サーキュラー・エコノミー実現に向けたSmart-circular PSS

文献調査を通じた概念構造の明確化

In response to resource depletion, wastes and emissions, transformational shift from a current linear economy model (production, consumption, disposal) to Circular economy (CE) is attracted attention from academia and major global industries. CE focuses on resource reuse, maintenance, upgrades, and recycling, aiming to minimize resource use and waste while fostering economic benefit of companies. Moreover, the emergence of Industry 4.0 and new developed digital technologies has gained expectation in their role as drivers for implementing CE. Indeed, manufacturing companies have started to adopt digital technologies to their business model to implement CE principles. Given the potential synergy between digitalization and CE, the concept of Smart-circular product-service systems (SCPSS) have been proposed as a new business concept framework, integrating digital technologies into PSSs to enhance circularity and economic viability. However, SCPSS is a nascent concept, lacking precise definition and principles, causing obstacles in its practical implementation for achieving CE goals. This paper thus aims to propose the SCPSS concept by briefly reviewing pertinent literature from related fields. The study addresses the relationships between SCPSS and related business models, the principles SCPSS models should adhere to, and the essential components required for SCPSS planning. Through this investigation, the paper contributes to some knowledge for understanding SCPSS and its potential in advancing CE through digital technology integration.
