Ethanol that is made of corn emits a lot of pollutants during production and consumption, but cellulosic ethanol reduces the pollutant admission to the atmosphere making it better than the ethanol made of corn. Corn ethanol and cellulosic ethanol are both made at biorefineries, but they must add heat to the corn in order to produce the corn ethanol. When they make cellulosic ethanol there is no heat added and the cellulosic ethanol actually produces electricity.
When corn ethanol is being produced two harmful emissions are being emitted. One of the emissions is fine particulate matter, which has caused the aggravation of lung disease that can lead to death if aggravated enough. Fine particulate matter has also caused heart attacks in people with heart problems also leading to death. The second emission corn ethanol emits is greenhouse gases. Corn ethanol releases big amounts of greenhouse gases such as carbon
