The hazards of re-using plastic

Recently after undertaking a feel trip to the city Dump yard i saw the enormous plastic waste that was lying all over the place and also i could not help thinking about the reuse of plastic and after googling a bit i read this article.

Most types of plastic bottles are safe to reuse at least a few times if properly washed with hot soapy water. But recent revelations about chemicals in Lexan (plastic #7) bottles are enough to scare even the most committed environmentalists from reusing them (or buying them in the first place).

Chemicals May Contaminate Food and Drinks in Reused Plastic Bottles
Studies have indicated that food and drinks stored in such containers—including those ubiquitous clear Nalgene water bottles hanging from just about every hiker’s backpack—can contain trace amount of Bisphenol A (BPA), a synthetic chemical that interferes with the body’s natural hormonal messaging system.

Reused Plastic Bottles Can Leach Toxic Chemicals
The same studies found that repeated re-use of such bottles—which get dinged up through normal wear and tear and while being washed—increases the chance that chemicals will leak out of the tiny cracks and crevices that develop over time. According to the Environment California Research & Policy Center, which reviewed 130 studies on the topic, BPA has been linked to breast and uterine cancer, an increased risk of miscarriage, and decreased testosterone levels.

BPA can also wreak havoc on children’s developing systems. (Parents beware: Most baby bottles and sippy cups are made with plastics containing BPA.) Most experts agree that the amount of BPA that could leach into food and drinks through normal handling is probably very small, but there are concerns about the cumulative effect of small doses.

Even Plastic Water and Soda Bottles Should Not Be Reused
Health advocates also recommend not reusing bottles made from plastic #1 (polyethylene terephthalate, also known as PET or PETE), including most disposable water, soda and juice bottles. According to The Green Guide, such bottles may be safe for one-time use, but re-use should be avoided because studies indicate they may leach DEHP—another probable human carcinogen—when they are in less-than-perfect condition.

Millions of Plastic Bottles End Up in Landfills
The good news is that such bottles are easy to recycle; just about every municipal recycling system will take them back. But using them is nonetheless far from environmentally responsible: The nonprofit Berkeley Ecology Center found that the manufacture of plastic #1 uses large amounts of energy and resources and generates toxic emissions and pollutants that contribute to global warming. And even though PET bottles can be recycled, millions find their way into landfills every day in the U.S. alone.

Incinerating Plastic Bottles Releases Toxic Chemicals
Another bad choice for water bottles, reusable or otherwise, is plastic #3 (polyvinyl chloride/PVC), which can leach hormone-disrupting chemicals into the liquids they are storing and will release synthetic carcinogens into the environment when incinerated. Plastic #6 (polystyrene/PS), has been shown to leach styrene, a probable human carcinogen, into food and drinks as well.

Safe Reusable Bottles Do Exist
Safer choices include bottles crafted from safer HDPE (plastic #2), low-density polyethylene (LDPE, AKA plastic #4) or polypropylene (PP, or plastic #5). Aluminum bottles, such as those made by SIGG and sold in many natural food and natural product markets, and stainless steel water bottles are also safe choices and can be reused repeatedly and eventually recycled.

SOS from Planet Earth

With an advancement in science and technology we are developing and moving to the avenues which were unimaginable a few years back at a very rapid pace. We are using all the resources that were available to us from the planet Earth. The balance between what to use and how much to consume is something that we were not even concerned about till a few years back. Then the world started talking about the Kyoto Protocol. That to me is the first step that we started thinking about the planet and the consequences of what we have done till now. Still personally I don't think it is going to help us a lot talking about steps and talking about measures that the government must take to ensure the call from distressed Earth. The change should happen at the individual's level. We must come up with small steps that help us play our part in helping answer the problem we are into. May be I am just talking about limiting the use of Plastic bags, Petrol,Electricity and other things that help us reduce the external commodities we were adding in this palnet.
