Abstract
This paper aims to present the potential of the Internet of Things and Blockchain applications in enhancing the sustainability of reverse logistics processes. Logistics operations play a vital role in supply chain management and are often referred to as the "dynamo" of the process. Reverse logistics is imperative to bridge the gap between forward logistics (the initial movement of goods) and backward logistics (the movement of products in the opposite direction) to close the supply chain loop and achieve a more sustainable operation that is both environmentally and economically efficient. To achieve this objective, the paper undertook a structured literature review using three renowned databases, namely, Science Direct, Scopus, and Web of Science, via a mapping study. The investigation focused on exploring the sustainable aspects of reverse logistics, which can help organizations attain better environmental and economic returns. Additionally, the paper emphasizes how the Internet of Things and Blockchain applications can contribute to more economical and environmentally sustainable management of reverse logistics operations. The results highlight the key strategies, benefits, barriers, research gaps, and future research directions associated with the integration of these technologies in reverse logistics operations.
