Methodology for a Holistic Product Circularity Analysis (HPCA)
Year: 2025
Type: article
Abstract: This contribution introduces a methodology for assessing product circularity across its lifecycle to enhance sustainability within the circular economy. Addressing the current lack of holistic methods for systematic analysis, this bottom-up approach comprises three phases: data inventory, assessment and analysis, and interpretation of the results. Key data, including material specifics, energy usage, working time of humans and machines, transport routes, and processes involved, are compiled into a digital product datasheet. This facilitates the creation of a detailed product analysis in which the product system, with its inputs and outputs, is described in three stages of the product life cycle. Through the analysis and evaluation of products, the methodology identifies potentials to enhance circularity. Demonstrated through a spice grinder use case, a reference and a circular scenario are evaluated to describe the key differences. The methodology presents a significant step forward in understanding and enhancing circularity within product and material cycles.
