Application of Value Stream Mapping tool to improve circular systems

Abstract

Circular Economy is a model that proposes the closure of loops in the production of goods and services to reduce the depletion of natural resources, pollution, and high levels of production. On the other hand, Lean Manufacturing, is a philosophy that focuses on the development of productivity through the elimination of waste and the increase of value. This article explores the integration of lean manufacturing concepts and tools in a circular context. First, a literature review is presented on the common concepts of waste and value, the circular economy model and the indicators developed previously in the literature. Subsequently, the adaptation of the Value Stream Mapping (VSM) is presented, with the integration of a set of indicators proposed related to the concepts of circularity and longevity. Finally, the application of this tool is presented through a case study, which proves that circular systems can be represented and evaluated with the adaptation of Lean tools.
