Sustainable Waste Management and Service Quality Delivery in Nigeria

Waste disposal, collection and treatment is an indispensable facet in the developmental phases of rural and urban cities across the globe. The accumulation, disposal and treatment of waste in urban centers have become a predicament to both private and public stakeholders in Uyo metropolis, Akwa Ibom State, Nigeria. The objective of this study is to examine sustainable waste management and service quality delivery in Nigeria. The issues to be addressed by this study include; attitude of residents towards waste disposal, non-conformity with modern waste collection/treatment processes, and the waste management infrastructural gaps. The study adopted the 9 Development Band global theory of waste and development - using Integrated Sustainable Waste Management – ISWM approaches, with a model elucidating the effects of waste management on environmental footprint. Descriptive survey technique was adopted in which, questionnaire was administered to 384 respondents in the metropolis, as well as the conduct of in-depth interview to obtain additional information on issues that were not clarified in the structured questionnaire. Data collected from the field were collated and analyzed using Pearson Correlations Analysis Technique, to ascertain the relationship between the dependent and independent variables. The findings of the study revealed unwholesome and unsustainable approaches in waste disposal/management, and suggest effective service delivery approaches in line with the 9DB model ISWM. The study recommends that residents should dispose waste in line with established waste disposal procedures, waste management authorities should adopt efficient and sustainable waste collection and treatment approaches. If these suggestions are implemented; it could reduce the metropolis environmental footprint, mitigate on the current global climate change challenges, and promote the UN-SDG - 11 which anchors on the need for sustainable cities and communities.

Solidaritas Bank Sampah Berseri: Alternatif Program CSR Berbasis Pengelolaan Sampah Berkelanjutan Terintegrasi

This article aims to describe PT Pertamina Patra Niaga IT Balongan's CSR empowerment program based on integrated sustainable waste management in the Langgen Block, Singaraja Village, Indramayu. The initial initiation came from a resident's anxiety about the slum and dirty surrounding environment as a trigger for tidal flooding and digestive diseases. Since 2019, this waste management has been carried out based on solidarity from the collective consciousness and self-subsistent of the surrounding community, assisted by the village government through village funds. Then starting in 2021, this activity and its managers will become foster partners of PT Pertamina Patra Niaga IT Balongan CSR in the Serial Waste Bank CSR program. This study uses a descriptive qualitative method with observations and interviews with residents and managers of the Berseri Waste Bank including literature studies. The results of this study indicate that the Berseri Waste Bank CSR Program is an alternative CSR program that represents an integrated sustainable waste management pattern that has a broad impact on the environment, social, economy and welfare with the concept of Integrated Sustainable Waste Management (ISWM). Keywords : CSR, Integrated Sustainable Waste, Management Waste Management, Solidarity, Waste Bank.

The development of sustainable IoT E-waste management guideline for households.

The introduction of new technology, such as the Internet of Things (IoT), entails a growth in digital devices, which could ultimately result in a high amount of electronic trash (e-waste) production if they are not appropriately managed. Apart from that, the regulation on possible "IoT E-waste" generation is yet to be regulated, probably due to the new development and implementation of IoT globally. Hence, this paper proposed a Sustainable IoT E-waste Management guideline for households. This guideline could assist government agencies and policymakers in their strategies, planning, development, and implementation of a sustainable household IoT e-waste management initiatives in Malaysia. This study is an exploratory study that adopts a qualitative case study research method. The guideline was developed based on the Integrated Sustainable Waste Management (ISWM) Model. This guideline contributes to Malaysia's sustainability agenda in reducing carbon emissions intensity towards 2030 by 45 percent.

Review of guidelines for sustainable municipal waste management: best practices in Brazil

Current integrated management systems involve several dimensions since sustainability has among its fundamental principles the protection of public health and the minimisation of environmental, social and economic impacts. The aim of this study was to provide a review of guidelines for achieving integrated sustainable waste management (ISWM) by presenting a selected best practice in Brazilian cities. A systematic literature review was undertaken to identify current systems and best practices in waste management. The results evidenced the significant role played by all the actors involved (population, private sector, authorities and non-governmental organisations). Political, legal and institutional guidelines ensure an adequate management planning through technical studies, drafting of legislation and technical and operational structure for the provision of services. The economic aspects guarantee the financial sustainability of the system. The socio-environmental guidelines provide for the minimisation of environmental impacts through the reduction of waste generation and social inclusion. The best practices in Brazil showed that municipalities that adopt sustainable integrated management have higher rates of recycling, social engagement, social inclusion, economic sustainability and reduced impacts on the environment. These guidelines serve as a planning tool for any local government to structure an ISWM system.

Sustainable Glass Recycling Culture-Based on Semi-Automatic Glass Bottle Cutter Prototype

Humanity has developed recycling activities over time due to their benefits, the shortage of raw materials, or the footprint with regard to the environment. The absence of a recycling culture in Mexico has not allowed its development and growth despite the benefits. In 2012, Mexico only recycled less than 10% of urban solid waste. Most recycling activities are focused on plastic, paper, and cardboard products due to their prices in local markets. This article presents a semi-automated prototype focused on recycling glass bottles using the thermal shock phenomenon. It aims to develop a sustainable glass recycling culture by creating a new branch for the integral glass recycling process and a proposal base on Integrated Sustainable Waste Management (ISWM) and the Quintuple Helix Model. It helps to reduce waste and resource recovery from recycling and upcycling glass bottles. The products obtained from upcycling fulfill new uses and acquire new value, while glass leftovers continue the integral recycling process for glass. Additionally, this paper demonstrates the relation between the ISWM and the Quintuple Helix Model and the opportunity to implement the twelfth Sustainable Development Goal (SDG).

Sustainable Waste Management for a City Multifloor Manufacturing Cluster: A Framework for Designing a Smart Supply Chain

This study focuses on integrated sustainable waste management (ISWM) within a city multifloor manufacturing (MFM) cluster. Manufacturing activities in residential areas of the urban environment and the associated generation of municipal production waste (MPW) are serious problems. The primary goal of this study is to design smart supply chain (SSC) scenarios for the shipment of MPW from a city MFM cluster under uncertainty. This paper presents a new model of the finite MPW generation capacity for a city MFM cluster on the basis of an analysis of its finite production capacity using the material flow analysis (MFA) methodology. The proposed model allows us to determine the number of transport fleet units needed for the implementation of various supply chain (SC) scenarios of MPW. To select the best scenario for MPW shipment in real time, the application of SSC and SSC management (SSCM) technologies is proposed. SSCM performance indicators are proposed which allow us to evaluate the efficiency of using vehicles for cluster MPW transportation. The numerical values of the SSCM performance indicators for various options regarding the handling of city MFM buildings using trucks are obtained. These evaluations form the basis for the decision-making and planning associated with the SSCs of MPW.

Improving urban household solid waste management in developing countries based on the German experience

Countries worldwide strive to improve their urban household solid waste management (UHSWM) practices. While developed countries like Germany have achieved good results with different UHSWM initiatives, developing countries still struggle to be effective with their waste management (WM) policies. With an interest in learning from the German experience, this paper provides a cross-case analysis between a German and a Brazilian city that can be of practical relevance to improving UHSWM in developing countries. The paper uses “process flow diagram” (PFD) and “wasteaware benchmark indicators” for integrated sustainable waste management (ISWM). Both methods confirmed the German city as a benchmark and attested the inefficiency of the Brazilian UHSWM. The total maximum score weightage percentage of the matrix quantification difference was significant, 98% against 50%. Findings highlight viable solutions based on the three pillars of the German solid WM system: clear laws, regular public campaigns, and fee methodology. The formalization and improvement of Brazilian UHSWM require better governance to obtain additional investments. Herein, the application of the Green Dot methodology, sponsored by industry and consumers in Germany, would enable an increase of up to 318% of the values received by a typical Brazilian cooperative. This additional investment can empower a sustainable solution where the population could opt to work with recycling, either as a formal employee or as a formal entrepreneur, shedding more light on the social pillar of the triple bottom line. Moreover, it can enable improvements in technologies, and on regular public campaigns to increase education in important sustainable matters.

Material Flow Analysis (MFA) and waste characterizations for formal and informal performance indicators in Tandil, Argentina: Decision-making implications

In cities, the achievement of waste-related legal requirements and the main drivers of Integrated Sustainable Waste Management (ISWM) need adequate indicators and adaptable-to-case tools and strategies. In this work, we combine Material Flow Analysis (MFA) and waste characterizations to develop a mass balance table to design, calculate and analyse indicators related to the formal and informal waste sub-circuits of Tandil, a medium-sized city of the Buenos Aires province (Argentina). Results show that global recovery is very low (2.3% ± 0.16) and mainly driven by the Informal Recovery Sector (IRS). Also, the IRS strategy is more effective, recovering 40% ± 8.0 of its targeted materials from non-household sources. Regarding each material recovery performance, results show significant differences. For paper and board, recovery exceeds 20%. For HDPE, Tetra brik and Ferrous Metals are lower than 1%. In the case of PET and Glass, 9.6 and 9.0% of what is generated in households is recovered, respectively. However, the global recovery rate of each material is different: 2.9% ± 0.4 for PET and 5.5% ± 1.4 for Glass. Our research show that strategies in place are insufficient regarding legislation in force. Even a hypothetically 100% effectiveness in them will account only for 20.9% ± 2.1 of global recovery. Addressing organic waste, therefore, is imperative. Considering the current province law provision of final disposal diversion, accounting for the work of the IRS is key because they recover more waste than the official strategy. Regarding open dumps eradication, we estimate that up to 17% of generated waste is incorrectly final disposed through private skips illegally dumped. A tracking system for skips could avoid this situation.

‘Wasteaware’ Indicators: an Assessment of the Current Solid Waste Management System in Lahore, Pakistan

The present status of solid waste management reviewed into this article based in Lahore, Pakistan. Following UN-Habitat city profiling with involved systematic quantitative, qualitative assessment, governance features of the present waste management includes in and shows the present system, waste collection, transportation is the main concentration and producing 74,000 tons year-1 of organic compost. Lahore waste management system (LWMC) is low in their target market consulted in decision making (inclusivity) and bad performance (governance features). Formal waste management system having backward of the informal system, which is absolutely inconsistent with current waste management systems. Watchful arranging and organization proposed here to reduce the trouble by integrating informal waste management system into formal waste management system for shared advantages. The integrated sustainable waste management (ISWM) indicators used for different levels of income class and LWMC performance in Lahore. Recommendation builds for the public awareness for recycling and to make the integrating informal sector sustainable system and fill the historical data gap.

A Study and Factor Identification of Municipal Solid Waste Management in Mexico City

Mexico City generates 12 thousand tons of Municipal Solid Waste (MSW) per day, which places it as one of the cities that produces the most MSW in the world. However, the treatments used in the city are not enough for recycling materials and organics valorization of at least 45% of the MSW, which is the minimum for a medium-high-income city. To put in a global context the deficiency in Municipal Solid Waste Management (MSWM) in Mexico City and evaluate the policies that have been implemented thus far, Wasteaware benchmark Indicators for Integrated Sustainable Waste Management (ISWM) were used to obtain a desired profile for the comprehensive MSWM in Mexico City. The Wasteaware Benchmark Indicators have been tested in more than 50 cities around the world. The results showed that in Mexico City, certain aspects of governance present the most considerable delay and, at the same time, that there are certain areas of opportunity to improve the efficiency of MSWM in its physical aspects, such as collection systems or treatment services.

Integrated Sustainable Waste Management in Tourism Markets: The Case of Bali

The analysis presented here will apply the integrated sustainable waste management (ISWM) model to Bali’s tourism industry to contemplate the viability of introducing to the island tech-based infrastructure, specifically solar-powered waste compactors, in low- to medium-density areas. The current system of waste management in Bali reveals a lack of cooperation among its stakeholders; hotels and luxury developers are using non-biodegradable materials at a massive scale—the proper disposal of which the local residents are unfamiliar with—and much of this waste ends up in illegal dumps. This system illustrates how inherently unsustainable the tourism industry is in general and especially in areas lacking consistent government supervision. This article will explore how a culture-shift perspective, organisation of cooperative entities, multi-stakeholder governance and integration of tech-based solutions can help alleviate current pressure on the waste system in Bali.

Electronic Waste in China, Japan, and Vietnam: A Comparative Analysis of Waste Management Strategies

Abstract This paper comparatively analyses the e-waste sector in China, Japan, and Vietnam by examining progress towards the international best practice model of Integrated Sustainable Waste Management (ISWM) within each country. Through three distinct, yet interdependent dimensions of ISWM (stakeholders, waste system elements, and sustainability aspects), similarities and differences between the three East Asian countries are identified. The analysis shows that the e-waste management approaches differ substantially. The Vietnamese e-waste management approach is least consistent with the ISWM framework, while Japan complies the most with the ideals of the model and Chinese progress towards ISWM is mostly located between the two countries. However, a substantial proportion of Japanese e-waste is exported to developing countries in an uncontrolled manner. The analysis further suggests that the state of development and national characteristics have a significant impact on how the three countries approach e-waste management. In particular, the central role of the informal e-waste sectors in China and Vietnam poses a challenge to the establishment of an effective integrated sustainable e-waste management system. In light of the transnational flow of e-waste in the region, only joint actions will lead to long-term solutions to the increasing threat of e-waste to the environment and human health.

A tale of five cities: Using recycling frameworks to analyse inclusive recycling performance.

'Recycling' is a source of much confusion, particularly when comparing solid waste systems in high-income countries with those in low- and middle-income countries. Few analysts can explain why the performance and structure of recycling appears to be so different in rich countries from poor ones, nor why well-meaning efforts to implement recycling so often fail. The analysis of policy drivers, and the Integrated Sustainable Waste Management (ISWM) framework, come close to an explanation.This article builds on these earlier works, focusing in on five cities profiled in the 2010 UN-Habitat publication (Scheinberg A, Wilson DC and Rodic L (2010) Solid Waste Management in the World's Cities. UN-Habitat's Third Global Report on the State of Water and Sanitation in the World's Cities. Newcastle-on-Tyne, UK: Earthscan Publications). Data from these cities and others provides the basis for developing a new tool to analyse inclusive recycling performance. The points of departure are the institutional and economic relationships between the service chain, the public obligation to remove waste, pollution, and other forms of disvalue, and the value chain, a system of private enterprises trading valuable materials and providing markets for recyclables. The methodological innovation is to use flows of materials and money as indicators of institutional relationships, and is an extension of process flow diagramming.The authors are using the term 'recycling framework analysis' to describe this new form of institutional analysis. The diagrams increase our understanding of the factors that contribute to high-performance inclusive recycling. By focusing on institutional relationships, the article seeks to improve analysis, planning, and ultimately, outcomes, of recycling interventions.

‘Wasteaware’ benchmark indicators for integrated sustainable waste management in cities

This paper addresses a major problem in international solid waste management, which is twofold: a lack of data, and a lack of consistent data to allow comparison between cities. The paper presents an indicator set for integrated sustainable waste management (ISWM) in cities both North and South, to allow benchmarking of a city’s performance, comparing cities and monitoring developments over time. It builds on pioneering work for UN-Habitat’s solid waste management in the World’s cities. The comprehensive analytical framework of a city’s solid waste management system is divided into two overlapping ‘triangles’ – one comprising the three physical components, i.e. collection, recycling, and disposal, and the other comprising three governance aspects, i.e. inclusivity; financial sustainability; and sound institutions and proactive policies. The indicator set includes essential quantitative indicators as well as qualitative composite indicators. This updated and revised ‘Wasteaware’ set of ISWM benchmark indicators is the cumulative result of testing various prototypes in more than 50 cities around the world. This experience confirms the utility of indicators in allowing comprehensive performance measurement and comparison of both ‘hard’ physical components and ‘soft’ governance aspects; and in prioritising ‘next steps’ in developing a city’s solid waste management system, by identifying both local strengths that can be built on and weak points to be addressed. The Wasteaware ISWM indicators are applicable to a broad range of cities with very different levels of income and solid waste management practices. Their wide application as a standard methodology will help to fill the historical data gap.

Waste management and recycling in the former Soviet Union: The City of Bishkek, Kyrgyz Republic (Kyrgyzstan)

The UN-Habitat Integrated Sustainable Waste Management (ISWM) benchmarking methodology was applied to profile the physical and governance features of municipal solid waste (MSW) management in the former Soviet Union city of Bishkek, capital of the Kyrgyz Republic. Most of the ISWM indicators were in the expected range for a low-income city when compared with 20 reference cities. Approximately 240,000 t yr(-1) of MSW is generated in Bishkek (equivalent to 200 kg capita(-1) yr(-1)); collection coverage is over 80% and 90% of waste disposed goes to semi-controlled sites operating with minimal environmental standards. The waste composition was a distinctive feature, with relatively high paper content (20-27% wt.) and intermediate organic content (30-40% wt.). The study provides the first quantitative estimates of informal sector recycling, which is currently unrecognised by the city authorities. Approximately 18% wt. of generated MSW is recycled, representing an estimated annual saving to the city authorities of US$0.7-1.1 million in avoided collection/disposal costs. The waste management system is controlled by a centralised municipal waste enterprise (Tazalyk); therefore, institutional coherence is high relative to lower-middle and low-income cities. However, performance on other governance factors, such as inclusivity and financial sustainability, is variable. Future priorities in Bishkek include extending collection to unserved communities; improving landfill standards; increasing recycling rates through informal sector cooperation; improving data availability; and engaging all stakeholders in waste management strategy decisions. Extending the scope and flexibility of the ISWM protocol is recommended to better represent the variation in conditions that occur in waste management systems in practice.
