Data as an enabler of circular transitions in the coated abrasives industry

Abstract The Circular Economy (CE) is a key factor in achieving global and local sustainability. In Europe, the goal of becoming a carbon-neutral continent by 2050 has accelerated the transition to sustainable practices across many sectors, including manufacturing. The industrial sector can play a large role in the CE by reducing waste and increasing recycling. Coated abrasives are multi-material; short-lived products used worldwide in various grinding and surface-conditioning applications. Since waste reduction is preferable, an alternative handling approach for end-of-life (EOL) coated abrasives can be proposed with an advantage. Although the technical aspects of recycling have been studied to some extent, the prerequisites for the large-scale return of EOL coated abrasives have not been explored. This paper presents an industrial case study in the coated abrasive sector, aiming to advance material flow models, and recycling concepts. Crucial factors impacting the circular economy in the study, such as legislation, waste management, strategy and data governance, are discussed. The study addresses the significance of the recycling concept, outlines the prerequisites for its successful implementation, and proposes various models for the future recovery of EOL coated abrasives. The recycling of abrasive grains may help reduce the demand for virgin raw materials. This research is important as it supports the European Union’s objectives for advancing the circular economy.
