This reviw paper is based on a bibliographic study of over 70 articles published in the period 2001-2023 and presents the need for the valorization of agro-industrial by-products, a review of the main research directions for the valorization of plant by-products for the purpose of better environmental sustainability, as well as the most used methods of valorization of this nutritionally valuable waste. The recycling of waste in the cascade represents the engine of the circular bioeconomy that supports finding solutions to problems related to the sustainability of the environment, economic, ethical, social. The methods and procedures for valorizing plant waste are diversified depending on the type of waste and aim to develop new sustainable food system on the consumer benefits. Vegetal by-products still contain valuable bioactive compounds such as fibers, vitamins, minerals, which can contribute to obtaining new products with added value and can become good sources of raw materials for the food industry.
