<p>Horticultural waste management encompasses a range of strategies and methods that are employed to efficiently handle and responsibly dispose of waste generated from various horticultural activities. The proper management of horticultural waste has become increasingly crucial due to its potential environmental impact and the need for sustainable resource utilization. This comprehensive approach involves not only waste disposal but also the exploration of innovative techniques for converting horticultural waste into valuable products. The conversion of horticultural waste into value-added products has garnered significant attention in recent years, driven by the desire to minimize waste, conserve resources, and reduce energy consumption. In the first part of this review, an in-depth exploration of the diverse compositions present in horticultural waste is presented. Horticultural waste comprises a wide range of phytochemicals, antioxidants, and essential oils, which possess a range of beneficial properties that can be harnessed for commercial purposes. Researchers have explored the potential of horticultural waste as a source of bioactive substances, which can be extracted and utilized in various food and non-food processing industries. Furthermore, the second part of the review provides a comprehensive overview of the current landscape of transforming and developing value-added products derived from horticultural waste. The objective of this paper is to provide a comprehensive overview of the current state of waste management in horticulture by surveying the research work conducted by numerous researchers in the field. We expect that this survey will serve as a catalyst for future studies into the implementation of new technologies for waste management, fostering further research in the field.</p>
