Integrated municipal solid waste management using ArcGIS tools: A case of akaki-kality sub-city, addis ababa, ethiopia.

This study aimed to optimize the solid waste collection and transportation system using ArcGIS Network Analyst and location-allocation tools. The generated solid waste was characterized by proximate analysis. The generation rate and composition were determined according to standard methods. The average solid waste generation rates for households, commercial sites, institutions, and recreational places were 0.48kg/c/day, 15.03kg/fac/day, 9.32kg/fac/day, and 22.8kg/fac/day, respectively. The estimated total generation rate of the sub-city is 207,004.03kg/day and 712.13 m3/day as discarded base. Composition analysis revealed that food waste is the major component of municipal solid waste, with estimated weight and volume of 134,696.08kg and 299.46 m3, respectively. Proximate analysis indicated that food and textile wastes have relatively high moisture content and fixed carbon. Candidate pre-collection bin allocations were optimized based on factors such as road network, distribution of solid waste generators, and existing temporary dumping sites, resulting in 1052 potential bin locations. Transfer station allocation was optimized by considering land use-land cover, slope, and geology. Twelve transfer routes and four transport routes were established to efficiently serve the bins and final waste destinations. In conclusion, the study demonstrates that ArcGIS Network Analyst and location-allocation tools can effectively optimize the municipal solid waste collection and transportation system, providing a robust framework for improving waste management efficiency. However, further research is recommended to validate these findings through field application.

A Quantitative Assessment Approach to Implement Pneumatic Waste Collection System Using a New Expert Decision Matrix Related to UN SDGs

An innovative decision matrix has been developed to guide the selection and implementation of Pneumatic Urban Solid Waste Collection Systems (PUSWCS) in smart city projects. This study comprehensively collects and analyzes data on the advantages and disadvantages of pneumatic collection systems from technical, economic, and social perspectives. A decision-making tool was created to address the complexities of evaluating the desirability of incorporating PUSWCS in municipalities or specific areas, using a holistic approach. The tool assesses the technical, economic, and social feasibility of implementing PUSWCS, aligning it with the United Nations’ Sustainable Development Goals (SDGs). Specific variables are measured to assess compliance with the SDGs, distinguishing technical aspects from economic and social aspects. The methodology includes surveys of system users and technicians, expert assessments, and the development of a decision matrix that cross-references study variables and SDGs. The matrix assigns numerical values to the Magnitude (M) and Impact (I) of each variable, enabling quantitative interpretation. This holistic approach accommodates the complexities of waste management and diverse stakeholder perspectives. The results demonstrate the matrix’s effectiveness in accurately assessing the desirability of implementing PUSWCS. This confirms the matrix’s ability to optimally integrate with innovative smart city concepts and align with long-term sustainability goals. The study concludes that the design of the decision matrix allows the collection of information from experts, users, and stakeholders about economic, social, and environmental variables and relates them to the SDGs, to obtain a numerical result that allows to decide whether in a given urban environment it is advisable to implement a PUSWCS.

Study of the dynamics of urban solid waste management considering the characterization of the collection routes in the municipality of Huatusco, Veracruz

This study was conducted in the municipality of Huatusco de Chicuellar, in the state of Veracruz, to characterize the urban solid waste collection system, and to identify the pertinent logistical indicators to propose and analyze possible strategies that contribute to the redesign of the current collection system. For the development of the study, sampling was carried out to identify the micro waste collection routes with the help of technological tools such as the Global Positioning System, known as GPS, and they were represented graphically on the Google Earth platform. Through the evaluation of the collection routes, the main logistical indicators were identified, such as the mileage traveled on the routes, diesel consumption and the cost of final waste disposal. The information obtained in the characterization of the routes, in addition to other data obtained in previous studies of MSW generation and composition, carried out in the city, made it possible to develop a dynamic model with which it is possible to present an improvement scenario that consists of separating waste at the source (in families) and to observe the economic impact that this action can have for the municipality.

Auralocular Autowastebin using IoT

As human intelligence continues to advance, so too does the sophistication of our everyday surroundings. The concept of Smart Cities has given rise to a demand for intelligent waste management solutions. Enter the concept of Smart Dustbins, tailored for deployment in Smart buildings, educational institutions, healthcare facilities, and public transit hubs. The Smart Dustbin represents an enhancement of the conventional waste receptacle, elevating it to a smart status through the integration of cutting-edge sensors and logical systems. The innovation behind Smart Dustbins lies in their ability to transform ordinary trash bins into intelligent entities. This is achieved by employing ultrasonic sensors for precise garbage level detection, coupled with a GSM module for real-time status updates to users. When a Smart Dustbin reaches full capacity, it triggers an automated Solid Waste Collection system to take action. One common issue with inadequately maintained traditional dustbins is the unsightly spillage of garbage in their vicinity. Such neglect can foster the proliferation of disease-carrying insects like mosquitoes, flies, bees, and driver ants. Moreover, the environment surrounding these bins can contribute to elevated levels of air pollution. Airborne pollutants stemming from a neglected dustbin can harbor harmful bacteria and viruses, posing severe health risks to humans. In conclusion, the integration of Smart Dustbins not only enhances waste management efficiency but also plays a crucial role in promoting cleaner and healthier urban environments.

URBAN DEVELOPMENT AND WASTE MANAGEMENT PLANNING IN KABUL NEW CITY, AFGHANISTAN: A CASE STUDY

The municipal solid waste collection system and services of existing Kabul City are not acceptable socially, economically, and environmentally. This study was carried out in 2020–2021 for the Phase-1 area of Kabul New City (KNC). The study aims to analyze different MSWCSS for the KNC area and choose the best option during the planning stage. The average incremental cost for different collection systems was determined, and the results show that the total annualized cost (AN) of the proposed waste collection system (PWCS) is 855.3699 AFN/tonne, while the total operation and maintenance cost (OP) is 577.1235 AFN/tonne. The AN and OP of the stand-alone underground waste collection system (SAUWCS), tailored collection point system, traditional (prevailed) system, and alley waste collection system (AWCS) are 911.3032 AFN/tonne and 499.9017AFN/tonne, 1,681.762 AFN/tonne and 1,267.28 AFN/tonne, 308.9254 AFN/tonne and 186.3363 AFN/tonne, and 716.7706 AFN/tonne and 410.5375 AFN/tonne, respectively. The social and environmental analysis for the PWCS, SAUWCS, existing system, and AWCS obtained scores of 19, 29, -6, 17, and -5, respectively. From the cost-benefit analysis, it has been proposed that for the PWCS of low-rise residential areas, three wheelie bins of different colors will be provided to each housing unit. The total costs per tonne of solid waste for the PWCS, SAUWCS, TCPS, and traditional system are 2,832.1952, 3,638.137205, 3,888.6272, 751.45984, and 1,975.8152, respectively. For the PWCS of residential areas, chute waste collection systems are planned for high-rise apartment buildings and SAUWCSs are planned in commercial areas.

Managing Municipal Solid Waste Issues; Sources, Composition, Disposal, Recycling, and Volarization, Chililabombwe District, Zambia

Solid waste continues to pose important challenges to our environment on a daily basis. Insufficient solid waste management systems and equipment have contributed to the alteration to the ecosystems, including water, air, and soil pollution that infringes on the health of the general public that is associated with health ailments like cholera and other food and water borne diseases. Chililabombwe district’s face has continued to be dented with the unkempt environment with littered solid waste that has become a stinging and widespread challenge, especially in the urban areas of the district. Solid waste (SW) collection and working disposal systems are the major problems of the urban environment in most developing countries worldwide. MSW management solutions are financially dependable for the technical viable, socially inclement, and legally accepted. Solid waste management remained the biggest challenge that all the local authorities in Zambia and many developing countries in Africa. Commercialization or valorization of organic food waste was one of the important research areas that could combat the increased solid waste in the environmental causing environmental degradation. The objective of this study was to address matters that would respond positively to the waste management crisis in the district. As waste continues to be accumulated, with its high generation, more technologies are sought in the area of treatment and exploitation of organic and municipal waste through composting and anaerobic digestion in the management of waste. The lack of technologies and machinery has equally downplayed the essence of waste management in the Chililabombwe district.

Life Cycle Analysis and Cost–Benefit Assessment of the Waste Collection System in Anyama, Cote d’Ivoire

Municipal solid waste collection system in Anyama is in a critical state and is compounded by high population density. Household residents need about 30 minutes’ walk to the designated waste collection point. Waste is dumped openly along the roadside, which serves as breeding grounds for chronic diseases, malaria, diarrhea, and acute respiratory disease. Could the perception and attitude of residents change if the distance between their homes and the collection points is reduced? This study evaluated the current waste management system in Anyama. Life Cycle Assessment (LCA) and cost–benefit analysis were conducted on four different waste collection scenarios, to propose an alternative, feasible, and integrated solid waste management system. Results showed that the kerbside recycling scenario has the highest benefit (5.8 billion CFA) compared to its cost (1.9 billion CFA), proving to be more economically sustainable. In environmental terms, the kerbside recycling scenario emitted lower emissions such as global warming potential (GWP 4967 tons) and carbon dioxide (CO2eq 550 tons). The kerbside recycling obviously had the highest potential for recycling and thus is more environmentally sustainable. Therefore, the kerbside scenario is the most suitable and recommended policy that should be adopted and implemented in Anyama. We recommend the introduction of waste banks specifically for recyclable waste and the setting up of more kerbside collection points in order to reduce the distance from households to collection points, thus improving residents’ attitude towards effective waste disposal.

Cloud-Edge-Terminal-Based Synchronized Decision-Making and Control System for Municipal Solid Waste Collection and Transportation

Due to dynamics caused by factors such as random collection and transportation requirements, vehicle failures, and traffic jams, it is difficult to implement regular waste collection and transportation schemes effectively. A challenge for the stable operation of the municipal solid waste collection and transportation (MSWCT) system is how to obtain the whole process data in real time, dynamically judge the process control requirements, and effectively promote the synchronization operation between multiple systems. Based on this situation, this study proposes a cloud-edge-terminal-based synchronization decision-making and control system for MSWCT. First, smart terminals and edge computing devices are deployed at key nodes of MSWCT for real-time collection and edge computing analysis of the whole process data. Second, we propose a collaborative analysis and distributed decision-making method based on the cloud-edge-terminal multi-level computing architecture. Finally, a “three-level and two-stage” synchronization decision-making mechanism for the MSWCT system is established, which enables the synchronization operation between various subsystems. With a real-world application case, the efficiency and effectiveness of the proposed decision-making and control system are evaluated based on real data of changes in fleet capacity and transportation costs.

Solid Waste Management and Challenges under War Situation Case Study lataki City- Syria

Wars have a particularly dangerous impact on solid waste management. Given the relatively long period of conflict in Syria, the collapse of environmental infrastructure and services has caused serious damage to the health of civilians. This conflict has caused some kind of environmental threat due to environmental pollution caused by debris, solid waste, and pollution from damaged industries and remnants of munitions that cause immediate and long-term threats to civilians and the environment. Solid waste treatment and disposal in Syria are not in the first place in importance, because the collection and transport of solid waste devour most of the city municipality’s budget. Because of the internal migration during the war in Syria, increases the populations in latakia city which increase solid waste amount. This leads the need to increase containers numbers in city regions and re-manage its spatial distribution by using geographic information systems (GIS). Therefore it was important to conduct this study to analyze the existing solid waste management regarding the collection system situation in Latakia city. The main purpose of this study is to improve the solid waste collection system (2018-2020) by covering all city-areas. The disposal of solid waste of the most important environmental issues of contemporary, as a result of increasing population and what has been associated with the change in the patterns and lifestyles and increased consumption, this increases the amount of waste produced, especially in cities, where the estimated amount of solid waste produced daily in the city of Latakia, is 840 tons. Thus became an urgent need to follow the techniques in the management of solid waste in all stages to public health and environmental protection. This study summarized the estimation of the amount and characteristics of solid waste and the methods used to collect and analyze the spatial distribution of the waste collection containers in all areas of the Latakia city and better planning commensurate with its population and the amount of waste produced using GIS technology.

Connectivity of vegetation diversity, carbon stock, and peat depth in peatland ecosystems

BACKGROUND AND OBJECTIVES: Prior to the COVID-19 pandemic, Hoi An City was one of the most famous tourist destinations in the world. This led to a rapid increase in solid waste generation, leading to problems and challenges in solid waste collection and management. This problem is also being experienced by other developing countries of the world. Despite the existence of established waste management strategies, targets set for the collection of recyclable waste have not been met. This study introduces solutions to the problems and challenges faced by the waste management sector in Hoi An city and other developing countries. This study aimed to i) optimize the map of the recovery recycling stations in an urban community, ii) develop an effective solid waste collection system, and iii) provide management tools to enhance recycling activities, contributing to improving waste management in Hoi An city.METHODS: The RRSs were integrated into a solid waste collection system in the urban communities of Hoi An City, were conducted through location-allocation analysis in a geographic information system environment. Routing problems of carts were solved in the combination of the rescheduling of existing solid waste collection activities in the study site. The economic evaluation by scenarios was also calculated for ten years to assess the feasibility of scenarios.FINDINGS: Thirty-four locations were identified and optimized to accommodate the RRSs and new collection routes. The distances travelled and working time increased in proportion to the increase in waste separation effectiveness.

FACTORS AFFECTING CITIZENS’ INTENTION TO CONTINUE USING THE REWARDING SOLID-WASTE COLLECTION MOBILE APPS IN TEHRAN, IRAN

Abstract. Despite technological advances in waste recycling and management, many developing countries, including Iran, are still in the early stages of this process: the segregation and collection of recyclable waste. In this regard, to increase citizens' coope ration in household waste segregation, a rewarding solid-waste collection system has been established in the metropolises of Iran. In such circumstances, it is evident that maintaining the continued use of citizens without compromising their satisfaction has become an essential concern in the development of a sustainable waste collection and recycling system in Iran. For this reason, the present study tries to investigate the factors affecting citizens' continuous intention to use the rewarding solid-waste collection (RSWC) mobile apps in Tehran (the capital of Iran). In this regard, first, the conceptual model of the research is obtained by combining the widely used ECM model with D&M’s IS success model. Then, the questionnaire designed based on previous studies was provided to the citizens, and out of a total of 373 completed questionnaires, by removing the incomplete ones, 302 questionnaires were finally analysed. A partial least squares (PLS) analysis based SEM using SmartPLS was performed to assess the model and verify hypotheses. Results show that various variables significantly influence users’ continuous intention to use RSWC mobile apps. Meanwhile, RSWC mobile apps should improve their platform quality and rewarding system, strengthen their content quantity, and ensure the consistency between their service and citizens’ satisfaction.

Optimization of municipal solid waste collection routes in a Latin-American context

ABSTRACT Latin-American cities need efficient municipal solid waste (MSW) collection systems, specifically in municipalities with fast urbanization. Poor logistics in collection routes is one of the causes of inefficient MSW management. A strategy for designing the MSW collection routes, considering an environmental and economic analysis, was developed and tested in the Metropolitan Area of Monterrey (MMA), one of the cities with the highest urban and economic development in Mexico. Life cycle assessment and costs analysis were performed to evaluate archetypal routes’ environmental and economic impact in the current MSW collection system. The assessment of the environmental impact was realized through midpoint indicators of the ReCiPe 2008 method. The mathematical model describing the collection routes was developed using actual data from the MSW collection system in MMA, optimized by the Traveling Salesman Problem (TSP), and solved in RStudio. This study shows a reduction of between 9 and 20% of greenhouse gas emissions and distance covered in current collection stages, respectively. The results also demonstrate the influence of road direction, collection-truck efficiency, and traffic load in different stage on the environmental and economic impacts of the collection routes. A life cycle inventory, with realistic inputs and outputs of the MSW collection system, was developed. These inventories are scarce in Mexico and Latin America; their development helps designing cleaner MSW collection systems. Implications: The optimization of urban solid waste collection systems is a strategy to reduce costs and environmental impacts, considering factors such as distance or fuel consumption. However, mathematical models within the optimization require detailed information of the road network to achieve reliable results. In this context, Latin America shows difficulties in increasing its collection systems’ efficiency due to economic constraints and limited access to information from locals governments. The use of geographic information systems has been shown to collect real data on a city’s roads. This work aims to propose a strategy for designing urban solid waste collection routes with the least environmental and economic impacts through an optimization strategy that considers the road network’s real-time data, added to an environmental analysis developed with a life cycle assessment approach. We believe that our results could help the design of urban solid waste collection systems for cities with Latin American characteristics. Additionally, an inventory of specific inputs and emissions for waste collection in this type of city will be generated, supporting future sustainable management strategies.

Household Generated Solid Waste Collection System Management Using Arcgis: a Case of Jimma Town, Southwestern Ethiopia

Proper management of solid waste collection is one of the challenges in the urban areas of developing countries like Jimma town. Therefore, this study aims to assess the municipal solid waste collection system in Jimma town using geographical information system, GIS, techniques. Data used were digital elivation model, DEM, river shapefile, and coordinates of the locations of municipal solid waste, MSW, collection containers and open disposal site. Distances of the locations of existing MSW collection bins from the surface water, the contour lines and flow directions of areas around the existing Qofe Open Dump Site were evaluated. The findings of the study indicate that there was one waste container that was allocated in a 20 m buffer distance from the river. The solid waste collection bins in the town were not evenly allocated. The allocated waste collection containers covered only 12.32% of the total area of the town. There were about 34(51.52%) shortage of MSW collection bins in the town. The municipality should transfer collection bins placed in the river buffer zone of 20 m to other suitable locations. Unserved areas of the town should have waste collection containers after further detail investigation. Water sources near the open disposal site need to be regularly monitored for quality degradation.

Design of a Municipal Solid Waste Collection System in Situations with a Lack of Resources: Nikki (Benin), a Case in Africa

Waste collection is one of the most important public services in a town. However, waste collection has not been effectively implemented in some places due to the lack of economic and management resources. The waste is placed in inappropriate sites with the consequent risks of pollution and unhealthy conditions for the inhabitants. Therefore, establishing a municipal solid waste collection plan can be complicated. The methodologies and techniques that work in countries with medium and high income levels cannot be extrapolated to others with low income level because the boundary conditions are widely different. The aim of this paper is to design a municipal solid waste collection system adapted to this type of situation where not much money can be invested and where data are limited. In these cases, municipalities need to use their existing resources effectively. This paper offers a methodology for these cases as well as a case study. The first step was to gather information about the type and amount of waste generated and the characteristics of the town. The second step was to propose the location of the bins and, finally, the waste collection routes. With all these data, the technical and human resources were set. The methodology used was validated in a real case, the town of Nikki (Benin) in Africa. The collection of three waste fractions was designed with the actual resources of the city in order to offer a realistic implementation. Similar situations can be found around the world, and this case study can be used as an example to improve the waste management practices in some places with low resources.

Solid Waste Collection System in Tourism Destination-The Status, Problems and Challenges

Solid waste collection system (SWCS) plays an extremely important role in solid waste management system (SWMS). Optimization on SWCS have always been a primary mission of SWM towards sustainability. Hoi An city (HAC) is a tourist attraction in the central of Vietnam with omnipresence of tourism activities especially in tourism destination (TD). As a result, optimization of SWCS towards sustainability is crucial for TD of HAC. This study aimed to offer understandings on the current SWCS. This study was conducted with GPS (Global Positioning System) logger and QGIS 3.4 to collect and analyze data of existing SWCS. Results showed that, four modes of transportation were used for solid waste collection activities (SWCA) with almost all of sources of WG in the morning. Largest figures for total number of route (29) and amount of waste collected by carts (19.6m3) were illustrated in the morning shift (MS). Illegal solid waste collection (SWC) accounted for about 10 % of total amount of waste collected by carts. Forklift trucks were the final disposal of all SWCA in TD. Current waste gathering (WG) practices indirectly damaged the tourism activities while the improper implementation of selective waste collection at source hindered the efficiency of SWCS in TD. This study made a contribution as a scientific base for optimization and administration of SWCS.
