The Various Advantages of Producing Algae Biodiesel
Muna wa Wanjiru asked:
Algae is a major renewable fuel which can be used to manufacture Biodiesel. One of the companies in New Zealand successfully developed a system for using sewage waste as a substrate for algae and then it produce bio-diesel. An alga is considered as the highest yield feedstock for biodiesel that can produce more enough oil compared to soybeans when grew in an acre.
Actual Biomass algae produced from field trials, which is conducted during the NREL’s aquatic species program. It is being converted using the actual oil content of the algae species grown in the specific program.
There are various advantages of producing biodiesel from algae, which include rapid growth of the plant. Using Algae Biodiesel gives high per acre yield. Algae biodiesel does not used to contain sulfur, toxic materials and it is highly biodegradable. There are some species, which are ideally suited for algae biodiesel production, because their high oil contents in some species.
Algae used to develop from small, singled celled organisms to cellular organisms, some algae have complex distinguished form. Algae can be easily seen at places like damp, bodies of water. Algae are common in terrestrial as well as aquatic environments. Like any other plants algae require three elements to spring up sunlight, carbon-di-oxide and water. Plant algae and some other bacteria convert sunlight to chemical energy, which process call as photosynthesis. Algae used to contain 2% and 40% of lipids or oils by weight. If algae have greater oil, it may results in lower yield annual food crops such as soybeans. Currently only 0.3% of the land of the US, it is getting utilized to produce enough biodiesel.

Algae Biodiesel the Fuel of the Future
Ron Subs asked:
Most American consumers have been hit hard by soaring gas prices, and many people from individuals to research firms are searching for an alternative fuel source that is renewable, economical, and environmentally friendly.
Biodiesel made from crops such as corn and soybeans is one such alternative that most people are aware of, but another option, algae biodiesel, is one of the newest and most promising fuel sources to date. One thing is for sure, if a solution to the ever increasing gas prices is not found soon millions of people will be unable to afford their daily commute.
Many people have put their hopes in biodiesel made from crops as the solution to oil dependency. However, there are problems with biodiesel made from crops namely the displacement of food and the amount of crops it takes to produce a gallon of oil. Using food crops such as soybeans and corn to produce oil takes away from the amount crops that could have been used for food.
Using food crops to make biodiesel is also not very economical, it takes an acre of soybeans to produce about 50 gallons of biodiesel and an acre of corn to produce only about 20 gallons of biodiesel. Compared to the 5,000 or more gallons of biodieseal produced from one acre of algae, food crops are underperforming.
