Abstract: Pineapple (Ananas comosus), an important tropical cash crop, is not only rich in carbohydrates, vitamins, and dietary fiber in its fruit, but also contains high-value bioactive components such as cellulose, polyphenols, and bromelain in its leaves, peel, and crown. With the extensive cultivation of pineapple in China, pineapple wastes have become one of the major agricultural byproducts. Through biorefinery approaches, these pineapple-based wastes can be converted into various biofuels including biohydrogen, bioethanol, and biodiesel. This diversified utilization pattern of pineapple biomass resources can maximize resource utilization efficiency, enhance economic benefits, while simultaneously reducing environmental pollution and promoting green sustainable development of resources, thereby contributing to the “dual carbon” goals. Employing an anthropomorphic narrative approach, this paper elucidates the main components of pineapple waste and their applications, vividly illustrating how pineapple wastes achieve the “remarkable transformation” in the energy sector through biorefinery technologies.
