Constraints driven reverse logistics model for Plastic Solid Waste (PSW)

The recovery and recycling of Plastic Solid Waste (PSW) is an important aspect of achieving sustainability. The study reviewed technical constraints (Modeling levers) that influence households' participation in waste recovery and recycling programs from both developed and developing economies. A questionnaire based on the identified levers is developed and distributed to test the validity and significance of the levers. The results are adopted in the development of a levers' based reverse logistics (RLs) model for PSW in the Zambian context. The model provides a new and useful engineering approach for the management of PSW in both developed and developing economies influenced by similar levers.
