The hospitality industry, a cornerstone of the global economy, faces significant challenges in managing food waste sustainably. Conventional waste disposal methods incur substantial costs and environmental damage. As a result, hotels are embracing sustainable technologies like anaerobic digestion, biogas production, thermal processes like pyrolysis, gasification etc Based on secondary sources, this chapter focuses on economic benefits of Waste-to-Energy innovations in hotels such as cost savings from reduced waste disposal fees, potential revenue streams from energy sales, and improved operational efficiency. Additionally, the chapter highlight environmental benefit including reductions in greenhouse gas emissions and the promotion of a circular economy. Ultimately, this chapter offers insights into integrating renewable energy from waste innovations into hotel operations to achieve economic and environmental goals. It strives to aid hotel managers, policymakers, and stakeholders in adopting and maximizing waste-to-energy systems contributing to a more sustainable hospitality sector.
