The advances in Additive Manufacturing (AM) help the recycling, redesign, and reuse of waste plastics, enabling circular economy supply chains and business ecosystems. This study intended to investigate the barriers to implementing AM in plastic waste management in a developing economy. It shows the hierarchical relationship between those barriers. The findings from the case study reveal that the lack of flexibility to implement circular economy (CE) goals is one of the main barriers to implementing AM in plastic waste management.

Delivery Time Prediction (DTP) is a crucial factor in last-mile logistics. This study proposes a novel method of DTP based on the origin, and destination geographical points (OD DTP) which is fitting for short distances. The findings of this study show that, the trip distance and the trip direction are the most important features when predicting short-distance delivery time.
