With the in-depth advancement of the “Zero-Waste City” construction and the high-quality development of the health and wellness industry, Dalian’s coastal health and wellness scenic areas are at a critical window for green and low-carbon transformation. These scenic areas feature sensitive ecological environments and strong public service attributes. However, due to concentrated tourist consumption, there are significant fluctuations in waste generation with pronounced seasonal peaks. Coupled with incomplete resource utilization chains, solid waste management has been under considerable pressure. Based on the foundation of Dalian’s zero-waste city construction and the resource endowments of coastal health and wellness, this paper constructs a quantitative evaluation model grounded in the circular economy. Taking Amber Bay Health and Wellness Scenic Area as an example, it analyzes the comprehensive benefits of the “zero-waste” transformation and proposes development pathways, including a “Blue Cycle” recycling system, integration of new consumption formats, carbon footprint accounting, and cross-departmental collaborative governance. This provides theoretical support and decision-making references for the high-quality and sustainable development of coastal health and wellness scenic areas in Dalian.
