This thesis deals with a multi-objective approach to promote the circular economy in the context of chemical recycling of plastic waste. The main objective of this thesis was to develop a multi-objective decision making tool that could be integrated into the iSMA framework developed by Pacheco-Lopez et al. (2023) to fill an identified gap. The literature review highlighted the growing importance of sustainable plastic waste management, describing current waste management methods and their limitations, as well as the potential of chemical recycling to improve this situation. Chemical recycling, in particular pyrolysis, offers a promising way to convert plastic waste into valuable resources, although challenges remain in terms of efficiency and environmental impact. The iSMA framework generates Pareto optimal solutions for different recycling paths, but a tool was needed to objectively select the best options. This tool, developed in Python, implements the multi-objective optimization methods TOPSIS and PROMETHEE, and includes a sensitivity analysis module to assess the stability and robustness of alternatives in the face of uncertainty in the weighting of criteria. The results obtained show that the tool is functional and able to provide relevant rankings, although depending on the quality and completeness of the initial data. Future prospects include extending the tool to other areas of environmental sustainability, integrating new optimization methods, and specifying criteria weightings guided by local sustainability policies.

The utilization of bio-resourced macromolecules for polymer applications has been the subject of increasing interest, mainly for sustainability and functionality reasons. This Special Issue of Processes brings together nine papers from leading scientists and researchers active in the area of “Sustainable and Renewable Polymers, Processing, and Chemical Modifications”. The collected papers include seven original research and two review articles related to renewable feedstock for polymer applications, processes for the fabrication of renewable polymer-based nanomaterials, the design and modification of renewable polymers, and applications of renewable polymers. The journal Processes will continue to nurture progress in this field through its position as an open access platform.

The protection of human health and the environment (representing the main reason for waste management), as well as the sustainable use of natural resources, requires chemical, biological, physical and thermal treatment of wastes. This refers to the conditioning (e.g., drying, washing, comminution, rotting, stabilization, neutralization, agglomeration, homogenization), conversion (e.g., incineration, pyrolysis, gasification, dissolution, evaporation), and separation (classification, direct and indirect (i.e., sensor-based) sorting) of all types of wastes to follow the principles of the waste hierarchy (i.e., prevention (not addressed by this issue), preparation for re-use, recycling, other recovery, and disposal). Longstanding challenges include the increase of yield and purity of recyclable fractions and the sustainable removal or destruction of contaminants from the circular economy.This Special Issue on “Advanced Technology of Waste Treatment” of Processes collects high-quality research studies addressing challenges on the broad area of chemical, biological, physical and thermal treatment of wastes.
