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

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

Solid waste management in Mekong Delta: Review Paper

Nguyen, Xuan Hoang, Le, Hoang Viet 07 August 2012 (has links)
Municipal solid waste (MSW) in Vietnam has been increasing quickly and became one of the most considered environmental problems in Mekong Delta (MD) region covering 13 provinces and municipalities in the south of Vietnam. With a considerably large amount of MSW, the region produces about 5% of the total amount of MSW of the country. The collection rate of solid waste is about quite high (65 - 72%) in the cities and rather low (about 40 - 55%) in the rural areas, with a high content in organic matter (about 60 - 85%). The climate of MD can be characterized as tropical and monsoonal with a high rate of humidity and a strong impact of flooding. Like other regions too, the MSW collection and treatment system is still underdeveloped and rudimentary, with disposal sites being the sole dumping method of the unsorted MSW remaining untreated by any mechanical and biological pre-treatment steps. Within this paper, the current treatment, management and operation of MSW systems are introduced, as well as the identification of advantages and disadvantages, environmental impacts, potential risks of the MSW system within the impact of global climate change. The situation of MSW treatment and management is correlated with the climate change impact and the integrated solid waste management is introduced as a new approach for adapting the environmental protection awareness by considering the climate change for the longterm sustainable development orientation. / Sự gia tăng chất thải rắn ở các đô thị Việt Nam ngày càng nhanh và chất thải rắn đang là một trong những vấn đề môi trường được quan tâm hàng đầu. Đồng bằng Sông Cửu Long (ĐBSCL) nơi có đến 13 tỉnh và thành phố nằm ở phía Nam Việt Nam. Với lượng chất thải không nhỏ, chiếm khoảng 5 % tổng lượng chất thải rắn sinh hoạt của quốc gia. Tỷ lệ thu gom chất thải rắn thấp, chiếm khoảng 65 - 72 % ở thành thị, tỷ lệ này ở nông thôn thấp 40 - 55%, chất thải có hàm lượng hữu cơ cao chiếm khoảng 60 - 85%. Khí hậu nhiệt đới gió mùa với độ ẩm không khí cao và chịu ảnh hưởng lớn của lũ lụt hàng năm. Cũng như các khu vực khác, hệ thống thu gom và xử lý rác thải ở khu vực ĐBSCL còn rất thô sơ và lạc hậu, bãi rác là nơi duy nhất tiếp nhận trực tiếp hổnhợp rác thải không phân loại và qua bất kỳ công đoạn tiền xử lý nào. Trong phạm vi bài viết này, chúng tôi giới thiệu hoạt động vận hành hệ thống quản lý và xử lý rác đô thị trong khu vực đồng thời phân tích các thuận lợi và bất lợi, cũng như các tác động môi trường, những rủi ro tiềm ẩn trong điều kiện ảnh hưởng của biến đổi khí hậu toàn cầu - khu vực ĐBSCL là nơi chịu ảnh hưởng nặng nề nhất. Tình hình quản lý và xử lý rác được cân nhắc trong điều kiện tác động của biến đổi khí hậu, đồng thời quản lý tổng hợp rác thải cũng được đề xuất như một các tiếp cận mới nhằm đáp ứng nhiệm vụ bảo vệ môi trường trong điều kiện biến đổi khí hậu theo định hướng phát triển bền vững lâu dài.

Improving Solid Waste Management in Addis Ababa, Ethiopia. Based on the experience from Sweden, Östersund Municipality.

Haile, Hilab January 2016 (has links)
Lack of genuine concern for solid waste management practices and inefficiency of sol-id waste management system is one of the greatest environmental issues in Addis Ab-aba, Ethiopia. The Current Municipal Solid Waste Management System is extremely inefficient and ineffective. An illegal waste dumping, inefficient waste collection, and informal recycling are some of the issues that need to be immediately rectified. There-fore, this study was conducted in order to get a knowledge transfer from a developed country, Sweden, Östersund Municipality. The practical waste management and recy-cling activities undertaking in the city of Östersund have been assessed, evaluated and discussed in the study. Physical site visits, surveys, informal interviews, and group dis-cussions have also been conducted to be able to draw an immensely useful and tangi-ble recommendation for the improvement of Solid Waste Management and Recycling Scheme in Addis Ababa. Based on the experience acquired from Östersund the entire Solid Waste Management system in Addis Ababa has been evaluated and useful dis-cussions, recommendations, and conclusions have been drawn. Besides as recycling is one of the most significant waste management hierarchy components, it should have been given top priority in reducing the amount of waste generation in developing countries like Ethiopia. However, the recycling activities taking place in the country are highly limited and informal. Moreover, evaluation of the potential of recyclable wastes in Addis Ababa, discussion on how and why recycling needs to be given prece-dence and later comparison is made with Östersund Municipality in order to be able to gain knowledge from the Swedish experience. Besides, discussions were made in order to address decisive measures that need to be taken to implement the Swedish experience in the Solid Waste Management and Recycling sector in Addis Ababa Ethiopia in an environmentally friendly and economical way.

An investigation into sustainable solid waste management alternatives for the Drakenstein Municipal Area

Spamer, Ernus 12 1900 (has links)
Thesis (MBA (Business Management))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: The aim of this research report is to investigate sustainable alternative solid waste management methods for the Drakenstein Municipal Area in particular and South African municipalities in general. The point of departure is that landfilling alone is not sustainable and that alternative and/or complementary methods are required. Current solid waste management policies and practices in various countries all over the world are investigated in order to understand the global context of municipal solid waste management. The development of solid waste management in both developed and developing countries is considered in order to appreciate the different approaches and legal frameworks underpinning each approach. Several solid waste treatment methods, both established and advanced, are considered before the development of solid waste management in South Africa since 1992 is reviewed. An important aspect of evaluating alternatives is the identification of relevant stakeholders, key drivers for success and the constraints. An important conclusion reached in the research is that the lack of funding and the inherent inability of most municipalities in South Africa to render even basic municipal services currently make the introduction of advanced solid waste treatment methods non-sustainable. It is therefore suggested that the newly developed legal framework underpinning solid waste management in South Africa, be implemented in such a manner that all stakeholders are involved in the implementation of the basic principles of the waste hierarchy. The author believes that the introduction of technologically advanced waste treatment and disposal options will be premature if the basics of the waste hierarchy are not practiced by all. / AFRIKAANSE OPSOMMING: Die fokus van hierdie navorsingsverslag is ‘n ondersoek na volhoubare, alternatiewe vaste afvalbestuursmetodes vir Suid-Afrikaanse munisipaliteite in die breë en die Drakenstein Munisipaliteit in die besonder. Die basiese uitganspunt is dat vaste afvalstorting alleen nie volhoubaar is nie en dat alternatiewe/komplementêre metodes nodig word. Die vaste afvalbestuursbeleid en –praktyke wat tans wêreldwyd gevolg word, word ondersoek met die doel om die globale konteks daarvan beter te verstaan. Die ontwikkeling van vaste afvalbestuur in beide ontwikkelde en ontwikkelende lande word nagevors sodat die verskillende benaderings en wetlike raamwerke wat dit onderskryf, bestudeer kan word. Verskeie vaste afvalbestuursmetodes – beide gevestig en gevorderd – word bespreek waarna die ontwikkeling van vaste afvalbestuur in Suid-Afrika sedert 1992 onder die loep kom. ‘n Belangrike aspek van toepassing op die evaluering van alternatiewe, is die identfikasie van alle rolspelers, kritiese suksesfaktore en beperkinge. ‘n Belangrike bevinding wat gemaak word, is dat die gebrek aan voldoende fondse sowel as die inherente onvermoë van meeste Suid-Afrikaanse munisipaliteite om selfs basiese munisipale dienste te kan lewer, die implementering van gevorderde vaste afvalbestuursmetodes tans onvolhoubaar maak. In die verslag word dus aanbeveel dat die nuut-ontwikkelde wetlike raamwerk wat vaste afvalbestuur in Suid-Afrika reguleer, so geïmplementeer moet word dat alle rolspelers betrek word om die afval-hiërargie se basiese beginsels prakties toe te pas. Die outeur is van mening dat die implementering van nuwe, tegnologiesgevorderde vaste afvalbsetuursmetodes sal faal indien dit geïmplementeer sou word voordat die afval hiërargie voldoende toegepas word.

Sistema de avaliação da gestão integrada de resíduos da construção civil na esfera municipal / Evaluation system of integrated construction and demolition waste management at the municipal level. 2012

Lima, Rosimeire Midori Suzuki Rosa 23 April 2012 (has links)
Os Resíduos da Construção Civil (RCC) representam uma importante questão ambiental a ser considerada na gestão urbana dos Municípios. Os grandes volumes gerados e a sua destinação têm ocasionado diversos impactos ambientais ao meio urbano, com evidentes efeitos à saúde da população. Esta situação impõe aos gestores públicos a adoção de soluções mais eficazes para a gestão desses resíduos, sendo imprescindível o planejamento estratégico e integrado e a avaliação das ações implementadas. O objetivo desta tese é a proposição de um sistema de avaliação da gestão municipal dos RCC, de acordo com a Política Nacional de Resíduos Sólidos, Resolução CONAMA 307/2002 e demais resoluções pertinentes ao tema. A pesquisa exploratória foi desenvolvida em três etapas: i) revisão bibliográfica; ii) elaboração do sistema, considerando três eixos essenciais: universalidade dos serviços; proteção à saúde ambiental; e preservação dos recursos naturais, tendo como base a ferramenta FPEEEA (método de construção de indicadores) e iii) avaliação da gestão dos RCC de um município brasileiro utilizando o sistema proposto para verificar a sua aplicabilidade e identificação de fragilidades e potencialidades da gestão. Como resultado, é apresentado o Sistema de Avaliação da Gestão Integrada dos RCC denominado SAGI-RCC para apoiar a gestão no âmbito municipal. Este sistema propõe ações para a gestão integrada e os respectivos indicadores para monitorá-las, de forma que se constitui em uma ferramenta para ser inserida em processo de melhoria contínua da gestão municipal desses resíduos. Este sistema visa induzir os gestores municipais à reflexão a respeito da gestão de RCC e o SAGI-RCC permite avaliar o atendimento da gestão dos RCC às dimensões da sustentabilidade no âmbito municipal. Além disso, pode ser aplicado a distintas realidades, pois os valores para a avaliação são adaptáveis às condições locais. Quando aplicado a um município de médio porte (cerca de 500.000 habitantes), constatou-se que o conjunto de indicadores que compõe o SAGI-RCC é relevante, pois abrange as diferentes dimensões de sustentabilidade da gestão integrada, estabelecidas pela Política Nacional de Resíduos Sólidos, além de identificar fragilidades e potencialidades da gestão de RCC deste município. / Construction and demolition waste (CDW) is an important environmental issue to be considered in Municipal Urban Management.

This requires public managers to adopt more effective solutions to manage these wastes such as the implementation of integrated strategic planning and evaluation of actions which are extremely necessary. The aim of this work is to propose an evaluation system for municipal construction waste management, according to the premises of the National Policy for Solid Waste; Resolution 307 issued by the National Environmental Council (CONAMA) and other theme related resolutions. Exploratory research was carried out in three steps: i) literature review; ii) development of the system, considering three main pillars: scope of the service, environmental health protection and preservation of natural resources, based on the FPEEEA tool (methods for building environmental health indicators) and iii) assessment of CDW management in a Brazilian city using the proposed system to verify its applicability and identify its management strengths and weaknesses. As a result, the Evaluation System of Integrated CDW Management - called SAGI-CDW is presented to give support to management at a municipal level. This system proposes action towards integrated management and the respective indicators to monitorate, so that it becomes a tool to be inserted in CDW Municipal Management Continuous Improvement Processes. This system aims at inducing city managers to reflect on CDW management, and SAGI-CDW can assess the CDW management action strategies in terms of extension of sustainability at a municipal level. Moreover, it can be applied to different situations, because the parameters for evaluation are adapted to local conditions. When applied to a medium size city (approximately 500.000 inhabitants), it was found that the set of indicators that make up the SAGI-CDW is relevant as it covers the different dimensions of sustainability for integrated management established by the National Policy for Solid Waste, and also identifies weaknesses and strengths of this municipalitys CDW management.

Towards an inclusive municipal solid waste management system: A case study from Xalapa, Veracruz, Mexico

González Acosta, Andrés January 2017 (has links)
The city of Xalapa, like many Mexican cities, does not count with any sort of official recycling program. Resource recovery relies on the work performed by the informal recycling sector and often, such work is neglected by the local government. In line with this, the aim of this study is to evaluate if a participatory resource management is a more suitable option than the current approach; so that the informal recycling sector can be included into the formal waste management system. In order to do so, this study employed a case study method using qualitative data; during the month of field work in Xalapa, semi- structured interviews and observation were the techniques used for collecting data. Concepts such as informal economy, participatory resource management, network theory and waste management were employed to analyze the organization and operation of the formal and informal waste management systems. Drawn from the results and analysis, it was presented that the informal recycling sector in Xalapa is composed of 5 different types of actors. Some of these actors are organized, while others work independently. The study revealed that their income is related to their capability of accessing to infrastructure and resources. This access to infrastructure and resources takes the form of a secondary materials trade hierarchy where the income of an actor depends on their ability to add value to their recovered materials. Additionally, organized actors tend to be less prone to manipulation and exploitation. Furthermore, it was deemed relevant to look at the current policies and regulations as well as to the action plans proposed by the local government for alleviating the solid waste crisis in Xalapa. It was identified that to consider a participatory resource management approach, several barriers need to be overcome; these barriers lie within the governance and social spectrum. However, despite the identified barriers, the current waste management system has opportunities for creating a more inclusive and socially just municipal solid waste management system.

The policy and practice of reclaimer integration in the City of Johannesburg

Sekhwela, Maite Mmakgomo January 2017 (has links)
A dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science (Geography). Johannesburg, 11 June 2017. / Reclaimer integration in South Africa has been identified as a priority, but how to integrate reclaimers remains a challenge. Crucially, there is not yet a coherent approach or a clear understanding of what reclaimer integration means in South Africa, let alone whether this same understanding of integration is shared by the reclaimers who are being integrated. By focusing on the integration initiatives of the Environment and Infrastructure Services Department (EISD) and Pikitup, this thesis conducts a comparative study of two reclaimer integration projects in Johannesburg. It investigates the breakdown and mismatch of understandings between social actors who do not share the same view of integration and implications thereof. In doing so, it contributes to discourse on the transformation of Johannesburg’s waste management system. Social constructivism theory by Berger and Luckmann (1966) provides the theoretical grounding for this dissertation by exploring how different milieus and experiences shape people’s understanding of realities. Findings illustrate that there is no clear conceptualisation of integration that underpins waste management policy. Drawing on social constructivism theory, the paper concludes that integration is a socially constructed and contested concept. Essentially, there are inconsistent understandings of integration among different groups of reclaimers as well as officials. For that reason, integration programmes created a new form of exclusion and imposed negative effects on reclaimers. KEYWORDS: Integration, Reclaimers, Waste, Policy, Recycling, cooperatives / LG2018
