Research on multi-objective recycling network for used electromechanical products

Area of Science:

• Environmental Science
• Operations Research
• Industrial Ecology

Background:

• Used electromechanical products contain hazardous materials, posing environmental and health risks.
• Effective recycling networks are essential for managing e-waste and conserving resources.
• Current recycling strategies require enhancement to improve efficiency and sustainability.

Purpose of the Study:

• To propose a multi-institutional recycling network for used electromechanical products.
• To develop a multi-objective mathematical optimization model balancing economic, environmental, and social objectives.
• To provide a framework for government entities and recyclers to improve e-waste management.

Main Methods:

• Development of a multi-objective mathematical optimization model for the recycling network.
• Application of the multi-objective Gray Wolf optimization algorithm for analysis.
• Sensitivity analysis of key parameters (economic costs, carbon emissions, employment).

Main Results:

• The proposed model effectively analyzes the recycling network for used electromechanical products.
• Sensitivity analysis confirmed the interrelationships between economic costs, carbon emissions, and employment.
• The model demonstrates validity and practicality in addressing e-waste challenges.

Conclusions:

• The study promotes a circular economy by reducing resource depletion and pollution.
• The established network can stimulate industrial growth and create employment opportunities in the recycling sector.
• Findings support national strategies for waste management and the development of comprehensive recycling systems.
