Efficient waste management is a transcendental challenge in the contemporary world, where waste treatment plants are essential actors in this process. In this paper, the optimization of a treatment plant through the strategic integration of innovative waste separation components is addressed in detail. This approach relies on a rigorous multi-criteria analysis and the application of the TOPSIS methodology to provide a comprehensive assessment. The research focuses on evaluating the effectiveness of these tools to enhance operational efficiency, mitigate adverse environmental impacts, and simultaneously maximize recovery of valuable resources. From exploring new perspectives to implementing practical solutions, this study seeks to contribute to the forefront of waste management, supporting informed and sustainable decision making in the design and operation of treatment plants.
