Pivotal Strategy of the Circular Economy: A Five‐Pillar Framework for Sustainable Transformation

The shift from a linear to a circular economy is seen as a pivotal strategy to address unsustainable practices and mitigate environmental degradation. However, progress toward implementing a circular economy is often hindered by greenwashing, limited infrastructure, inconsistent policies, technological advancements, and a lack of consumer education. This paper proposes a five‐pillar interdisciplinary framework—Economics, Infrastructure, Policy, Science/Engineering, and Education—to provide a forward‐looking perspective in guiding the effective adoption and implementation of circular economy principles. By using the recycling of polyethylene terephthalate (PET) bottles in Huntsville, Alabama, as an exemplary case, this research identifies the systemic barriers and opportunities associated with transitioning to circular practices. Key findings highlight economic disincentives, inadequate recycling infrastructure, fragmented policies, and limited public awareness as critical challenges. This paper demonstrates the importance of collaborative policymaking, investment in infrastructure, and education initiatives to address these barriers. By emphasizing the interconnectedness of the five pillars, this research offers actionable insights for achieving sustainable waste management and advancing the circular economy. The findings contribute to a deeper understanding of how interdisciplinary strategies can drive meaningful progress in sustainability efforts.
