Conservation ecology represents one of the most pressing challenges in the twenty-first century. Growing population and consequent land-use changes cost significant economic losses every year. Thus, conserving biodiversity becomes essential not just for maintaining the stability of global systems but also for securing the long-term interests of the economy. Conservation biology is riddled with sociopolitical issues. Biodiversity conservation is a complex and multifaceted process that often requires careful coordination and continued support from various stakeholders. The logistics of conserving biodiversity become more complicated over time. The circular economy, which aims to reduce resource use and waste by re-circulating products and materials, can contribute directly to these actions. This review explores the intersection of the circular economy (CE) and ecological restoration, emphasizing their synergy in promoting sustainable environmental practices and stewardship. The circular economy, focusing on resource efficiency, waste reduction, and regenerative practices, offers a robust framework for addressing ecological degradation and biodiversity loss. By designing products for longevity, repairability, and recyclability, a circular economy reduces resource extraction pressures, conserving habitats and maintaining ecosystem integrity. Regenerative practices such as forestry and habitat restoration enhance soil fertility, sequester carbon, and improve biodiversity, contributing to resilient agricultural ecosystems. Innovation and collaboration among businesses, governments, and communities are central to advancing sustainable technologies and practices, which support restoration efforts and ensure broad-based implementation. Using suitable case studies, we present various ways CE may contribute to conservation efforts.
