Since algae are easy to grow it is can also be cultivated in large scales such as having the production large open ponds. In this way the process can use carbon dioxide from power plants that are coal-fired and have a greater control over nearby emission.1 The fatty acids that are extracted from the algae is not not all that can be used for a specific purpose, the carbohydrates can be used to make ethanol and from some parts of or the entire algae bio gas can be made.2
Algae can be grown in large ponds, as mentioned earlier but also in places such as pools, tanks and bioreactors. This quality can provide purpose to location that today are not suitable for production of food, such as deserts, waste land and even wastewater. The efficiency of the fatty acid production is profitable and usually around 20-50% but depending on which specie the oil content can be up to 80 %. Today the lipid production from from algae is done in open tanks and bioreactors, commonly in China, USA, Indonesia, Taiwan, Japan and Israel.1 These methods can be applied in other countries as well, an interesting idea is the opportunities in developing countries and also usage of large desert areas that are available but not used for any specific purpose.
