(RLEC) in its research publications provides a definition of green logistics, also known as eco-logistics, as a process of delving into how logistics impacts the ecosystem. RLEC also compares green logistics and reverse logistics. It indicates that reserve logistics is the process of products and packaging materials moving from consumers to manufacturers. It aims to re-acquire product values or properly dispose of products. Therefore, reverse logistics is an element of green logistics. Wu and Dunn 1995, pp. 20–38) suggested that green logistics is a combination of the greening of forward logistics, i.e. material acquisition, production, packaging, transportation, storage, and final delivery to end-users, and the reverse logistics that includes waste recovery and disposal
