CO2, which is a gas produced as a result of combustion, has an important share in greenhouse gases such as SOx, CO, and NOx and causes global warming. As biodiesel produced from algae converts CO2 within the biological carbon cycle, it accelerates the carbon cycle, as a result of which the greenhouse gas effect decreases. C16-C18 methyl esters in biodiesel whose degradability feature resembles dextrose (sugar) do not show any negative microbiological affect up to 10000 mg/L, they decompose rapidly in nature. 40% of diesel in water and 95% of biodiesel in 28 days can be degraded. In the production of biodiesel, catalysts that break the triglyceride bonds allow the esters to become free.
