This paper explores measurement of product performance with respect to circular economy (CE) principles.Potential indicators are assessed with special attention given to questions such as: the variables that should be measured; how these variables should be assessed; and in which format they should be presented.The resulting considerations are used to develop a prototype whose design is informed through feedback from CE experts.The prototype uses a points-based questionnaire which converges into a simple final result with minimum and maximum Plumbing Parts limits.The selected approach is critically appraised, and its utility for decision-making discussed.
The prototype is tested against a product in the chemical processing industry.The strengths include: ease of use; simplicity; speed; and an effective metaphor for the diffusion of CE principles.The limitations include: the opaque and potentially misleading nature of a single metric; superficial engagement with decision-making; and the reliance on context-specific assumptions.Future developments could include refining the approach to encourage deeper reflection, and generalisation of the approach to Swivel Glider Recliner different industry sectors or sustainability frameworks.
