact when employees are not encouraged to communicate or innovate. Monetary gains and environmental savings is achievable by measuring, including and involving personal combined with a dedicated management. / <p>En väl genomförd och beskriven studie där studenterna lyckas ge bidrag av både praktisk naturoch teoretisk.</p>

Corporate Recycling Behavior Through the Lens of Situational Factors : Case study at Tarkett AB in Ronneby

Remle, Christian, Bertilsson, Carl-Philip January 2018 (has links)
Introduction: The unsustainable recycling patterns of various companies in Sweden lead to a waste of possible resources. These resources can create value through re-production in circular processes. The issue that this study address is the recycling behavior among workplaces. There is a gap in the research of understanding influences to recycling behaviors among industrial companies, which is the target in this study. Theory &amp; Purpose: This thesis employs behavioral theories on recycling activity through a framework developed by the authors with the aim of determining factors that affect the present recycling behavior within industries. Therefore, the purpose will be to investigate recycling behavior of companies within the flooring industry in Sweden. Furthermore, its purpose is to broaden the knowledge about recycling among companies and what situational factors that affect recycling behavior. Methodology: For data gathering, the thesis followed a quantitative method through conducting an online survey. The survey was sent out to 190 companies, and this resulted in 55 respondents which is a response rate of 28.9%. The survey data were collected to evaluate the prediction of behavior by the use of statistical regression analyses in STATA. Ordinal and binary data were the primary data types collected and used. Analysis &amp; Results: A Probit regression model tested the survey data followed by calculations of the marginal effects. Marginal effect is used to conclude how much each situational factor provoked the probability of RECYCLING BEHAVIOR when the other factors are unchanged. The analysis made the support that RECYCLING BEHAVIOR is significantly related to the factors INFRASTRUCTURE, CONVENIENCE and ORGANIZATION COMMITMENT. Furthermore, there is an existence of latent factors affecting recycling behavior. This existence is because the statistical model partly explains the connection. Alternative factors should be investigated in further research since there are limited studies done on the topic. Conclusions: Considered benefits are for; the flooring industry as well as other industries and society at large. The understanding of enablers for influencing RECYCLING BEHAVIOR is one of the benefits of this study. Changes in arrangement and mobility of recycling stations, together with an increase of social norms and recycling policies, suggests being practical goals. Moreover, communicating these standpoints are important for companies to gain value. Nonetheless, protecting the environmental boundaries by decreasing the use of raw material in a growing global production market. Understanding how situational factors affect RECYCLING BEHAVIOR will help actors move towards more sustainable and circular acts. Regarding recycling among industries, this study can be used to understand how to gain more value in existing circular economy systems as well as waste management systems. Both economic value and ecological value can be determined, from putting waste material into new products instead of incinerating it. Future Research: Directions for future research include qualitative case studies, experimental testing, and models including internal factors, attitude, habits and subjective norms. Extending this thesis with other approaches will benefit to find further correlations and predictions regarding recycling behavior among companies. Further research should also include economic aspects of the material gained through recycling behavior.

Sustainable and innovative waste management loops : A study on Saint-Gobain and ISOVER’s waste management strategy

Picart, Inès Clémence, Rauf, Ramla January 2021 (has links)
Background: Despite the obvious attraction for “greener” solutions in all industries, the different sustainable measures adopted by governments, business associations, andbusinesses themselves, the remaining high number of landfilled solid wastes from allindustries per year, especially the construction industry, suggests that a waste managementtowards valorisation is not systematically the first chosen option for the firms collecting the wastes. Purpose: To increase awareness, develop knowledge and show how collaboration within abusiness ecosystem and adapted corporate strategy allows the development of sustainablewaste management. Methodology: A comparative case study on the waste valorisation and innovation creationprocess, approached throughout a semi-structured qualitative data collection of fivepractitioners within a similar business ecosystem. Findings: The findings indicate that mutli-strategy level collaboration within and betweenbusiness ecosystems is a nursery for the development of innovation in the context of waste valorisation.

Sustainable Recycling Systems: A Global Responsibility

El Radaf, Veronica January 2020 (has links)
In the world today, thousands of humans in developing countries live in metropolises anddepend on garbage for their livelihoods. In Cairo, waste has been taken care of by aChristian minority group called the ‘Zabaleen’.This Bachelor thesis was conducted in Cairo and financed by a Minor Field Studyscholarship in August-October 2012. It focuses on Egyptian citizens’ attitudes towards asustainable recycling system and their attitudes towards the traditional garbage collector‘Zabaleen’. I used focus groups as the main source for collecting data and the technique ofshowing photographs to create a dialog among the participants. The focus groups have led to dynamic and useful discussions that this study is based upon. In conclusion, onecommon attitude that was met in the study indicates the frustration of how dirty the streetsof Cairo are. People all said they wanted a clean Egypt but they felt that no one from thegovernment wanted to put their finger on the solution to this problem.
