The recovery of bioactive compounds from marine biota such as seaweeds and microalgae has recently gained popularity. Many companies are interested in developing functional products from these organisms. However, the extraction efficiency and bioavailability of bioactive compounds identified in algae, like those of land plants, are restricted. As a result, large-scale recovery of bioactive compounds from algae for industrial uses requires innovative technology, such as green approaches in conjunction with classic extraction methods. Several environmentally friendly extraction techniques have been used to extract the most beneficial chemicals from seaweed in a sustainable manner. The most commonly used technique is solid liquid extraction (SLE), while green extraction technologies include ultrasound-assisted extraction (UAE), enzyme-assisted extraction (EAE), pressurized liquid extraction (PLE), field-based technology, and supercritical fluid extraction (SFE). These strategies were applied while taking into account the recovery rate, time, volume, temperature, pH, ratio, solvent type, and method used. The primary concern when choosing an environmentally friendly extraction method is whether bioactive component recovered is at its peak in terms of effectiveness and efficiency. The information offered in this review has the potential to benefit both industries and scholars.
