Sustainable development seeks to meet the needs of the world's population, without compromising the world's resources, but, according to estimates and studies in the field, some of the natural resources are either compromised or about to be depleted. It is estimated that the reserves of coal, oil and natural gas are the first to be depleted, which is why the company must find solutions to overcome the current situation. Currently, biofuels are produced from raw materials such as sunflower, corn and rapeseed. Because these plants are used in the food industry and because agricultural areas are limited to about a third of the planet's total surface area, scientists have focused on finding new ways to produce biofuels from seaweed. Seaweed has a number of advantages, such as doubling the mass in 24-48 hours and the fact that they have a maximum content of 50% of the dry cell mass of oil, a content similar to that of rapeseed cultures. Another advantage is the high amounts of carbon dioxide in the atmosphere that they can capture. The selling costs of biofuels differ depending on the degree of technology and production prices. This paper will present a number of advantages, disadvantages and perspectives of the development directions of the biofuel industry.
