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.

Enormous Amount

An enormous amount of municipal solid waste (MSW) has increasingly become a threat for many cities around the world. As an effective method of waste disposal, source separation program of MSW is concerned by more and more researchers across disciplines with other waste management options for the purpose of abating degradation in urban environment. The purpose of this article is to present the achievements of theoretical and empirical studies in the field of source-separation programs around the world in recent years, which may provide a new insight of environmental problems into decision making of governments and citizens.

Solid Waste Incinerator

Incineration is regarded as one of the common methods for energy recovery as well as waste reduction, due to the high amount of waste generation in major cities; for instance Tehran (7000-8000 ton/day), and lack of sufficient landfill. The proper treatment and recycling of municipal solid waste incinerator (MSWI) residual ashes is one of the challenges which decision makers are faced with. In order to investigate the feasibility of the recycling of ashes, the sustainability index is considered. This evaluation is carried out by means of the multi-criteria decision-making approach for assessing sustainability (MIVES) and the Analytical Hierarchy Process (AHP) as a conventional decision-making tool. Six possible scenarios in Iran was determined, BA/FA landfilled with solid waste system (current scenario), Partial substitute of raw materials for cement/concrete, Ceramics and glass/glass-ceramics production, Geotechnical applications, use of BA/FA as alternative adsorbent and Fertilizers in agricultural soils. The assessment was accomplished through 25 questionnaires distributed among experts which includes environmentalists, governmental decision makers, academics, and technical groups. The questionnaires comprised of 33 pairwise comparison matrices, and the experts were asked to systematically compare elements of the constructed hierarchy in numerical terms. According to the results, reusing MSWI ash as a partial substitute for raw materials in cement/concrete scored highest in ranking among other potential MSWM scenarios (with a relative weight of 0.234). The results also reveal that the utilization of BA/FA as alternative adsorbents and as fertilizers in agricultural soils are not to be currently pursued in Iran (with relative weights of 0.117 and 0.129 respectively).
