<p>Remanufacturing is an important form of green manufacturing that involves the repair or upgrading of discarded products, ensuring their quality and performance meet new product standards while achieving material and energy savings and reducing carbon emissions. However, challenges such as difficulties in recovery, complex management, and low user acceptance limit the realization of its economic value. This paper provides a systematic review of recent advances in intelligent remanufacturing, covering technological developments, digital platform construction, product lifecycle management, enterprise operational strategies, and supply chain collaboration mechanisms. Then, from the perspective of supply chain management, a framework for an intelligent remanufacturing ecosystem is proposed. Furthermore, based on this framework, future research opportunities are identified at three interconnected levels: product-level lifecycle optimization and carbon accounting, enterprise-level operational and strategic decision-making under environmental transparency, and supply chain-level coordination mechanisms that align economic performance with environmental responsibility.</p>
