The goal of this research is to assess the potential of circular economy principles in reducing waste through the identification of sustainable manufacturing practices. By focusing on the symbiotic net, the re-manufacturing layer, and waste prevention through recycling, the following aims are addressed: to identify sustainable waste prevention practices within manufacturing companies and classify sustainable practices related to the pre-manufacturing layer, symbiotic net, re-manufacturing layer, and waste prevention through recycling; to explore and assess the potential of established sustainable practices to foster Circularity by using Wasted controller, Redirector, Re-producer, and Recycling processes; and to analyze the impact of identified sustainable practices on waste reduction. To achieve these aims, exploratory multiple case studies are employed, focusing on both manufacturing companies and non-manufacturing companies perceived as sustainable. Qualitative interviews with key informants from each company are utilized, followed by a qualitative content analysis. By identifying a set of sustainable practices within the manufacturing industry, companies can better understand the potential of established strategies to be applied and integrated into the company’s business model. This understanding can help bridge the gap between the Circular Economy and the Manufacturing industry and clarify the often ambiguous concept of the Circular Economy. The generation of waste is very much correlated to industrial activities and has a significant environmental impact. It is a key target in many countries to focus on the manufacturing sector to achieve more reasonable waste management and to open up markets for recycled goods. An effective and efficient approach to this end is to integrate the principles of sustainable manufacturing based on a circular economic standpoint. Therefore, the objective of this manuscript is to review the existing work carried out in this regard. We have reviewed many previous papers related to implementing different strategies of a circular economy in manufacturing. Our findings show that there is no systematic review available in the literature that explores the implementation of the principles of circular economy in the manufacturing system.
