PurposeSmart cities in India are going to be a reality very soon by turning challenges into opportunities for the society. However, due to rapid increase in population burden, fast urbanization and growing demand of advanced services in the smart cities, the quantity of per capita municipal solid waste (MSW) has escalated. Moreover, the COVID-19 pandemic has further challenged the municipal solid waste management (MSWM) system with the increasing amount of infectious wastes coming from households (HHs), quarantine centers, healthcare facilities, vaccination centers, etc. Therefore, the present study attempts to explore and analyze the various dimensions of sustainable MSWM system in the smart cities.Design/methodology/approachThe study identifies 13 factors of sustainable MSWM system from the literature, field surveys and stakeholders' opinions. Thereafter, stakeholders' opinions are collected and analyzed using total interpretive structural modeling (TISM) approach to explore the interrelationships among the factors of sustainable MSWM system. These relationships are further validated through the empirical investigation of the real-life case study of Rourkela Municipal Corporation (RMC), Odisha, India.FindingsThe TISM approach places all 13 factors into six levels in the hierarchical digraph depending upon the inputs received from the various stakeholders on their interrelationships. Study also validates the proposed TISM model by collecting the data of RMC, Odisha, on the development of MSWM system over the period of 2015–2021.Practical implicationsThe study also highlights various implications for the other developing cities and stakeholders to set up the roadmap for developing the sustainable MSWM system. Study defines “IT platform” and “awareness among citizens” as the base of the sustainable MSWM system in any smart city.Originality/valueThe present study is the first of its kind to explore the interrelationships among the factors of sustainable MSWM system by using TISM approach. Moreover, the proposed TISM framework is further validated through the empirical journey of one of the smart cities in India.

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.

With the implementation of new policies supporting renewable natural gas production from organic wastes, Canada began replacing traditional disposal methods with highly integrated biogas production strategies. Herein, data from published papers, Canadian Biogas Association, Canada’s national statistical agency, and energy companies’ websites were gathered to gain insight into the current status of anaerobic digestion plants in recovering energy and resource from organic wastes. The availability of materials prepared for recycling by companies and local waste management organizations and existing infrastructures for municipal solid waste management were examined. Governmental incentives and discouragements in Canada and world anaerobic digestion leaders regarding organic fraction municipal solid waste management were comprehensively reviewed to identify the opportunities for developing large-scale anaerobic digestion in Canada. A range of anaerobic digestion facilities, including water resource recovery facilities, standalone digesters, and on-farm digesters throughout Ontario, were compared in terms of digestion type, digester volume, feedstock (s), and electricity capacity to better understand the current role of biogas plants in this province. Finally, technology perspectives, solutions, and roadmaps were discussed to shape the future in terms of organic fraction municipal solid waste management. The findings suggested that the biogas industry growth in Canada relies on provincial energy and waste management policies, advanced technologies for diverting organic waste from landfills, improving biogas yield using existing pretreatment methods, and educating farmers regarding digester operations.
