“…According to [92,93], cereals are the main crop worldwide, which produces a large amount of waste, such as straw, stem, and leaves that contain lignocellulose compounds [94], which are mainly used for bioenergy generation. Some methodologies to obtain bioactive compounds from crop waste have been described [95][96][97][98], focusing on extracting those with high antioxidant capacity, given the great demand of the food, pharmaceutical, and cosmetic industries for natural products with this characteristic. Other techniques focus on obtaining aromatic [99] and phenolic [100] compounds from the coffee husk; obtaining polyphenols, carotenoids, nitrogenous compounds, and citric acid from orange peel [101,102]; and obtaining alternariol and tenuazonic acid, compounds with antibacterial activity, from sugarcane bagasse, corn, and wheat bran [103].…”

The reuse and reincorporation of waste are the principles of circular economies. Compost, biofuels, animal feed, dyes, and bioactive compounds can be obtained from the revaluation of organic waste. Research on this subject is scarce and limited to specific sectors, such as agriculture and agroindustry, leaving aside others that generate large quantities of organic waste, such as floriculture. The remains of these sectors have a low decomposition rate compared to other organic wastes. They are a source of bioactive compounds (e.g., essential oils, pigments, phenols) that can be reincorporated into the production chain of various industries. This review describes the composition of waste from agroindustry, agriculture, and floriculture, analyzing their potential revalorization as a source of bioactive compounds and an alternative supply source.
