“…Moreover, in urban areas like Noenpayom, Watchaklukya, Ban Thapma, and Rayong City, a recycling network is automatically connected as they are a part of the centralised treatment facility network through energy recovery and final disposal for handling enormous wastes daily. This practical management procedure is also found in other provinces, such as Phuket [ 30 ], Nonthaburi [ 31 ], or a central city of South Korea [ 4 ], where the centralised facility has operated as a part of waste management. Promoting recycling activity and the sorting facility could promote more circularity of PPW material.…”

The circularity of plastic packaging waste (PPW) material via recycling is critical to its circular economy towards sustainability and carbon neutrality of society. The multi-stakeholders and complex waste recycling loop of Rayong Province, Thailand, is herein analysed using an actor-network theory to identify key actors, roles, and responsibilities in the recycling scheme. The results depict the relative function of three-actor networks, namely policy, economy, and societal networks, which play different roles in PPW handling from its generation through various separations from municipal solid wastes to recycling. The policy network comprises mainly national authorities and committees responsible for targeting and policymaking for local implementation, while economic networks are formal and informal actors acting for PPW collection with a recycling contribution of 11.3–64.1%. A societal network supports this collaboration for knowledge, technology, or funds. Two waste recycling models are classified as community-based and municipality-based management, which functions differently by coverage areas, capabilities, and process efficiency. The economic reliability of each informal sorting activity is a crucial factor for sustainability, while empowering people in environmental awareness and sorting ability at the household level is also essential, as well as law enforcement that is effective in the long-term circularity of the PPW economy.

“…The proposed approach has been applied to the design of a MSW treatment facility This calls for better waste management for the improvement of the current practice. In terms of waste characteristics, the MSW is categorized as organic waste (61%), plastic (17%), glass (6%), papers (8%), metal (2%), wood (1%), rubber/leather (1%), cloth (1%), and other waste (3%) [35]. For the sake of simplicity, the four largest compositions of MSW are considered in this study.…”

The main objective of this study is to develop a decision-making tool for the design of the optimal municipal solid waste (MSW) facilities based on superstructure optimization. Currently, the disposal of MSW is a major problem due to the lack of awareness of the negative impacts resulting from dumping MSW into the environment. This poses a challenge for the authorities. MSW valorization such as anaerobic digestion (AD), pyrolysis, gasification etc has been increasingly focused on as an approach when handling MSW to enhance both economic and environmental sustainability. However, with an increasing array of processing technologies, the design of MSW facilities involving the integration of these technologies is becoming tedious and unmanageable. To deal with this problem, superstructure optimization is proposed. It is an effective tool for the design of several chemical processes because it is able to consider all potential process alternatives including the optimal solution using mathematical models based on mass and energy balances. Uncertainty is incorporated into the optimization framework to enhance the robustness of the solution. The proposed methodology was applied in the design process of the MSW facility in Ubon Rathathani province, Thailand, with the objective function of maximizing the profit. The optimization problem was developed as Mixed Integer Linear Programming (MILP) and it was solved using an optimization platform, GAMS, with CPLEX as the solver related to obtaining the optimal solution. The results show there to be as positive profit that is economically viable compared to the use of landfill technology.
