Urbanisation is a growing issue in Longleng. So are the consequent solid waste generation and its management challenges. Population growth has a positive impact on urbanization process. This article is intended to explain the common problems facing public services today and the challenges faced by both the urban planners and the government. The paper reviews an overview of solid waste management generation in urban Longleng. Solid waste management which is already an immense task in urban Longleng is going to be more difficult with the expansion of urbanization, increase in consumerism and changing life style. The result shows that residential (59.5%), commercial (20%), institutional (16%), biomedical wastes (0.30%), construction and demolition (4.2%) contribute to solid waste generation. The current practices of dumping waste materials in urban areas have shaped serious environmental and public problems. Financial resources constraints, institutional policies weaknesses, and public indifference towards solid waste have made this situation worse. This research article evaluates the current practices prevalent to deal with this solid waste and problems associated with it. It also provides the measures to deal with this waste in a healthy and environmental manner so that it may prove a resource instead of waste. The results of this study will be of immense benefit for urban-related studies in small towns as well as for the urban planners in the district.

One of the main environmental issues to address in large urban areas is the ever-increasing generation of municipal solid waste (MSW) and the need to manage it properly. Despite significant efforts having been made to implement comprehensive solid waste management systems, current management methods often do not provide sustainable alternatives which ensure the reduction of solid waste generation. This paper presents an analytical methodology that employs a combination of geographic information system techniques (GIS) along with statistical and numerical optimization methods to evaluate solid waste generation in large urban areas. The methodology was successfully applied to evaluate MSW generation in different exclusive service areas (ASES) of the city of Bogotá (Colombia). The results of the analysis on the solid waste generation data in each collection area in terms of its socioeconomic level are presented below. These socioeconomic levels are explained by defining different strata in terms of their purchasing power. The results demonstrate the usefulness of these GIS and numerical optimization techniques as a valuable complementary tool to analyze and design efficient and sustainable solid waste management systems.

Solid waste management in any large urban city like Lahore requires special disposal measures. In thisregard, Lakhodair landfill and Mehmood booti dump sites collect and handle major bulk of all the solid waste comingfrom ten towns of Lahore, with the city’s waste generation rate of being 0.84kg/capita per day. Spatial expanse of boththe sites was calculated in Arc GIS 10.3 system. The findings clearly showed that the extent of both these dump siteshad increased during 2006-2016 due to an enormous rise in solid waste generation. During 2006, the area of MehmoodBooti dump site and Lakhodair Landfill site was only 15 hectares and 17 hectares respectively. By 2016, this area hadincreased to 32 hectares and 52 hectares respectively. The mapping of these two sites can help in future researchesbased on investigating the disease patterns among people residing around these sites and by determining methaneemissions in the study area.

Purpose Due to the increasing population and prosperity, the generation rate of municipal solid waste (MSW) has increased significantly, resulting in serious problems on public health and the environment. Every single person in the world is affected by the municipal solid waste management (MSWM) issue. MSWM is reaching a critical level in almost all areas of the world and seeking the development of MSW strategies for a sustainable environment. This paper aims to present the existing global status of MSW generation, composition, management and related problems. Design/methodology/approach A total of 59 developed and developing countries have been grouped based on their gross national income to compare the status of various MSWM technologies among them. A total of 19 selection criteria have been discussed to select appropriate MSWM technology(s) for a city/town, which affects their applicability, operational suitability and performance. All risks and challenges arising during the life cycle of the waste to energy (WtE) project have also been discussed. This paper also gives a comparative overview of different globally accepted MSWM technologies and the present market growth of all WtE technologies. Findings It was found that most developed countries have effectively implemented the solid waste management (SWM) hierarchy and are now focusing heavily on reducing, reusing and recycling of MSW. On the other hand, SWM has become very serious in low-income and low-middle-income countries because most of the MSW openly dumps and most countries are dependent on inadequate waste infrastructure and the informal sector. There are also some other major challenges related to effective waste policies, availability of funds, appropriate technology selection and adequacy of trained people. This study clears the picture of MSW generation, composition, management strategies and policies at the worldwide context. This manuscript could be valuable for all nations around the world where effective MSWM has not yet been implemented. Originality/value This study clears the picture of solid waste generation, composition, management strategies and policies at the worldwide context. This manuscript could be valuable for all nations around the world where effective MSWM has not yet been implemented. In this study, no data was generated. All supporting data were obtained from previously published papers in journals, the outcomes of the international conferences and published reports by government organizations.

Solid waste problem is happen in many big city, such as Surabaya City. Jemur Wonosari which is participant in Surabaya Green and Clean (SGC) program also have waste management problems. When SGC was conducted, solid waste management is good. However, after the program finished, solid waste management facilities was neglected. In this research we measured solid waste measurement in waste generation and composition from domestic and non-domestic. Also to survey the level of community participation in manage solid waste. The design is quantitative research, data getting from measurement of waste generation and composition also question data to know community participation level in waste management which influenced by internal factors (knowledge, motivation, and environment attitude).The result of research, waste from people in a day is 0,093 kg/person/day. The result of solid waste generation which produced by the community is about 2054,37 kg/day. Waste composition which dominated by food waste, it’s about 43,3%. From the X2 test explain that there is a relation between knowledge, motivation, and environment attitude to community participation and between community participation to solid waste management. The community need to improve composting activities to minimize waste and rise up community participation.

Traditional markets are commercial areas that produce household-type solid waste so that the generation, composition, and the characteristics of the solid waste in Kepanjen Market will be different. This research is related to the reduction potential to improve solid waste management with the aim of determining the generation, composition, characteristics, collection and the transportation of the solid waste. The data used in this study include operational technical solid waste data, as well as secondary data such as area, number of traders, solid waste management resources, collection facilities, transportation routes, supporting maps. Solid waste generation calculation uses load-count analysis method. Calculation of solid waste composition uses the crossroad method. Calculation of physical characteristics includes specific gravity of solid waste. Calculation of transportation of solid waste uses the Hauled Container System method. Mass balance is analyzed using recovery factor values. The results of the analysis show that the solid waste generation average is 2.94 m3/day, with a specific gravity of 190.03 kg/m3. The highest composition of solid waste is food solid waste by 28.67% and vegetable and fruit solid waste by 22.67%. These components can be used as compost raw materials. The potential reduction with the mass balance method shows that the residue is 201.49 kg/day, reduction scenario can reduce solid waste by 36.06% of the total load that must be transported to the Final Processing Site. The solid waste transport result with the capacity/size of 6-10 m3 of a transport vehicle (arm roll truck) shows that the effective working hours for 8 hours can pick up the solid waste in 1 trip, and the transport fleet can serve other markets.

This chapter aims to describe the status and challenges of waste management (WM) in Rwanda. Currently, waste is managed by the Ministry of Local Government, with the participation of private companies which are only in charge of waste collection. In the city of Kigali, waste is managed by the city of Kigali whereas in other four remaining provinces waste is managed by the districts. Implementation of waste management policy is carried out by a government-owned company called Water and Sanitation Corporation (WASAC) Ltd. The per capita solid waste generation rate in the city of Kigali is equal to 0.57 kg/person/day. A lot of legislations and regulations on WM are in place but their enforcement is weak. The Government of Rwanda should do more in terms of enforcing WM legislations and regulations.

One of the globally pertinent issues is to manage the wastes generated in an organized manner. Mitigating solid waste generation is important alongside efficient management of the generated wastes is paramount. Thus, recycling has emerged as a viable alternative. Solid Waste Management comprises steps like collection, transportation, and disposal, and in an efficient waste management process, it is essential to monitor and design each process scientifically. Disposal in landfills is a general practice however; owing to inefficient segregation before disposal the wastes are highly toxic with the potential to affect the hygiene of the earth. It is observed that half of the wastes disposed of are toxic and this underpins the importance of segregation before disposing of. Also, identification of appropriate sites for landfill development is important and it is preferred to build them in areas that are sparsely populated.

Solid waste management is a big challenge throughout the world. It is becoming more complicated with the increased globalization and worldwide urbanization. Solid waste monitoring and management depends on the solid waste generation and collection efficiency. Without an efficient collection system, improvement of the solid waste monitoring and management system is a difficult task. Thus, it is a big hindrance on the way of development of solid waste management and sustainable environment. This paper deals with a comprehensive survey on the solid waste generation and their collection efficiencies. From the rigorous review, it is observed that the existing methods and system, however, not reliable and intelligent enough to monitor and manage the increased level of solid waste. Accordingly, this review is being highlighted on the issues and challenges for future efficient solid collection systems. This review paper may guide the reader about the basics of solid waste generation and their collection process to facilitate the planning and design of a sustainable new system

Purpose – This paper examined the current status of municipal solid waste management across Nigeria. The core aspects covered are generation, characterization, collection, scavenging, open dumping, disposal and environmental implications of poor solid waste management. The purpose of this paper is to present a comprehensive overview of the current state of municipal solid waste management in Nigeria. Design/methodology/approach – This study was executed by a combination of an extensive literature search and field study. Solid waste generation rates for 31 Nigerian cities were obtained from literature. In addition, characteristics of municipal solid waste from 26 Nigerian cities were also obtained from literature. Other aspects such as characterization of solid waste obtained from final dumpsite and heavy metals accumulation in solid waste dumpsites were undertaken first hand. Findings – Solid waste generation rate was found to vary from 0.13 kg/capita/day in Ogbomosho to 0.71 kg/capita/day in Ado-Ekiti. Factors affecting solid waste generation rates were identified. Typically, food waste was found to constitute close to 50 percent of overall municipal solid waste in Nigerian cities. This study shows that the rate of generation of plastics, water proof materials and diapers has assumed an upward trend. Due to the dysfunctional state of many municipal waste management authorities, many cities have been overrun by open dumps. For instance, more than 50 percent of residents of Maiduguri in northern Nigeria and Ughelli in southern Nigeria dispose of their waste in open dumps. Indiscriminate disposal of waste has also resulted in the preponderance of toxic heavy metals in agricultural soils and consequent bioaccumulation in plants as well as groundwater contamination. Research limitations/implications – The main limitation of this research is municipal waste management authorities do not have relevant data. Hence, there was heavy reliance on published materials. The status of waste management in Nigeria is very deplorable and therefore poses serious threats to public and environmental health. There is urgent need for both government and individuals to adopt holistic and sustainable waste management strategies in order to safeguard public/environmental health. Practical implications – Findings from this paper can form a veritable resource for the formulation and implementation of sustainable municipal solid waste management framework and strategies in Nigeria. Originality/value – While most studies on municipal solid waste management in Nigeria are focussed on selected cities of interest, this particular study cuts across most cities of Nigeria in order to present a broader and holistic view of municipal solid waste management in Nigeria. The paper has also unraveled core municipal solid waste management challenges facing Nigerian cities.
