Bye-Bye, BPA

BPA/ Phthalate-Free Shopping List

Part One: Drinking Bottles

It’s hot! Time to hydrate. And while you’re at it, every time you refill a reusable water bottle, rather than buy disposables, you’re helping the Earth’s health, too. If all Americans did so, we’d save the estimated 16 million barrels of oil used to make the bottled-water containers we bought last year. This from the August Harper’s Index, (, which also notes that twice as much water was used to make the containers as was drunk from them.

Choose the right reusable bottle, and you won’t get bit by the chemicals that can leach from some plastics in these sizzling dog days.

Bisphenol-A (BPA) has been found to cause developmental harm in animals, and there’s preliminary evidence of reproductive harm in women. And, while a family of plasticizers known as phthalates has long been linked to cancer and hormone disruption in lab animals, studies in 2005 and 2006 show some connection to genital abnormalities and lower testosterone in infant boys. This inspired a worried phone call from my brother Ethan Won, father of three young boys, ages 5 months, 4 and 6 years. “I’ve been hearing about all these chemicals coming out of plastics. Some plastics smell really bad, especially in the heat,” says Ethan, who lives in Honolulu, Hawaii. “And what about when we warm the baby’s bottle?”

A good question, as many clear plastic baby bottles, along with some of those pretty Nalgene Lexan bottles in transparent jellybean colors, are made of polycarbonate (recycling code #7) plastic, which has been found to leach BPA when heated, worn or scratched. “We always want kids’ products to be safe in any way they’re used,” says Sonya Lunder, M.D., a scientist with the Environmental Working Group (, which encourages consumers to seek alternatives to polycarbonate bottles, especially for babies and children.As Greenerpenny reader Bridget Collins writes,“I am very interested in shopping for products that do not contain BPAs. My kids are active and use water bottles several times a day!”

While it doesn’t accumulate in our bodies,“with BPA detected in about 95% of people in a recent CDC [U.S. Centers for Disease Control] test, we can assume that most of the American population has daily exposure,” Lunder says. These chemicals may also play a role in the development of obesity and diabetes, according to a 2006 Spanish study of BPA and a March, 2007 article on phthalates in Environmental Health Perspectives. Even if fat is “contagious,” as raised by a study in the New England Journal of Medicine last week, it’s far less extreme to drop risky plastics than an overweight friend.

Below are the safest, greenest and most affordable reusable bottles we could find. Pennypinchers, rejoice: In addition to keeping disposables out of landfills, and conserving the tons of carbon dioxide otherwise released in shipping, bypassing bottled water can save each of us about $1,400 a year, by the estimate of New York City officials.

Top Pick: Stainless Steel
Go plastic- and petrochemical- free with 100% stainless steel, the most recycled metal.

Perfect for kids or those of us who feel oppressed by heavy totes, Klean Kanteen’s lightweight, 12 oz volume stainless bottles are the same size as soda cans; caps have a stainless interior and non-leaching polypropylene (#5) top. From $13.95 to $22.95 for a 40-ouncer. For better totability, order a loop cap with a hole in it, or neoprene insulating sling or sleeve that snaps around pack straps, bike or stroller bars. At

Slightly cheaper stainless bottles are $11.95 for 27 oz or $19.95 for 40 oz from,/ which also sells Klean Kanteens.

Thermos 18 oz. stainless steel Hydration Bottle with stainless interior and exterior vacuum insulation walls; $17 at; insulated sleeves also sold.

Preferable Plastics

You can identify better plastics by the recycling code numbers stamped in them. Look for reusable bottles made of:
#2 (HDPE, high-density polyethylene, the most widely recyclable)
#4 (LDPE, low-density polyethylene) or
#5 (PP, polypropylene).
These plastics have not been found to release BPA or phthalates.

On the other hand, most single-use water bottles are made of #1 polyethylene terephthalate (PET or PETE). These bottles, if old, reused or heated, may release two phthalates: Di(2-ethylhexyl adipate), or DEHA, and benzyl butyl phthalate (BBP), which are possible human carcinogens, according to the U.S. Environmental Protection Agency. And, although this plastic is easily recyclable, about 90% of the PET water bottles sold each year wind up in landfills. After all, they’re made to be tossed!

Sigg Aluminum Bottles

No doubt about it, these lined aluminum bottles are light, beautiful and strong. And doubts about possible BPA leaching from Sigg’s patented epoxy linings have been laid to rest by tests commissioned by the company in May, 2007. After water was heated in the bottles for 3 days, no detectable residues of BPA were found, and EWG, as of this writing, has agreed to remove from its website its warnings about Sigg.

Available in 4 colors, the .6 liter Traveler Classic is $18, and .3 liter Travelers or children’s bottles picturing friendly mammals, dinosaurs, vehicles and the sun, are $15.95, with some NOW ON SALE for $10.95; patterned .4 liter kids’ versions cost $17.95, all at

Given the environmental ravages caused by the mining of bauxite for aluminum, however, and the 75% more energy consumed in the production of aluminum, according to the Worldwatch Institute, from raw materials as opposed to recycled metal, reusable bottles could be a lot greener if they were made from post-consumer-recycled stock.
