Abstract
Waste heat recovery (WHR) is a crucial aspect of energy conservation and sustainability efforts across various sectors. This comprehensive review explores the significance of waste heat, its sources, recovery techniques, applications, challenges, and future prospects. Waste heat arises from industrial processes, power generation, transportation, and residential sectors, representing a significant untapped energy resource. Various techniques such as heat exchangers, organic Rankine cycle (ORC) systems, thermoelectric generators (TEGs), and combined heat and power (CHP) systems offer opportunities for capturing and utilizing waste heat effectively. Applications of WHR span industries, power plants, transportation, and residentialcommercial buildings, with the potential to enhance energy efficiency and reduce environmental impact. However, WHR faces technical, economic, and regulatory challenges that require concerted efforts to overcome. This review examines case studies of successful WHR implementations, identifies emerging technologies and research areas, and discusses the role of policy support in promoting WHR adoption. Overall, this paper provides insights into the current state, challenges, and future directions of waste heat recovery, emphasizing its importance in achieving sustainable energy systems.
