Abstract
Purpose
The purpose of this paper is to formulate frameworks for the drivers and barriers of integrated sustainable solid waste management (ISSWM) with reference to conditions prevailing in India.
Design/methodology/approach
A multi-phased approach was adopted in this paper to come up with the conceptual framework of the drivers and barriers of ISSWM. In the first phase, drivers and barriers of ISSWM were identified based on a systematic literature review process. In the second phase, 25 experts having 15 plus years of experience in the field of sustainable development and environmental management were consulted to get their opinion. Validation and understanding of the interrelationship among the selected drivers and barriers were done based on the insights from expert interviews. And in the final phase, structural self-interaction matrix and transitive links are defined based on the expert opinion to come up with the theoretical frameworks of drivers and barriers of ISSWM.
Findings
Findings reveal the importance to have a system view point approach by giving equal importance to social, environmental and economic pillars of sustainability along with the technology component to effectively and sustainably manage the solid waste disposal. Institutional effectiveness and the robust policy and frameworks are the two variables found to have the highest driving power. Poor social values and ethics, huge population and illiteracy are the three most critical barriers faced by developing nations in achieving the sustainability practices in the solid waste management. The proposed frameworks of drivers and barriers of ISSWM will definitely help policy makers to effectively manage the sustainable waste management practices for developing economies by focusing on the key variables listed out.
Research limitations/implications
One of the limitations is in the use of very limited sample size in the study. Another limitation is that total interpretive structural modeling fails to come up with the relative weightings of drivers and barriers used in the study. These limitations can be overcome by extending the research by using a semi-structured questionnaire survey with higher sample size for the empirical validation of the model.
Practical implications
This research will help to clearly understand the framework of drivers and barriers of variables and their hierarchical level based on the driving power and dependence. Since such articles focusing on the conceptual frameworks of drivers and barriers of ISSWM are found to be very scant, this paper will equally help academicians and waste management professionals to understand the concepts deeply, by getting answers to the fundamental questions of “what,” “why” and “how.” Developed framework of drivers explicitly shows the need to attain financial stability through the commercialization of the waste management initiatives, which will help to reduce burden on various governmental institutions. Commercialization opportunities will also help to have more successful start-up ventures in solid waste management domain that can provide improved employment opportunities and hygiene environment in the developing nations like India.
Originality/value
Based on the authors’ best knowledge, there is hardly any article that explicitly explains the conceptual frameworks of the drivers and barriers of ISSWM by considering the conditions prevailing in developing countries like India. And thus, this can be considered as one of the unique research attempts to build a clear conceptual framework of ISSWM. The study contributes significantly to the existing literature body by clearly interpreting the interrelationships and the driving power and dependence of variables of ISSWM.

Abstract
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.

Abstract
A systems perspective of waste management allows an integrated approach not only to the five basic functional elements of waste management itself (generation, reduction, collection, recycling, disposal), but to the problems arising at the interfaces with the management of energy, nature conservation, environmental protection, economic factors like unemployment and productivity, etc. This monograph separately describes present practices and the problems to be solved in each of the functional areas of waste management and at the important interfaces. Strategies for more efficient control are then proposed from a systems perspective. Systematic and objective means of solving problems become possible leading to optimal management and a positive contribution to economic development, not least through resource conservation. India is the particular context within which waste generation and management are discussed. In considering waste disposal techniques, special attention is given to sewage and radioactive wastes.

This paper aims to describe the present waste management scenario in the city of Allahabad listing the gaps in the waste management system.
Abstract
Purpose
This paper aims to describe the present waste management scenario in the city of Allahabad listing the gaps in the waste management system.
Design/methodology/approach
The research work was divided into three stages. The first stage was the collection of background data regarding municipal solid waste management systems such as waste generation, waste collection, treatment and disposal methods. The second stage involved data organization and data analysis. The third stage provided the conceptual framework that has been developed for MSW management, and finally a sustainable and suitable waste management option was provided for improving the MSW management in Allahabad.
Findings
The existing solid waste management approach in the city is highly unprofessional and lacking in scientific methodologies. There is neither proper collection nor proper treatment and disposal of waste. Most of the waste is dumped in low lying areas leading to pollution of land, air and water due to leachate generation.
Practical implications
There is need to develop a correct and detailed database of waste generation, collection and treatment system in various wards of Allahabad so that required manpower, equipments and other services can be estimated for designing a proper waste collection, treatment and disposal system. No site for engineered landfill has been identified as per the site selection criteria provided by Ministry of Environment and Forests, Government of India. The suggestions in this paper have been made on the basis of data collected, actual observations and analysis.
Originality/value
The work identifies the gap in the present solid waste management system of Allahabad City.

Abstract
Purpose
This study evaluates the quantity and composition of solid waste produce in secondary schools and assesses level of environmental consciousness and management activities. This is aimed for the present and future planning of high schools' environment as well as integrating the system into urban waste management.
Design/methodology/approach
This research used primary and secondary data to realize its purpose. Primary data was obtained through measurement of actual waste generation and questionnaire administration. Secondary data was the official information obtained on the schools selected. The primary data collected was analysed with descriptive statistical method such as percentage, mean cross measures of central tendency, frequency distribution and cross tabulation.
Findings
The study established that a total of 375.6 kg of solid waste is generated in the selected schools and daily per capita waste generation is 0.56 kg. Paper material is the waste component with the highest quantity and 88.5% of waste produced is recyclable. Thus, solid waste generated in secondary schools if carefully managed with suitable management options has potential for promoting circular economy and sustainable development. The paper recommends environmental education for stakeholders in secondary schools and waste segregation culture should be enforced in every secondary school.
Originality/value
The paper builds on the reasons for poor environmental quality in secondary schools in developing countries and revealed unscientific means by which resources are wasted and the environment is mismanaged through low understanding of solid waste.

Abstract
Purpose
The research objectives are as follows: to understand the situation of solid waste management in the Makham Tia Subdistrict Administrative Organization, Surat Thani Province, Thailand; identify the patterns in household waste generation and 3Rs behavior (recycle, reuse and reduce waste); and formulate sustainable municipal solid waste management guidelines.
Design/methodology/approach
This study aimed to propose the solution by using data analysis and a participatory research approach to set the guidelines for sustainable community waste management in a low-budget area. A survey of household behavior was done with questionnaires. Mixed clustering using the Gower coefficient was performed to assess the categorical socio-demographic variables along with the numeric variables related to the 3Rs behavior. The guidelines for waste management were generated based on the characteristics of the household groups.
Findings
The guidelines for waste management were generated based on the characteristics of the household groups. An appropriate practical plan for municipal solid waste management in Makham Tia Subdistrict was proposed in this work. The study showed that the guidelines were implemented and revised by members of the community, and this led to the development of sustainable community solid waste management for the future.
Originality/value
The goal of this study was to provide a solution for sustainable community waste management in a low-budget location by using data mining techniques and a participatory research approach. The study showed that the guidelines were implemented and revised by members of the community, and this led to the development of sustainable community solid waste management for the future.

Abstract
Environmental engineering is primarily concerned with the application of technology to the urgent tasks of cleaning up our environment. Its practitioners generally attempt to cope with the problems of streams and waterways polluted by sewage and industrial waste, oceans damaged by oil spills and sewage sludge dumpings, air polluted with noxious fumes and land abused by solid waste disposal. But that is not all that they do. The recent energy crisis has sharply brought into focus the need for alternate energy strategies, including energy extraction from solid waste. Under current estimates, the United States will produce approximately 340 million tons of solid waste by 1980. This is equivalent to one ton of solid waste per person per year. The most widely used methods of waste disposal right now are dumping, incineration and sanitary landfill. They are expensive and they cause pollution. Instead, solid waste can be burned to produce steam which can be used for heating or to generate electricity. It can also be converted to pyrolysis gas or oil, which can be stored or transported. It is from this standpoint that environmental engineering assumes considerable importance. A report which presents an overview of the state of the art in this area is the Resource Recovery from Municipal Solid Waste. Other pertinent guides include Energy from Solid Waste, Conversion of Refuse to Energy, Recycling and Reclaiming of Municipal Solid Wastes, Resource Recovery and Recycling Handbook of Industrial Wastes, and Wasteheat Management Guidebook. No project of this nature can be undertaken without government assistance. A description of the activities of the Federal Solid Waste Management Program is available from EPA's Solid Waste Recycling Projects: A National Directory.

Abstract
Purpose
This study aims to empirically investigate the relationship between corporate social responsibility (CSR) and sustainable management of wastes and effluents (SMWE) in Lagos Megacity.
Design/methodology/approach
The paper adopts a quantitative research method, specifically the use of a Web-survey technique for eliciting responses from a cross-section of companies affiliated to the Lagos Chambers of Commerce and Industry (LCCI). From a target population of 2,300 companies, a sample of 92 companies was drawn using the sample determination formula of Parten (1950). The 92 sampled companies were randomly administered Web-based questionnaires through their official emails. Finally, the 56 responses received from the participating companies (corresponding to 61 per cent response rate) were analysed electronically and the results presented using descriptive and inferential statistics.
Findings
The results show strong positive relationships between CSR and advocacy on waste and effluents (0.7), environmental impact response (0.7), environmental sustainability policy (0.6) and preventive negative impact (0.6) with P < 0.05. However, weak positive relationships exist between CSR and monitoring mechanisms (0.3) and adequacy of infrastructure for wastes and pollutants management (0.4). Overall, there is a significant positive relationship between CSR and sustainable management of solid wastes and effluents in the sampled companies in Lagos.
Research limitations/implications
The research is limited to Lagos Megacity because it is the industrial and commercial hub of Nigeria. Besides, there are several industrial associations in Lagos, but the selected association was the LCCI with 56 sampled companies.
Practical implications
The research supports and validates the theory of planned behaviour (TPB), which explicates that performance behaviour of organisations is influenced by the behavioural intention and behavioural control. However, behavioural intention of organisations may be carried out, abandoned or revised based on ever changing circumstances or contexts.
Originality/value
The study bridges the gap between theory and practice of environmental CSR by enriching the understanding of academics and practitioners on CSR and environmental sustainability relationships in Lagos Megacity.

Abstract
Purpose
In less than a decade to sustainable development goals (SDGs) there is a threat of household waste emanating from sub-urban sprawl especially in developing countries. Private approaches with government-enabling environments have been proved a successful platform for urban services such as housing provision and telecommunication in developing cities. Still private solid waste management (PSWM) seems different in Nigeria. Therefore, this paper aims to investigate the possible perceived hindrances facing PSWM organisations and proffer feasible policies to enhance sustainable clean and healthy cities.
Design/methodology/approach
Seven communities within Benin City sub-urban environs were adopted as the study area to accomplish the research’s objectives via a phenomenology type of qualitative research design. The study analysed the collated data from the knowledgeable participants via a thematic approach.
Findings
Lax legislative, absence of institutional framework, inadequate economic motivation, inadequate technical operations, among others, emerged as the encumbrances faced by PSWM firms. Wastes dumped along unethical locations such as streets, roads, uncompleted buildings, culverts and drainage channels, and undeveloped plots emerged as the encumbrance outcomes. Findings show that proffering feasible policy solutions to tackle identified hindrances can promote the achievement of SDGs across semi-urban locations in Nigeria.
Research limitations/implications
This research is restricted to urban household waste management by PSWM within Nigeria. Also, the study identified the challenges and proffer policy solutions to enhance improved clean environment within the sub-urban and urban cities.
Practical implications
As part of this study’s implications, results from this research intend to guide government policymakers and PSWM firms to encourage collaboration in designing appropriate strategic and educational programmes for the householders (customers) in sub-cities. It will be achieved via feasible policies that are tailored towards achieving sustainable health and environment-friendly sub-urban locations.
Originality/value
This paper intends to enhance proper PSWM and create sustainable cities via collaboration. Also, the paper engaged key stakeholders via a qualitative research design to proffer possible solutions to the menace of sub-urban and urban household waste management.
