Not only making products that are useful to human is crucial, but also making them eco-friendly, which are not harmful to environment. By looking up some of the news articles and websites that are related to chemical engineering, chemical engineer's actions towards saving the environment were shown from several sources.
Among those according to the Chemical Engineers in Action website, http://chemicalengineering.org/enviro/index.html, it shows what they do to make the environment better. As what other chemical engineers do, they develop technologies, monitor devices, and model engineering techniques. However, what they do differently is first, minimize the toxicity of pollutants produced that might affect the environment, such as, air and soil. Second, devise how to enable the waste to be reused. Also, they contribute to water management to purify the water that are edible for human.
One of the achievements they made is saving the earth in terms of a transportation. It is within bounds to say that transportation, vehicles, trucks, trains, airplanes, and buses are essential in nowadays life. Nevertheless, it is recommended to be less used since the exhaust from those transportation's engines cause the air pollution.
They devised two major ideas that helps reduce the pollution.
- Catalytic Converters
Catalytic converters are known as one of most important contributions of controlling air-pollution. Chemical engineer John Mooney and the chemist Carl Keith used this converters to allow it to maximize the catalyst-coated surface area. It helps the exhaust produced to be less likely to be exposed and to harm the air. The converters also does not require a lot amount of metal to operate which makes it cost effective.
- Cleaner-burning fuels
Cleaner-burning fuels, which is based on advanced petroleum refining techniques, also help reduce the air-pollution. These engineering techniques allowed it reduce the pollutants. These made it possible to devise improved engines with more efficient air management systems and these systems destroy and reduce pollutants.
