Digitalization represents a key driver of the transformation of modern economic systems towards the circular economy model, which is based on the rational use of resources and waste reduction. In the context of managing food bio-waste in the hospitality industry, digital tools enable more efficient planning, monitoring, and optimization of processes. The implementation of technologies such as the Internet of Things (IoT), Artificial Intelligence (AI), big data analytics, and digital platforms contributes to precise measurement of waste quantities, identification of causes, and reduction of food surpluses through automated management of procurement and meal preparation. Tools such as Winnow and Leanpath have demonstrated that digitalization can reduce food waste in hospitality facilities by up to 40%, bringing both economic and environmental benefits. In addition to improving sustainability and competitiveness, digitalization fosters greater awareness among employees regarding the responsible use of resources. Therefore, the integration of digital solutions into the circular economy system of hotels and restaurants represents an important step toward reducing the ecological footprint and achieving sustainable development goals.
