Development and validation of a tool for the integration of the circular economy in industrial companies: Case study of 30 companies

Abstract

Circular Economy (CE) implementation is considered an instrumental strategy to help reaching the world's resource, energy, and climate mitigation targets, including the Sustainable Development Goals (SDGs) 2030. However, major barriers must be overcome to facilitate CE implementation in industry such as cultural, market, regulatory and technological considerantions (Kirchherr et al., 2018). Improving management systems within industrial companies is crucial when implementing effective CE solutions in compliance with existing industrial standards such as quality and environmental management systems. However, it is not yet common practice yet due to the lack of standardized, suitable, and easy-to-use supporting analytical tools. This paper attempts to fill this gap by presenting Industrial Circular Economy Questionnaire (ICEQ), a self-diagnosis questionnaire built upon the revision of industrial harmonized standards and, academic literature on business-level CE assessment tools. ICEQ, compiling a set of 165 questions for company self-CE assessment, was applied to 30 industrial companies belonging to 17 economic sectors (automotive, machining and metalworking transformation, waste management, machine tool, etc.) in the Basque Autonomous Community (BAC) in Spain. The automotive sector stands out with 70% of circularity while Machining and metalworking transformation only has 34%, showing that the automotive sector is more conscious of CE since they must comply with End-of-Life Vehicles (EoLV) legislation.
