The surge in seaweed farming practices is poised to drive the growth of the seaweed cultivation market in the foreseeable future. Seaweed farming, characterized by its cost-effectiveness, ease of handling, and technological advancements, is gaining global recognition as a viable career option. This method not only elevates the standard of living for coastal residents but also promotes the sustainable utilization of marine and coastal resources in daily life. For example, a report by the U. S. Department of Agriculture (USDA) in February 2022 projects a total fish production of approximately 2. 2 million metric tons in 2021, with aquaculture contributing 1. 7 million metric tons. Egypt's ambitious strategy aims to increase fish production to 3 million metric tons by 2025, leading to a surge in demand for fish feed. Hence, the increasing adoption of seaweed farming practices is a significant driver for the seaweed cultivation market.

The increasing demand for biofuels is projected to drive the growth of the seaweed cultivation market in the future. Biofuels are fuels derived from organic materials, including plant or animal matter, and are viewed as a renewable alternative to conventional fossil fuels like gasoline or diesel. This rise in biofuel demand is influenced by several factors, including environmental concerns, government policies that promote cleaner energy, and the need for improved energy security through decreased reliance on fossil fuels. Seaweed is particularly advantageous for biofuel production due to its rapid growth and high biomass yield, making it a more efficient and energy-dense source compared to terrestrial crops. For example, in May 2022, the International Energy Agency, a France-based intergovernmental organization, reported that biofuel demand in the Asia-Pacific region grew by 9% in 2022, with an additional increase of 12% in 2023, reflecting a continued upward trend in consumption. Thus, the rising demand for biofuels is propelling the seaweed cultivation market forward.
