Abstract
Product-Service Systems (PSS) show the potential to implement the principles of a circular economy based on their characteristics, such as the use of an extended value network or the access of the PSS provider after distribution. PSS research shows that PSS are not inherently circular but must be designed specifically towards circularity. This requires an assessment method that can quantify the dimensions of circularity.
In this paper, an assessment method based on system dynamics (SD) modeling is presented that allows the use of raw materials and the generation of waste to be evaluated in the context of PSS. The SD model is based on a conceptual integration of circular economy strategies into the lifecycle of PSS. The model formulation is described in detail and validated with several tests. The capabilities of the assessment approach are presented in an application scenario. The results show that SD modeling can be used for circularity assessment and can possibly serve as a starting point to enhance circularity.
期刊介绍：
Sustainable production and consumption refers to the production and utilization of goods and services in a way that benefits society, is economically viable, and has minimal environmental impact throughout its entire lifespan. Our journal is dedicated to publishing top-notch interdisciplinary research and practical studies in this emerging field. We take a distinctive approach by examining the interplay between technology, consumption patterns, and policy to identify sustainable solutions for both production and consumption systems.
