Abstract
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.
