Lean Green Methodologies and Circular Economy: A Case Study

Implementing Lean Green methodologies in the circular economy optimises companies’ and industries’ environmental and economic performance. This study investigates how Lean Green can support or hinder the implementation and sustainability of the Circular Economy in organisations. The study aims to explore the concepts of Lean Green and Circular Economy and their relationship and integration for mutual benefit. Subsequently, a case study is carried out to develop a roadmap of Lean Green and Circular Economy tools, presenting a methodology for developing a roadmap to improve an Industrial Wastewater Treatment Plant. Throughout the process, various environmental problems and impacts associated with the treatment plant operation were identified, ranging from energy consumption to the use of chemicals and waste management. To address these challenges, concrete actions based on Circular Economy and Lean Green principles were proposed, promoting the reduction of volatile organic compound emissions, the incorporation of waste into production processes, among others.
