Decisions related to waste management were affected to contain the advance of the new coronavirus pandemic. Different measures have been adopted between countries around the world. This study aims to assess changes in decision-making on solid waste management in Brazil and Portugal during the COVID-19 pandemic, considering the socioeconomic differences and the context of waste management in each country before the health crisis. A literature review was carried out on scientific bases, PubMed, Google Scholar and Web of Science. Differences were noted in decisions and guidelines for good practices in waste management, with measures being observed in a decentralized manner in Brazil, differently from what was observed in Portugal. In this way, the understanding of urban waste management during the COVID-19 pandemic in Brazil becomes complex, in addition to the territorial extension and the diverse social composition, due to the decentralization of decision-making, while Portugal centralizes decisions related to waste management and has a smaller population and territorial extension.

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.

AbstractAs cities in Nepal grow fast in an unplanned manner, low-lying areas face the risk of flooding and waterlogging exacerbated by the impact of climate change events such as excessive rainfall. The problem is aggravated when solid waste is not managed properly. This chapter provides an account of some of the key findings from a large research project where we examined how proper solid waste management would help reduce the risk of flooding and waterlogging using the metropolitan city of Bharatpur as a case study. It also examines the effectiveness of information dissemination and installation of waste bins on the streets as a strategy for making urban communities cleaner. The benefits that cities would derive in terms of increased property value when communities get cleaner are quantified. Household surveys and other data are used to examine households’ willingness to pay for improved municipal solid waste management and how this could be financed in a sustainable manner to increase urban resilience as a strategy for community-based climate change adaptation.

Sustainability Index

Purpose – The purpose of this paper is to assess a comprehensive model that computes a single score in order to evaluate the sustainability of the municipal solid waste management (MSWM) system of a given city. The model was applied to calculate the sustainability index for the MSWM of Istanbul, Turkey as a case study. Design/methodology/approach – Different sustainability indicators (including environmental, economical, and social parameters) along with exergy analysis were integrated to utilize an analytical hierarchy process (AHP) under a life cycle perspective. Findings – The Istanbul case study helped to verify that AHP is an effective and efficient decision-making tool. According to the analysis, the current MSWM system of Istanbul is sustainable, and the sustainability can be improved only by changing the amounts to be treated by the current system without any new technological investments. Research limitations/implications – The Municipal Solid Waste Management Sustainability Index (MSWMSI) in this study allowed to integrate large amount of information on interrelated parameters and the sustainability indicators in the whole life cycle into one value that is useful for a general or a comparative judgment and helpful in MSWM decision making. Originality/value – The fact that the weighting assigned to each component in the model is dependent on the decision makers’ evaluations enables the model to be tailored to any city of concern. The model allows the user to readily determine the relative contribution of each criterion or sub-criterion to the final MSWM selection. It is convenient to use and the computations can be run utilizing available specialized software as well as computing by hand.
