Polyethylene

POLYETHYLENE & ENVIRONMENTAL DEGRADATION By: Dustin Koontz

The Significance of Polyethylene
Plastic bags are made from polyethylene, the world’s largest commercial polymer.
Requires petroleum and toxic materials to manufacture.
It is a recyclable material, however…
Most bags and wrappers end up in dumps or the ocean.

Uses of Polyethylene
Plastic bags
Any sort of food wrapper
Bottles
That plastic that electronics always come in
Anything that you would describe as “plastic”

Environmental Concerns: On Land
Not biodegradable (takes 1000 years to degrade.)
Most plastic bags & many polythelene products are not recycled.
8 billion pounds of plastic enter land based water sources yearly (a large contributor of which are plastic bags.)
60 million tons of polythene used yearly.
1 million plastic bags used worldwide a minute.

Environmental Concerns: In the Ocean
Plastic bags in the ocean go through the process of plastic photodegradation.
Contribute to the great pacific garbage patch.
Enter the food chain (along with PCBs absorbed during photodegradation) when consumed by wildlife.
Can reach humans through biomagnification.
Can out mass zooplankton (the dominant life in the area) by up to seven times.

Movements against plastic bags
Some independent stores, diners, cafes, and restaurants are using biodegradable bags.
Eco-totes are commonly used, especially in countries like Ireland and other European countries that have banned plastic bags.
Seattle bag tax coalition intends to have the tax reduce environmental impact. Many similar things across the US are starting to pop up, even in places like Arizona.
National geographic expressed environmental concern as early as 5 years ago for this issue.

Proponents of plastic bags
The Washington Food Industry is opposed to the bag tax.
Companies like plastic bags as they are incredibly cheap.
No extra burden on consumer.

Things for consideration
Future taxes on grocers buying plastic bags (taxes have been implemented in countries to curb usage.)
Taxes (Seattle bag fee ordinance) on usage at the consumer level
Environmental impact
Personal cost
