Review on Indian Municipal Solid Waste Management practices for reduction of environmental impacts to achieve sustainable development goals

Open dumping is a common practice for MSW disposal in most of the Indian cities, apart from the metro-cities. This practice poses significant environmental and health risks due to toxic and greenhouse gases (GHGs) emission through direct combustion and/or decay of wastes. Therefore, integrated solid waste management (ISWM) using different methods viz., incineration, composting, anaerobic digestions, refuse derived fuel, material recovery facility and sanitary landfilling, is much needed. Accordingly, three waste management case scenarios were studied for year 2001-2051 by keeping weightage of sustainable development goals 2030 of India. Case I depicts Indian present scenario of waste management where 164-735 tonnes/year of wastes would be generated for year 2001-2051. Further, 60% of waste can be treated in case II that help in reducing the land requirement up to 40% from estimated conditions of 2031 i.e., 83.8 × 10⁷ m³. The case III is most ideal waste management condition for year 2031 to reduce 80% waste hence landfill requirement would minimize up to 16.76 × 10⁷ m³ where population is at controlled conditions. This article concludes the formal handling and treatment of ISWM would minimize the landfilling, where LCA can be an antidote to achieve sustainable development goals.

Disaster waste management after the 2016 Kumamoto Earthquake: A mini-review of earthquake waste management and the Kumamoto experience

Millions of tons of debris can be generated by natural disasters, impacting the surrounding environment and posing health risks to the public. Proper handling and treatment of such waste is essential to overcome potential hazards as well as to reduce the burden on natural resources during the reconstruction phase. Disaster waste management can have social, economic, and environmental benefits if planned effectively. This mini-review focuses on the destruction caused and debris generated by the 2016 Kumamoto Earthquake in Japan. In addition, it elaborates upon the treatment of debris in Kumamoto at temporary and secondary storage sites by segregation and the adoption of a full-scale recycling system. It also shows that cooperative networks involving numerous organizations are important in managing a large amount of disaster waste. Finally, it presents comparative discussions of different aspects of disaster waste management in the Kumamoto Earthquake event and other disasters. The experience gained from the Kumamoto Earthquake is important for future disaster waste management planning.

Support for designing waste sorting systems: A mini review

This article presents a mini review of research aimed at understanding material recovery from municipal solid waste. It focuses on two areas, waste sorting behaviour and collection systems, so that research on the link between these areas could be identified and evaluated. The main results presented and the methods used in the articles are categorised and appraised. The mini review reveals that most of the work that offered design guidelines for waste management systems was based on optimising technical aspects only. In contrast, most of the work that focused on user involvement did not consider developing the technical aspects of the system, but was limited to studies of user behaviour. The only clear consensus among the articles that link user involvement with the technical system is that convenient waste collection infrastructure is crucial for supporting source separation. This mini review reveals that even though the connection between sorting behaviour and technical infrastructure has been explored and described in some articles, there is still a gap when using this knowledge to design waste sorting systems. Future research in this field would benefit from being multidisciplinary and from using complementary methods, so that holistic solutions for material recirculation can be identified. It would be beneficial to actively involve users when developing sorting infrastructures, to be sure to provide a waste management system that will be properly used by them.

Source separation of municipal solid waste: The effects of different separation methods and citizens' inclination-case study of Changsha, China

A case study on the source separation of municipal solid waste (MSW) was performed in Changsha, the capital city of Hunan Province, China. The objective of this study is to analyze the effects of different separation methods and compare their effects with citizens' attitudes and inclination. An effect evaluation method based on accuracy rate and miscellany rate was proposed to study the performance of different separation methods. A large-scale questionnaire survey was conducted to determine citizens' attitudes and inclination toward source separation. Survey result shows that the vast majority of respondents hold consciously positive attitudes toward participation in source separation. Moreover, the respondents ignore the operability of separation methods and would rather choose the complex separation method involving four or more subclassed categories. For the effects of separation methods, the site experiment result demonstrates that the relatively simple separation method involving two categories (food waste and other waste) achieves the best effect with the highest accuracy rate (83.1%) and the lowest miscellany rate (16.9%) among the proposed experimental alternatives. The outcome reflects the inconsistency between people's environmental awareness and behavior. Such inconsistency and conflict may be attributed to the lack of environmental knowledge. Environmental education is assumed to be a fundamental solution to improve the effect of source separation of MSW in Changsha. Important management tips on source separation, including the reformation of the current pay-as-you-throw (PAYT) system, are presented in this work.

IMPLICATIONS

A case study on the source separation of municipal solid waste was performed in Changsha. An effect evaluation method based on accuracy rate and miscellany rate was proposed to study the performance of different separation methods. The site experiment result demonstrates that the two-category (food waste and other waste) method achieves the best effect. The inconsistency between people's inclination and the effect of source separation exists. The proposed method can be expanded to other cities to determine the most effective separation method during planning stages or to evaluate the performance of running source separation systems.

Exploring social dimensions of municipal solid waste management around the globe - A systematic literature review

Currently, municipal solid waste (MSW) is experiencing a massive increase in both the amount and composition throughout the world. Effective and efficient MSW management has been widely accepted as an emergent factor for future social development, which requires not only technical innovation, but also the involvement of all stakeholders as well as social, economic, and psychological components. On account of this reality, there is an urgent need for research related to the social dimensions of MSW management. In this paper, a systematic literature review was carried out to characterize and critically evaluate the published literature on the social dimensions of MSW management from 1980 to 2014 in terms of vulnerability, public participation, public attitude and behavior, and policy. A keyword search was first performed by using the Institute for Scientific Information (ISI) Web of Science, which retrieves 1843 documents. After removing the papers that were not closely related to the topic, 200 articles were retained for an in-depth review. In each category, major research issues and observations were summarized, and important insights were obtained. Besides compiling a related list of key references, the analysis results indicate that the global distribution of social dimensions reports on MSW management is inequitable and the research on the social dimensions of MSW management is insufficient, which may attract increased research interest and attention.
