Critical Reasoning Question #57: Plastic Packaging  
Time 0 0 : 0 0 : 0 0

Plastic beverage containers manufactured from Peter's Packaging Company use a degradable bonding agent (ie cornstarch) to bind together smaller bits of plastic in creating one partially degradable plastic container. On the other hand, plastic beverage containers from Kepsi Packaging are manufactured without binding small bits of plastic together and without using any kind of degradable bonding agent. Managers at Peter's Packaging Company boasted that no less plastic refuse per container is produced when its containers are discarded than when comparable non-biodegradable containers from Kepsi are discarded.

Which of the following, if true, most strengthens the argument above?


Many consumers are ecology-minded and prefer to buy a product sold in partially biodegradable plastic beverage containers rather than in nonbiodegradable containers, even if the price is higher.


The partially biodegradable plastic beverage containers are made with more plastic than comparable nonbiodegradable ones in order to compensate for the weakening effect of the bonding agents.


Both partially biodegradable and non-biodegradable plastic beverage containers can be crushed completely flat by refuse compactors.


Technological problems with recycling currently prevent the reuse as food or beverage containers of the plastic from either type of plastic beverage container.


The manufacturing process for partially biodegradable plastic beverage containers results in less plastic waste than the manufacturing process for non-biodegradable plastic beverage containers.
