Communities store a potential power to support overall performance of urban solid waste management through various creative and innovative arrangements. In Indonesia, the Rukun Warga (RW) is the lowest hierarchy of community organizational system which can implement creative and innovative arrangements to support solid waste management activities with less financial requirement. This study observed RW-based activity on fifty RWs with 412 respondents in terms of 3Rs, household waste separation, waste recycling business and waste bank system undertaken by the community for the sake of cleanliness and income-earning. The result shows that the correlation between level of the activity of the RWs communities in undertaking 3Rs, recycling business and waste bank, and the perceived cleanliness by the community members was validated. It is also showed positive results such as improved urban environment and provided strong push-factor influencing the community members to join the movement and the activities towards sustainable solid waste management are not always cost-intensive activities but a socially bounded engagement would also workable.

Waste recovery is an important aspect towards human and environmental health protection. Unfortunately, proper food waste management is among the serious challenges in the field of solid waste management worldwide. Therefore, it is of great importance to conduct studies towards achieving efficient and cost-effective approaches for food waste management. This study investigated the potential of recovering food waste through maggots’ production as animal feed. The influence of fly attractant application on maggot production was also investigated. The study also investigated the potential of maggot production for waste recovery and reduction. Four different types of food waste (starch food leftovers, rotten bananas and peels, rotten pineapple and peels, and rotten oranges) were used in the investigation process. From the results, it was observed that the application of fly attractants had a significant effect on the production of maggots as determined by the weights after harvesting. Average weight of 94 g/kg of maggot was achieved from banana materials with an application of fly attractant during the 8th day of the cultivation; which is equivalent to a 32.4% increase from the same day when the material was cultured without applying fly attractant. Also, from the starch materials, about 77 g/kg of maggot weight was achieved; which is a 54.6% increase from the same day and the same material but without application of fly attractant. Moreover, the relative dry weight reduction in the trials varied from 52.5% to 82.4%.

Solid waste management is a grave concern for Bangladesh as by 2025 waste generation per capita will be 0.75 kg/capita/day and total amount of waste will reach 21.07 million tons per year. This chapter attempts to uncover the facts regarding waste management along with the policies and regulations existing in Bangladesh by reviewing published secondary documents. The chapter also contains emerging issues of agricultural, industrial, hazardous, construction, and electronic generation and 3R practices in Bangladesh. Legal instruments for waste management in Bangladesh are also examined. It has been found that enforcing authorities lack the capacity to implement their strategies regarding 3R practices for waste management. Case studies about community-based approach, waste recycling sector, and medical waste management have been exemplified in this chapter. Finally, the authors apprised the issues and challenges of sustainable solid waste management practices and proposed the way forward for Bangladesh to have sustainable solid waste management.

Successful transitioning to a circular economy city requires a holistic and inclusive approach that involves bringing together diverse actors and disciplines who may not have shared aims and objectives. It is desirable that stakeholders work together to create jointly-held perceptions of value, and yet cooperation in such an environment is likely to prove difficult in practice. The contribution of this paper is to show how collaboration can be engendered, or discord made transparent, in resource decision-making using a hybrid Game Theory approach that combines its inherent strengths with those of scenario analysis and multi-criteria decision analysis. Such a methodology consists of six steps: (1) define stakeholders and objectives; (2) construct future scenarios for Municipal Solid Waste Management; (3) survey stakeholders to rank the evaluation indicators; (4) determine the weights for the scenarios criteria; (5) reveal the preference order of the scenarios; and (6) analyse the preferences to reveal the cooperation and competitive opportunities. To demonstrate the workability of the method, a case study is presented: The Tyseley Energy Park, a major Energy-from-Waste facility that treats over two-thirds of the Municipal Solid Waste of Birmingham in the UK. The first phase of its decision-making involved working with the five most influential actors, resulting in recommendations on how to reach the most preferred and jointly chosen sustainable scenario for the site. The paper suggests a supporting decision-making tool so that cooperation is embedded in circular economy adoption and decisions are made optimally (as a collective) and are acceptable to all the stakeholders, although limited by bounded rationality.

Abstract This study presents solid waste management planning in an urban green area, Bangkok, Thailand based on the material flow analysis (MFA) and life cycle assessment (LCA). Global warming potential (GWP) of four scenarios for handling solid waste generated in Chulalongkorn University Centenary Park, 2018 was assessed concerning the different ratios of waste recycling, composting, incineration, and landfilling. The results show that alternative systems proposed will result in lower GWP than the existing waste management strategy. The MFA results reveal that the final weights of solid waste ending up in a landfill are 98.8, 101.9, 68.2, and 44.8 t yr− 1 for scenarios 1, 2, 3, and 4, respectively. Increased rates of landfill diversion by increased recycling, composting, and incineration decreased the quantity of solid waste disposed to the landfill and improved the environmental profile of the park waste management system. The LCA results found landfilling to be the dominant source of greenhouse gas (GHG) burdens, while waste recycling was found to result in the reduction of GHG. The results highlight that the use of MFA and LCA as a combined tool to evaluate the environmental performance of solid waste management systems provides valuable information for policy and decision-makers.
