How can Polyethylene make an impact on society ?
Bags can litter into streets making clean up difficult. High civic costs to governments, mostly because of the cleanup efforts High costs to the government, which results in loss of other funds offered to them.
Chemical Formula & Generic Name
-Generic Name: Ethene homopolymer -Chemical Formula: -[-CH2-CH2-]-n ( “Polyethylene”, 2006)
The raw materials that consists to make polyethylene is ethylene which consists of carbon and hydrogen. (Castellion. M ,2010)
Careers with Polyethylene
A career that associates with polyethylene is the discoverer of polyethylene. It was discovered by a German chemist named Hans von Pechmann. He was heating diazomethane (H2C=N=N) when he observed the formation of a white, waxy solid. When his colleagues identified the substance as containing repeated methylene (-CH2) units, they first called the material polymethylene. Von Pechmann did not...
Negative Effects on the Compounds.
- When it is above the melting point (Varies: about 85°C −110°C) it has to thrown away. Cannot be re-used again. (Polyethylene,2006)
Benefits of the compound.
- A variety of objects can be produced by polyethylene. (Example: toys, swimming pool covers, pipes, hula-hoops, dinnerware .etc.) - There are no health hazards from polyethylene (Polyethylene, 2006)
Polyethylene comes in two different ways one in high density polyethylene and the second one is low density. High density Polyethylene is used primarily in blow-molded bottles for household cleaning products, motor oil, and food items such as maple or chocolate syrup, orange juice, and milk. (Castellion, M, 2010). Low density Polyethylene is used in packaging film; shopping, trash, and...
How can Polyethylene make an impact on the...
Manufacturing polyethylene bags releases harmful gases in the environment. Polyethylene bags block drainage pipes & cause widespread flooding. Land & sea animals mistakenly digest these bags, causing illness & death. Non-mobile marine species colonize on the polyethylene plastic and are transported to different places where they can destroy the new eco-system. Wind can carry the bags...
How can Polyethylene make an impact on humans?
Suspected human carcinogen (cancer-causing agent). When in direct contact with food, chemicals can leach and contaminate it. (“Plastic”, 2011)
