Paragraph starter

The integration of collaborative robots into waste electrical and electronic equipment (WEEE) recycling processes, as demonstrated by Álvarez et al. (2020), offers a compelling pathway towards enhanced sustainability. Their research indicates that by strategically assigning tasks to robots (e.g., repetitive or hazardous operations) and humans (e.g., complex decision-making), recycling efficiency, particularly in plastic recovery, can be significantly improved. This leads to greater economic viability through increased revenue from higher-quality recovered materials and contributes to environmental goals by maximizing resource utilization.
