Throw Away, Recycle or Reuse

Throw Away, Recycle or Reuse

Mia Moore

In exercising our single civic duty as American citizens to shop, we produce an amazing amount of waste.

The fact is, we live on a finite planet which sustains the lives of every human who has ever lived and will ever live, making our waste and its final destination a huge problem.

The answer couldn't possibly be as simple as throwing it into the trash can, setting it out on the curb to be taken to a landfill. It just feels wrong. Most of use have been conditioned to believe recycling is the best answer to our waste problem. Recycling makes rational sense and makes us feel good. But is it the solution to the problem?

The answers vary depending on who you're talking to. The pro-recyclers have already made up their minds and committed fully to recycling. You may have noticed an almost religious-like connection to this solution, complete with projecting judgement of moral superiority. Pro-recyclers often site landfills as the biggest problem because they leak toxins into our soil and pollute nearly every level of our eco-system.

However, there are some who argue that U.S. landfills, using state of the art double lining requiring all landfills by law, protect the groundwater from contamination. Additionally, these landfills can be harvested for the methane gas produced by the decomposing waste as alternative energy capable of provided enough energy for neighboring towns. They further state that recycling is not minimizing this net pollution but rather creating a new, equally polluting industry offsetting any good recycling claims to accomplish such as the bleaching chemicals used in the manufacturing of recycled paper.

In other countries, they have a different practice. You can buy a bottle of water, return to the store for another, but you will charged extra if you don't bring back the original bottle for reuse. This must be the solution, one bottle for life!

The problem is that "over time, the bottles develop cracks and crevices where the bacteria can easily collect. It's important people swap out their bottles as much as possible". The article from Fox Oregon states that after only a couple days after throughly washing, "the bottle contained 4,100 bacteria colonies", twice the acceptable amount according to Coffey Laboratories in northeast Portland.

Of course the bottled water is just an example of reuse. Other former waste materials find a new use after their original intent is finished.

So what can we do? Make our products last longer, construct a more efficient recycling program, create a safer landfill and disposal system or is it something we have yet to think of?

YOUR RECYCLING IS SECRETLY DUMPED

Everybody, thanks to Mia for the first foray into a very important (and lately contentious) subject: Recycling.

As I'm sure Mia would agree, not every type of plastic is appropriate for re-use. This feels like the beginning of a spirited debate, so I thought I'd attempt to clarify a point regarding the re-use of plastic water bottles.

The typical water bottle is primarily a single-use container that isn't manufactured for continual re-usage. Specifically, the material is PETE #1 (Polyethylene Terephthalate) and breaks down in "lower barrier" applications, but this has more to do with the manufacturing of the bottle than the ability of the material to stand up to re-use.

Manufacturers use this type of plastic because it is a strong chemical barrier for liquids and acids, with good toughness and resistance to internal and external pressure. That makes it useful for different beverages under its primary conditions.

But in the case of water bottles, the IV (intrinsic viscosity) is based on the requirements of containing water and surviving impact, so this plastic is thinner and lighter weight, which results in breakdown.

Still, the base polymer PET (polyethylene) is a cost-effective material that can be molded into a wide variety of containers and tailored to the needs of the manufacturers based on strength, weight, clarity, and color of the final product. For this reason it can be used for many types of containers, including heavier juice bottles and water jugs, as well as new types of beer bottles.

Other forms of polyethylene plastics that are better suited to re-usage, given their chemical and material formulation, include:

- HDPE #2 (High Density Polyethylene): Milk jugs, oil bottles, margarine tubs

- PP #5 (Polypropylene): Rubbermaid products, yogurt containers, etc.

When washed with hot, soapy water there is little risk of bacterial contamination.

The "higher barrier" structures of these containers makes them less prone to deterioration, scratches, etc. that happens with single-use, lower barrier bottles. If not subjected to the intense heat of high-power dishwashers or microwaves (which can change any PET structure at a molecular level) these containers can support numerous re-usage without harm.

But if you want to be completely safe, don't use plastic at all - glass bottles are the most effective, chemically-neutral container for re-use or storage of water or other liquids.

Keep 'em coming, Mia!

Recycling is total Bullshit.
