The Possible Risks Of Ethanol Transport

By Leslie Ball


The production of ethanol has increased over the years. During the year two thousand, over two billion gallons are being produced, while in two thousand eight, it reached to over nine billion gallons. By two thousand twenty two, this is expected to triple in amount. That is really huge.

There had been studies that show how biofuel production can impact the environment negatively. Ethanol transport needs to undergo specific processes and strict policies in order to avoid possible accidents related to contamination. Leakage, spills, and explosions that will result to huge fires must be avoided. Because of this, the transport can only be possible through barges, car tanks, and tanker trucks. However, this may still not be completely safe.

Depending on the cycles of the supply chain, the biofuel can be produced as one hundred percent ethanol or combined with certain amounts of gasoline. When transported, these are denatured. Little do communities like Denmark, TN know about the health and environmental risks of the transport process.

No matter how sealed a container or trailer is that contains the biofluel, the seal can still be degraded because of the tendency of the mixed compounds to attract water from the atmosphere. The combined gases can burn the skin and the victim may not be warned of its presence because it can hardly be seen by the naked eye. The two different fuels have a lot of differences in their characteristics concerning conductivity, density, boiling point, and solubility.

Corn is the raw material which will be processed into a biofuel. Studies show that improper growth of corn can affect the purity of the end product. If combined with gasoline without proper procedure and safety measures, they can leak from containers causing environmental contamination.

This can greatly contribute to air and water pollution. The moment it leaks, it emits gaseous particles in the atmosphere and in water. Once the humans, plants, and animals breathe in the air or take in the water, they will definitely get sick. Dispensing, storing, and blending the fuels must be done by professionals and away from public places because they can explode if exposed to very hot areas.

Rail transport of these biofuels is a public safety concern. Some of these are travelling to populous areas. If something goes wrong with the storage, they could release large quantities of poisonous fumes, which is dangerous to the health. Many are not even aware that there are already some particles of this chemical mixed with the air because it is nearly invisible.

Government agencies have taken measures to protect the citizens and the environment from potential harm. They have issued detection technologies to see if there are leaks that could lead to contamination. However, these are limited to other kinds of commercial gases and fuels. There is still no other technologies that can support the chemical characteristics of blended ethanol and gasoline.

Comparably, the damage of this kind of fuel, especially when blended with gasoline, is even more dangerous than that of petroleum. This is because it can reach a relatively higher toxicity since the chemical components are mixed with that of gasoline. Thus, it can cause more pollution. In addition, the chemicals are carcinogenic and can linger for a long time in water and air.
