The Circular Turn in Hospitality: Strategies, Drivers, and Impacts of Circular Practices in the Hotel Industry—A Systematic Review

The Circular Economy (CE) offers an alternative to the traditional “take–make–dispose” model and is increasingly important in hospitality due to the sector’s high resource consumption. This systematic review analyzes 159 studies published between 1995 and 2024, sourced from ABI, BSP, and WoS, and consolidates scattered knowledge on CE practices in hotels. It outlines five strategies for transitioning to CE: energy efficiency, renewable energy, water management, waste reduction, and carbon footprint reduction. These are supported by green procurement, local supply chains, eco-certifications, and regenerative branding, all of which help hotels fulfill stakeholder expectations and support local economies. Guest engagement—through nudges, incentives, co-creation, and digital tools for monitoring and feedback—is becoming increasingly important. The review shows that CE adoption is driven by internal factors such as leadership, staff training, culture, and resources, as well as external factors such as regulation, institutional pressure, and consumer demand for authenticity. Effective collaboration among managers, staff, suppliers, policymakers, and certifiers is essential for achieving systemic adoption. CE is moving from operational efficiency to broad innovation benefiting the environment, economy, and society, despite financial, regulatory, and behavioral challenges. Future research should prioritize establishing measurement standards, addressing scalability issues, and evaluating the global effectiveness of implementation.
