INTEGRATION OF CIRCULAR ECONOMY PRINCIPLES IN HIGH-MIX PRODUCTION PLANNING - FROM MONITORING TO OPTIMIZATION

Szymon Ziaja, Pawel Bogacz

Abstract

This paper addresses the problem of integrating circular economy (CE) principles into production planning processes in high-mix manufacturing environments. Although environmental indicators are increasingly monitored in industrial practice, their role in operational planning decisions remains limited. In many cases, data collection is not followed by its effective use in decision-making processes. The aim of the paper is to present an author-developed conceptual approach that enables the transition from monitoring to optimization, in which environmental parameters – such as material waste, energy consumption, and carbon footprint – become active criteria in production planning. The proposed approach extends the author’s previous concept of sustainable production planning maturity assessment, focusing on the environmental dimension and its operationalization within planning decisions. The paper identifies key planning decisions where circular economy principles can be implemented, including batch sizing, job sequencing, resource allocation, and planning of repair and recovery processes. Particular attention is given to the mechanism of transition towards higher maturity levels (P4–P5), where environmental data are integrated into multi-criteria decision-making. The proposed concept contributes to the operationalization of circular economy principles in production planning and may serve as a foundation for further research on sustainable planning systems in high-mix environments.
