“…Post-consumer material regards the material generated by households or by commercial, industrial or even institutional facilities in their role as end-users of the product. That material can no longer be used for its intended purpose Several articles modeled the economics of recycling from different stakeholders' standpoint, however, there are still a lot of issues to be settled until a consensus to be achieved among them [13]. By examining all the feasible optimal solutions under certain constraints, such as the quality demand and some other criteria such as the environmental impact, a consensus statement or collaborative decision making, among stakeholders could be reached.…”

In the below-given paper, a holistic, multidisciplinary approach of goods consumption, the economics of recycling and recovery is unfolding, concisely structured, until 2013. The analysis was focused, in brief, on some economic models addressed to environmental issues, tax policies, welfare, waste management, and specifically on recycling and reuse economic modelling. Recycle is an established practice in many countries, while reuse is still under development. Reuse in many aspects is a more desirable option, as far as waste management concerns, and EU legislation seems to encourage this practice. Many industries, especially in the technology section, have developed recycle and reuse programs in order to gain an advantage, while some of them have set a target of zero waste in their production process.

“…Concerning data-centric approaches, 5% of the articles used these methods. For example, Caruso et al (1993) used weights defined based on optimisation techniques, whereas El Hanandeh and El-Zein (2010) and Nakatani and Hirao (2011) defined weights using a Monte Carlo simulation. This low frequency of data-centric methods is likely related to the fact that these methods depend on information availability.…”

“…In addition, to use data-centric approaches does not mean to exclude stakeholder involvement. In Nakatani and Hirao (2011), which defines weights by deterministic methods, stakeholders were involved in the decision process by selecting the acceptance limits to each criterion, instead of defining criteria weights.…”

Multi-criteria decision making to support waste management: A critical review of current practices and methods

Solid waste management is a complex domain involving the interaction of several dimensions; thus, its analysis and control impose continuous challenges for decision makers. In this context, multi-criteria decision-making models have become important and convenient supporting tools for solid waste management because they can handle problems involving multiple dimensions and conflicting criteria. However, the selection of the multi-criteria decision-making method is a hard task since there are several multi-criteria decision-making approaches, each one with a large number of variants whose applicability depends on information availability and the aim of the study. Therefore, to support researchers and decision makers, the objectives of this article are to present a literature review of multi-criteria decision-making applications used in solid waste management, offer a critical assessment of the current practices, and provide suggestions for future works. A brief review of fundamental concepts on this topic is first provided, followed by the analysis of 260 articles related to the application of multi-criteria decision making in solid waste management. These studies were investigated in terms of the methodology, including specific steps such as normalisation, weighting, and sensitivity analysis. In addition, information related to waste type, the study objective, and aspects considered was recorded. From the articles analysed it is noted that studies using multi-criteria decision making in solid waste management are predominantly addressed to problems related to municipal solid waste involving facility location or management strategy.

“…A recent U.S. MFA study on PET revealed that in 2016 only about 4.6% of the PET market was recycled in a closed-loop bottle to bottle pathway, while 9.8% of the PET market was recycled in an open-loop pathway (bottles to fiber, sheet, and film applications). MFA can also be coupled with LCA indicators such as greenhouse gas (GHG) emission, energy consumption, and economic indicators associated with different processes. − …”

The environmental and economic impacts of implementing a circular economy in plastic waste supply chains are not well understood. The proposed systems analysis framework assesses environmental, social, and economic impacts of plastic waste supply chains in a circular economy. The first objective of this article is to identify data sets, models, and knowledge gaps associated with waste plastic supply chain processes, mainly in the U.S. Our literature review indicated that the best data sets exist for virgin plastic resin production, mechanical recycling, landfilling, and incineration, with the materials recovery facility being intermediate, and with chemical recycling the lowest. The second objective of this perspective is to develop an illustrative application of the framework by conducting a preliminary systems analysis of PET bottles with closed-loop recycling. The preliminary systems analysis of polyethylene terephthalate (PET) bottles utilized a linear programming optimization method. Our optimization model indicated that both chemical and mechanical recycling processes are needed to achieve a true circular economy of PET bottles with the least greenhouse gas emissions, specifically reductions of 24% when compared with the linear economy. Good quality and standardized life cycle assessment and techno-economic analysis studies are needed to better understand the environmental, economic, and social impacts of advanced sorting and chemical recycling technologies.
