Environmentalists, ecologists, and governments have become interested in sustainability challenges from the perspectives of the economy, environment, and society. In this regard, the circular economy offers the chance to reduce production and consumption activities, reduce carbon footprints, and simultaneously convert waste into resources. Models and solutions for the circular economy supported by industry 4.0 technologies were created to create new products with diverse uses from ones that are nearing the final phase of their life cycle. In this chapter case study was done in the uses of Industry 4.0 technologies on a paper manufacturing industry. Using the framework that has been built, the research utilizes the Multi-Grade Fuzzy Approach (MGFA) to evaluate each selected organization’s present level of Industry 4.0 and circularity readiness. A roadmap is also developed for the adaptation of circular strategies for paper manufacturing companies, industrialists and academicians to improve circularity in their supply chain.
