An Integrated Collaboration Framework for Logistics and Supply Chain Management Toward a Circular Economy in Agricultural Businesses of Loei Province

Abstract

Background and Aims: Integrated logistics and supply chain collaboration has become a key strategy for advancing circular economy practices and improving the competitiveness and sustainability of agricultural businesses. This study aimed to: (1) examine integrated logistics and supply chain management processes under circular economy principles among agricultural enterprises in Loei Province; (2) develop value-creation approaches through integrated logistics and supply chain management; and (3) establish collaborative business networks that support value-added agricultural supply chains.

Methodology: A concurrent mixed-methods design integrating quantitative, qualitative, and action research was employed. Quantitative data were collected from 400 upstream, midstream, and downstream entrepreneurs representing five major agricultural commodities using a validated questionnaire (IOC and reliability were established before data collection). Qualitative data were obtained through in-depth interviews with 30 key informants, while action research involved focus group discussions with 50 stakeholders. Findings from the three components were integrated through triangulation to strengthen interpretation and practical recommendations. Quantitative data were analyzed using descriptive statistics.

Results: Integrated logistics and supply chain management was implemented at a generally good level, although upstream producers required greater capacity development. Circular economy practices were applied at a moderate level, with reuse representing the most widely adopted practice. The study developed practical business models and operational manuals that promoted resource efficiency, waste utilization, cost reduction, and value creation across five agricultural commodities. Furthermore, five collaborative agricultural business networks involving 100 members and 15 model entrepreneurs were successfully established, strengthening inter-organizational collaboration throughout the supply chain.

Conclusion: The study demonstrates that integrating logistics and supply chain collaboration with circular economy principles provides an effective framework for enhancing resource efficiency, reducing logistics costs, creating business value, and strengthening collaborative agricultural networks. The proposed framework offers practical guidance for promoting sustainable agricultural development and supports circular economy policy implementation in regional agricultural systems.
