The Age of Plastic

By Laurine Brown, PhD, MPH

When relatives of the sunken Titanic victims claimed salvaged belongings of loved ones-- ivory combs, pocket watches, spectacles, and other ordinary things--there was not a plastic item among them. Now 100 years later, can you imagine a day without plastic? Why look around now and surely you'll eyeball dozens of offspring from barrels of oil (yes, modern plastic is made from petroleum). Plastic has seeped into nearly every aspect of modern life. It's molded into our computers, phones, wires, pens, carpets, flooring, window blinds, water pipes, shower curtains, kitchen gadgets, credit cards, cars, planes, and even our clothes. The inventory seems endless. We define ourselves as the Information Age. But archeologists uncovering our mounds of rubble might better label us the Plastic Age.

Many of us have a love-hate relationship with plastic. On the one hand, we're addicted to the affordable and unbreakable luxuries that plastic offers. Why Tupperware alone transformed the face of leftovers by offering the busy housewife an idiotproof, childproof alternative to glass and ceramic. Now we can do things in a jiffy--we can even be mindless in our tasks without reprimand from a broken glass. Could we be flying, satelliting or moonwalking without plastic? And how would we mend our broken joints, valves, or limbs?

On the other hand, plastic is symbolic of "everything that's fake and wrong with the modern material world." Unlike natural heirlooms that age with grace, there's nothing sentimental about worn, cracked plastic. We toss it without the least attachment, except perhaps the hope that it will go away. And that's the problem. Like it or not, petroleum-derived plastics are designed not to biodegrade. And they don'. A notice to New York campers on decomposition times of typical camping litter notes: plastic container: 50-80 years; plastic foam: never.

So like it or not, plastic is here to stay. And so are the pollutants that are unfortunate consequences of our Plastic Age. Vinyl or polyvinylchloride (PVC) is the worst offender. Its manufacture marries petroleum with the poisonous gas chlorine, unintentionally releasing dioxin. Dioxin is an exotic and extremely persistent chemical accused of causing cancer, immune suppression, hormone disruption and infertility. When vinyl or PVC are burned (fire in a home or World Trade Center, or through garbage incineration), dioxin is also released. Adding fuel to the pollutant pile, the additives used to make plastic pliable (like phthalates) or firm (like bisphenol A or p-nonylphenol) may also be wreaking havoc with our hormones, especially estrogen. For example, some evidence is linking the early puberty in girls with these plasticizers. They easily "slip off" the plastic, entering the food they hold, our bodies, and our environment.

Some scientists claim it is time to phase out vinyl chloride. Happily, instead of petroleum we can craft plastic and plasticizers out of plants like soybeans that are more natural to our biology (thus more biodegradable). It's impossible to eliminate most plastic from daily life, but it's prudent for our health and that of our environment (which are intricately interconnected) to curb the use of some. At least avoid contact with certain plastics and food. In particular, try to avoid heating food in plastic because heating speeds leaching of additives into foods, especially fatty ones. You may find you need to be more mindful of your tasks as you handle more earthly elements like glass. And frankly, that can be a good thing.

Reduce the Use of Plastics

Reasons to Avoid Plastics as much as Possible

• They're made from petroleum, a non-renewable resource.
• Their production releases toxic chemicals into the environment.
• Hormone-disrupting chemicals can migrate from some plastics into food, water, air and our mouths.

  How to Avoid using Plastics

• Microwave in oven-proof glass or ceramic. Never let plastic wrap touch heated food.
• Replace plastic travel mugs with stainless steel for hot beverages.
• Store food in glass, ceramic, or stainless steel.
• For wrapped foods, best choices are butcher or waxed paper, wood-based cellulose bags (available from Seventh Generation).
• Avoid plastic cutlery, dinnerware, and styrofoam cups. Invest in reusable metal utensils and enamel picnicware, or look for recycled paper products.
• Bring your own take-out container to salad bars, delis, wherever they serve plastic.
• Bring your own cloth totes (or reuse plastic bags) when shopping.
• Buy in bulk. Avoid singe-use disposable packaging.

  Safer, Sounder Plastics to Choose

• When plastic can't be avoided check container bottoms for recycling codes (in triangle with chasing arrows); choose those easily recycled in your area, usually:

  #1 (PETE)

  #2 (HDPE)

• Choose non-PVC cling wrap (Glad and HandiWrap)

  Plastics to Avoid

• Avoid PVC vinyl whose manufacture and incineration releases toxic dioxins into the food chain.
• Avoid plastics that leach hormone-disrupting chemicals:

  #3 (PVC)

  #6 (PS)

  #7 ("Other", often polycarbonate)

• Avoid plastics that are not very recylable: #3 (PVC), #4 (LDPE), #5 (PP), #6 (PS), #7 (Other)
